在启动zabbix时启动失败，查看日志：

[root@localhost zabbix]# tailf /tmp/zabbix_server.log

发现日志链接不上

[root@localhost zabbix]# ll /var/lib/mysql/mysql.sock
ls: cannot access /var/lib/mysql/mysql.sock: No such file or directory
[root@localhost zabbix]# ll /var/lib/mysql
ls: cannot access /var/lib/mysql: No such file or directory

可以知道是/var/lib/mysql/mysql.sock不存在

在系统中查找mysql.sock文件：

[root@localhost zabbix]# find / -name mysql.sock
find: ?.run/user/1000/gvfs?. Permission denied
/tmp/mysql.sock

可以知道是在/tmp/下，这个时候有两种方式解决这个问题：

1）做mysql.sock的链接

[root@localhost lib]# mkdir /var/lib/mysql
[root@localhost lib]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
[root@localhost lib]# /etc/rc.d/init.d/mysqld restart
Shutting down MySQL... SUCCESS! 
Starting MySQL SUCCESS!

2)修改zabbix_server.conf中的mysql.sock的配置

vim /etc/zabbix/zabbix_server.conf
DBSocket=/tmp/mysql.sock

再重启zabbix就好
