  • setup:查看远程主机的基本信息
  • filesystem:在块设备上创建文件系统
  • mount:配置挂载点
  • synchronize:使用rsync同步文件
  • get_url:该模块主要用于从http、ftp、https服务器上下载文件(类似于wget)
  • package:使用os包管理器安装,升级和删除包
  • stat:获取远程主机文件状态信息。
  • unarchive: 用于解压文件
  • command:在远程主机上执行命令
  • raw:类似于shell模块,支持管道

  • systemd:  用于管理服务(CentOS7)后使用
  • hostname: 管理远程主机的主机名。

2.模块的使用

 查看模块帮助

1 [root@test-1 bin]# ansible-doc -l                            #查看所有模块
2 [root@test-1 bin]#ansible-doc -s MODULE_NAME           #查看指定模块的详细帮助

3.ansible命令应用基础

   使用语法:

1 ansible <host-pattern> [-f forks] [-m module_name] [-a args]

   注释:

  • -f   forks:启动的并发线程数
  • -m module_name:  要使用的模块
  • -a  args:模块特有的参数

4.模块使用案例

 4.1 ping模块

    测试主机是否通的,用法很简单,如果成功就返回的是pong。

 1 [root@test-1 ansible]# ansible test -m ping
 2 [DEPRECATION WARNING]: DEFAULT_SUDO_USER option, In favor of Ansible Become, which is a generic framework. See become_user. , use become instead. This feature will be 
 3 removed in version 2.8. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
 4 192.168.3.174 | SUCCESS => {
 5     "changed": false, 
 6     "ping": "pong"
 7 }
 8 192.168.3.175 | SUCCESS => {
 9     "changed": false, 
10     "ping": "pong"
11 }

 4.2 file-模块
       file模块主要用于远程主机上的文件操作,file模块包含如下选项:

 1 force:需要在两种情况下强制创建软连接。
 2    • 一种是源文件不存在但之后会创建的情况下;
 3    • 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 
 4 group:定义文件/目录的属组
 5 owner:定义文件/目录的属主
 6 mode:定义文件/目录的权限
 7 path:必选项,定义文件/目录的路径
 8 recurse:递归设置文件的属性,只对目录有效
 9 src:要被链接的源文件的路径,只应用于state=link的情况
10 dest:被链接到的路径,只应用于state=link的情况 
11 state:定义文件状态
12    • directory:如果目录不存在,创建目录
13    • file:即使文件不存在,也不会被创建
14    • link:创建软链接
15    • hard:创建硬链接
16    • 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
17    • absent:删除目录、文件或者取消链接文件

  4.2.1 案例1-用file创建一个软连接/etc/fstab到/tmp/fstab

 1     [root@test-1 ansible]# ansible test -m file -a "src=/etc/fstab dest=/tmp/fstab  state=link"
 2     [DEPRECATION WARNING]: DEFAULT_SUDO_USER option, In favor of Ansible Become, which is a generic framework. See become_user. , use become instead. This feature will be 
 3     removed in version 2.8. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

  4.3 copy模块

1 backup:在覆盖之前将原文件备份,备份文件包含时间信息。有两个选项:yes|no 
2 content:用于替代"src",可以直接设定指定文件的值 
3 dest:必选项。要将源文件复制到的远程主机的绝对路径,如果源文件是一个目录,那么该路径也必须是个目录 
4 directory_mode:递归的设定目录的权限,默认为系统默认权限
5 force:如果目标主机包含该文件,但内容不同,如果设置为yes,则强制覆盖,如果为no,则只有当目标主机的目标位置不存在该文件时,才复制。默认为yes
6 others:所有的file模块里的选项都可以在这里使用
7 src:要复制到远程主机的文件在本地的地址,可以是绝对路径,也可以是相对路径。如果路径是一个目录,它将递归复制。在这种情况下,如果路径使用"/"来结尾,则只复制目录里的内容,如果没有使用"/"来结尾,则包含目录在内的整个内容全部复制,类似于rsync。 
8 validate :The validation command to run before copying into place. The path to the file to validate is passed in via '%s' which must be present as in the visudo example below.

  4.3.1 案例1-从本地拷贝文件到ansibel目标的目录

 1 [root@test-1 ansible]# touch /tmp/aa                                   #本地测试创建的aa文件

2 free_form:要执行的linux指令
3 chdir:在执行指令之前,先切换到该指定的目录
4 removes:一个文件名,当该文件不存在,则该选项不执行

 1 [root@test-1 ansible]# ansible-doc -s shell
 2 - name: Execute commands in nodes.
 3   shell:
 4       chdir:                 # 执行之前,先cd到指定目录在执行命令
 5       creates:               # 一个文件名,当这个文件存在,则该命令不执行
 6       executable:            # 切换shell来执行命令,需要使用命令的绝对路径
 7       free_form:             # (required) The shell module takes a free form command to run, as a string.  There's not an actual option named "free form".  See the
 8                                examples!
 9       removes:               # a filename, when it does not exist, this step will *not* be run.
10       stdin:                 # Set the stdin of the command directly to the specified value.
11       warn:                  # if command warnings are on in ansible.cfg, do not warn about this particular line if set to no/false.

