1、先決條件：
安裝pssh工具的主機針對遠程主機需要配置免秘鑰認證：
ssh-keygen -t rsa
ssh-copy-id [remotehost]

2、下載mussh工具安裝介質：
https://jaist.dl.sourceforge.net/project/mussh/mussh/1.0/mussh-1.0.tgz

3、安裝mussh

mussh安裝非常簡單，直接解壓縮安裝包即可使用。

tar -zxvf mussh-1.0.tgz -C /usr/local/

執行/usr/local/mussh/mussh --help可以查看mussh命令幫助。

4、mussh使用案例

/usr/local/mussh/mussh -h db01 db02 -c uptime

$ cat machines
db01
db02
db03
db04
$ /usr/local/mussh/mussh -H machines -c uptime
