<div class="tip share">请注意，本文编写于 2040 天前，最后修改于 1789 天前，其中某些信息可能已经过时。</div>

## 1. 命令行参数
```
-v,–verbose                 详细模式，如果命令执行成功，输出详细的结果(-vv –vvv -vvvv)
-i PATH,–inventory=PATH     　　　　　指定host文件的路径，默认是在/etc/ansible/hosts(生产环境经常用到)
-f NUM,–forks=NU            NUM是指定一个整数，默认是5，指定fork开启同步进程的个数。
-m NAME,–module-name=NAME           指定使用的module名称，默认是command
-m DIRECTORY,–module-path=DIRECTORY     指定module的目录来加载module，默认是/usr/share/ansible,
-a,MODULE_ARGS              指定module模块的参数
-k,-ask-pass                提示输入ssh的密码，而不是使用基于ssh的密钥认证
-sudo                           指定使用sudo获得root权限(生产环境经常用到)
-K,-ask-sudo-pass               提示输入sudo密码，与–sudo一起使用 (生产环境经常用到)
-u USERNAME,-user=USERNAME          指定移动端的执行用户
-C,-check                       测试此命令执行会改变什么内容，不会真正的去执行
```

## 2. command模块测试环境
```
[root@temp01 ~]# ansible all -a "pwd"
192.168.3.70 | SUCCESS | rc=0 >>
/root

192.168.3.60 | SUCCESS | rc=0 >>
/root

[root@temp01 ~]# ansible all -m command -a "pwd"　　　　#-m command 原来是可以省略的，ansible 默认模块就是command
　192.168.3.70 | SUCCESS | rc=0 >>
　/root

192.168.3.60 | SUCCESS | rc=0 >>
　/root
```
 
## 3. 再用ping模块

```
#-f 参数用法
[root@temp01 ~]# ansible all -m ping -f 1　　　　#all 表示hosts里面所有主机 -m 调用模块 -f 指定同步进程数
192.168.3.60 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
192.168.3.70 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
#-C参数用法
[root@temp01 ~]# ansible all -m ping -f 1 -C　　
192.168.3.60 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
192.168.3.70 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
```

## 4. user模块

```
[root@temp01 ~]# ansible db -m user -a 'name=DBA uid=505 home=/home/dba shell=/sbin/nologin'
192.168.3.70 | SUCCESS => {
    "changed": true,
    "comment": "",
    "createhome": true,
    "group": 505,
    "home": "/home/dba",
    "name": "DBA",
    "shell": "/sbin/nologin",
    "state": "present",
    "system": false,
    "uid": 505
}
[root@temp01 ~]# ansible db -m user -a 'name=DBA state=absent'　　　　#state属性有：present表示添加,absend表示删除，state属性默认是present
192.168.3.70 | SUCCESS => {
    "changed": true,
    "force": false,
    "name": "DBA",
    "remove": false,
    "state": "absent"
}

```
 修改用户密码

```
[root@temp01 ansible_playbook]# ansible all -m shell -a 'echo "123456" | passwd  foo --stdin'
192.168.3.60 | SUCCESS | rc=0 >>
Changing password for user foo.
passwd: all authentication tokens updated successfully.

192.168.3.70 | SUCCESS | rc=0 >>
Changing password for user foo.
passwd: all authentication tokens updated successfully.
```

## 看看下面这个坑

```
[root@temp01 ~]# ansible all -m cron -a "name=cat minute='*/1' job='ls /root'"
192.168.3.70 | FAILED! => {
    "changed": false,
    "failed": true,
    "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
}
192.168.3.60 | FAILED! => {
    "changed": false,
    "failed": true,
    "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
}
```
```
[root@temp01 ~]# ansible all -m copy -a "src=/etc/ansible/hosts dest=/root mode=600"
192.168.3.60 | FAILED! => {
    "changed": false,
    "checksum": "8add7a4e56ae6f7a1c6d0218ce757510d195bb3c",
    "failed": true,
    "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
}
192.168.3.70 | FAILED! => {
    "changed": false,
    "checksum": "8add7a4e56ae6f7a1c6d0218ce757510d195bb3c",
    "failed": true,
    "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
}
```
需要在客户端安装libselinux-python库

## yum模块

```
[root@temp01 ~]# ansible all -m yum -a 'name=libselinux-python state=present'
192.168.3.70 | SUCCESS => {
    "changed": true,

    ]
}
```

## service 模块

```
[root@temp01 ~]# ansible all -m service -a 'name=sshd state=restarted'　　#state属性有running,started,stopped,restarted,reloaded
192.168.3.60 | SUCCESS => {
    "changed": true,
    "name": "sshd",
    "state": "started"
}
192.168.3.70 | SUCCESS => {
    "changed": true,
    "name": "sshd",
    "state": "started"
}
```

