一、准备环境
机器：centos6.9
1、安装ansible
[root@localhost ~]# yum -y install ansible Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.btte.net * epel: mirrors.tuna.tsinghua.edu.cn * extras: mirrors.btte.net * updates: mirrors.tuna.tsinghua.edu.cn Package ansible-2.3.1.0-1.el6.noarch already installed and latest version Nothing to do
本机已经安装完ansible
2、批量配置免登录。
#!/usr/bin/expect
for p in $(cat /data/shell/list)
do
password=$(echo "$p"|cut -f1 -d":")
ip=$(echo "$p"|cut -f2 -d":")
expect -c "
spawn ssh-copy-id -i root@$ip
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
"
done
需要一个list文件，里面记录了需要更新的主机以及对应密码，格式如下：
123456:192.168.1.20 345676:192.168.2.20
密码：主机名 ，以分号分隔。
expect命令如果没有的话,需要提前安装
运行脚本后，显示如下：
[root@localhost shell]# sh expect.sh spawn ssh-copy-id -i root@192.168.6.189 spawn ssh-copy-id -i root@192.168.6.89 The authenticity of host '192.168.6.89 (192.168.6.89)' can't be established. RSA key fingerprint is 04:46:a5:a6:93:74:e1:d2:58:a1:3d:65:63:43:72:d8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.6.89' (RSA) to the list of known hosts. root@192.168.6.89's password: Now try logging into the machine, with "ssh 'root@192.168.6.89'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. spawn ssh-copy-id -i root@10.18.99.62 The authenticity of host '10.18.99.62 (10.18.99.62)' can't be established. RSA key fingerprint is 04:46:a5:a6:93:74:e1:d2:58:a1:3d:65:63:43:72:d8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.18.99.62' (RSA) to the list of known hosts. root@10.18.99.62's password: Now try logging into the machine, with "ssh 'root@10.18.99.62'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.
配置完毕。
二、配置ansible
1、编辑配置文件、添加用户组。
编辑 /etc/ansible/hosts
[all]
192.168.1.2
192.168.1.3
192.168.1.4
192.168.1.5
192.168.1.6
192.168.1.7
192.168.1.8
192.168.1.9
192.168.1.10
192.168.1.11
2、执行简单命令。
ansible all -m shell -a 'uptime'
192.168.1.3 | SUCCESS | rc=0 >>
14:08:24 up 1 day, 22:26, 1 user, load average: 0.06, 0.12, 0.13
192.168.1.2 | SUCCESS | rc=0 >>
14:10:02 up 3 days, 3:36, 2 users, load average: 0.04, 0.04, 0.05
3、成功执行命令并返回。
