批量部署ssh私钥认证以及pssh工具使用方法

在日常工作中,批量管理服务器是个力气活,如果人工一台一台处理,效率低下。此时,老外写的pssh工具实现了批量管理。

它的原理是先建立ssh私钥认证,然后用pssh工具批量管理。

下面,我写了一个批量部署ssh私钥认证的脚本。

batch_sshkey.sh
==============================================================

#!/bin/bash

cd /root

cat /root/.ssh/id_rsa.pub > /root/.ssh/authorized_keys

for i in `cat ip.txt`
do
ip=$(echo "$i"|cut -f1 -d":")
password=$(echo "$i"|cut -f2 -d":")
 

expect -c "
spawn scp /root/.ssh/authorized_keys /root/remote_operate.sh  root@$ip:/tmp/
        expect {
                \"*yes/no*\" {send \"yes\r\"; exp_continue}
                \"*password*\" {send \"$password\r\"; exp_continue}
                \"*Password*\" {send \"$password\r\";}
        }
"

expect -c "
spawn ssh root@$ip "/tmp/remote_operate.sh"
        expect {
                \"*yes/no*\" {send \"yes\r\"; exp_continue}
                \"*password*\" {send \"$password\r\"; exp_continue}
                \"*Password*\" {send \"$password\r\";}
        }
"

done

============================================================

ip.txt(前面是IP,后面是密码,用冒号:分割)

192.168.8.23:123456
192.168.8.24:456789

============================================================

remote_operate.sh

#!/bin/bash

if [ ! -d /root/.ssh ];then
mkdir /root/.ssh
fi
cp /tmp/authorized_keys /root/.ssh/

==========================================================

运行batch_sshkey.sh即可。

下面介绍PSSH工具使用方法,使用很简单:

# yum install *Python*

# tar  zxvf pssh-1.4.3.tar.gz

# cd pssh-1.4.3

# python setup.py install

# 批量执行hostname命令
# pssh -h other.txt -l root -i hostname