## yum模块还是介绍下

```
[root@temp01 ~]# ansible all -m yum -a 'name=ntp state=present'　　　　#state属性有absent,present,installed,removed,latest
192.168.3.70 | SUCCESS => {
    "changed": false,
    "msg": "",
    "rc": 0,
    "results": [
        "ntp-4.2.6p5-1.el6.centos.x86_64 providing ntp is already installed"
    ]
}
192.168.3.60 | SUCCESS => {
    "changed": false,
    "msg": "",
    "rc": 0,
    "results": [
        "ntp-4.2.6p5-1.el6.centos.x86_64 providing ntp is already installed"
    ]
}
```

## script模块 远程执行脚本

```
[root@temp01 ~]# cat ansible.sh　　　　　　　　　　　　　　#脚本内容
#!/bin/bash
echo "Hello world" >>/root/ansible.log
[root@temp01 ~]# ansible all -m script -a 'ansible.sh'
192.168.3.70 | SUCCESS => {
    "changed": true,
    "rc": 0,
    "stderr": "",
    "stdout": "",
    "stdout_lines": []
}
192.168.3.60 | SUCCESS => {
    "changed": true,
    "rc": 0,
    "stderr": "",
    "stdout": "",
    "stdout_lines": []
}

[root@example_02 ~]# pwd　　　　　　　　　　#跳转到客户端验证
/root
[root@example_02 ~]# cat ansible.log
Hello world
```

## shell模块

shell 模块与command模块区别 ，shell支持管道符和变更，下面这个例子说明问题

```
[root@temp01 ~]# ansible all -m mommand -a 'cat /etc/passwd | grep root'
ERROR! this task 'mommand' has extra params, which is only allowed in the following modules: command, win_command, shell, win_shell, script, include, include_vars, add_host, group_by, set_fact, raw, meta
[root@temp01 ~]# ansible all -m shell -a 'cat /etc/passwd | grep root'
192.168.3.70 | SUCCESS | rc=0 >>
root:x:0:0:root:/root:/bin/bash
operator:x:11:0:operator:/root:/sbin/nologin

192.168.3.60 | SUCCESS | rc=0 >>
root:x:0:0:root:/root:/bin/bash
operator:x:11:0:operator:/root:/sbin/nologin
```

## file模块

### 修改文件属性

```
[root@temp01 ~]# ansible all -m file -a 'path=/root/ansible.log owner=root mode=777 group=root'　　　　　　#修改文件属性
192.168.3.60 | SUCCESS => {
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0777",
    "owner": "root",
    "path": "/root/ansible.log",
    "secontext": "unconfined_u:object_r:admin_home_t:s0",
    "size": 12,
    "state": "file",
    "uid": 0
}
192.168.3.70 | SUCCESS => {
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0777",
    "owner": "root",
    "path": "/root/ansible.log",
    "secontext": "unconfined_u:object_r:admin_home_t:s0",
    "size": 12,
    "state": "file",
    "uid": 0
}
```
### 新建目录：类 mkdir -p

```
[root@temp01 ~]# ansible all -m file -a 'dest=/root/1/2/3/4/ mode=755 owner=root group=root state=directory'
192.168.3.60 | SUCCESS => {
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0755",
    "owner": "root",
    "path": "/root/1/2/3/4/",
    "secontext": "unconfined_u:object_r:admin_home_t:s0",
    "size": 4096,
    "state": "directory",
    "uid": 0
}
192.168.3.70 | SUCCESS => {
    "changed": true,
    "gid": 0,
    "group": "root",
    "mode": "0755",
    "owner": "root",
    "path": "/root/1/2/3/4/",
    "secontext": "unconfined_u:object_r:admin_home_t:s0",
    "size": 4096,
    "state": "directory",
    "uid": 0
}

```
###删除目录文件

```
[root@temp01 ~]# ansible all -m file -a 'dest=/root/1/2/3/4/  state=absent'
192.168.3.60 | SUCCESS => {
    "changed": true,
    "path": "/root/1/2/3/4/",
    "state": "absent"
}
192.168.3.70 | SUCCESS => {
    "changed": true,
    "path": "/root/1/2/3/4/",
    "state": "absent"
}

[root@example_02 ~]# cd 1/2/3/4　　　　　　　　　　　　#跳转验证
-bash: cd: 1/2/3/4: No such file or directory
[root@example_02 ~]#
```

[root@temp01 ~]# ansible all -m command -a "pwd"　　　　#-m command 原来是可以省略的，ansible 默认模块就是command
　192.168.3.70 | SUCCESS | rc=0 >>

## 3. 再用ping模块

## 4. user模块

```
 修改用户密码

192.168.3.70 | SUCCESS | rc=0 >>
Changing password for user foo.
passwd: all authentication tokens updated successfully.
```
