1、ansible批量增加sshkey脚本

#!/usr/bin/python
#coding=utf-8
import pexpect
import sys 
import os

#列表里面写入你要增加的服务器IP
servers = [
'xxxx@192.168.1.7',
'xxxx@192.168.1.11',
'ssss@192.168.1.3',
...
'xxxx@192.168.1.49'];

def sendPublicKey(servers):
for server in servers:
child = pexpect.spawn("ssh-copy-id -i /root/.ssh/id_rsa.pub %s" %(server))
index = child.expect(["yes/no","password","exist",pexpect.exceptions.EOF,pexpect.TIMEOUT])
if index != 0 and index != 1:
print("未向此服务器%s上传公钥" %(server))
child.close(force=True)
else:
print("开始上传公钥")
child.sendline('yes')
child.expect("password:")
child.sendline('szprize2018')
child.expect("added")
print("上传完毕")
print
print("全部上传完毕！")

sendPublicKey(servers)

2、增加时，碰到异常IP无法发送密钥时处理：

ssh-keygen -f "~/.ssh/known_hosts" -R 192.168.1.8

删掉ssh生成的缓存

3、ansible实用命令

ansible常用的一些命令：

ansible all -a "bash /mnt/script/push_svnup.sh"
ansible all -s -a "ls /usr/bin/reivew" 使用sudo命令
ansible all -m copy -a "src=/etc/ansible/hosts dest=/etc/ansible/hosts" 远程拷贝文件到目标服务器的上面去

yum模块
ansible all -m yum -a "name=httpd state=latest" 升级httpd
ansible all -m yum -a "name=ntp state=installed" 安装包
ansible all -m yum -a "name=ansible stare=absent" 卸载包

file模块
ansible webserver -m file -a "dest=/usr/bin/review.sh mode=755 owner=root group=wwww" 更改文件状态
ansible webservers -m file -a "dest=/a/b/c/d mode=755 owner=www group=www state=new" 新建文件夹
ansible webserver -m file -a "dest=/tmp/hosts state=absent" 删除文件
ansible webserver -m file -a "src=/usr/bin/review.sh dest=/usr/bin/review mode=755 state=link"软链接

service模块
确定服务都是开启的
#ansible all -m service -a "name=httpd state=started"
重启服务
#ansibel all -m service -a "name=httpd state=restarted"
关闭服务
#ansible all -m service -a "name=httpd state=stoped"

user模块
ansible all -m shell -a "echo 123456 |passwd --stdin root" 更换密码
#ansible all -m user -a "name=test password=<abc>" 新建用户跟密码
#ansible all -m user -a "name=test state=absent"

4、paybook
实例：批量创建维护账户
# vi useradd.yml
---
- hosts: all
user: root
sudo: no
vars:
#password: python -c 'import crypt; print crypt.crypt("devops1232", "fanghanyun")'
user: fanghanyun
tasks:
- name: add user
action: user name={{ user }} password=faJxjj/6hKXPs update_password=always shell=/bin/bash home=/home/{{ user }}
tags:

#vi useradd.yml
- hosts: all
remote_user: root
tasks:
- name: change password for root
shell: echo '{{ item.password }}' |passwd --stdin root
when: ansible_eth0.ipv4.address == '{{ item.ip }}'
with_items:
- { ip: "ip1", password: 'password1' }
- { ip: "ip2", password: 'password2' }
- { ip: "ip3", password: 'password3' }
