ansible常用模块有:ansible常用模块raw、command、shell的区别:ping模块用于检查指定节点机器是否连通,用法很简单,不涉及参数,主机如果在线,则回复pong


ansible常用模块

一、ansible常用模块使用详解

ansible常用模块有:

  • ping
  • yum
  • template
  • copy
  • user
  • group
  • service
  • raw
  • command
  • shell
  • script

ansible常用模块rawcommandshell的区别:

  • shell模块调用的/bin/sh指令执行
  • command模块不是调用的shell的指令,所以没有bash的环境变量
  • raw很多地方和shell类似,更多的地方建议使用shell和command模块。但是如果是使用老版本python,需要用到raw,又或者是客户端是路由器,因为没有安装python模块,那就需要使用raw模块了

1.ansible常用模块之ping

ping模块用于检查指定节点机器是否连通,用法很简单,不涉及参数,主机如果在线,则回复pong

[root@ansible ~]# ansible all -m ping 192.168.111.142 | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": false,     "ping": "pong" } 

2.ansible常用模块之command

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。

//查看受控主机的/tmp目录内容 [root@ansible ~]# ansible 192.168.111.142 -a 'ls /tmp' 192.168.111.142 | CHANGED | rc=0 >> ansible_command_payload_z973ukjx systemd-private-ac56c8c9ec59454cbb39a024c91beb72-chronyd.service-S24EYh vmware-root_897-3979643105  //在受控主机的/tmp目录下新建一个文件test [root@ansible ~]# ansible 192.168.111.142 -a 'touch /tmp/test' [WARNING]: Consider using the file module with state=touch rather than running 'touch'.  If you need to use command because file is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message. 192.168.111.142 | CHANGED | rc=0 >>  //查看一下是否创建成功 [root@ansible ~]# ansible 192.168.111.142 -a 'ls /tmp' 192.168.111.142 | CHANGED | rc=0 >> ansible_command_payload_62jkggxf systemd-private-ac56c8c9ec59454cbb39a024c91beb72-chronyd.service-S24EYh test vmware-root_897-3979643105  //command模块不支持管道符,不支持重定向 [root@ansible ~]# ansible 192.168.111.142 -a "echo 'hello world' > /tmp/test" 192.168.111.142 | CHANGED | rc=0 >> hello world > /tmp/test  [root@ansible ~]# ansible 192.168.111.142 -a 'cat /tmp/test' 192.168.111.142 | CHANGED | rc=0 >>  [root@ansible ~]# ansible 192.168.111.142 -a 'ps -ef | grep httpd' 192.168.111.142 | FAILED | rc=1 >> error: garbage option  Usage:  ps [options]   Try 'ps --help <simple|list|output|threads|misc|all>'   or 'ps --help <s|l|o|t|m|a>'  for additional help text.  For more details see ps(1).non-zero return code 

3.ansible常用模块之raw

raw模块用于在远程主机上执行命令,其支持管道符与重定向

//支持重定向 [root@ansible ~]# ansible 192.168.111.142 -m raw -a 'echo "hello world" > /tmp/test' 192.168.111.142 | CHANGED | rc=0 >> Shared connection to 192.168.111.142 closed.  [root@ansible ~]# ansible 192.168.111.142 -a 'cat /tmp/test' 192.168.111.142 | CHANGED | rc=0 >> hello world  //支持管道符 [root@ansible ~]# ansible 192.168.111.142 -m raw -a 'cat /tmp/test | grep -Eo hello' 192.168.111.142 | CHANGED | rc=0 >> hello Shared connection to 192.168.111.142 closed. 

