netstat -lntp看不到zabbix的10050，10051端口

看日志/var/log/zabbix/zabbix_xxxx.log

  1184:20170701:005035.185 database is down: reconnecting in 10 seconds

  1184:20170701:005045.185 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

解决：

find / -name mysql.sock

vim /etc/zabbix/zabbix_server.conf 

#修改一下DBSocket就行

DBSocket=/tmp/mysql.sock

systemctl restart zabbix-server
