ansible操作
一、安装修改管理员密码
二、批量推送公钥
1.使用 ssh-keygen -t rsa生成密钥对
ssh-keygen -t rsa
2.推送单个公钥到远程机器
格式： ssh-copy-id -i ~/.ssh/id_rsa.pub username@
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
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：
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
# ls
ansible.cfghostspush.ssh.ymalroles
# cat push.ssh.ymal
- hosts: all user: root
tasks:
- name: ssh-copy
authorized_key: user=root key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}"
tags:
- sshkey
5.执行推送命令
ansible-playbook push.ssh.ymal
# ansible-playbook push.ssh.ymal
PLAY **
TASK **
ok:
ok:

192.168.198.131 : ok=2 changed=1 unreachable=0 failed=0
192.168.198.134 : ok=2 changed=0 unreachable=0 failed=0
192.168.198.141 : ok=2 changed=0 unreachable=0 failed=0
新增用户和创建密码
# ansible nginx -m shell -a "useradd wsw && echo "123456"| passwd --stdin wsw"
192.168.198.131 | SUCCESS | rc=0 >>
Changing password for user wsw.
passwd: all authentication tokens updated successfully.
192.168.198.134 | SUCCESS | rc=0 >>
Changing password for user wsw.
passwd: all authentication tokens updated successfully.
192.168.198.145 | SUCCESS | rc=0 >>
Changing password for user wsw.
passwd: all authentication tokens updated successfully.
192.168.198.144 | SUCCESS | rc=0 >>
Changing password for user wsw.
passwd: all authentication tokens updated successfully.
三、检查主机组或者是单一个主机
# 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 >>
Tables_in_test
t3
t4
t44
t5
tt1
四、ansible-playbook
1、关于git pull
# cat git.yml
---
- hosts: 192.168.198.131
gather_facts: no
tasks:
- name: mkdir code.
shell: mkdir /root/600
tasks:
- name: git pull the code.
git: repo=git@git.coding.net:wsw26/600.gitdest=/root/600/
2、关于git pull紧接着checkout branch
# cat git.yml
---
- hosts: 192.168.198.131
gather_facts: no
tasks:
- name: mkdir code.
shell: mkdir /root/600
tasks:
- name: git pull the code.
git: repo=git@git.coding.net:wsw26/600.gitdest=/root/600/
tasks:
- git:
repo: git@git.coding.net:wsw26/600.git
dest: /root/600/
version: v1.9.306
客户机能顺利把代码拉下来并切换分支了
四、ansible-tower
