用Fabric自动推送nagios client脚本

qq524061227

　　线上的Nagios Client端的监控脚本因为业务需求又发生改动了，某业务集群差不多就有23台（下面的list只列出了8台），而且其中的一个业务需求脚本前前后后改动了4次，如果手动操作的话会累死人，幸亏有Fabric这个轻量级的自动化运维工具，代码如下：
#!/usr/bin/python2.6
from fabric.api import *
from fabric.colors import *
from fabric.context_managers import *
user = 'ec2-user'
hosts = ['bidder1','bidder2','bidder3','bidder4','bidder5','bidder6','bidder7','bidder8']
# hosts = ['bidder1',]
@task
def put_task():
    print yellow("Put Local File to remote")
    with settings(warn_only=True):
        put("/home/ec2-user/check_cpu_utili.sh","/home/ec2-user/check_cpu_utili.sh")
        sudo("cp /home/ec2-user/check_cpu_utili.sh /usr/local/nagios/libexec")
        sudo("chown nagios:nagios /usr/local/nagios/libexec/check_cpu_utili.sh")
        sudo("chmod +x /usr/local/nagios/libexec/check_cpu_utili")
        sudo("kill -9 `ps aux | grep nrpe | head -n1 | awk '{print $2}' `")
        sudo("/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d")
        print green("Put File success and restart nagios nrpe service!")
for host in hosts:
    env.host_string = host
    put_task()
#put_task()
