In this guide, we are going to explain in detail, How to Install NextCloud On Ubuntu 24.04 LTS. This is a detailed step by step guide. during the installation, we have focused on increasing the performance and security of the system.
What is Nextcloud?
Nextcloud is a self-hosted collaboration platform designed to enhance productivity through integrated services like Files, Talk, Groupware, and Office. It offers functionality similar to Dropbox, Office 365, or Google Drive when used with office suites like Collabora Online or OnlyOffice.

![nextcloud ubuntu 24.04 photos view](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud_ubuntu_24.04_photos_view.png)
Nextcloud has four main products. Files provides self-hosted file storage and synchronization. Talk offers private audio/video conferencing and chat. Groupware includes productivity tools like Calendar and Mail, and Office provides an online office suite for collaborative document editing.
Nextcloud can be hosted in the cloud or on-premises, offering flexible deployment options. It allows storing documents on private servers or trusted data centers, ensuring greater control and security.
Below we provided a step by step guide on How to Install NextCloud On Ubuntu 24.04 LTS. We completed in 14 steps. Each steps are mandatory to complete before go to next step.
![nextcloud install ubuntu 24.04 3phase](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud_install_ubuntu_24.04_3phase-1024x641.png)
We divided the installation into three main phases. First, we provided the steps for “Basic Nextcloud Setup” then we did the “Performance Tuning“. Finally, we provided steps for “Systems Security“.
Phase1: | |
Basic Nextcloud Setup |
|
In this Phase we Have 5 Steps: | ![]() |
1. System Update and Upgrade | |
2. Install Apache and PHP Modules | |
3. Install MariaDB Database | |
4. Prepare Nextcloud archive | |
5. Install Nextcloud from CLI | |
Step1: Update and Upgrade the system.
1. Update and Upgrade the Ubuntu Packages
apt update && apt upgrade -y
Step2: Install Apache2 and PHP Modules.
1. install Apache2
apt install apache2 -y
3. Install PHP and other Dependencies
apt install php php-common libapache2-mod-php php-bz2 php-gd php-mysql \
php-curl php-mbstring php-imagick php-zip php-common php-curl php-xml \
php-json php-bcmath php-xml php-intl php-gmp zip unzip wget -y
4. Enable required Apache modules
a2enmod env rewrite dir mime headers setenvif ssl
5. Now, Restart, Enable and Check Apache is Running Properly.
systemctl restart apache2
systemctl enable apache2
6. Apache service should be in running state.
root@nc:~# systemctl status apache2
● apache2.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/apache2.service;

CGroup: /system.slice/apache2.service
├─16319 /usr/sbin/apache2 -k start
├─16326 /usr/sbin/apache2 -k start
6. Check modules are loaded on Apache (Output omitted)
root@nc:~# apache2ctl -M
Loaded Modules:
core_module (static)
so_module (static)
watchdog_module (static)
http_module (static)
log_config_module (static)
............
Step3: Install and Configure MariaDB Server
1. Install mariadb-server package
apt install mariadb-server -y
2. Login to MariaDB, Just type the below command, It will drop you to MySQL Prompt.
mysql
root@nc:~# mysql
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 1131
Server version: 10.11.7-MariaDB-2ubuntu2 Ubuntu 24.04
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
3. Create Database and User for Nextcloud and Provide User Permissions.
CREATE USER 'ncloud'@'localhost' IDENTIFIED BY 'Sh@do5!d';
CREATE DATABASE ncloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
GRANT ALL PRIVILEGES ON ncloud.* TO 'ncloud'@'localhost';
FLUSH PRIVILEGES;
quit;
4. Now, restart and enable MariaDB service.
systemctl restart mariadb
systemctl enable mariadb
5. check MariaDB is Running.
root@nc:~# systemctl status mariadb
● mariadb.service - MariaDB 10.11.7 database server
Loaded: loaded (/usr/lib/systemd/system/mariadb.service;
enabled; preset: enabled)

CPU: 573ms
CGroup: /system.slice/mariadb.service
└─17589 /usr/sbin/mariadbd
Step4: Download Nextcloud, Unzip and Permission
Now download the latest Nextcloud archive. Go to the Nextcloud Download Page Or you can download from this direct link.
