How to install Nextcloud v 13 on Centos 7 with php 7

At first, please update your centos. Every command I used, is used as root user 😉

yum -y update

Installing database server MariaDB

Next, we install and create empty database for our nextcloud. Then we start it and enable for autostart after boot.
If you wish, you can skip installations of MariaDB and you can use built-in SQLite. Then you can continue with installing apache web server.

yum -y install mariadb mariadb-server
...
systemctl start mariadb
systemctl enable mariadb

Now, we run post installation script to finish setting up mariaDB server:

mysql_secure_installation
...
Enter current password for root (enter for none): ENTER
Set root password? [Y/n] Y
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Now, we can create a database for nextcloud.

mysql -u root -p
...
CREATE DATABASE nextcloud;
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextclouduser'@'localhost' IDENTIFIED BY 'YOURPASSWORD';
FLUSH PRIVILEGES;
exit;

Installing Apache Web Server with ssl (letsencrypt)

Now, we install Apache web server, and we start it and enable for autostart after boot:

yum install httpd -y
systemctl start httpd.service
systemctl enable httpd.service

Now, we install ssl for apache and allow https and httpd (for redirect) service for firewall:

yum -y install epel-release
yum -y install httpd mod_ssl
...
firewall-cmd --zone=public --permanent --add-service=https
firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --reload
systemctl restart httpd.service
systemctl status httpd

Now we can access our server via http://our.server.sk or self-signed certificate on https://our.server.sk

If we want signed certificate from letsencrypt, we can do it with next commands. Certboot will ask some questions, so answer them.

yum -y install python-certbot-apache
certbot --apache -d our.server.sk

If we are good, we can see:

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/example.com/fullchain.pem.
...

Then, we must edit our ssl.conf or our  virtual-host to see this certificates. And we can test our page with this.

Install PHP 7

The creators of nextcloud recommends at minimal PHP 7.0.
Now we must add some additional repositories for php v. 7:

yum install https://$(rpm -E '%{?centos:centos}%{!?centos:rhel}%{rhel}').iuscommunity.org/ius-release.rpm
yum install yum-plugin-replace
yum repolist # show enabled repositories
yum repolist disabled #show disabled repositories

And we can install php 7.0:

yum install php70u php70u-dom php70u-mbstring php70u-gd php70u-pdo php70u-json php70u-xml php70u-zip php70u-curl php70u-mcrypt php70u-pear setroubleshoot-server bzip2 php70u-mysqlnd.x86_64 php70u-ldap.x86_64 unzip php70u-pecl-apcu.x86_64 mod_php70u.x86_64 php70u-opcache.x86_64 php70u-pecl-memcached.x86_64 php70u-process.x86_64

Check in:

php --ini |grep Loaded
Loaded Configuration File:         /etc/php.ini
php -v
PHP 7.0.27 (cli) (built: Apr 15 2017 07:09:11) ( NTS )
Copyright (c) 1997-2017 The PHP Group

In my case, I will use nextcloud as my backup device, so I increase the default upload limit to 200MB.

sed -i "s/post_max_size = 8M/post_max_size = 200M/" /etc/php.ini
sed -i "s/upload_max_filesize = 2M/upload_max_filesize = 200M/" /etc/php.ini

Restart web server:

systemctl restart httpd

Installing Nextcloud

At first, I install wget tool for download and unzip:

 yum -y install wget unzip

Now we can download nextcloud (at this time the latest version is 11.0.3). And extract it from archive to final destination. Then we change ownership of this directory:

wget https://download.nextcloud.com/server/releases/nextcloud-13.0.0.zip
...
unzip nextcloud_konfs/nextcloud-13.0.0.zip -d /var/www/html/
...
chown -R apache:apache /var/www/html/nextcloud/

If you have enabled SELinux, refer to nextcloud admin manual, you can run into permissions problems. Run these commands as root to adjust permissions:

semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/data(/.*)?'
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/config(/.*)?'
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/apps(/.*)?'
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/.htaccess'
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/.user.ini'
restorecon -Rv '/var/www/html/nextcloud/'

And finally, we can access our nextcloud and set up administrators password via our web: https://you-ip/nextcloud
Now you must complete the installation via web interface. Set Administrator’s password and locate to MariaDB with used credentials:

Database user: nextclouduser
Database password: YOURPASSWORD
Database name: nextcloud
host: localhost

In my case, I must create a DATA folder under out nextcloud, mount nfs backend for this data and set permissions.

mkdir /var/www/html/nextcloud/data
chown apache:apache data/ -R
setsebool -P httpd_use_nfs 1
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/data(/.*)?'
restorecon -Rv '/var/www/html/nextcloud/'

Now create an nextcloud configuration file fort apache:

vim /etc/httpd/conf.d/nextcloud.conf
<Directory /var/www/html/nextcloud/>
 Options +FollowSymlinks
 AllowOverride All

<IfModule mod_dav.c>
 Dav off
 </IfModule>

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^/$ /index.php/login
 SetEnv HOME /var/www/html/nextcloud
 SetEnv HTTP_HOME /var/www/html/nextcloud
</Directory>

#####################################################
<VirtualHost _default_:80>

For nicer access, I created a permanent rewrite rule for my  Nextcloud root folder.

Now restart apache and add permisions for apache, to sen emails and work with LDAP:

systemctl restart httpd.service
setsebool -P httpd_can_sendmail on
setsebool -P httpd_can_connect_ldap on

Enable updates via the web interface

To enable updates via the web interface, you may need this to enable writing to the directories:

setsebool httpd_unified on

When the update is completed, disable write access:

setsebool -P httpd_unified off
