2015年底270多个模块，2016年达到540个，2018年01月12日有1378个模块，2018年07月15日1852个模块,2019年05月25日（ansible 2.7.10）时2080个模块，2020年03月02日有3387个模块
虽然模块众多，但最常用的模块也就2，30个而已，针对特定业务只用10几个模块
文档参考：
Command模块
功能：在远程主机执行命令，此为默认模块，可忽略-m选项
注意：此命令不支持 $VARNAME < > | ; & 等，用shell模块实现
例：
[root@ansible ~] ansible websrvs -m command -a 'chdir=/etc cat centos-release'
10.0.0.7 | CHANGED | rc=0 >>
CentOS Linux release 7.7.1908 (Core)
10.0.0.8 | CHANGED | rc=0 >>
CentOS Linux release 8.1.1911 (Core)
[root@ansible ~] ansible websrvs -m command -a 'chdir=/etc creates=/data/f1.txt cat centos-release'
10.0.0.7 | CHANGED | rc=0 >>
CentOS Linux release 7.7.1908 (Core)
10.0.0.8 | SUCCESS | rc=0 >>
skipped, since /data/f1.txt exists
[root@ansible ~] ansible websrvs -m command -a 'chdir=/etc removes=/data/f1.txt cat centos-release'
10.0.0.7 | SUCCESS | rc=0 >>
skipped, since /data/f1.txt does not exist
10.0.0.8 | CHANGED | rc=0 >>
CentOS Linux release 8.1.1911 (Core)
ansible srvs -m command -a ‘service vsftpd start’
ansible srvs -m command -a ‘echo magedu |passwd --stdin wang’
ansible websrvs -m command -a 'rm -rf /data/'
Shell模块
功能：和command相似，用shell执行命令
例：
[root@ansible ~] ansible websrvs -m shell -a "echo $HOSTNAME"
10.0.0.7 | CHANGED | rc=0 >>
ansible
10.0.0.8 | CHANGED | rc=0 >>
ansible
[root@ansible ~] ansible websrvs -m shell -a 'echo $HOSTNAME'
10.0.0.7 | CHANGED | rc=0 >>
centos7.wangxiaochun.com
10.0.0.8 | CHANGED | rc=0 >>
centos8.localdomain
[root@ansible ~] ansible websrvs -m shell -a 'echo centos | passwd --stdin wang'
10.0.0.7 | CHANGED | rc=0 >>
Changing password for user wang.
passwd: all authentication tokens updated successfully.
10.0.0.8 | CHANGED | rc=0 >>
Changing password for user wang.
passwd: all authentication tokens updated successfully.
[root@ansible ~] ansible websrvs -m shell -a 'ls -l /etc/shadow'
10.0.0.7 | CHANGED | rc=0 >>
---------- 1 root root 889 Mar 2 14:34 /etc/shadow
10.0.0.8 | CHANGED | rc=0 >>
---------- 1 root root 944 Mar 2 14:34 /etc/shadow
[root@ansible ~] ansible websrvs -m shell -a 'echo hello > /data/hello.log'
10.0.0.7 | CHANGED | rc=0 >>
10.0.0.8 | CHANGED | rc=0 >>
[root@ansible ~] ansible websrvs -m shell -a 'cat /data/hello.log'
10.0.0.7 | CHANGED | rc=0 >>
hello
10.0.0.8 | CHANGED | rc=0 >>
hello
将shell模块代替command模块，设为默认模块
[root@ansible ~] vim /etc/ansible/ansible.cfg
#修改下面一行
module_name = shell
Script模块
功能：在远程主机上运行anisble服务器上的脚本
例：
ansible websrvs -m script -a /data/test.sh
Copy模块
功能：从anidble的主控端复制文件到远程主机
例：
#如目标存在，默认覆盖，此处指定先备份
ansible srv -m copy -a “src=/root/test1.sh dest=/tmp/test2.sh owner=wang
mode=600 backup=yes”
#指定内容，直接生成目标文件
ansible websrvs -m copy -a "content='test line1\ntest line2' dest=/tmp/test.txt"
#复制/etc/下的文件，不包括/etc/目录自身
ansible srv -m copy -a “src=/etc/ dest=/backup”
Fetch模块
功能：从远程主机提取文件至anidble主控端，与copy相反，目前不支持目录
例：
ansible srv -m fetch -a ‘src=/root/test.sh dest=/data/scripts’
[root@ansible ~] ansible all -m fetch -a 'src=/etc/redhat-release
dest=/data/os'
[root@ansible ~] tree /data/os/
/data/os/
├── 10.0.0.6
│ └── etc
│ └── redhat-release
├── 10.0.0.7
│ └── etc
│ └── redhat-release
└── 10.0.0.8
└── etc
└── redhat-release
6 directories, 3 files
File模块
功能：设置文件属性
例：
#创建空文件
ansible srv -m file -a 'path=/data/test.txt state=touch'
ansible srv -m file -a 'path=/data/test.txt state=absent'
ansible srv -m file -a "path=/root/test.sh owner=wang mode=755“
#创建目录
ansible srv -m file -a 'path=/data/mysql state=directory owner=mysql
group=mysql'
#创建软链接
ansible srv -m file -a 'src=/data/testfile dest=/data/testfile-link state=link'
Unarchive模块
功能：解包解压缩
实现有两种用法：
1、将ansible主机上的压缩包传到远程主机后解压缩至特定目录，设置copy=yes
2、将远程主机上的某个压缩包解压缩到指定路径下，设置copy=no
常见参数：
copy：默认为yes，当copy=yes，拷贝的文件是从ansible主机复制到远程主机上，如果设置为copy=no，会在远程主机上寻找src源文件
remote_src：和copy功能一样且互斥，yes表示在远程主机，不在ansible主机，no表示文件在ansible主机上
