ansible-doc

    -l    List available modules

    -s    Show playbook snippet for specified module(s)

ansible：

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

        args:

            key=value

            注意：command模块要执行命令无须为key=value格式，而是直接给出要执行的命令即可；

        常用模块：

            command

                -a 'COMMAND'

                #查看web组磁盘空间使用率

                ansible web -m command -a 'df -h'

            user

                -a 'name= state={present|absent} system= uid='

                #创建系统账户test，uid为444

                ansible test -m user -a 'name=test state=present system=yes uid=444'

                ansible test -m user -a 'name=test state=absent'

            group

                -a 'name= gid= state= system='

            cron

                -a 'name= minute= hour= day= month= weekday= job= user= state='

                #每3分钟做一次时间同步

                ansible test -m cron -a 'name="custom job" minute=*/3 job="/usr/sbin/ntpdate 172.16.254.23"'

                ansible test -m cron -a 'name="custom job" state=absent'

            copy

                -a 'dest= src= mode= owner= group='

                ansible test -m copy -a 'src=/root/a.sh dest=/tmp/ owner=root group=root mode=0755'

            file

                -a 'path= mode= owner= group= state={directory|link|present|absent} src='

                ansible test -m file -a 'path=/tmp/a.sh state=absent'

            ping

                ansible web -m ping

            yum

                -a 'name= state={present|latest|absent}'

                ansible test -m yum -a 'name=httpd state=latest'

                ansible test -m yum -a 'name=httpd state=absent'

            service

                -a 'name= state={started|stopped|restarted} enabled='

                ansible test -m service -a 'name=httpd state=started enabled=yes'

            shell

                -a 'COMMAND'

                ansible test -m shell -a 'chkconfig --list httpd'

            script

                -a '/path/to/script'

                ansible test -m script -a '/root/a.sh'

            setup

                ansible web -m setup

            synchronize

                -a 'src= dest= mode={pull|push} rsync_opts="auv"'

                ansible webg:webappg -m synchronize -a 'src=/app/webapps/app/  dest=/app/webapps/app/  mode=push  rsync_opts="-av"'
