为什么要选择ansible
选择一款配置管理软件总的来说，无外乎从以下几点来权衡利弊
活跃度(社区活跃度)
学习成本
使用成本
编码语言
性能
使用是否广泛
ansible优点
是仅需要ssh和Python即可使用
无客户端
ansible功能强大，模块丰富
上手容易门槛低
基于python开发，做二次开发更容易
使用公司比较多，社区活跃
ansible特性
模块化设计，调用特定的模块来完成特定任务

静态Inventory指的是在文件/etc/ansible/hosts中指定的主机和组，Dynamic
Inventory指通过外部脚本获取主机列表，并按照ansible所要求的格式

批量部署证书文件
• 每次交亏输入密码比较麻烦
• 密码写入配置文件安全性很差
• 丌同主机丌同密码,配置文件要上天
• 使用 key 方式认证,是一个丌错的选择
• 给所有主机部署公钥

模块
ansible-doc
模块的手册，相当于shell的man
ansible-doc -l 列出所有模块
ansible-doc modulename 查看帮助
ping模块
测试网络连通性，ping模块没有参数
注：测试ssh的连通性
ansible host-pattern -m ping
ansible-doc -l | grep shell
[root@ansible ~]# ansible-doc shell
[root@ansible ~]# ansible web -m ping
web2 | SUCCESS => {
"changed": false,
"ping": "pong"
}
web1 | SUCCESS => {
"changed": false,
"ping": "pong"
command模块
默认模块，远程执行命令
用法
[root@ansible ~]# ansible other -m command -a 'uptime >/tmp/a.log'
[root@ansible ~]# pstree -p
├─sshd(677)───sshd(820)───bash(822)───pstree(4726) //与bash相关的操作会失败，比如重定项 ps -ef | grep ssh & metacharacter
A character that, when unquoted, separates words. One of the following:
| & ; ( ) < > space tab 只在ssh进程中执行
[root@ansible ~]# man bash
[root@ansible ~]# /bin/ls //ansible可执行硬盘上有的可执行文件
anaconda-ks.cfg ifcfg-eth0 RPM-GPG-KEY-CentOS-7
模块
shell | raw 模块
shell模块用法基本和command一样，区别是shell模块通过/bin/sh进行执行命令，可以执行任意命令
raw模块,用法和shell 模块一样 ,可以执行任意命令
– 区别是 raw 没有chdir、creates、removes参数
ansible cache -m command -a 'chdir=/tmp touch f1'
ansible cache -m raw -a 'chdir=/tmp touch f2'
ansible cache -m shell -a 'chdir=/tmp touch f1'
//ansible:主机上配置ip与主机名对应关系 /etc/hosts
免密码登录：管理主机可以登录其他托管主机，无需密码
使用ansible 在 db1 db2 主机上批量创建用户zhang3
257 ansible db1 -m shell -a 'useradd zhang3'
258 ansible db2 -m shell -a 'useradd zhang3'
259 ansible db1 -m shell -a 'echo 123456 | passwd --stdin zhang3'
260 ansible db2 -m shell -a 'echo 123456 | passwd --stdin zhang3'
[root@ansible ~]# ansible db -m shell -a 'chage -d 0 zhang3'
script模块
给 app1分组添加用户li4
系统里没有zhang3用户就添加，如果zhang3存在就不添加
修改li4的默认密码123456
[root@ansible ooxx]# vim u.sh

if [ $? != 0 ];then
useradd li4
echo 123456 | passwd –stdin li4

copy 模块
– 复制文件到进程主机
– src:要复制到进程主机的文件在本地的地址,可以是
绝对路径,也可以是相对路径。如果路径是一个目彔,
它将递归复制。在这种情况下,如果路径使用"/"来结
尾,则只复制目彔里的内容,如果没有使用"/"来结尾,
则包含目彔在内的整个内容全部复制,类似亍rsync
– dest:必选项。进程主机的绝对路径,如果源文件是
一个目彔,那么该路径也必须是个目彔
