大螃嗨

从这里下载最新的安装包https://www.opencart.com

解压缩安装包，将upload文件夹移动到网页目录下。

设置如下路径的读写权限：

	chmod 0755 or 0777 system/storage/cache/
	chmod 0755 or 0777 system/storage/download/
	chmod 0755 or 0777 system/storage/logs/
	chmod 0755 or 0777 system/storage/modification/
	chmod 0755 or 0777 system/storage/session/
	chmod 0755 or 0777 system/storage/upload/
	chmod 0755 or 0777 system/storage/vendor/
	chmod 0755 or 0777 image/
	chmod 0755 or 0777 image/cache/
	chmod 0755 or 0777 image/catalog/
	chmod 0755 or 0777 config.php
	chmod 0755 or 0777 admin/config.php

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

浏览器打开网页，开始安装过程。
