ZABBIX启动时报： “/tmp/zabbix_server_alerter.sock“ is used by another“/tmp/zabbix_server_alerter.sock“

我遇到的问题：
启动zabbix服务端，启动报错：

cannot start preprocessing service: The file "/tmp/zabbix_server_preprocessing.sock" is used by another
  4370:20210113:143247.721 server #49 started [alert manager #1]

zabbix_server [4287]: Error waiting for process with PID 4371: [10] No child processes

解决方法：
删除报错文件

rm -rf /tmp/zabbix_server_preprocessing.sock
rm -rf /tmp/zabbix_server_alerter.sock

重新启动服务解决，解决仅供参考，其他不负责
