Owncloud Centos7

How to Install ownCloud 9 on CentOS 7

http://www.systeen.com/2016/05/16/install-owncloud-9-centos-7/

ownCloud is an open source free cloud software that allows you to have a personal synching service. It is similar to the Dropbox cloud storage but operates on your own server. The software has been in the market for years now and has proven its robustness by all means. It is quick, secure, and easy to setup.
In this tutorial we are going to install the latest up to date version of ownCloud 9 (v9.0.2) on CentOS 7.  ownCloud requires the below softwares to run:

• MySQL/MariaDB
• PHP 5.4 +
• Apache 2.4 with mod_php

We will choose to install MariaDB, PHP 5.5, and Apache 2.4

Install MariaDB 5.5

Run the below command to install MariaDB server and client. We will use MariaDB to connect ownCloud to its own MySQL database.

yum install mariadb-server mariadb

1	yum install mariadb-server mariadb

Start the MariaDB server:

systemctl start mariadb

1	systemctl start mariadb

Allow MariaDB to start during machine boot:

systemctl enable mariadb

1	systemctl enable mariadb

Configure MySQL to ensure it is secured and running:

mysql_secure_installation

1	mysql_secure_installation

Install Apache 2.4

ownCloud 9 has a friendly web interface. This requires the installation of Apache. Run the below command to install Apache 2.4.6

yum install httpd

1	yum install httpd

Start the Apache service

systemctl start httpd

1	systemctl start httpd

Add Apache to allow it to start during boot time:

systemctl enable httpd

1	systemctl enable httpd

To test if Apache is running fine, browse to your machine IP : http://your-machine-ip/
You should see the below Apache test page:

Install PHP 5.5

If you run “yum install php” you will be installing PHP v5.4. Unfortunately, this version is not supported anymore and has reached EOL. That is why ownCloud recommends installing PHP 5.5+ .
The first step is to install the SCL repository:

yum install centos-release-scl

1	yum install centos-release-scl

Then install PHP 5.5 and these modules:

yum install php55 php55-php php55-php-gd php55-php-mbstring php55-php-mysqlnd

1	yum install php55 php55-php php55-php-gd php55-php-mbstring php55-php-mysqlnd

Copy the PHP 5.5 Apache modules into place:

cp /opt/rh/httpd24/root/etc/httpd/conf.d/php55-php.conf /etc/httpd/conf.d/ cp /opt/rh/httpd24/root/etc/httpd/conf.modules.d/10-php55-php.conf /etc/httpd/conf.modules.d/ cp /opt/rh/httpd24/root/etc/httpd/modules/libphp55-php5.so /etc/httpd/modules/

1 2 3 4 5

cp /opt/rh/httpd24/root/etc/httpd/conf.d/php55-php.conf /etc/httpd/conf.d/   cp /opt/rh/httpd24/root/etc/httpd/conf.modules.d/10-php55-php.conf /etc/httpd/conf.modules.d/   cp /opt/rh/httpd24/root/etc/httpd/modules/libphp55-php5.so /etc/httpd/modules/

Then restart Apache:

systemctl restart httpd

1	systemctl restart httpd

Verify with phpinfo that your Apache server is using PHP 5.5 and loading the correct modules. Create a new file in the httpd directory:

vi /var/www/html/info.php

1	vi /var/www/html/info.php

<?php phpinfo(); ?>

1 2 3

<?php phpinfo(); ?>

Now we call that file in a browser http://your-machine-ip/info.php . You should get the below:

Install ownCloud 9 (v9.0.2)

Run the following shell commands as root to trust the repository:

rpm --import https://download.owncloud.org/download/repositories/9.0/CentOS_7/repodata/repomd.xml.key

1	rpm --import https://download.owncloud.org/download/repositories/9.0/CentOS_7/repodata/repomd.xml.key

Run the following shell commands as root to add the repository and install from there.

wget http://download.owncloud.org/download/repositories/9.0/CentOS_7/ce:9.0.repo -O /etc/yum.repos.d/ce:9.0.repo

1	wget http://download.owncloud.org/download/repositories/9.0/CentOS_7/ce:9.0.repo -O /etc/yum.repos.d/ce:9.0.repo

Clean expired cache to ensure you install the latest ownCloud files:

yum clean expire-cache

1	yum clean expire-cache

Install ownCloud:

yum install owncloud-files

1	yum install owncloud-files

Once done with the installation, browse to http://your-server-ip/owncloud . You should get the following page.

However, there are some directory permissions that need to be fixed in order to continue with the ownCloud 9 installation wizard.