1. Download and unzip in the /var/www/html folder
cd /var/www/html
wget https://download.nextcloud.com/server/releases/latest.zip
unzip latest.zip
2. Remove the zip file, which is not necessary now.
rm -rf latest.zip
3. Change the ownership of the nextcloud directory to the HTTP user.
chown -R www-data:www-data /var/www/html/nextcloud/
Step5: Install Nextcloud From Command Line
Now, we will install nextcloud on ubuntu 24.04 LTS from the command line. Configuration will be silent and quicker than going through the web GUI setup. we need to provide database and admin credentials for Command Line installation. you can visit this page to know more about nextcloud CLI installation.
1. Run the below command to install nextcloud (provide your own credentials)
cd /var/www/html/nextcloud
sudo -u www-data php occ maintenance:install --database \
"mysql" --database-name "ncloud" --database-user "ncloud" --database-pass \
'Sh@do5!d' --admin-user "admin" --admin-pass "password"
If everything goes well the command will output “Nextcloud was successfully installed”.
2. Nextcloud allows access only from localhost, it could through error “Access through untrusted domain”. we need to allow accessing Nextcloud by using ip or domain name.
vi /var/www/html/nextcloud/config/config.php
'trusted_domains' =>
array (
0 => 'localhost',
1 => 'nc.mailserverguru.com', // we Included the Sub Domain
),
.....
:x
3. Configure Apache to load Nextcloud from the /var/www/html/nextcloud folder.
vi /etc/apache2/sites-enabled/000-default.conf
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/nextcloud
<Directory /var/www/html/nextcloud>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
4. Now restart Apache
systemctl restart apache2
Now, Go to the Browser and type http://[ip or fqdn] of the server, The below Nextcloud login page will appear.
![ubuntu 24.04 nextcloud login](https://mailserverguru.com/wp-content/uploads/2024/06/ubuntu-24.04-nextcloud-login.png)
This is it for the 1st phase. We have seen How to install Nextcloud on Ubuntu 24.04 LTS. Now we are going to work on the performance and security.
In the 2nd phase, we will go for the performance tuning, we will install PHP-FPM for PHP files processing, then we will enable various caching system to increase the application performance.
Phase2: | |
Performance Tuning |
|
In this Phase we Have 5 Steps: | ![]() |
1. Install PHP-FPM with Apache | |
2. Create info.php Page | |
3. Enable OPCache & OPCache-JIT | |
4. Enable APCu in PHP | |
5. Configure Redis Cache | |
Step6: Install and Configure PHP-FPM with Apache
Here we will install PHP-FPM, which is faster than the mpm-prefork module, which is the default method of executing php files on Apache.
1. Install PHP-FPM
apt install php8.3-fpm
2. Check the PHP-FPM is running, its version and Socket is created.
service php8.3-fpm status
php-fpm8.3 -v
ls -la /var/run/php/php8.3-fpm.sock
3. Disable mod_php and prefork module
a2dismod php8.3
a2dismod mpm_prefork
4. Enable PHP-FPM
a2enmod mpm_event proxy_fcgi setenvif
a2enconf php8.3-fpm
5. Restart Apache to reload all the modules and configurations
systemctl restart apache2
Now, for file upload size and performance settings, we need to tweak some php.ini settings listed below in the /etc/php/8.3/fpm/php.ini file. You can assign your own values depending on your environment.
upload_max_filesize = 64M
post_max_size = 96M
memory_limit = 512M
max_execution_time = 600
max_input_vars = 3000
max_input_time = 1000
6. check the current values.
