Ansible基本模块使用

共计 5053 个字符，预计需要花费 13 分钟才能阅读完成。

使用ad-hoc方式记录下一些基础模块使用

命令模块

command

注意：Ad-hoc默认使用该模块command(不支持管道重定向等符号)

[root@manager ~]# ansible nfs -m command -a 'w'
nfs01 | CHANGED | rc=0 >>
 02:51:03 up  2:22,  2 users,  load average: 0.00, 0.01, 0.05
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    10.0.0.1         00:29    2:00m  0.21s  0.21s -bash
root     pts/1    172.16.1.61      02:51    0.00s  0.12s  0.00s w

shell

注意：比command高级，可支持管道重定向等符号，但遇到$会被解析

[root@manager ~]# ansible nfs -m shell -a "hostname -I | awk '{print $1}'"
nfs01 | CHANGED | rc=0 >>
10.0.0.31 172.16.1.31 192.168.154.155 

[root@manager ~]# ansible nfs -m shell -a "hostname -I | awk '{print \$1}'"
nfs01 | CHANGED | rc=0 >>
10.0.0.31

用户和组模块

user

创建不可登录用户

[root@manager ~]# ansible nfs -m user -a "name=aaa uid=888 group=www append=yes create_home=no shell=/sbin/nologin"

    "changed": true, 
    "comment": "", 
    "create_home": false, 
    "group": 666, 
    "home": "/home/aaa",

服务操作模块

service&systemd

开启服务

# centos 6.x
[root@manager ~]# ansible nfs -m service -a 'name=nfs-server state=started'

# centos 7.x
[root@manager ~]# ansible nfs -m systemd -a 'name=nfs-server state=started'

停止服务

# centos 6.x
[root@manager ~]# ansible nfs -m service -a 'name=nfs-server state=stoped'

# centos 7.x
[root@manager ~]# ansible nfs -m systemd -a 'name=nfs-server state=stoped'

重启服务

# centos 6.x
[root@manager ~]# ansible nfs -m service -a 'name=nfs-server state=restarted'

# centos 7.x
[root@manager ~]# ansible nfs -m systemd -a 'name=nfs-server state=restarted'

systemd服务配置reload

# centos 7.x
[root@manager ~]# ansible nfs -m systemd -a 'name=crond state=restarted daemon_reload=yes'

[root@manager ~]# ansible nfs -m systemd -a 'daemon_reload=yes'

mount

[root@manager ~]# ansible web -m mount -a "src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=present"
[root@manager ~]# ansible web -m mount -a "src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=mounted"
[root@manager ~]# ansible web -m mount -a "src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=unmounted"
[root@manager ~]# ansible web -m mount -a "src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=absent"

cron

注意：创建定时同步时间任务，名字必须指定，ansible是根据名字来处理定时任务的增删改的

创建定时任务

[root@manager ~]# ansible nfs -m cron -a 'name="sync time" minute=00 hour=00 weekday=1 job="ntpdate ntp.api.bz &>/dev/null" state=present'
nfs01 | CHANGED => {
    "changed": true, 
    "envs": [], 
    "jobs": [
        "sync time"
    ]
}

# 在客户端节点上查看
[root@nfs ~]# crontab -l
#Ansible: sync time
00 00 * * 1 ntpdate ntp.api.bz &>/dev/null

删除定时任务

[root@manager ~]# ansible nfs -m cron -a 'name="sync time" state=absent'
nfs01 | CHANGED => {
    "changed": true, 
    "envs": [], 
    "jobs": []
}

yum

[root@manager ~]# ansible nfs -m yum -a 'name=nfs-utils state=installed'
nfs01 | SUCCESS => {
    "ansible_facts": {
        "pkg_mgr": "yum"
    }, 
    "changed": false, 
    "msg": "", 
    "rc": 0, 
    "results": [
        "1:nfs-utils-1.3.0-0.61.el7.x86_64 providing nfs-utils is already installed"
    ]
}
