安装
yum -y install ansible expect
生成key,ssh-keygen -t rsa -f ~/.ssh/id_rsa
两种办法
-
ssh+expect 出自oldbody
cat /etc/ansible/hosts
[web]
web1 ansible_ssh_host=192.168.1.21
web2 ansible_ssh_host=192.168.1.22
提供修改的exp.sh

使用方法：./exp.sh ip，就会自动建立ssh了，然后ansible各种命令测试
2.authorized_key模块
分两步走
1.known_host

2.编写简单的yml

# Example using key data from a local file on the management machine- authorized_key: user=charlie key="{{ lookup('file', '/home/charlie/.ssh/id_rsa.pub') }}" |
cat /etc/ansible/hosts
[unknow]
web3 ansible_ssh_user=root ansible_ssh_host=192.168.1.21 ansible_ssh_pass="你的密码"
简单的使用

cat rsync_key.ymal--- - hosts: web3 user: root tasks: - name: ssh authorized_key: user="root" key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}" |
使用方法：ansible-playbook rsync_key.ymal

authorized_key ymal格式不会写，Google到的

第一种方式：手动安装 cd ~/Downloads curl -O -L http://downloads.sourceforge.net/project/sshpass/sshpass/1.05/sshpass-1.05.tar.gz tar xvzf sshpass-1.05.tar.gz cd sshpass-1.05 ./configure make sudo make install
``` 第二种方式，安装Mac os包管理器之外第三方包 brew install https://raw.github.com/eugeneoden/homebrew/eca9de1/Library/Formula/sshpass.rb
3.配置文件
/etc/ansible/hosts — 默认资源文件 /usr/share/ansible/ — 默认模块库 /etc/ansible/ansible.cfg — 默认配置文件 ~/.ansible.cfg — 用户配置文件，如果使用优先级高于ansible.cfg配置文件
具体配置文件参考：http://docs.ansible.com/intro_configuration.html#pipelining
step2：远程执行命令
ansible是基于ssh协议之上进行远程管理，所以无须安装客户端，直接只要能ssh连接过去，就可以进行管理了
1.配置管理客户端和秘钥登录
cp hosts hosts.bak vim hosts [test] //group_name，名称可以自定义，可以将不同的作用的机器放在不同的组里 192.168.122.134 192.168.122.131 [test] 192.168.122.134 ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=skstserver #ssh无秘钥登录ssh-keygen -t rsa -P ''ssh-copy-id -i .ssh/id_rsa.pub root@192.168.122.131
2、批量发送公钥
为ansible开始管理节点传递公钥
如果是可以直接使用root的环境，则直接使用这个脚本
vim tra_pub.exp
#!/usr/bin/expect -f
set timeout -1
set user root
set passwd "123456"
for { set i 201 } { $i < 208 } { incr i } {
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub $user@192.168.1.$i
expect {
"yes/no" { send "yes\r";exp_continue }
"id_rsa" { send "yes\r";exp_continue }
"*assword" { send "$passwd\r" }
}
}
expect eof
如果需要使用普通用户进行切换的环境则可以使用以下的脚本
#!/usr/bin/expect -f
set timeout -1
set user test
set passwd "123456"
for { set i 100 } { $i < 120 } { incr i } {
spawn ssh -l $user 172.41.30.$i
expect {
"yes/no" { send "yes\r";exp_continue }
"id_rsa" { send "yes\r";exp_continue }
"*assword" { send "$passwd\r" ;exp_continue }
"test@" {
send "sudo su -\r"
expect {
"password for test" { send "$passwd\r";exp_continue }
}
}
}
}
expect eof
exit 0
3、批量定义inventory
直接利用for循环进行批量的写入
for i in $(seq 200 240);do echo 192.168.1.$i >> /etc/ansible/hosts;done
