文件传输
scp：
Ansible 能够以并行的方式同时 SCP 大量的文件到多台机器. 命令如下:
user1@master:~$ ansible host -i ansible_host -m copy -a "src=/home/user1/scptest.tar.gz dest=/home/user1/scptest.tar.gz"
file 文件模块：
修改文件权限
user1@master:~$ ansible host -i ansible_host -m file -a "dest=/home/user1/bb mode=600" 192.168.108.22 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": true, "gid": 1001, "group": "user1", "mode": "0600", "owner": "user1", "path": "/home/user1/bb", "size": 0, "state": "file", "uid": 1001 }
同时可以修改文件的权限，所有者与组信息；继续添加参数如：owner=user1 group=user1 ;
递归删除：
user1@master:~$ ansible host -i ansible_host -m file -a "dest=/home/user1/aa state=absent" 192.168.108.22 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": true, "path": "/home/user1/aa", "state": "absent" } 192.168.108.23 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": true, "path": "/home/user1/aa", "state": "absent" }
软件包管理
参数介绍：
-m : apt 或 yum
name参数：软件包名称，比如：nginx
state参数：软件包状态，present表示安装，absent表示删除
update_cache参数：安装软件前是否更新缓存，如果update_cache=true表示安装前更新，默认是不更新
apt 安装相关包：
root@master:/home/user1# ansible host -i ansible_host -m apt -a "name=nginx state=present" 192.168.108.23 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "cache_update_time": 1679452175, "cache_updated": false, "changed": true, "stderr": "", "stderr_lines": [],
apt 删除相关包：
root@master:/home/user1# ansible host -i ansible_host -m apt -a "name=nginx state=msg" 192.168.108.22 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": true, "stderr": "", "stderr_lines": [],
Service 服务模块： - enabled
Whether the service should start on boot.
*At least one of state and enabled are required.*
[Default: (null)]
type: bool
-name
Name of the service.
- state
`started'/`stopped' are idempotent actions that will not run commands unless necessary.
`restarted' will always bounce the service.
`reloaded' will always reload.
*At least one of state and enabled are required.*
Note that reloaded will start the service if it is not already started, even if your chosen init system wouldn't normally.
(Choices: reloaded, restarted, started, stopped)[Default: (null)]
如启动防火墙：
root@master:/home/user1# ansible host -i ansible_host -m service -a "name=ufw state=started" 192.168.108.23 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": true, "name": "ufw", "state": "started",
关闭与重启直接修改state 参数的值即可；
