标题: zabbix connection to database 'zabbix' failed
在启动zabbix时启动失败，查看日志：
  1. [root@localhost zabbix]# tailf /tmp/zabbix_server.log  
  2. 24661:20180326:203250.916 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

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：
  1. [root@localhost zabbix]# find / -name mysql.sock  
  2. /tmp/mysql.sock  
复制代码
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
  1. [root@localhost lib]# mkdir /var/lib/mysql  
  2. [root@localhost lib]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock  
  3. [root@localhost lib]# /etc/rc.d/init.d/mysqld restart  
  4. Shutting down MySQL... SUCCESS!   
  5. Starting MySQL SUCCESS!   
复制代码
2)修改zabbix_server.conf中的mysql.sock的配置
  1. vim /etc/zabbix/zabbix_server.conf  
  2. DBSocket=/tmp/mysql.sock
复制代码
再重启zabbix就好