grep -E "upload_max_filesize|post_max_size|memory_limit|max_execution_time|max_input_vars|max_input_time" /etc/php/8.3/fpm/php.ini
7. Instead of manual change, you can execute the below command to change at once. it will save time.
sed -i 's/^upload_max_filesize.*/upload_max_filesize = 64M/; s/^post_max_size.*/post_max_size = 96M/; s/^memory_limit.*/memory_limit = 512M/; s/^max_execution_time.*/max_execution_time = 600/; s/^;max_input_vars.*/max_input_vars = 3000/; s/^max_input_time.*/max_input_time = 1000/' /etc/php/8.3/fpm/php.ini
Now, we need update PHP-FPM pool Configurations at /etc/php/8.3/fpm/pool.d/www.conf, below are some optimum values, but you should assign your own values.
pm.max_children = 64
pm.start_servers = 16
pm.min_spare_servers = 16
pm.max_spare_servers = 32
8. Check current values.
grep -E "pm.max_children|pm.start_servers|pm.min_spare_servers|pm.max_spare_servers" /etc/php/8.3/fpm/pool.d/www.conf
9. Change all the values at once with the below command.
sed -i 's/^pm.max_children = .*/pm.max_children = 64/; s/^pm.start_servers = .*/pm.start_servers = 16/; s/^pm.min_spare_servers = .*/pm.min_spare_servers = 16/; s/^pm.max_spare_servers = .*/pm.max_spare_servers = 32/' /etc/php/8.3/fpm/pool.d/www.conf
10. Now, restart PHP-FPM to apply all the changes.
service php8.3-fpm restart
Now, Insert the below code to apache’s default site configuration file /etc/apache2/sites-enabled/000-default.conf, it will direct apache to handover the php file processing to PHP-FPM.
<FilesMatch ".php$">
SetHandler "proxy:unix:/var/run/php/php8.3-fpm.sock|fcgi://localhost/"
</FilesMatch>
11. After providing the code, apache’s default site configuration will look like the below snippet.
vi /etc/apache2/sites-enabled/000-default.conf
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/nextcloud
<Directory /var/www/html/nextcloud>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
<FilesMatch ".php$">
SetHandler "proxy:unix:/var/run/php/php8.3-fpm.sock|fcgi://localhost/"
</FilesMatch>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
12. Now, Restart Apache to take the change.
systemctl restart apache2
Step7: Create info.php Page for PHP feature check
Create an info.php page, it will show us whether PHP-FPM, OPCache, APCu are enabled with the PHP.
cd /var/www/html/nextcloud
vi info.php
<?php phpinfo(); ?>
:x
Now, Browse [URL]/info.php. if the PHP-FPM is enabled on the PHP. it will show “Server API FPM/FastCGI”
![nextcloud ubuntu 24.04 php-fpm](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud-ubuntu-24.04-php-fpm-1024x240.png)
Step8: Enable OPCache in PHP
Opcache is a caching engine for PHP. It stores precompiled script bytecode in shared memory, so parsing PHP scripts on each request won’t be necessary. It increases PHP file execution and website loading performance. Opcache is enabled by default.
1. Check it is running or not from the [URL]/info.php file previously we created.
![nextcloud ubuntu 24.04 opcache](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud-ubuntu-24.04-opcache-1024x173.png)
2. Opcache JIT (Just-In-Time) compilation is an important feature. JIT compilation improves PHP performance by compiling code into machine language at runtime, rather than interpreting it each time it’s executed. This can significantly enhance the performance of CPU-intensive tasks. So it will be very effective to enable it to increase nextcloud performance.
vi /etc/php/8.3/fpm/conf.d/10-opcache.ini
zend_extension=opcache.so
opcache.enable_cli=1
opcache.jit=on
opcache.jit = 1255
opcache.jit_buffer_size = 128M
:x
“opcache.enable_cli” this option is not mandatory, but would be very useful if we use nextcloud cli commands or scripts frequently.
3. Restart PHP-FPM to take effect the change.
service php8.3-fpm restart
Now Browse info.php again, it will show all the above features enabled.
