How to Install NextCloud on CentOS 7

In this article, you will get some information on the installation of NextCloud on CentOS 7 with Alibaba Cloud ECS.

NextCloud is a free and open source self-hosted alternative to Dropbox or Google Drive. It lets you host your files onto your own private server, providing you full control over your data.

Prerequisite

  1. A new ECS instance with CentOS 7.4 as the operating system.
  2. Connect to your ECS instance and log in as the root user.
  3. A domain name which is pointed towards your ECS instance.

Once you are logged into your CentOS 7 instance, run the following command to update your base system with the latest available packages.

yum -y update

Create a new user.

adduser nextcloud
passwd nextcloud

Add the user to sudo group and switch to the newly created user.

usermod -aG wheel nextcloud
sudo su - nextcloud

Install Nginx with PHP 7

As of now, Nextcloud supports PHP version 7.0 and 7.1. In this tutorial, we will install PHP 7.1. Install EPEL and Remi repository so that we can install the pre-built PHP packages directly.

sudo yum -y install epel-release yum-utils nano unzip
sudo rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum-config-manager --enable remi-php71

Install Nginx web server and PHP 7.1 along with the required PHP modules.

sudo yum -y install nginx php php-fpm php-mysqlnd php-ctype php-dom php-gd php-iconv php-json php-libxml php-mbstring php-posix php-xml php-zip php-openssl php-zlib php-curl php-fileinfo php-bz2 php-intl php-mcrypt php-ftp php-exif php-gmp php-memcached php-imagick

Edit the loaded PHP configuration file.

sudo nano /etc/php.ini

Set the appropriate time zone and memory limit. If you want, you can use -1 as the memory limit, which will remove the limits on the amount of memory a script may consume. Uncomment and set 0 to the value of cgi.fix_pathinfo and increase the file upload limits. Once you have updated the parameters, the updates should look like as shown below.

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
memory_limit = 512M

...    
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone =Asia/Kolkata

...
cgi.fix_pathinfo=0

...
post_max_size = 512M

...
upload_max_filesize = 512M

Once you have done configuring php.ini, open the php-fpm configuration file.

sudo nano /etc/php-fpm.d/www.conf

Look for the user and group parameters and change it from apache to nginx. Find listen = 127.0.0.1:9000 file to comment it out and append listen = /var/run/php-fpm/php-fpm.sock just below it. Finally, uncomment listen.owner and change its value from nobody to nginx. Once you have updated the parameters, the updates should look like as shown below.

user = nginx
group = nginx

...    

;listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock

...

listen.owner = nginx
listen.group = nginx

Also, search for the following line and uncomment them to enable php environment variables.

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

Save the file and exit from the editor. Now create a new directory to store the PHP session data.

sudo mkdir -p /var/lib/php/session
sudo chown nginx:nginx -R /var/lib/php/session/

Set appropriate permission and ownership to php-fpm socket file.

sudo chown nginx:nginx /var/run/php-fpm/php-fpm.sock
sudo chmod 660 /var/run/php-fpm/php-fpm.sock

Now, start php-fpm and enable it to automatically start at boot time.

sudo systemctl restart php-fpm
sudo systemctl enable php-fpm

Also, start Nginx web server and enable it to automatically start at boot time.

sudo systemctl restart nginx
sudo systemctl enable nginx

Now you have installed Nginx with php 7 successfully, then you can download NextCloud, setup SSL, setup mySql database, finalize the web-based installation and configure Cron Job as this tutorial shows.
