安装clustershell

https://github.com/cea-hpc/clustershell/downloads下面源码或者二进制包进行安装。

下面以CentOS6.6使用rpm安装为例:

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

 

源码安装方式:

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,对于我们要管理的节点,创建一个组。假如我们需要管理的是10台web server,主机名分别为web1-web10,那么我们先创建一个文件/etc/clustershell/groups,内容如下:

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

其中:web是组名,web1-10是组下面的所有主机名。

 

接下来就可以使用clustershell批量执行命令了:

clush --user=root -g web "uptime"  ### --user指明了ssh登录的用户;-g指明了组名;最后是批量执行的命令,将会在组下面所有节点执行该命令。
