dsh 批量管理伺服器

一，安裝dsh

wget http://www.netfort.gr.jp/~dancer/software/downloads/libdshconfig-0.20.9.tar.gz

tar xvf libdshconfig-0.20.9.tar.gz

cd libdshconfig-0.20.9

./configure --prefix=/usr/

make && make install

wget http://www.netfort.gr.jp/~dancer/software/downloads/dsh-0.25.9.tar.gz

tar xvf dsh-0.25.9.tar.gz

cd dsh-0.25.9

ldconfig

[root@heit]# dsh --help

這說明安裝成功

ssh-keygen -t rsa

一路回車會在/root/.ssh/目錄下生成公鑰（id_rsa.pub）和私鑰（id_rsa）。

将id_rsa.pub複制到被控制端/root/.ssh/目錄下

mv id_rsa.pub authorized_keys

chmod authorized_keys 600

在控制端

mkdir /root/.dsh/

mkdir /root/.dsh/group/

touch /root/.dsh/machines.list

touch /root/.dsh/group/g1

cat //root/.dsh/machines.list

192.168.220.12

cat /root/.dsh/group/g1

dsh -r ssh -a touch /root/a

dsh -r ssh -g g1 touch /root/a
