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。
具体下载目录在 /2012年资料/6月/12日/批量部署ssh私钥认证以及pssh工具使用方法/
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
