記一次zabbix-server服務啟動失敗處理過程（Zabbix 3.0.9）
注意PID相關的是否是與selinux相關的
在CentOS7x64 7.3.1611上測試部署Zabbix 3.0.9，到啟動zabbix-server服務時報錯：
[[email protected] ~]#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.
按提示執行了systemctl status zabbix-server.service和journalctl -xe:
[[email protected] ~]# 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

看日誌應該是Zabbix資料庫配置不完整，zabbix.users表沒有建立，即Zabbix資料庫配置時建庫建表等動作沒有按照要求正常完成。
補充了相關操作後再試，zabbix-server服務啟動正常了：
Zabbix管理頁面能正常登陸並開啟：
