不得不說，腳本在我們的日常工作中可以提高很大的工作效率，的確很香！

這次再來給大家分享一波我工作中用到的幾個腳本，主要分為：Python和Shell兩個部分。

Python 腳本部分實例：企業微信告警、FTP 客戶端、SSH 客戶端、Saltstack 客戶端、vCenter 客戶端、獲取域名 ssl 證書過期時間、發送今天的天氣預報以及未來的天氣趨勢圖；

Shell 腳本部分實例：SVN 完整備份、Zabbix 監控用戶密碼過期、構建本地 YUM 以及上篇文章中有讀者的需求（負載高時，查出占用比較高的進程腳本并存儲或推送通知）；

篇幅有些長，還請大家耐心翻到文末，畢竟有彩蛋。

Python?腳本部分

企業微信告警

此腳本通過企業微信應用，進行微信告警，可用于 Zabbix 監控。

構建本地YUM

通過 rsync 的方式同步 yum，通過 nginx 只做 http yum 站點；

但是 centos6 的鏡像最近都不能用了，國內貌似都禁用了，如果找到合適的自行更換地址。

讀者需求解答

負載高時，查出占用比較高的進程腳本并存儲或推送通知

這部分內容是上篇 Shell 腳本實例中底部讀者留言的需求，如下：

以上，就是今天分享的全部內容了。

希望大家通過這些案例能夠學以致用，結合自身的實際場景進行運用，從而提高自己的工作效率。

如果你有更多腳本實例，也歡迎大家分享或通過本文留言區進行留言說說你具體的腳本實例需求，如果實例過多的話，下次杰哥在整一篇合集腳本文章實例來跟大家分享。
