pssh 使用記錄

1、pssh 安裝

yum?-y?install?epel-release
yum?-y?install?pssh

安裝完畢后有一下命令：
pssh???????ssh執行命令
pscp.pssh??copy到遠程
pslurp?????pull從遠程
pnuke??????kill遠程進程
prsync?????同步

2、ssh 免密配置

?yum?-y?install?expect
?ssh-keygen??-t?rsa?-f?~/.ssh/id_rsa?-N?""?-q
?
?cat?<<?EEE??>>/tmp/sshkey.sh?

for?ip?in?{192.168.56.13,192.168.56.14,192.168.56.15,192.168.56.16}
do
expect?<<?EOF
????????spawn?ssh-copy-id?-i?/root/.ssh/id_rsa.pub?root@$ip
????????expect?{
????????????????"yes/no"?{?send?"yes\n";exp_continue}
????????????????"password"?{?send?"123456\n"}
????????}
????????expect?eof
EOF
done

EEE

/*那是一個描述符，告訴?shell?，管道符操作遇到這個東西就停下來。
EOF?只是一個通用的稱呼，其實換成別的也是可以的。這看你文件里面的具體要求。*/

3、我常用的方式

3.1、遠程yum 軟件

?pssh?-p?4??-h?ip.txt??-i???"yum?-y?install?screen"

3.2、遠程kill 進程

pssh?-p?2??-h?ip.txt??-i???"sudo?pkill?-9?top"

3.3、拷貝文件到遠程服務器

?pscp.pssh?-h?ip.txt?ip.txt?/tmp/ip.tmp

3.4、拉遠程文件

[root@mgr?~]#?pslurp?-h?ip.txt?/tmp/ip.tmp??/rip.txt
[1]?11:53:38?[SUCCESS]?192.168.56.15
[2]?11:53:38?[SUCCESS]?192.168.56.14
[3]?11:53:38?[SUCCESS]?192.168.56.13
[4]?11:53:38?[SUCCESS]?192.168.56.16
[root@mgr?~]#?ls?192.168.56.1*/
192.168.56.13/:
rip.txt

192.168.56.14/:
rip.txt

192.168.56.15/:

192.168.56.16/:

[root@mgr?~]#
