安装

In this install tutorial we will be deploying CentOS 7.5, PHP 7.2, MariaDB, Redis as memcache and Nextcloud running on Apache.

Start off by installing a CentOS 7 minimal install. This should provide a sufficient platform to run a successful Nextcloud instance.

First install some dependencies you will be needing during installation, but which will also be useful in every day use situations:

yum install -y epel-release yum-utils unzip curl wget \
bash-completion policycoreutils-python mlocate bzip2

Now make sure your system is up to date:

yum update -y

Apache:

yum install -y httpd

Create a virtualhost file and add the following content to it:

vi /etc/httpd/conf.d/nextcloud.conf

<VirtualHost *:80>
  DocumentRoot /var/www/html/
  ServerName  your.server.com

<Directory "/var/www/html/">
  Require all granted
  AllowOverride All
  Options FollowSymLinks MultiViews
</Directory>
</VirtualHost>

Make sure the apache web service is enabled and started:

systemctl enable httpd.service
systemctl start httpd.service

PHP:

Next install the PHP modules needed for this install. Remember, because this is a limited basic install, we only install the neccessary modules, not all of them. If you are making a more complete install, please refer to PHP module list at the top of this page.:

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

yum install -y php72w php72w-cli php72w-common php72w-curl php72w-gd \
php72w-mbstring php72w-mysqlnd php72w-process php72w-xml php72w-zip \
php72w-opcache php72w-pecl-apcu php72w-intl php72w-pecl-redis php72w-pecl-imagick

Database

As mentioned, we will be using MySQL/MariaDB as our database.:

yum install -y mariadb mariadb-server

Make sure the database service is enabled to start at boot time.:

systemctl enable mariadb.service
systemctl start mariadb.service

Installing Nextcloud

Nearly there, so keep at it, you are doing great!

Now download the archive of the latest Nextcloud version:

• Go to the Nextcloud Download Page.
• Go to Download Nextcloud Server > Download > Archive file for server owners and download either the tar.bz2 or .zip archive.
• This downloads a file named nextcloud-x.y.z.tar.bz2 or nextcloud-x.y.z.zip (where x.y.z is the version number).
• Download its corresponding checksum file, e.g. nextcloud-x.y.z.tar.bz2.md5, or nextcloud-x.y.z.tar.bz2.sha256.

Verify the MD5 or SHA256 sum:

md5sum -c nextcloud-x.y.z.tar.bz2.md5 < nextcloud-x.y.z.tar.bz2
sha256sum -c nextcloud-x.y.z.tar.bz2.sha256 < nextcloud-x.y.z.tar.bz2
md5sum  -c nextcloud-x.y.z.zip.md5 < nextcloud-x.y.z.zip
sha256sum  -c nextcloud-x.y.z.zip.sha256 < nextcloud-x.y.z.zip

You may also verify the PGP signature:

wget https://download.nextcloud.com/server/releases/nextcloud-x.y.z.tar.bz2.asc
wget https://nextcloud.com/nextcloud.asc
gpg --import nextcloud.asc
gpg --verify nextcloud-x.y.z.tar.bz2.asc nextcloud-x.y.z.tar.bz2

For the sake of the walk-through, we grabbed the latest version of Nextcloud in the form a zip file, confirmed the download with the above-mentioned command, and now we will extract it:

unzip nextcloud-*.zip

Copy the content over to the root directory of your webserver. In our case, we are using apache so it will be /var/www/html/:

cp -R nextcloud/ /var/www/html/

During the install process, no data folder is created, so we will create one manually to help with the installation wizard:

mkdir /var/www/html/nextcloud/data

Make sure that apache has read and write access to the whole nextcloud folder:

chown -R apache:apache /var/www/html/nextcloud

Restart apache:

systemctl restart httpd.service

Create a firewall rule for access to apache:

firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload

Redis:

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

SELinux

Again, there is an extensive write-up done on SELinux which can be found at SELinux configuration, so if you are using SELinux in Enforcing mode, please run the commands suggested on that page. The following commands only refers to this tutorial:

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'
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud/3rdparty/aws/aws-sdk-php/src/data/logs(/.*)?'

restorecon -R '/var/www/html/nextcloud/'

setsebool -P httpd_can_network_connect on

If you need more SELinux configs, refer to the above-mentioned URL, return to this tutorial.

Once done with with SELinux, please head over to http://your.server.com/nextcloud and follow the steps as found Installation wizard, where it will explain to you exactly how to proceed with the final part of the install, which is done as admin user through your web browser.

Note

If you use this tutorial, and you see warnings in the web browser after installation about OPcache not being enabled or configured correctly, you need to make the suggested changes in /etc/php.d/opcache.ini for the errors to disappear. These warnings will be on the Admin page, under Basic settings.

Because we used Redis as a memcache, you will need a config similar to the following example in /var/www/html/nextcloud/config/config.php which is auto-generated when you run the online installation wizard mentioned earlier.

Example config:

'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\APCu',
'redis' => array(
  'host' => 'localhost',
  'port' => 6379,
    ),

Remember, this tutorial is only for a basic setup of Nextcloud on CentOS 7, with PHP 7.2. If you are going to use more features like LDAP or Single Sign On, you will need additional PHP modules as well as extra configurations. So please visit the rest of the Admin manual, Introduction, for detailed descriptions on how to get this done.
