ansible 入门测试

所有步骤均在ansible server主机上执行。

安装ansible

 wget -O  /etc/yum.repos.d/epel.repo   http://mirrors.aliyun.com/repo/epel-7.repo
 yum install ansible  -y

cansible 到workder节点免密登录

生成公钥

ssh-keygen -t  rsa

公钥拷贝到woker节点  *2 

ssh-copy-id [email protected]

或者用脚本

yum  install  expect  -y

#cat list

20.20.45.177
20.20.41.213

#cat copy_ssh_key.sh

#!/bin/bash
while read line
  do
    user="root"
    ip=`echo $line | cut -d " " -f 1`
    passwd="1"
    echo ip: $ip
    echo pw: $passwd
    expect <<EOF
      set timeout 2s
      spawn  ssh-copy-id -i /root/.ssh/id_rsa.pub $user@$ip
      expect {
         "yes/no"   { send  "yes\n"; exp_continue }
         "password" { send "$passwd\n" }
       }
       expect "password" { send "$passwd\n" }
EOF
  done < list   

设置inventory

cat /etc/ansible/hosts

[client01]

[client02]

测试，（不能在项目目录下测试）
