Ansible常用模块介绍
1、 ansible-doc
希望知道更加详细的module的信息，最好的方法是使用ansible自带的ansible-doc的-s选项
[root@node1 ~]# ansible-doc -s raw
- name: Executes a low-down and dirty SSH command
action: raw
executable # change the shell used to execute the command. Should be an absolute path to the
executable. when using privilege escalation
(`become'), a default shell will be assigned if
one is not provided as privilege escalation
requires a shell.
free_form= # the raw module takes a free form command to run. There is no parameter actually
named 'free form'; see the examples!
[root@node1 ~]#
[root@node1 ~]# ansible-doc -s shell
- name: Execute commands in nodes.
action: shell
chdir # cd into this directory before running the command
creates # a filename, when it already exists, this step will *not* be run.
executable # change the shell used to execute the command. Should be an absolute path to the
executable.
free_form= # The shell module takes a free form command to run, as a string. There's not an
actual option named "free form". See the
examples!
removes # a filename, when it does not exist, this step will *not* be run.
warn # if command warnings are on in ansible.cfg, do not warn about this particular
line if set to no/false.
[root@node1 ~]#
[root@node1 ~]# ansible-doc -s command
- name: Executes a command on a remote node
action: command
chdir # cd into this directory before running the command
creates # a filename or (since 2.0) glob pattern, when it already exists, this step will
*not* be run.
executable # change the shell used to execute the command. Should be an absolute path to the
executable.
free_form= # the command module takes a free form command to run. There is no parameter
actually named 'free form'. See the examples!
removes # a filename or (since 2.0) glob pattern, when it does not exist, this step will
*not* be run.
warn # if command warnings are on in ansible.cfg, do not warn about this particular
line if set to no/false.
[root@node1 ~]# ansible localhost -m raw -a "echo hello"
localhost | SUCCESS | rc=0 >>
hello
[root@node1 ~]#2、 常用模块之command/shell/raw
使用模块 command或者shell或者raw都能调用对象机器上的某条指令或者某个可执行文
- command模块，执行远程命令
- script模块 ，在远程主机执行主控端的shell/python脚本
- shell模块 ，执行远程主机的shell/python脚本
- raw模块 ，类似于command模块、支持管道传递
（1）直接执行脚本
[root@node1 ~]# ansible 192.168.80.133 -m raw -a "/tmp/test.sh"
192.168.80.133 | SUCCESS | rc=0 >>
Mon Oct 2 08:52:08 EDT 2017
Shared connection to 192.168.80.133 closed.
[root@node1 ~]# ansible 192.168.80.133 -m shell -a "/tmp/test.sh"
192.168.80.133 | SUCCESS | rc=0 >>
Mon Oct 2 08:52:21 EDT 2017
[root@node1 ~]# ansible 192.168.80.133 -m command -a "/tmp/test.sh"
192.168.80.133 | SUCCESS | rc=0 >>
Mon Oct 2 08:52:29 EDT 2017
[root@node1 ~]#（2） 是否支持管道
- command 不支持管道
- shell 支持管道
- raw 支持管道
[root@node1 ~]# ansible 192.168.80.133 -m shell -a "ps -ef |wc -l"
192.168.80.133 | SUCCESS | rc=0 >>
96
[root@node1 ~]# ansible 192.168.80.133 -m raw -a "ps -ef |wc -l"
192.168.80.133 | SUCCESS | rc=0 >>
93
Shared connection to 192.168.80.133 closed.
[root@node1 ~]# ansible 192.168.80.133 -m command -a "ps -ef |wc -l"
192.168.80.133 | FAILED | rc=1 >>
error: garbage option
Usage:
ps [options]
Try 'ps --help command不支持命令行通配符
[root@node1 ~]# ansible 192.168.80.133 -m command -a 'ls -l /tmp/*.sh'
192.168.80.133 | FAILED | rc=2 >>
ls: cannot access /tmp/*.sh: No such file or directory
[root@node1 ~]# ansible 192.168.80.133 -m shell -a 'ls -l /tmp/*.sh'
192.168.80.133 | SUCCESS | rc=0 >>
-rwxr-xr-x 1 root root 17 Sep 28 10:49 /tmp/test.sh
[root@node1 ~]# ansible 192.168.80.133 -m raw -a 'ls -l /tmp/*.sh'
192.168.80.133 | SUCCESS | rc=0 >>
-rwxr-xr-x 1 root root 17 Sep 28 10:49 /tmp/test.sh
Shared connection to 192.168.80.133 closed.
[root@node1 ~]#2017-11-17 补充：
[root@hadron web_store]# ansible nb1 -m command -a "/etc/init.d/zookeeper-server status"
nb1 | SUCCESS | rc=0 >>
Mode: leaderZooKeeper JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
[root@hadron web_store]# ansible nb1 -m shell -a "/etc/init.d/zookeeper-server status"
nb1 | SUCCESS | rc=0 >>
Mode: leaderZooKeeper JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
[root@hadron web_store]# ansible nb1 -m raw -a "/etc/init.d/zookeeper-server status"
nb1 | SUCCESS | rc=0 >>
ZooKeeper JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
Mode: leader
Shared connection to nb1 closed.
[root@hadron web_store]#
3、 常用模块之copy
使用copy模块，可以实现向目标机器进行远程copy的能力。
| 参数 | 说明 |
|---|---|
| src | 被复制到远程主机的本地对象文件或者文件夹，可以是绝对路径，也可以是相对路径。 |
| dest | 被复制到远程主机的本地对象文件或者文件夹 |
| mode | 复制对象的设定权限 |
| backup | 在文件存在的时候可以选择覆盖之前，将源文件备份.设定值：yes/no 缺省为yes |
| force | 是否强制覆盖.设定值：yes/no 缺省为yes |
| … | 其余请自行ansible-doc -s copy |
default的情况下，force是yes的，所以什么都不写，文件存在的情况是会被覆盖的
注意：
script模块 ，在远程主机执行主控端的shell/python脚本。也就是说 script模块实现了将主控节点的脚本复制到远程节点，然后在远程节点执行脚本。
[root@hadron ~]# cat /root/test/test.sh
#!/bin/bash
date
ls /root
[root@hadron ~]# ansible 192.168.1.161 -m script -a "/root/test/test.sh"
192.168.1.161 | SUCCESS => {
"changed": true,
"rc": 0,
"stderr": "Shared connection to 192.168.1.161 closed.\r\n",
"stdout": "2017年 11月 03日 星期五 09:16:34 CST\r\nanaconda-ks.cfg books.txt\t scripts\ttest1\t zsh_test.txt\r\nbooks.bak\t mapred-site.xml sshKeyGen.sh\tyarn-site.xml\r\n",
"stdout_lines": [

