MySql安装后写命令提示 Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

从官方渠道下载了MySQL-server-5.5.37-1.linux2.6.x86_64.rpm
通过rpm -ivh命令安装,安装在安装目录下后写命令mysql -uroot
提示 Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

咋整啊

---

1. 查看mysql-server是否启动 ps aux | grep mysql
2. 如果没有启动，查看mysql错误日志，可以把日志贴出来，日志一般在/var/log下

我想大半是mysql-server没启动成功

配置文件中客户端和服务端使用的sock路径应该一致

问题解决.