4.ansible常用模块之shell

shell模块用于在受控机上执行受控机上的脚本,亦可直接在受控机上执行命令。
shell模块亦支持管道与重定向。

//查看受控机上的脚本 [root@localhost ~]# ll /scripts/ total 4 -rw-r--r-- 1 root root 43 Oct 23 19:00 test.sh  //使用shell模块在受控机上执行受控机上的脚本 [root@ansible ~]# ansible 192.168.111.142 -m shell -a '/bin/bash /scripts/test.sh &> /tmp/test' 192.168.111.142 | CHANGED | rc=0 >>  [root@ansible ~]# ansible 192.168.111.142 -m shell -a 'cat /tmp/test' 192.168.111.142 | CHANGED | rc=0 >> 123456 123 456 

5.ansible常用模块之script

script模块用于在受控机上执行主控机上的脚本

[root@ansible ~]# ll /scripts/ total 4 -rw-r--r-- 1 root root 48 Oct 23 19:06 a.sh  [root@ansible ~]# ansible 192.168.111.142 -m script -a '/scripts/a.sh &> /tmp/a' 192.168.111.142 | CHANGED => {     "changed": true,     "rc": 0,     "stderr": "Shared connection to 192.168.111.142 closed.rn",     "stderr_lines": [         "Shared connection to 192.168.111.142 closed."     ],     "stdout": "",     "stdout_lines": [] }  //查看受控机上的/tmp/a文件内容 [root@ansible ~]# ansible 192.168.111.142 -m shell -a 'cat /tmp/a' 192.168.111.142 | CHANGED | rc=0 >> 123 456 hello world 

6.ansible常用模块之template

template模块用于生成一个模板,并可将其传输至远程主机上。

[root@ansible ~]# ansible 192.168.111.142 -m template -a 'src=/etc/yum.repos.d/CentOS-Base.repo dest=/etc/yum.repos.d/centos.repo' 192.168.111.142 | CHANGED => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": true,     "checksum": "8bbf30b2d80c3b97292ca7b32f33ef494269a5b8",     "dest": "/etc/yum.repos.d/centos.repo",     "gid": 0,     "group": "root",     "md5sum": "ed031c350da2532e6a8d09a4d9b05278",     "mode": "0644",     "owner": "root",     "size": 1653,     "src": "/root/.ansible/tmp/ansible-tmp-1666530145.7581205-29420421110479/source",     "state": "file",     "uid": 0 }  //查看受控机上是否有163源 [root@localhost ~]# ls /etc/yum.repos.d/ centos.repo 

7.ansible常用模块之yum

yum模块用于在指定节点机器上通过yum管理软件,其支持的参数主要有两个

  • name:要管理的包名
  • state:要进行的操作

state常用的值:

  • latest:安装软件
  • installed:安装软件
  • present:安装软件
  • removed:卸载软件
  • absent:卸载软件

若想使用yum来管理软件,请确保受控机上的yum源无异常。

//在受控机上查询看vsftpd软件是否安装 [root@localhost ~]# rpm -qa|grep httpd [root@localhost ~]#   //在ansible主机上使用yum模块在受控机上安装httpd [root@ansible ~]# ansible 192.168.111.142 -m yum -a 'name=httpd state=present' 192.168.111.142 | CHANGED => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": true,     "msg": "",     "rc": 0,     "results": [         "Installed: mailcap-2.1.48-3.el8.noarch",         "Installed: httpd-2.4.37-43.module_el8.5.0+1022+b541f3b1.x86_64",         "Installed: apr-1.6.3-12.el8.x86_64",         "Installed: httpd-filesystem-2.4.37-43.module_el8.5.0+1022+b541f3b1.noarch",         "Installed: apr-util-1.6.1-6.el8.x86_64",         "Installed: apr-util-bdb-1.6.1-6.el8.x86_64",         "Installed: httpd-tools-2.4.37-43.module_el8.5.0+1022+b541f3b1.x86_64",         "Installed: centos-logos-httpd-85.8-2.el8.noarch",         "Installed: mod_http2-1.15.7-3.module_el8.4.0+778+c970deab.x86_64",         "Installed: apr-util-openssl-1.6.1-6.el8.x86_64"     ] }  //查看受控机上是否安装了httpd [root@localhost ~]# rpm -qa|grep httpd httpd-filesystem-2.4.37-43.module_el8.5.0+1022+b541f3b1.noarch centos-logos-httpd-85.8-2.el8.noarch httpd-2.4.37-43.module_el8.5.0+1022+b541f3b1.x86_64 httpd-tools-2.4.37-43.module_el8.5.0+1022+b541f3b1.x86_64 

