man obj roo services tor pid lsi init.d depend
最近安裝nagios時，檢查的的狀態都沒有什麽問題，就是監控系統的狀態顯示不出來
檢測的結果如下：

查看nagios日誌的內容：
[root@lb02 var]# tail nagios.log [1536369288] LOG VERSION: 2.0 [1536369288] Finished daemonizing...

錯誤原因：大致是我不能創建nagios.cmd，到/usr/local/nagios/var目錄下竟然發現沒有rw目錄，創建之後重新加載nagios
[root@lb02 var]# mkdir rw [root@lb02 var]# chown -R nagios.nagios rw [root@lb02 var]# ll total 40 drwxrwxr-x 2 nagios nagios 4096 Sep 6 12:55 archives -rw-r--r-- 1 nagios nagios 5 Sep 8 09:23 nagios.lock -rw-rw-r-- 1 nagios nagios 3991 Sep 8 09:23 nagios.log -rw-r--r-- 1 nagios nagios 17051 Sep 8 09:23 objects.cache -rw-rw-r-- 1 nagios nagios 0 Sep 8 09:23 retention.dat drwxr-xr-x 2 nagios nagios 4096 Sep 8 09:25 rw drwxr-xr-x 3 root root 4096 Sep 6 12:55 spool
此時才加載到正確的監控效果。
