Zabbix正常启动服务，但是netstat没有端口

netstat -lntp看不到zabbix的10050，10051端口

看日志/var/log/zabbix/zabbix_server.log

[root@neo zabbix]# tail -n 50 zabbix_server.log #tail -n 50 test.log 查询日志尾部最后50行的日志;

2876:20220502:134720.684 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

解决：

[root@neo ~]# find / -name mysql.sock
/tmp/mysql.sock

vim /etc/zabbix/zabbix_server.conf

#修改一下DBSocket就行

DBSocket=/tmp/mysql.sock

systemctl restart zabbix-server

[root@neo zabbix]# netstat -lntup
