zabbix更换ip地址后，报错Zabbix server is not running，解决如下：
找到zabbix.conf.php文件，默人安装如下；
# vim /etc/zabbix/web/zabbix.conf.php
# ZBX_SERVER = '**your zabbix ip address or DNS name**';
# ZBX_SERVER_PORT = '10051';
# ZBX_SERVER_NAME = '**your zabbix hostname**'; #你的ip地址
Just change the ip address you can resolve the error :（更换ip地址后，错误解决）
Zabbix server is not running: the information displayed may not be current
After that restart the zabbix server（重启zabbix server）
# service zabbix-server restart
To verify go to Dashboard Administration -> queue there you see data（在仪表板查看状态）
I resolved my error like this works fine for me.