4.6 service模块

      用于管理服务
      该模块包含如下选项

1 arguments:给命令行提供一些选项 
2 enabled:是否开机启动 yes|no
3 name:必选项,服务名称 
4 pattern:定义一个模式,如果通过status指令来查看服务的状态时,没有响应,就会通过ps指令在进程中根据该模式进行查找,如果匹配到,则认为该服务依然在运行
5 runlevel:运行级别
6 sleep:如果执行了restarted,在则stop和start之间沉睡几秒钟
7 state:对当前服务执行启动,停止、重启、重新加载等操作(started,stopped,restarted,reloaded)

 4.11 synchronize-模块

         使用rsync同步文件,其参数如下:

 1   archive: 归档,相当于同时开启recursive(递归)、links、perms、times、owner、group、-D选项都为yes ,默认该项为开启
 2   checksum: 跳过检测sum值,默认关闭
 3   compress:是否开启压缩
 4   copy_links:复制链接文件,默认为no ,注意后面还有一个links参数
 5   delete: 删除不存在的文件,默认no
 6   dest:目录路径
 7   dest_port:默认目录主机上的端口 ,默认是22,走的ssh协议
 8   dirs:传速目录不进行递归,默认为no,即进行目录递归
 9   rsync_opts:rsync参数部分(-avz)等参数
10   set_remote_user:主要用于/etc/ansible/hosts中定义或默认使用的用户与rsync使用的用户不同的情况
11   mode: push或pull 模块,push模的话,一般用于从本机向远程主机上传文件,pull 模式用于从远程主机上取文件
12   src:源目录路径
13   rsync_path:指定rsync的执行文件路径

 4.18 setup收集指定服务器的信息

        收集指定服务器的信息,每个被管理节点在接收并运行管理命令之前,会将自己主机相关信息,如操作系统版本、IP地址等报告给远程的ansbile主机.在playbooks里经常会用到的一个参数gather_facts就与该模块相关。setup模块下经常使用的一个参数是filter参数,具体使用示例如下:

 1 [root@test-1 scripts]# ansible-doc -s setup
 2 - name: Gathers facts about remote hosts
 3   setup:
 4       fact_path:             # path used for local ansible facts (`*.fact') - files in this dir will be run (if executable) and their results
 5                                be added to `ansible_local' facts if a file is not executable it is read. Check
 6                                notes for Windows options. (from 2.1 on) File/results format can be JSON or INI-
 7                                format. The default `fact_path' can be specified in `ansible.cfg' for when setup
 8                                is automatically called as part of `gather_facts'.
 9       filter:                # if supplied, only return facts that match this shell-style (fnmatch) wildcard.
10       gather_subset:         # if supplied, restrict the additional facts collected to the given subset. Possible values: `all', `min',
11                                `hardware', `network', `virtual', `ohai', and `facter'. Can specify a list of
12                                values to specify a larger subset. Values can also be used with an initial `!' to
13                                specify that that specific subset should not be collected.  For instance:
14                                `!hardware,!network,!virtual,!ohai,!facter'. If `!all' is specified then only the
15                                min subset is collected. To avoid collecting even the min subset, specify
16                                `!all,!min'. To collect only specific facts, use `!all,!min', and specify the
17                                particular fact subsets. Use the filter parameter if you do not want to display
18                                some collected facts.
19       gather_timeout:        # Set the default timeout in seconds for individual fact gathering

4.18.2 执行案例

1 ansible 10.212.52.252 -m setup -a 'filter=ansible_*_mb'   //查看主机内存信息
2 ansible 10.212.52.252 -m setup -a 'filter=ansible_eth[0-2]'   //查看地接口为eth0-2的网卡信息
3 ansible all -m setup --tree /tmp/facts   //将所有主机的信息输入到/tmp/facts目录下,每台主机的信息输入到主机名文件中(/etc/ansible/hosts里的主机名)

4.19  systemd模块

      用于管理服务
      该模块包含如下选项

1 daemon_reload:重新载入systemd
2 enabled:是否开机启动 yes|no
3 name:必选项,服务名称 
4 state:对当前服务执行启动,停止、重启、重新加载等操作(started,stopped,restarted,reloaded)

4.19.1 使用案例

1 ansible webservers -m systemd -a "deamon_reload=yes"     // 刷新服务
2 ansible webservers -m systemd -a "name=nginx enabled=yes state=started"   // 启动服务并开机启动
3 ansible webservers -m systemd -a "name=nginx enabled=no state=stopped"    // 停止服务 开机禁止启动
4 ansible webservers -m systemd -a "name=nginx state=restarted"            // 重启服务

4.20 hostname模块

功能:用于管理远程主机的主机名。

name: 必选项,主机名称

4.20.1 使用案例

[root@ansible ansible-kubeadm-install-k8s]# ansible 1.116.112.164   -m hostname -a 'name=k8s-master'
1.116.112.164 | SUCCESS => {
    "ansible_facts": {
        "ansible_domain": "", 
        "ansible_fqdn": "k8s-master", 
        "ansible_hostname": "k8s-master", 
        "ansible_nodename": "k8s-master", 
        "discovered_interpreter_python": "/usr/bin/python"