src：源路径，可以是ansible主机上的路径，也可以是远程主机上的路径，如果是远程主机上的路径，则需要设置copy=no
dest：远程主机上的目标路径
mode：设置解压缩后的文件权限
例：
ansible srv -m unarchive -a 'src=/data/foo.tgz dest=/var/lib/foo'
ansible srv -m unarchive -a 'src=/tmp/foo.zip dest=/data copy=no mode=0777'
ansible srv -m unarchive -a 'src=https://example.com/example.zip dest=/data
copy=no'
Archive模块
功能：打包压缩
例：
ansible websrvs -m archive -a 'path=/var/log/ dest=/data/log.tar.bz2 format=bz2 owner=wang mode=0600'
Hostname模块
功能：管理主机名
例：
ansible node1 -m hostname -a “name=websrv”
ansible 192.168.100.18 -m hostname -a 'name=node18.magedu.com'
Cron模块
功能：计划任务
支持时间：minute，hour，day，month，weekday
例:
#备份数据库脚本
[root@centos8 ~] cat mysql_backup.sh
mysqldump -A -F --single-transaction --master-data=2 -q -uroot |gzip >
/data/mysql_`date +%F_%T`.sql.gz
#创建任务
ansible 10.0.0.8 -m cron -a 'hour=2 minute=30 weekday=1-5 name="backup mysql"
job=/root/mysql_backup.sh'
ansible srv -m cron -a "minute=*/5 job='/usr/sbin/ntpdate 172.20.0.1
&>/dev/null' name=Synctime"
#禁用计划任务
ansible srv -m cron -a "minute=*/5 job='/usr/sbin/ntpdate 172.20.0.1
&>/dev/null' name=Synctime disabled=yes"
#启用计划任务
ansible srv -m cron -a "minute=*/5 job='/usr/sbin/ntpdate 172.20.0.1
&>/dev/null' name=Synctime disabled=no"
#删除任务
ansible srv -m cron -a "name='backup mysql' state=absent"
ansible srv -m cron -a 'state=absent name=Synctime'
Yum模块
功能：管理软件包，只支持RHEL，CentOS，fedora，不支持Ubuntu其它版本
例：
ansible srv -m yum -a ‘name=httpd state=present’ #安装
ansible srv -m yum -a ‘name=httpd state=absent’ #删除
Service模块
功能：管理服务
例：
ansible srv -m service -a 'name=httpd state=started enabled=yes'
ansible srv -m service -a 'name=httpd state=stopped'
ansible srv -m service -a 'name=httpd state=reloaded’
ansible srv -m shell -a 'sed -i 's/^Listen 80/Listen 8080/'
/etc/httpd/conf/httpd.conf'
ansible srv -m service -a 'name=httpd state=restarted'
User模块
功能：管理用户
例：
#创建用户
ansible srv -m user -a 'name=user1 comment=“test user” uid=2048 home=/app/user1 group=root'
ansible srv -m user -a 'name=nginx comment=nginx uid=88 group=nginx
groups="root,daemon" shell=/sbin/nologin system=yes create_home=no
home=/data/nginx non_unique=yes'
#删除用户及家目录等数据
ansible srv -m user -a 'name=nginx state=absent remove=yes'
Group模块
功能：管理组
例：
#创建组
ansible websrvs -m group -a 'name=nginx gid=88 system=yes'
#删除组
ansible websrvs -m group -a 'name=nginx state=absent'
Lineinfile模块
ansible在使用sed进行替换时，经常会遇到需要转义的问题，而且ansible在遇到特殊符号进行替换时，
存在问题，无法正常进行替换 。其实在ansible自身提供了两个模块：lineinfile模块和replace模块，可
以方便的进行替换
功能：相当于set，可修改文件
例：
ansible all -m lineinfile -a "path=/etc/selinux/config regexp='^SELINUX='
line='SELINUX=enforcing'"
ansible all -m lineinfile -a 'dest=/etc/fstab state=absent regexp="^#"'
Replace模块
功能：该模块有点类似于sed命令，主要也是基于正则进行匹配和替换
例：
ansible all -m replace -a "path=/etc/fstab regexp='^(UUID.*)' replace='#\1'"
ansible all -m replace -a "path=/etc/fstab regexp='^#(.*)' replace='\1'"
Setup模块
功能： setup 模块来收集主机的系统信息，这些 facts 信息可以直接以变量的形式使用，但是如果主机较多，会影响执行速度，可以使用 gather_facts: no 来禁止 Ansible 收集 facts 信息
例：
ansible srv -m setup
ansible srv -m setup -a "filter=ansible_nodename"
ansible srv -m setup -a "filter=ansible_hostname"
ansible srv -m setup -a "filter=ansible_domain"
ansible srv -m setup -a "filter=ansible_memtotal_mb"
ansible srv -m setup -a "filter=ansible_memory_mb"
ansible srv -m setup -a "filter=ansible_memfree_mb"
ansible srv -m setup -a "filter=ansible_os_family"
ansible srv -m setup -a "filter=ansible_distribution_major_version"
ansible srv -m setup -a "filter=ansible_distribution_version"
ansible srv -m setup -a "filter=ansible_processor_vcpus"
ansible srv -m setup -a "filter=ansible_all_ipv4_addresses"
ansible srv -m setup -a "filter=ansible_architecture"
ansible srv -m setup -a "filter=ansible_processor*"
[root@ansible ~] ansible all -m setup -a 'filter=ansible_python_version'
