首先 先安装nginx
echo '[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1' >>/etc/yum.repos.d/nginx.repo
yum install nginx -y
第二 测试python 监控nginx 进程
mkdir -p /usr/local/nignx/logs
touch /usr/local/nignx/logs/nginx.lock
[root@c ~]# cat chkng
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import os
pf ="/usr/local/nignx/logs/nginx.lock"
os.system("ps -A|grep nginx>%s"% pf)
if not(os.path.getsize(pf)):
os.system("/etc/init.d/nginx restart")
[root@c ~]# chmod +x chkng
[root@c ~]#crontab -l
*/5 * * * * /root/chkng
[root@c ~]# /etc/init.d/nginx stop
停止 nginx： [确定]
[root@c ~]# netstat -nlpt
