我的运维状态 二

可能更好的方法是用Git服务器进行发布。

代码解释：

定义角色组、密码、以及fab方法。再对方法进行单独角色赋值。并且用并发模式来执行。

Code:

from fabric.api import *
env.roledefs ={
        "git-server" : ["[email protected]"],
        "ktmgame" : ["[email protected]"],
        "lvs" : ["[email protected]"],
        "web" : ["[email protected]","[email protected]"]
}
env.password = '********'
@roles("web","lvs")
@parallel(pool_size=5)
def df():
    run("df -h")
@roles("lvs")
def LvsStart():
    put("lvs","/etc/rc.d/init.d/lvs")
    run("chmod 755 /etc/rc.d/init.d/lvs;service lvs start")
@roles("lvs")
def LvsRestart():
    run("chmod 755 /etc/rc.d/init.d/lvs;service lvs stop;service lvs start")
@roles("web")
def LvsWebStart():
    put("lvsR","/etc/rc.d/init.d/lvsR")
    run("chmod 755 /etc/rc.d/init.d/lvsR;service lvsR start")

Output:
