一·、批量推送公钥2.推送单个公钥到远程机器
格式: ssh-copy-id -i ~/.ssh/id_rsa.pub username@[ip,hostname]
ssh-copy-id -i ~/.ssh/id_rsa.pub username@192.168.198.x
3.添加ansible hosts
编辑/etc/ansible/hosts,没有则创建些文件。
格式:【主机名】 【主机地址】 【主机密码】 默认是root用户来进行的
[all]
1 ansible_ssh_user="root" ansible_ssh_host=192.168.198.131 ansible_ssh_pass="123456"
2 ansible_ssh_user="root" ansible_ssh_host=192.168.198.134 ansible_ssh_pass="123456"
3 ansible_ssh_user="root" ansible_ssh_host=192.168.198.141 ansible_ssh_pass="123456"
新版的ansible(2.4) hosts有更新, 用以下方式:
[all]
192.168.198.131 ansible_user=root ansible_ssh_pass="123456"
192.168.198.141 ansible_user=root ansible_ssh_pass="123456"
192.168.198.134 ansible_user=root ansible_ssh_pass="123456"
4.批量推送公钥到远程机器
机器多的情况下,使用ssh-copy-id方法有些费时,使用ansible-playbook推送ymal,这里使用到了authoried_keys模块,可以参考 http://docs.ansible.com/authorized_key_module.html
[root@mha ansible]# ls
ansible.cfg hosts push.ssh.ymal roles
[root@mha ansible]# cat push.ssh.ymal
5.执行推送命令
ansible-playbook push.ssh.ymal
[root@mha ansible]# ansible-playbook push.ssh.ymal
PLAY [all] **
TASK [Gathering Facts] **
ok: [192.168.198.134]
ok: [192.168.198.141]

192.168.198.141 : ok=2 changed=0 unreachable=0 failed=0
二·、检查主机组或者是单一个主机
[root@mha ansible-tower-setup-3.1.0]# ansible all -m shell -a "mysql -uroot -p123456 -e ‘use test;show tables‘"
192.168.198.134 | SUCCESS | rc=0 >>
Tables_in_test
t3
t4
t44
t5
tt1
192.168.198.131 | FAILED | rc=127 >>
/bin/sh: mysql: command not found
192.168.198.141 | SUCCESS | rc=0 >>
