Initial setup

Install CentOS 7 with default Minimal configuration then install all current updates:

yum -y update

Next, we need to install PHP, Apache web server and MySQL server and some php extensions:

yum install httpd php php-mysql mariadb-server mariadb sqlite php-dom php-mbstring php-gd php-pdo 

Set SELinux to allow OwnCloud to write the data:

setsebool -P httpd_unified 1

Allow web traffic through the firewall:

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

Start Apache using the following command:

systemctl start httpd.service

Start  MariaDBby issuing this command:

systemctl start mariadb.service

systemctl enable httpd.service
systemctl enable mariadb.service

Installation

First, we need to download ownCloud from official website. Run the following command.

wget https://download.owncloud.org/community/owncloud-9.0.0.tar.bz2

Extract the archive we just downloaded.

tar -jxvf owncloud-7.0.0.tar.bz2 -C /var/www/html/

Next we need to assign the permission for web server to read and write the files on cloud directory.

chown -R apache.apache /var/www/html/owncloud/

DataBase configuration

Configure the mariadb instance.

mysql_secure_installation;

Hit enter on any of these that have the capital Y .

Set root password?[Y/n]New password: databaserootpassword Re-enter new password: databaserootpassword 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]

Create the ownCloud database and user.

Login to mysql server, Using the following command

mysql -u root -p

Next, we need to Create DataBase for ownCloud and grand permission for ownCloud user.

mysql> create database owncloud; mysql> create user 'owncloud'@'LOCALHOST' identified by'YOUR-DATABASE-PASSWORD'; mysql> grant all on owncloud.* to 'owncloud'@'LOCALHOST'; mysql> flush privileges; mysql> quit;

Apache server configuration

Open an external configuration file for ownCloud in your favorite editor, I’m using vim.

vim /etc/httpd/conf.d/owncloud.conf

Add the following lines in the config file.

<IfModule mod_alias.c> Alias /owncloud /var/www/html/owncloud </IfModule> <Directory “/var/www/html/owncloud”> Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
allow from all </Directory>

如果要检查apache有没有安装，可以用命令检查apache的安装包是否安装上。

# rpm -qa | grep httpd

如果想看安装的运行级别。

# chkconfig --list httpd

如果想看有没有启动。

# service httpd status

etc/httpd是apache的安装目录，

如果发现有.htaccess设置不正确的提示，可以这样：

打开httpd.conf(在那里? APACHE目录的CONF目录里面),用vim打开后,查找

Options FollowSymLinks

AllowOverride None

改为

Options FollowSymLinks

AllowOverride All

然后去掉下面的注释

LoadModule rewrite_module modules/mod_rewrite.so

.htaccess可以更改上传文件大小，默认的是2M

上传大小限制(设置成10G)

编辑文件：/var/www/html/owncloud/.htaccess

    php_value upload_max_filesize 10240M

    php_value post_max_size 10240M

    php_value memory_limit 2048M

Restart all apache and mariaDB services:

systemctl start httpd.service
systemctl start mariadb.service

OwnCloud configuration

Open up your favorite browser and paste http://your_ip_address/owncloud or http://your_Domain.com/owncloud . It will shows the initial owncloud setup page. it must be configured before going to live.