![](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud-ubuntu-24.04-opcache-zit-1024x388.png)
Step9: Enable APCu in PHP
APCu is the user data caching. It is a local cache for systems. Nextcloud uses this for memory caching. we need to enable APCu on CLI which is disabled by default which could cause issues with nextcloud’s cron jobs.
1. Install APCu
apt install php8.3-apcu
2. Enable APCu on CLI.
vi /etc/php/8.3/fpm/conf.d/20-apcu.ini
extension=apcu.so
apc.enable_cli=1
:x
3. Now, Restart PHP-FPM and Apache
systemctl restart php8.3-fpm
systemctl restart apache2
Now, Check the [URL]/info.php again, it will show the “APCu support Enabled”
![](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud-ubuntu-24.04-apcu-1024x174.png)
4. Now, Configure Nextcloud to use APCu for memory caching.
vi /var/www/html/nextcloud/config/config.php
'memcache.local' => '\OC\Memcache\APCu',
:x
Step10: Install and Configure Redis Cache
In Nextcloud, Redis is used for local and distributed caching as well as transactional file locking. we used APCu for Local Caching which is faster than Redis. We will use Redis for File locking. Nextcloud’s Transactional File Locking mechanism locks files to avoid file corruption during normal operation.
1. Install Redis Server and Redis php extension
apt install redis-server php-redis -y
2. Start and Enable the Redis service.
systemctl start redis-server
systemctl enable redis-server
2. Configure Redis to use Unix Socket than ports
vi /etc/redis/redis.conf
port 0
unixsocket /var/run/redis/redis.sock
unixsocketperm 770
:x
3. Add Apache user to the Redis group
usermod -a -G redis www-data
4. Configure Nextcloud for using Redis for File Locking
vi /var/www/html/nextcloud/config/config.php
'filelocking.enabled' => 'true',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => [
'host' => '/var/run/redis/redis.sock',
'port' => 0,
'dbindex' => 0,
'password' => '',
'timeout' => 1.5,
],
:x
5. Enable Redis session locking in PHP
vi /etc/php/8.3/fpm/php.ini
redis.session.locking_enabled=1
redis.session.lock_retries=-1
redis.session.lock_wait_time=10000
:x
6. Restart Redis, PHP-FPM and Apache
systemctl restart redis-server
systemctl restart php8.3-fpm
systemctl restart apache2
7. You can check the features are enabled on PHP
![](https://mailserverguru.com/wp-content/uploads/2024/06/nextcloud-ubuntu-24.04-redis-1024x287.png)
We can check Redis use, (by enabling the Redis port in the Redis configuration) by running the command “redis-cli MONITOR“, during Nextcloud loading it will show live data on the screen.
Now, that we have finished Performance improvement steps. We are going to work for the Security, First of all, we will install an SSL certificate for Nextcloud.
Phase3: | |
Systems Security |
|
In this Phase we Have 4 Steps: | ![]() |
1. Install SSL and enable HTTP2 |
|
2. Strict Transport Security |
|
3. Enable Pretty URL’s |
|
4. Protection with Firewall |
|
Step11: Install SSL and Enable HTTP2
1. We will install the LetsEncrypt certificate, so, first, we need the Certbot tools.
apt install certbot python3-certbot-apache -y
2. with the Certbot tool, let’s request a Certificate for our domain.
certbot --apache -d nc.mailserverguru.com

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
3. Enable apache HTTP2 module
a2enmod http2
4. Configure default SSL site for the http2 protocols
vi /etc/apache2/sites-enabled/000-default-le-ssl.conf
<VirtualHost *:443>
Protocols h2 http/1.1
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/nextcloud
......
:x
5. Now restart Apache to enable the HTTP2 Protocol
systemctl restart apache2
4. Test the http2 protocol, by sending an http2 request to the web server.
curl -I --http2 -s https://nc.mailserverguru.com/ | grep HTTP
HTTP/2 200
Or, we can Inspect the Browser while accessing Nextcloud URL, we can easily see the protocol column from the Network tab, and it will show h2 as the protocol which is http2.
