**简介**

ansible实质就是一个网管工具，它可以在本地远程控制远端服务器程序的执行。

**安装ansible**  
安装ansible需要epel源。

![图片.png][.png]

**主要文件**

![图片.png][.png 1]

ansbile.cfg是程序配置文件

hosts是主机文件 被管理主机的清单

主程序文件：1、ansible(命令行工具) 2、ansible-playbook(用来调用运维脚本的) 3、ansible-doc(帮助文档)

**简单操作**

1、编辑/etc/ansible/hosts文件

![图片.png][.png 2]

2、在ansible主机上生成SSH密钥对，用来进行远程管理认证(ansible主机想管理哪台主机，就把自己的公钥发给谁)

![图片.png][.png 3]

\-N 表示不需要密钥密码

3、将ansible主机的公钥拷贝到被管理主机上

![图片.png][.png 4]

4、向被管理主机发出ping命令

![图片.png][.png 5]

webserver 是向谁发出指令

\-m 表示调用功能模块

**获取模块列表**

**通过命令查看功能模块简介**

**ansible常用模块**

1、command

这个模块可以让被管理主机执行一条命令，并返回执行结果

![图片.png][.png 8]

![图片.png][.png 9]

这个模块是ansible默认模块。

但是这个模块不支持管道符

比如

![图片.png][.png 10]

command模块仅仅把echo后面的内容当成需要输出的内容了。

2、shell

这个模块可以支持管道符，而且shell模块的使用范围更大一些。

![图片.png][.png 12]

在本地远程修改了远端主机用户的密码

3、copy 将本地指定文件拷贝到被管理主机上

![图片.png][.png 13]

![图片.png][.png 14]

![图片.png][.png 15]

可以写内容到指定文件中

![图片.png][.png 16]

4、cron 操作远程主机的计划任务

![图片.png][.png 17]

![图片.png][.png 18]

![图片.png][.png 19]

删除任务

![图片.png][.png 20]

![图片.png][.png 21]

5、fetch 从远端主机获取文件

![图片.png][.png 22]

![图片.png][.png 23]

![图片.png][.png 24]

为了方式文件名重复，系统自动创建了10.0.1.11的目录，子目录为各个远端主机的名称

6、file 修改远端主机文件属性

![图片.png][.png 25]

![图片.png][.png 26]

![图片.png][.png 27]

可以用file创建一个目录

![图片.png][.png 28]

![图片.png][.png 29]

7、YUM 管理远端主机使用YUM程序

![图片.png][.png 30]

![图片.png][.png 31]

![图片.png][.png 32]

8、service 管理远端服务器的服务

![图片.png][.png 33]

关闭远端服务器的httpd服务

![图片.png][.png 34]

![图片.png][.png 35]

stopped\\started  restarted\\reloaded

9、uri

获取远端主机httpd的URL资源

![图片.png][.png 36]

10、setup

获取远端主机的ansible参数信息

![图片.png][.png 37]

11、group

在远端服务器上管理组。添加、删除

![图片.png][.png 38]

12、user

在远端服务器上管理用户 比如创建、删除
