登陆mysql数据库报错

[root@ZabbixServer mysql]# /usr/local/mysql/bin/mysql -p -uroot -S /tmp/mysql.sock
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

• 原因分析:

  1.查看mysql目录权限，发现mysql目录的权限没有问题。

  [root@ZabbixServer local]# ls -ld /usr/local/mysql
  drwxr-xr-x. 13 mysql mysql 4096 11月 19 15:42 /usr/local/mysql

  2.查看配置文件my.cnf中socket的配置，发现配置文件中socket的配置不是/tmp/mysql.sock。

  [root@ZabbixServer local]# more /etc/my.cnf |grep sock
  socket=/var/lib/mysql/mysql.sock

• 解决办法：

  1. 修改配置文件中socket的配置为/tmp/mysql.sock。
     命令如下：

     [root@ZabbixServer local]# vi /etc/my.cnf #找到并修改socket=/tmp/mysql.sock
     [root@ZabbixServer local]# more /etc/my.cnf |grep sock
     socket = /tmp/mysql.sock

  2. 使用配置文件中socket的配置目录
     命令如下：

     [root@ZabbixServer local]# /usr/local/mysql/bin/mysql -p -uroot -S /var/lib/mysql/mysql.sock 
     Enter password:
