安裝clustershell

從https://github.com/cea-hpc/clustershell/downloads下面源碼或者二進位包進行安裝。

下面以CentOS6.6使用rpm安裝為例：

wget https://github.com/downloads/cea-hpc/clustershell/clustershell-1.5.1-1.el6.noarch.rpm

rpm -ivh clustershell-1.5.1-1.el6.noarch.rpm

 

源碼安裝方式：

wget https://github.com/downloads/cea-hpc/clustershell/clustershell-1.5.1.tar.gz

tar -xvf clustershell-1.5.1.tar.gz

cd clustershell-1.5.1

sudo python setup.py install

mkdir /etc/clustershell

cp conf/* /etc/clustershell

 

使用clustershell

首先，對於我們要管理的節點，建立一個組。假如我們需要管理的是10台web server，主機名稱分別為web1-web10，那麼我們先建立一個檔案/etc/clustershell/groups，內容如下：

web: web1 web2 web3 web4 web5 web6 web7 web8 web9 web10

其中：web是組名，web1-10是組下面的所有主機名稱。

 

接下來就可以使用clustershell批量執行命令了：

clush --user=root -g web "uptime"  ### --user指明了ssh登入的使用者；-g指明了組名；最後是批量執行的命令，將會在組下面所有節點執行該命令。