![install nextcloud ubuntu 24.04 http2](https://mailserverguru.com/wp-content/uploads/2024/06/install_nextcloud_ubuntu_24.04_http2-1024x745.png)
Step12: Enable Strict Transport Security
HTTP Strict Transport Security, which instructs browsers not to allow any connection to the Nextcloud instance using HTTP, prevents man-in-the-middle attacks. provide the below code in the virtual host configuration for the default SSL.
<IfModule mod_headers.c>
Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"
</IfModule>
vi /etc/apache2/sites-enabled/000-default-le-ssl.conf
<VirtualHost *:443>
ServerName nc.mailserverguru.com
<IfModule mod_headers.c>
Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"
</IfModule>
</VirtualHost>
Step13: Enable Pretty URL’s
Pretty URLs remove the "index.php
” part in all Nextcloud URLs. It will make URLs shorter and prettier.
vi /var/www/html/nextcloud/config/config.php
'htaccess.RewriteBase' => '/',
:x
This command will update the .htaccess file for the redirection
sudo -u www-data php --define apc.enable_cli=1 /var/www/html/nextcloud/occ maintenance:update:htaccess
Step14: Access Protection with Firewall.
No server can maintain good security without an active firewall policy. after install and configure nextcloud, we have to allow traffic only to specific ports, rest of the ports should be close to the world. if we add more nextcloud apps later, we might need to open new ports to the firewall later.
1. execute the following code’s for the basic Iptables firewall setup.
#!/bin/bash
# Flush all existing rules
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
# Allow loopback traffic
iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT
# Allow established and related incoming traffic
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
# Allow all outgoing traffic
iptables -A OUTPUT -j ACCEPT
# Allow incoming traffic on port 22 (SSH)
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
# Allow incoming traffic on port 80 (HTTP)
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
# Allow incoming traffic on port 443 (HTTPS)
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
# Allow ICMP (ping)
iptables -A INPUT -p icmp -j ACCEPT
# Apply security hardening
# Protect against SYN flood attacks
iptables -A INPUT -p tcp ! --syn -m conntrack --ctstate NEW -j DROP
iptables -A INPUT -p tcp --tcp-flags ALL NONE -j DROP
iptables -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP
iptables -A INPUT -p tcp --tcp-flags SYN,RST SYN,RST -j DROP
# Protect against ping flood (limit to 1 ping per second with burst of 3)
iptables -A INPUT -p icmp --icmp-type echo-request -m limit --limit 1/s --limit-burst 3 -j ACCEPT
# Protect against IP spoofing
iptables -A INPUT -s 10.0.0.0/8 -j DROP
iptables -A INPUT -s 172.16.0.0/12 -j DROP
iptables -A INPUT -s 192.168.0.0/16 -j DROP
iptables -A INPUT -s 127.0.0.0/8 -j DROP
iptables -A INPUT -s 224.0.0.0/4 -j DROP
iptables -A INPUT -s 240.0.0.0/5 -j DROP
iptables -A INPUT -s 0.0.0.0/8 -j DROP
iptables -A INPUT -s 169.254.0.0/16 -j DROP
# Log dropped packets (optional)
iptables -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7
# Drop all other inbound traffic
iptables -A INPUT -j DROP
# End of script
2. Apply the Iptables Rules through script, follow the below steps.
vi nextcloud_iptables.sh
# copy Iptables Rules from above and Paste here.
:x
# Make the script executable
chmod +x nextcloud_iptables.sh
# Run the script
./nextcloud_iptables.sh
3. Save the rules permanently. It will reload across reboot.
apt install iptables-persistent netfilter-persistent -y
systemctl enable netfilter-persistent
systemctl start netfilter-persistent
4. If you Update the Rules, you have to save it, so that it can be reloaded across reboot
iptables-save > /etc/iptables/rules.v4
[Note]: Regarding the SSH port, you should only allow your specific node or network to remote access to your nextcloud server.
So, this is it..
We have done our Complete Guide on How to Install NextCloud On Ubuntu 24.04 LTS.
Enjoy !!
