最近由于工作的需要寫(xiě)了個(gè)多線程批量ping服務(wù)器的腳本，如果服務(wù)器down了，自動(dòng)發(fā)報(bào)警郵件(可以添加多收件人)

?

提示：程序網(wǎng)頁(yè)顯示可以能有縮進(jìn)問(wèn)題。

multithreading_ping_host.py?主程序使用需要一個(gè)參數(shù)，(參數(shù)：服務(wù)器IP地址列表)

send_mail.py?發(fā)郵件程序

ip.yml?服務(wù)器IP地址列表

[root@nginx1?python]#?cat?/root/python/ip.yml?
192.168.1.1
192.168.1.103
192.168.1.100

192.168.1.245

[root@nginx1?python]#?./multithreading_ping_host.py?/root/python/ip.yml?

程序效果：
