[root~]# vi include/config.php #更改cacti配置文件
$database_username = "cacti"; #配置数据库用户名
$database_password = "test"; #配置数据库密码date_default_timezone_set('Asia/shanghai'); #添加cacti时间
[root~]# useradd cacti -d /usr/local/cacti/ #添加用户并对/cacti目录控制(会提示出错，忽略)
[root~]# chown -R cacti /usr/local/cacti/ #改变拥有者为cacti

MariaDB >FLUSH privileges; #刷新mysql
MariaDB >quit; #退出
[root~]# mysql -u cacti -p cacti < /usr/local/cacti/cacti.sql #导入库(输入test密码后，成功不会有任何提示直接返回命令行)
