安装mysql
	$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
	$ sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
	$ sudo yum install mysql-server
	$ mysql -u root
登录时有可能报这样的错：ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)，原因是/var/lib/mysql的访问权限问题。下面的命令把/var/lib/mysql的拥有者改为当前用户：
	$ sudo chown -R root:root /var/lib/mysql
重启mysql服务
	$ service mysqld restart
	$ mysql -u root  //直接回车进入mysql控制台
	mysql > use mysql;
	mysql > update user set password=password('123456') where user='root';
	mysql > create database opencart;
	mysql > exit;

安装php扩展
	yum -y install php-gd
	yum -y install php-mysqlnd