Fix Permissons

ownCloud has created a bash script that fixes those permissions. Create a new file in the /tmp directory and give it execute permissions.

vi /tmp/dirperm.sh

1	vi /tmp/dirperm.sh

Add the below to the file we created:

#!/bin/bash ocpath='/var/www/html/owncloud' htuser='apache' htgroup='apache' rootuser='root' printf "Creating possible missing Directories\n" mkdir -p $ocpath/data mkdir -p $ocpath/assets mkdir -p $ocpath/updater printf "chmod Files and Directories\n" find ${ocpath}/ -type f -print0 | xargs -0 chmod 0640 find ${ocpath}/ -type d -print0 | xargs -0 chmod 0750 printf "chown Directories\n" chown -R ${rootuser}:${htgroup} ${ocpath}/ chown -R ${htuser}:${htgroup} ${ocpath}/apps/ chown -R ${htuser}:${htgroup} ${ocpath}/assets/ chown -R ${htuser}:${htgroup} ${ocpath}/config/ chown -R ${htuser}:${htgroup} ${ocpath}/data/ chown -R ${htuser}:${htgroup} ${ocpath}/themes/ chown -R ${htuser}:${htgroup} ${ocpath}/updater/ chmod +x ${ocpath}/occ printf "chmod/chown .htaccess\n" if [ -f ${ocpath}/.htaccess ] then chmod 0644 ${ocpath}/.htaccess chown ${rootuser}:${htgroup} ${ocpath}/.htaccess fi if [ -f ${ocpath}/data/.htaccess ] then chmod 0644 ${ocpath}/data/.htaccess chown ${rootuser}:${htgroup} ${ocpath}/data/.htaccess fi

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

#!/bin/bash ocpath='/var/www/html/owncloud' htuser='apache' htgroup='apache' rootuser='root'   printf "Creating possible missing Directories\n" mkdir -p $ocpath/data mkdir -p $ocpath/assets mkdir -p $ocpath/updater   printf "chmod Files and Directories\n" find ${ocpath}/ -type f -print0 | xargs -0 chmod 0640 find ${ocpath}/ -type d -print0 | xargs -0 chmod 0750   printf "chown Directories\n" chown -R ${rootuser}:${htgroup} ${ocpath}/ chown -R ${htuser}:${htgroup} ${ocpath}/apps/ chown -R ${htuser}:${htgroup} ${ocpath}/assets/ chown -R ${htuser}:${htgroup} ${ocpath}/config/ chown -R ${htuser}:${htgroup} ${ocpath}/data/ chown -R ${htuser}:${htgroup} ${ocpath}/themes/ chown -R ${htuser}:${htgroup} ${ocpath}/updater/   chmod +x ${ocpath}/occ   printf "chmod/chown .htaccess\n" if [ -f ${ocpath}/.htaccess ] then chmod 0644 ${ocpath}/.htaccess chown ${rootuser}:${htgroup} ${ocpath}/.htaccess fi if [ -f ${ocpath}/data/.htaccess ] then chmod 0644 ${ocpath}/data/.htaccess chown ${rootuser}:${htgroup} ${ocpath}/data/.htaccess fi

Allow execute permissions to the file we created:

chmod 755 /tmp/dirperm.sh

1	chmod 755 /tmp/dirperm.sh

Output:

/tmp/dirperm.sh Creating possible missing Directories chmod Files and Directories chown Directories chmod/chown .htaccess

1 2 3 4 5 6

/tmp/dirperm.sh   Creating possible missing Directories chmod Files and Directories chown Directories chmod/chown .htaccess

When you have SELinux enabled on your Linux distribution, you may run into permissions problems after a new ownCloud installation, and see permission denied errors in your ownCloud logs. Run these commands as root:

semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/data' restorecon '/var/www/html/owncloud/data' semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/config' restorecon '/var/www/html/owncloud/config' semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/apps' restorecon '/var/www/html/owncloud/apps'

1 2 3 4 5 6 7 8 9 10 11

semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/data'   restorecon '/var/www/html/owncloud/data'   semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/config'   restorecon '/var/www/html/owncloud/config'   semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/apps'   restorecon '/var/www/html/owncloud/apps'

Refresh the page and you should get the following:

Configure Database

To continue with the installation wizard, we need to create a database for ownCloud and a user to access this database:

mysql -u root -p Enter password:

1 2	mysql -u root -p Enter password:

Run the below commands in order:

CREATE DATABASE owncloudDB; GRANT ALL ON owncloudDB.* to 'ownclouduser'@'localhost' IDENTIFIED BY 'ENTER_PASSWORD'; FLUSH PRIVILEGES; quit

1 2 3 4 5 6 7

CREATE DATABASE owncloudDB;   GRANT ALL ON owncloudDB.* to 'ownclouduser'@'localhost' IDENTIFIED BY 'ENTER_PASSWORD';   FLUSH PRIVILEGES;   quit

Choose MySQL as database and fill in the information needed and create a new admin user:


After finalizing the installation wizard, you will have a new ownCloud 9 installation ready to store data!
