假如同时给上千台服务器执行一个命令,拷贝一个文件,杀一个进程等,有什么简化运维管理的工具呢?在小型使用中我都是使用for循环,数量巨大,一方面不确定操作是否成功,一方面for循环语句性能不好估计且是不是同步并行执行.，这类工具比如 pdsh，mussh，cssh，dsh等还有这里提到的pssh:

2 pscp 把文件并行地复制到多个主机上
注意 是从服务器端给客户端传送文件:
注意 是从服务器端给客户端传送文件:
[root
@server pssh-2.2.2
]
# pscp -h test.txt /etc/sysconfig/network /tmp/network //标示将本地的/etc/sysconfig/network传到目标服务器的/tmp/network
3 prsync 使用rsync协议从本地计算机同步到远程主机
[root
@server ~
]
# pssh -h test.txt -P mkdir /tmp/etc
[root @server ~ ] # prsync -h test.txt -l dongwm -a -r /etc/sysconfig /tmp/etc //标示将本地的/etc/sysconfig目录递归同步到目标服务器的 /tmp/etc目录下,并保持原来的时间戳,使用用户 dongwm
[root @server ~ ] # prsync -h test.txt -l dongwm -a -r /etc/sysconfig /tmp/etc //标示将本地的/etc/sysconfig目录递归同步到目标服务器的 /tmp/etc目录下,并保持原来的时间戳,使用用户 dongwm
4 pslurp 将文件从远程主机复制到本地,和pscp方向相反:
[root
@server ~
]
# pslurp -h test.txt -L /tmp/test -l root /tmp/network test //标示将目标服务器的/tmp/network文件复制到本地的/tmp/test目录下,并更名为test

5 pnuke 并行在远程主机杀进程:
[root
@server ~
]
# pnuke -h test.txt syslog //杀死目标服务器的syslog进程,只要ps进程中出现相关词语 都能杀死
