今天下午自己寫了個臨時的綜合腳本，實現(xiàn)了幾個功能：1根據(jù)PID查看該進程的相關(guān)信息；
2檢查CPU的使用率；3 ssh連接某臺主機；4 zabbix安裝前的幾個必要條件，即LNMP或LAMP的安裝；5 數(shù)據(jù)庫備份這個功能暫時沒有實現(xiàn)；
trippal原創(chuàng)文章，請勿轉(zhuǎn)載！
執(zhí)行結(jié)果如下所示
1 pidsearch
如果該進程不存在，還是會繼續(xù)跳過這次尋找
2 checkcpu
按ctrl+c可以退出該dstat命令
3 ssh連接
4 zabbix-install-test 這個因為我這臺mysql服務(wù)器暫時不想要安裝nginx和Apache，php這四個服務(wù)，所以該shell里的四個安裝這些服務(wù)的函數(shù)暫時被我注釋掉了，所以只有下面只有檢測的結(jié)果
5 db-backup 這個功能暫時沒法實現(xiàn)，估計冷備某個數(shù)據(jù)庫也是需要些時間來寫，所以這個地方暫時只有一條echo 打印語句
最后 想退出可以輸入 exit 終止該shell腳本
最后貼上我寫的腳本
