记一次zabbix-server服务启动失败处理过程（Zabbix 3.0.9）

注意PID相关的是否是与selinux相关的

在CentOS7x64 7.3.1611上测试部署Zabbix 3.0.9，到启动zabbix-server服务时报错：

[root@CentOS7x64 ~]#systemctl restart zabbix-server

Job forzabbix-server.service failed because a configured resource limit was exceeded.See "systemctl status zabbix-server.service" and "journalctl-xe" for details.

按提示执行了systemctl status zabbix-server.service和journalctl -xe:
[root@CentOS7x64 ~]# journalctl -xe

                                           #ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver

                                           #semodule -i my-zabbixserver.pp

                                          *****  Plugin catchall (100.confidence) suggests  **************************

                                          

                                           Ifyou believe that zabbix_server should be allowed setrlimit access on processeslabeled zabbix_t by default.

                                           Thenyou should report this as a bug.

                                           Youcan generate a local policy module to allow this access.

                                           Do

                                          allow this access for now by executing:

                                           #ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver

                                           #semodule -i my-zabbixserver.pp

看日志应该是Zabbix数据库配置不完整，zabbix.users表没有创建，即Zabbix数据库配置时建库建表等动作没有按照要求正常完成。

补充了相关操作后再试，zabbix-server服务启动正常了：

Zabbix管理页面能正常登陆并打开：
