1，查看使用帮助
ansible-doc -l =============>相当于Linux里面的命令
查模块的参数
ansible-doc -s ==========>>接模块名查看模块参数信息
===================>查模块信息就相当于查Linux里面的命令，模块就是ansible里的命令
2，command模块知识
=======================================================
参数 chdir=/tmp 配置相当于cd /tmp
[root@BOSS ~]# ansible oldboy -m command -a "pwd chdir=/etc"
172.16.1.31 | CHANGED | rc=0 >>
/etc
172.16.1.41 | CHANGED | rc=0 >>
/etc
=======================================================
参数 creates=/etc 相当于条件测试
[root@BOSS ~]# ansible oldboy -m command -a "pwd creates=/etc"
172.16.1.31 | SUCCESS | rc=0 >>
skipped, since /etc exists
172.16.1.41 | SUCCESS | rc=0 >>
skipped, since /etc exists
==============================================================
参数 removes=/root 相当于条件测试
[root@BOSS ~]# ansible oldboy -m command -a "ls /root removes=/etc"
172.16.1.41 | CHANGED | rc=0 >>
(date +%F %T).tar.gz
(date +%F).tar.gz
===================================>>省略若干
参数 warn=False 忽略警告
[root@BOSS ~]# ansible oldboy -m command -a "chmod 000 /etc/hosts"
[WARNING]: Consider using the file module with mode rather than running 'chmod'. 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.
172.16.1.41 | CHANGED | rc=0 >>
172.16.1.31 | CHANGED | rc=0 >> ======================>>会出现警告
[root@BOSS ~]# ansible oldboy -m command -a "chmod 000 /etc/hosts warn=False"
172.16.1.41 | CHANGED | rc=0 >>
172.16.1.31 | CHANGED | rc=0 >>===============>>>不出现警告
[root@BOSS ~]# ansible oldboy -m command -a "ls -la /etc/hosts"
172.16.1.41 | CHANGED | rc=0 >>

sh: /server/scripts/bak.sh: No such file or directorynon-zero return code
172.16.1.31 | CHANGED | rc=0 >>
++ date +%F
+ /bin/cp /etc/hosts /opt/hosts_2019-04-24
===========================================>>>远程执行脚本条件是必须存在
[root@NFS /server/scripts]# scp bak.sh 172.16.1.41:/server/scripts
------------------------------------------------------->>>使用scp拷贝
[root@BOSS ~]# ansible oldboy -m shell -a "sh -x /server/scripts/bak.sh"
