云野 Ansible-常用模块
1.ansible实现管理的方式
Ad-Hoc ##利用ansible命令直接完成管理,主要用于临时命令使用场景
playbook ##ansible脚本,主要用于大型项目场景,需要前期的规划
2.Ad-Hoc执行方式中如何获得帮助
ansible-doc ##显示模块帮助的指令
2.1 格式
ansible-doc [参数] [模块…]
2.2 常用参数
-l ##列出可用模块
-s ##显示指定模块的playbook片段
[root@ansible ~]# ansible-doc -l | wc -l
3387
[root@ansible ~]# ansible-doc -s shell
- name: Execute shell commands on targets
shell:
chdir: # Change into this directory before running the command.
cmd: # The command to run followed by optional arguments.
creates: # A filename, when it already exists, this step will *not* be run.
executable: # Change the shell used to execute the command. This expects an absolute path to the executable.
free_form: # The shell module takes a free form command to run, as a string. There is no actual parameter named 'free form'. See
the examples on how to use this module.
removes: # A filename, when it does not exist, this step will *not* be run.
stdin: # Set the stdin of the command directly to the specified value.
stdin_add_newline: # Whether to append a newline to stdin data.
warn: # Whether to enable task warnings.
[root@ansible ~]#
3.ansible命令运行方式及常用参数
3.1 格式:
ansible 清单 -m 模块 -a 模块参数
3.2 常用参数
--version ##显示版本 -m module ##指定模块,默认为command模块 --list ##显示主机列表,也可以用--list-hosts -v ##详细过程 -vv -vvv更详细过程 -k ##提示输入ssh连接密码,默认key认证 -C ##预执行检测 -T ##执行命令的超时时间,默认10s# -u ##指定远程执行的用户 -b ##执行sudo切换身份操作 -become-user=USERNAME ##指定sudo的用户 -K ##提示输入sudo密码
4.ansible的基本颜色代表信
绿色 ##执行成功但为对远程主机做任何改变
黄色 ##执行成功并对远程主机做改变
红色 ##执行失败
5.ansible中的常用模块
5.1 command
注意：Linux中的很多通配符在command模块中不支持
功能: 在远程主机执行命令,此模块为默认模块
常用参数:
| chdir | ##执行命令前先进入到指定目录 |
| cmd | ##运行命令指定 |
| creates | ##如果文件存在将不运行 |
| removes | ##如果文件存在将运行 |
| free_form | ##在远程主机中执行的命令,此参数不需要加 |