8.ansible常用模块之copy

copy模块用于复制文件至远程受控机。

[root@ansible ~]# ls /scripts/ a.sh [root@ansible ~]# ansible 192.168.111.142 -m copy -a 'src=/scripts/a.sh dest=/scripts/a' 192.168.111.142 | CHANGED => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": true,     "checksum": "91bb6c7a9d3e47e330dd408c5209d8c36226e014",     "dest": "/scripts/a/a.sh",     "gid": 0,     "group": "root",     "md5sum": "d92a6bbb430fd85b35bfc1f0a8035bdc",     "mode": "0644",     "owner": "root",     "size": 48,     "src": "/root/.ansible/tmp/ansible-tmp-1666530391.1743026-219581542309073/source",     "state": "file",     "uid": 0 }  [root@ansible ~]# ansible 192.168.111.142 -m shell -a 'ls /scripts/a' 192.168.111.142 | CHANGED | rc=0 >> a.sh 

9.ansible常用模块之group

12.ansible常用模块之file

file 模块可以帮助我们完成一些对文件的基本操作。比如,创建文件或目录、删除文件或目录、修改文件权限等

force:需要在两种情况下强制创建软链接,一种是源文件不存在,但之后会建立的情况下;另一种是目标软 链接已存在,需要先取消之前的软链,然后创建新的软链,有两个选项:yes|no group:定义文件/目录的属组 mode:定义文件/目录的权限 owner:定义文件/目录的属主 path:必选项,定义文件/目录的路径 recurse:递归的设置文件的属性,只对目录有效 src:要被链接的源文件的路径,只应用于state=link的情况 dest:被链接到的路径,只应用于state=link的情况 state: =directory:如果目录不存在,创建目录 =file:即使文件不存在,也不会被创建 =link:创建软链接 =hard:创建硬链接 =touch:如果文件不存在,则会创建一个新的文件,如果文件或目录已存在,则更新其最后修改时间 =absent:删除目录、文件或者取消链接文件 
//创建文件 [root@ansible ~]# ansible 192.168.111.142 -m file -a 'path=/tmp/abc state=touch owner=root group=root' 192.168.111.142 | CHANGED => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": true,     "dest": "/tmp/abc",     "gid": 0,     "group": "root",     "mode": "0644",     "owner": "root",     "size": 0,     "state": "file",     "uid": 0 }  //创建目录 [root@ansible ~]# ansible 192.168.111.142 -m file -a 'path=/tmp/CBA state=directory mode=0755' 192.168.111.142 | CHANGED => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": true,     "gid": 0,     "group": "root",     "mode": "0755",     "owner": "root",     "path": "/tmp/CBA",     "size": 6,     "state": "directory",     "uid": 0 }  //查看 [root@ansible ~]# ansible 192.168.111.142 -m shell -a 'ls -l /tmp/' 192.168.111.142 | CHANGED | rc=0 >> total 0 drwxr-xr-x  2 root root  6 Oct 23 21:25 CBA -rw-r--r--  1 root root  0 Oct 23 21:24 abc drwx------  2 root root 41 Oct 23 21:26 ansible_command_payload_8kzca8ed drwx------  3 root root 17 Oct 23 21:02 systemd-private-bf7fe2a05a0f43fdab39626e122a4453-chronyd.service-tvBXFi drwx------  2 root root  6 Oct 23 21:02 vmware-root_894-2730693566 drwx------. 2 root root  6 Oct 23 21:00 vmware-root_903-3979774182
