ansible常用module

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"'
