一、常用模块
1.ping 模块
用于确认与对象机器是否能够ping通，正常情况返回pong。可以设置data
不是ICMP ping，只是一个简单的模块
对于windows目标，请改用win_ping模块
对于网络目标，请改用net_ping模块
1 # 默认返回是pong
2 [root@Ansible ~]# ansible web -m ping
3 192.168.8.66 | SUCCESS => {
4 "changed": false,
5 "ping": "pong"
6 }
7
8 # 设置返回值是hello
9 [root@Ansible ~]# ansible web -m ping -a "data=hello"
10 192.168.8.66 | SUCCESS => {
11 "changed": false,
12 "ping": "hello"
13 }
14
15 # 设置返回值是crash，模块导致异常
16 [root@Ansible ~]# ansible web -m ping -a "data=crash"
17 192.168.8.66 | FAILED! => {
18 "changed": false,
19 "module_stderr": "Shared connection to 192.168.8.66 closed.\r\n",
20 "module_stdout": "Traceback (most recent call last):\r\n File \"/tmp/ansible_oNemnu/ansible_module_ping.py\", line 84, in <module>\r\n main()\r\n File \"/tmp/ansible_oNemnu/ansible_module_ping.py\", line 74, in main\r\n raise Exception(\"boom\")\r\nException: boom\r\n",
21 "msg": "MODULE FAILURE",
22 "rc": 1
23 }
2.command 模块
command模块用于在远程主机上执行命令，ansible默认就是使用command模块。
command模块有一个缺陷就是不能使用管道符和重定向功能
1 [root@aliyun ~]# ansible all -a 'pwd' 2 yxd_2 | CHANGED | rc=0 >> 3 /app/yxd 4 mantis_2 | CHANGED | rc=0 >> 5 /app/mantis 6 mantis_1 | CHANGED | rc=0 >> 7 /app/mantis 8 yxd_1 | CHANGED | rc=0 >> 9 /app/yxd
对于Windows目标，请改用win_command模块
