注:-a参数后的命令用单引号,单引号,单引号;双引号有可能会出问题,特别是在user模块;

模块一:测试目标主机是否在线:ping模块

主机如果在线,则回复pong

1 2 3 4 5 6 7 8 9 10

测试主机是否在线 [root@localhost ~]# ansible erp -m ping 192.168.10.6 | SUCCESS => { "changed": false, "ping": "pong" } 192.168.10.7 | SUCCESS => { "changed": false, "ping": "pong" }

模块二:command模块和shell

作用:用于在各被管理节点运行指定的命令

shell和command的区别:shell模块可以特殊字符,而command是不支持

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

显示各节点的日期 [root@localhost ~]# ansible erp -m command -a 'date' 192.168.10.6 | SUCCESS | rc=0 >> Tue Feb 7 09:20:35 CST 2017 192.168.10.7 | SUCCESS | rc=0 >> Tue Feb 7 09:20:35 CST 2017 删除各节点的/tmp/test目录 [root@localhost ~]# ansible erp -m command -a 'mkdir /tmp/test' 192.168.10.10 | SUCCESS | rc=0 >> 192.168.10.6 | SUCCESS | rc=0 >> [root@localhost ~]# ansible erp -m shell -a 'rm -rf /tmp/test' 192.168.10.6 | SUCCESS | rc=0 >> 192.168.10.10 | SUCCESS | rc=0 >>

模块三:user模块:管理用户的模块

模块参数详解:

name:指定用户名

password:设定用户密码,password参数需要接受md5加密后的值

state:用户状态,默认为present

present:表示添加用户

absent:表示删除用户

update_password:修改用户密码

always:新密码和旧密码不同时进行修改

on_create:为新创建的用户指定密码

createhome:创建家目录

yes:默认项,即创建用户默认是有家目录的

no:创建用户时不创建家目录

remove:

yes:删除用户家目录,需要指定此参数

no:默认项,删除用户时默认不删除用户的家目录

system:

yes:默认创建为普通用户,而非系统用户

如果不指定默认生成的选项有:

home:创建家目录

shell:创建默认的shell为/bin/bash

system:默认创建为普通用户,而非系统用户,指定是用yes

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79

这些收集的信息,可以作为变量。

1

[root@localhost tmp]# ansible erp -m setup

模块九:安装模块:yum

模块参数详解:

name:表示要安装软件包的名字,默认最新的程序包,指明要安装的程序包,可以带上版本号

state:表示是安装还卸载

present:默认的,表示为安装

lastest:安装为最新的版本

absent:表示删除

模块十:服务模块:service

模块参数详解:

enabled:表示设置服务开机是否启动,取值为true或者false;enabled=yes

name=:表示要控制哪一个服务

state:

started:表示现在就启动此服务

stopped:表示现在关闭此服务

restarted:表示重启此服务

sleep:如果执行了restarted,在stop和start之间沉睡几秒

arguments:表示向命令行传递的参数

1

[root@localhost tmp]#ansible erp -m service -a 'enabled=on name=httpd state=started'

模块十一:文件编辑模块:lineinfile

模块参数详解:

path:指定要修改的配置文件

regexp:匹配要修改的内容

line:要增加或者修改的内容

state:

absent:表示删除,当匹配到时进行删除

present:表示增加,当匹配到时进行修改,当没有匹配到时在最后增加一行,默认为此项

backrefs:

no:表示如果没有匹配到,则增加line;如果匹配成功,则替换line;

yes:表示如果没有匹配到,则不变line;如果匹配成功,则替换line;

backup:

no:表示如果没有匹配到,则增加line;如果匹配成功,则替换line;不备份原文件

yes:表示如果没有匹配到,则增加line;如果匹配成功,则替换line;备份原文件

insertafter(匹配的是此行):

在匹配到的行之后添加一行

insertbefore(匹配的是此行):

在匹配到的行之前添加一行

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

修改nginx.conf测试: [root@nfs-server playbook]# cat modify_nginx.yml --- - hosts: 192.168.2.111 tasks: - name: "修改配置文件" lineinfile: dest: "/etc/nginx/conf.d/default.conf" regexp: 'listen 80;' line: ' listen 8000;' #backup: yes backrefs: yes notify: - reload nginx handlers: - name: reload nginx service: name=nginx state=reloaded

注:经测试,当不添加backerfs: yes参数时,匹配到后也会进行替换,但当匹配到的内容不存在时,会在最后增加一行;所以当不增加backerfs参数时,要确定匹配到的内容存在;

替换存在的行:

1

#ansible oms -m lineinfile -a 'path=/etc/sudoers regexp="SYSTEM,SOFTWARE" line="STAPLES_ADMIN ALL=(ROOT) NOPASSWD:NETWORKING,LOCATE,STORAGE,DELEGATING,DRIVERS,SYSTEM,SOFTWARE,SERVICES,PROCESSES,FILE" backrefs=no'

匹配到的行后增加一行:

1

#ansible oms -m lineinfile -a 'dest=/etc/sudoers insertafter="Cmnd_Alias SYSTEM = /usr/sbin/reboot, /usr/sbin/halt, /usr/bin/ansible, /usr/bin/ssh" line="Cmnd_Alias FILE = /bin/mkdir,/bin/touch,/usr/bin/vim"'

删除匹配到的行:

1

#ansible oms -m lineinfile -a 'path=/etc/sudoers state=absent regexp="PROCESSES,FILE"'
