一，安装dsh
wget http://www.netfort.gr.jp/~dancer/software/downloads/libdshconfig-0.20.9.tar.gz
tar zxvf libdshconfig-0.20.9.tar.gz
cd libdshconfig-0.20.9
./configure
make && make install
wget http://www.netfort.gr.jp/~dancer/software/downloads/dsh-0.25.9.tar.gz
tar zxvf dsh-0.25.9.tar.gz
cd dsh-0.25.9
./configure
make && make install
ln -s /usr/local/lib/libdshconfig.so.1 /lib64/
wget http://www.netfort.gr.jp/~dancer/software/downloads/libdshconfig-0.20.9.tar.gz
tar zxvf libdshconfig-0.20.9.tar.gz
cd libdshconfig-0.20.9
./configure
make && make install
wget http://www.netfort.gr.jp/~dancer/software/downloads/dsh-0.25.9.tar.gz
tar zxvf dsh-0.25.9.tar.gz
cd dsh-0.25.9
./configure
make && make install
ln -s /usr/local/lib/libdshconfig.so.1 /lib64/
二，用法介绍：
[root@china-channel ~]# dsh –help

三，创建控制的主机列表
[root@rong2 .dsh]# cat machines.list
192.168.0.2
四：配置ssh无密码登陆
在/root/.ssh目录下生成id_rsa，id_rsa.pub
把id_rsa.pub拷贝到被控制机的/root/.ssh/目录下：
[root@mail176 .ssh]#mv id_rsa.pub authorized_keys
[root@mail176 .ssh]#chmod 600 authorized_keys
对于有多个不同控制机的，可以通过cat id_rsa.pub >>authorized_keys 追加的形式
把id_rsa.pub拷贝到被控制机的/root/.ssh/目录下：
[root@mail176 .ssh]#mv id_rsa.pub authorized_keys
[root@mail176 .ssh]#chmod 600 authorized_keys
对于有多个不同控制机的，可以通过cat id_rsa.pub >>authorized_keys 追加的形式
五，应用举例：
[root@rong2 .dsh]# dsh -H -r ssh -a -- ifconfig eth0
