1.05 Ansible远程执行脚本

 首先创建一个shell脚本
 vim  /tmp/test.sh  //加入内容
 #!/bin/bash
 echo `date` > /tmp/ansible_test.txt
 然后把该脚本分发到各个机器上
 ansible testhost -m copy -a "src=/tmp/test.sh dest=/tmp/test.sh mode=0755"
 最后是批量执行该shell脚本
 ansible testhost -m shell -a "/tmp/test.sh"
 shell模块,还支持远程执行命令并且带管道
 ansible testhost -m shell -a "cat /etc/passwd|wc -l "


[root@Dasoncheng ~]# ansible testhost -m copy -a 'src=/tmp/test.sh dest=/tmp/test.sh mode=755'

1.06 ansible管理任务计划

 ansible testhost -m cron -a "name='test cron' job='/bin/touch /tmp/1212.txt'  weekday=6"

 若要删除该cron 只需要加一个字段 state=absent 
 ansible testhost -m cron -a "name='test cron' state=absent"

 其他的时间表示:分钟 minute 小时 hour 日期 day 月份 month


[root@Dasoncheng ~]# ansible testhost -m cron -a "name='test_cron' job='/bin/touch /tmp/1212.txt' weekday=6"
127.0.0.1 | SUCCESS => {
    "changed": true, 
    "envs": [], 
    "jobs": [
        "test_cron"
    ]
}
192.168.60.12 | SUCCESS => {
    "changed": true, 
    "envs": [], 
    "jobs": [
        "test_cron"
    ]
}
cdn002 | SUCCESS => {
    "changed": true, 
    "envs": [], 
    "jobs": [
        "test_cron"
    ]
}
[root@Dasoncheng ~]# ansible cdn002 -m command -a 'crontab -l'
cdn002 | SUCCESS | rc=0 >>
#Ansible: test_cron
* * * * 6 /bin/touch /tmp/1212.txt

[root@Dasoncheng ~]# ansible cdn002 -m cron -a "name='test_cron' state=absent"
cdn002 | SUCCESS => {
    "changed": true, 
    "envs": [], 
    "jobs": []
}
[root@Dasoncheng ~]# ansible cdn002 -m command -a 'crontab -l'
cdn002 | SUCCESS | rc=0 >>

1.07 Ansible安装rpm包/管理服务

 ansible testhost -m yum -a "name=httpd" 
 在name后面还可以加上state=installed/removed
 ansible testhost -m service -a "name=httpd state=started enabled=yes" 
 这里的name是centos系统里的服务名,可以通过chkconfig --list查到。
 Ansible文档的使用
 ansible-doc -l   列出所有的模块
 ansible-doc cron  查看指定模块的文档


[root@Dasoncheng ~]# ansible cdn002 -m yum -a "name=httpd state=installed"
cdn002 | SUCCESS => {
    "changed": true, 
    "msg": "", 
    "rc": 0, 
    "results": 
……

[root@Dasoncheng ~]# ansible cdn002 -m service -a "name=httpd state=started enabled=yes"
cdn002 | SUCCESS => {
    "changed": true, 
    "enabled": true, 
    "name": "httpd", 
    "state": "started", 
    "status": {

[root@Dasoncheng ~]# ansible cdn002 -m command -a 'systemctl status httpd'

1.08 Ansible文档的使用

[root@Dasoncheng ~]# ansible-doc -l
a10_server                                           Manage A10 Networks AX/SoftAX/Thunder/vThund...
a10_server                                           Manage A10 Networks AX/SoftAX/Thunder/vThund...
a10_server_axapi3                                    Manage A10 Networks AX/SoftAX/Thunder/vThund...
[root@Dasoncheng ~]# ansible-doc cron
> CRON    (/usr/lib/python2.7/site-packages/ansible/modules/system/cron.py)

        Use this module to manage crontab and environment variables entries. This
        module allows you to create environment variables and named crontab
        entries, update, or delete them. When crontab jobs are managed: the
        module includes one line with the description of the crontab entry
        `"#Ansible: <name>"' corresponding to the "name" passed to the module,
        which is used by future ansible/module calls to find/check the state. The
        "name" parameter should be unique, and changing the "name" value will
        result in a new cron task being created (or a different one being
        removed). When environment variables are managed: no comment line is
        added, but, when the module needs to find/check the state, it uses the
        "name" parameter to find the environment variable definition line. When
        using symbols such as %, they must be properly escaped.

OPTIONS (= is mandatory):

- backup
        If set, create a backup of the crontab before it is modified. The
        location of the backup is returned in the `backup_file' variable by this
        module.
        [Default: no]
        type: bool

- cron_file
        If specified, uses this file instead of an individual user's crontab. If
        this is a relative path, it is interpreted with respect to /etc/cron.d.
        (If it is absolute, it will typically be /etc/crontab). Many linux
        distros expect (and some require) the filename portion to consist solely
        of upper- and lower-case letters, digits, underscores, and hyphens. To
        use the `cron_file' parameter you must specify the `user' as well.
        [Default: (null)]