"anaconda-ks.cfg books.txt\t scripts\ttest1\t zsh_test.txt",
"books.bak\t mapred-site.xml sshKeyGen.sh\tyarn-site.xml"
]
}
[root@hadron ~]# 4、setup模块
setup模块，用于收集对象机器的基本设定信息
（1） 不用option的情况会输出所有相关的对象机器的facts
[root@node1 ~]# ansible 192.168.80.133 -m setup
192.168.80.133 | SUCCESS => {
"ansible_facts": {
"ansible_all_ipv4_addresses": [

...（2） setup常用Option：filter
比如收集对象机器的环境变量信息
[root@node1 ~]# ansible 192.168.80.133 -m setup -a "filter=ansible_env"

[root@node1 ~]# 5、user/group模块
- user模块，用于管理用户。
- group模块，用于管理group。
[root@node1 ~]# echo [slaves] >> /etc/ansible/hosts
[root@node1 ~]# echo node2 >> /etc/ansible/hosts
[root@node1 ~]# echo node3 >> /etc/ansible/hosts使用user模块添加用户
[root@node1 ~]# ansible node3 -m command -a "id test01"
node3 | FAILED | rc=1 >>
id: test01: no such user
[root@node1 ~]# ansible node3 -m user -a "name=test01 group=root"

}
[root@node1 ~]# ansible node3 -m shell -a "cat /etc/group |grep testgrp01"
node3 | FAILED | rc=1 >>
[root@node1 ~]# 6、yum模块
使用yum包管理器来管理软件包，其选项有：
name：要进行操作的软件包的名字，也可以传递一个url或者一个本地的rpm包的路径
state：状态（present-已安装，absent-未安装（卸载），latest-最新的）
#确保vim 包已经安装，但不更新
ansible ip -m yum -a "name=vim state=present"
#确保安装包到一个特定的版本
ansible ip -m yum -a "name=vim -7.4 state=present"
#确保一个软件包是最新版本
ansible ip -m yum -a "name=vim state=latest"
#确保一个软件包没有被安装
ansible ip -m yum -a "name=vim state=absent"使用yum模块删除httpd
[root@node1 ~]# ansible node3 -m shell -a "rpm -qa |grep httpd"
[WARNING]: Consider using yum, dnf or zypper module rather than running rpm

7、service模块
service模块用于管理服务
该模块包含如下选项：
arguments：给命令行提供一些选项
enabled：是否开机启动 yes|no
name：必选项，服务名称
state：对当前服务执行启动，停止、重启、重新加载等操作（started,stopped,restarted,reloaded）
[root@node1 ~]# ansible node2 -m service -a "name=httpd state=started enabled=yes"
