请添加图片描述
今天主要是ansible的基本命令学习,ansible内置了1000+模块,每个模块都可以看做成是一个命令,而且参数各不相同,导致ansible的使用方法多种多样。
我们主要是学习一些常用的命令。

ansible常用命令

ansible

ansible命令是最主要的命令,我们在使用ansible执行任务时都需要这个指令。通过ssh实现配置管理、应用部署、任务执行等功能,建议配置ansible端能基于密钥认证的方式联系各被管理节点。

ansible <host-pattern> [-m module_name] [-a args]
--version 显示版本
-m module 指定模块,默认为command
-v 详细过程 -vv -vVV更详细
--list-hosts 显示主机列表,可简写-list
-k,--ask-pass提示输入ssh连接密码,默认Key验证-K,--ask-become-pass 提示输入sudo时的口令
-C,--check 检查,并不执行
-T,--timeout=TIMEOUT 执行命令的超时时间,默认10s
-u,--user=REMOTE_USER 执行远程执行的用户
-b,--become 代替日版的sudo 切换

示例

#例如,使用ansible调用ping命令联通测试机
#all代表所有主机,也可以单独指定主机分组,或者ip,主机名等
[root@0033 .ssh]# ansible all -m ping

}

ansible-doc命令

ansible-doc命令等于linux中的man命令,主要是查看各个模块的使用方法。该命令是按页展示,支持左右方向键翻看。

ansible-doc [options] [module....]
-a   显示所有模块的文档
-l, --list列出可用模块
-s,--snippet显示指定模块的playbook片段
示例:
ansible-doc -1 列出所有模块
ansible-doc ping 查看指定模块帮助用法
ansible-doc-s ping 查看指定模块帮助用法

示例

[root@0033 .ssh]# ansible-doc ping
> PING    (/usr/lib/python2.7/site-packages/ansible/modules/system/ping.py)

        A trivial test module, this module always returns `pong' on successful contact. It does not make sense in playbooks, but it is
        useful from `/usr/bin/ansible' to verify the ability to login and that a usable Python is configured. This is NOT ICMP ping,
        this is just a trivial test module that requires Python on the remote-node. For Windows targets, use the [win_ping] module
        instead. For Network targets, use the [net_ping] module instead.

  * This module is maintained by The Ansible Core Team
OPTIONS (= is mandatory):

- data
        Data to return for the `ping' return value.
        If this parameter is set to `crash', the module will cause an exception.
        [Default: pong]
        type: str

- name: Try to connect to host, verify a usable python and return `pong' on success
  ping:
      data:                  # Data to return for the `ping' return value. If this parameter is set to `crash', the module will cause an exception.

ansible-playbook

ansible-playbook是执行ansible剧本的命令,这个会在后面学习。

ansible-vault

文件加密工具,主要是保证主机名密码等隐私信息的安全。

ansible-console

基于Console界面与用户交互的执行工具

ansible-galaxy

下载/上传优秀代码或Roles模块的官网平台

ansible的Host-pattern格式

ansible的执行支持*通配符,例如

[root@0033 ~]# ansible 192.168.0.* -m ping
192.168.0.226 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

[root@0033 ~]# ansible "*" -m ping
192.168.0.226 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

[root@0033 ~]# ansible "t*" -m ping
192.168.0.226 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

支持或与运算

ansible “websrvs;appsrvs” -m ping
ansible “192.168.1.10:192.168.1.20”-m ping

ansible的命令执行过程

1.加载自己的配置文件 默认/etc/ansible/ansible.cfg
2.加载自己对应的模块文件,如command
3.通过ansible将模块或命令生成对应的临时py文件,并将该 文件传输至远程服务器的对应执行用户SHOME/.ansible/tmp/ansible-tmp-数字/XXX.PY文件
4.给文件+x执行
5.执行并返回结果
6.删除临时py文件,sleep o退出
执行状态 :
绿色: 执行成功并且不需要做改变的操作
黄色: 执行成功并且对目标主机做变更
红色: 执行失败

ansible的模块使用

Command

:在远程主机执行命令,默认模块,可忽略-m选项,如上面测试的ping指令

[root@0033 ~]# ansible "*" -m ping
192.168.0.226 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

但是command并不支持复杂运算, 如SVARNAME< > | ;& 等;
参考以下指令,command模块会将echo执行成输出指令。

[root@0033 ~]# ansible all -m command -a 'echo test lpasswd --stdin wang'
192.168.0.226 | CHANGED | rc=0 >>
testlpasswd --stdin wang

shell模块

支持复杂运算,比command更高级,但是更为复杂的指令还是适用性不太好

[root@0033 ~]# ansible all -m shell -a 'echo test lpasswd --stdin wang'
192.168.0.226 | CHANGED | rc=0 >>
test lpasswd --stdin wang

Script模块

调用bash执行命令类似 cat /tmp/stanley.md|awk -F’print S1,S2&>/tmp/example.txt 这些复杂命令,即使使用shell也可能会失败,解决办法: 写到脚本时,copy到远程,执行,再把需要的结果拉回执行命令的机器
Script : 运行脚本(自动复制脚本到其他机器)

[root@0033 ~]# ansible all -m script -a './name.sh'
192.168.0.226 | CHANGED => {
    "changed": true, 
    "rc": 0, 
    "stderr": "Shared connection to 192.168.0.226 closed.\r\n", 
    "stderr_lines": [
        "Shared connection to 192.168.0.226 closed."
    ], 
    "stdout": "0037\r\n", 
    "stdout_lines": [
        "0037"
    ]
}

copy模块

将文件复制到其他机器上(开启备份功能)

[root@0033 ~]# ansible all -m copy -a 'src=/root/1.sh dest=/root  backup=yes'
192.168.0.226 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": true, 
    "checksum": "f8615eade69d89da6d00670ff9b1b9085bd0054f", 
    "dest": "/root/1.sh", 
    "gid": 0, 
    "group": "root", 
    "md5sum": "ccdc5a05c6d775679b93ee275980a58f", 
    "mode": "0644", 
    "owner": "root",

    "state": "file", 
    "uid": 0
}

查看测试机是否有这个文件

[root@0033 ~]# ansible all -a 'ls /root/1.sh'
192.168.0.226 | CHANGED | rc=0 >>
/root/1.sh

fetch模块
