创建state文件1

root@ubuntu:/etc/salt# vim master

找到下面的内容并解除注释:

file_roots:  base:
    - /srv/salt

然后杀死salt-master,并重启:salt-master -d.

root@ubuntu:/etc/salt# mkdir  /srv/salt
root@ubuntu:/etc/salt#cd /srv/salt
root@ubuntu:/srv/salt# vim top.sls

写入下面的代码:

base:  'os:ubuntu':    - match: grain    - webserver

创建sls文件
也是在这个目录下创建webserver.sls,包含下面内容:

apache2:                # ID declaration
  pkg:                  # state declaration
    - installed          #  function declaration

注意: The package name for the Apache httpd web server may differ depending on OS or distro — for example, on Fedora it ishttpd
but on Debian/Ubuntu it isapache2
.
第一行的apache这是任意定义的,只是定义要被安装的包的名字
第二行定义的是我们要用的stalt states,我们用了 pkg state来确保包被安装
第三行称为函数声明,定义了pkg状态模块中调用的函数

在所有的minions上安装apache,执行以下命令:

salt '*' state.apply

由于我的salt里面没有state.apply,我使用了state.highstate代替,我将上面的webserver.sls中的apache2改成了nginx:

nginx:           
  pkg:                 
    - installed

**Install the package**

root@ubuntu:/srv/salt# salt ubuntu1 state.highstate

----------
    State: - pkg
    Name:      nginx
    Function:  installed
        Result:    True
        Comment:   The following packages were installed/updated: nginx.

要是出错了,minions可以用下面的命令排查错误:

root@ubuntu1:~# salt-minion  -l debug
[DEBUG   ] Reading configuration from /etc/salt/minion
[DEBUG   ] loading log_handlers in ['/var/cache/salt/minion/extmods/log_handlers', '/usr/lib/python2.7/dist-packages/salt/log/handlers']
[DEBUG   ] Skipping /var/cache/salt/minion/extmods/log_handlers, it is not a directory
[DEBUG   ] Configuration file path: /etc/salt/minion
[INFO    ] Setting up the Salt Minion "ubuntu1"
[DEBUG   ] Created pidfile: /var/run/salt-minion.pid
[DEBUG   ] Chowned pidfile: /var/run/salt-minion.pid to user: root
.....

总结下:
首先vim /etc/salt/master,找到file_roots:行 并打开与之相关的注释,如:file_roots:
base: #这个是全局的

- /srv/salt           
   #还可以继续往下面加,如下:

dev:
– /srv/salt/dev
然后重启master.

第二,cd /srv/salt,创建top.sls文件,内容包括要调用的state模块,如下:

  'ubuntu1':
    - foobarcom

第三,创建webserver.sls状态文件,我们以安装apache为例:

apache2:
  pkg.installed: []
  service.running:
    - require:
      - pkg: apache2

执行命令:salt ubuntu1 state.highstate

ubuntu1:
----------
    State: - pkg
    Name:      apache2
    Function:  installed
        Result:    True
        Comment:   Package apache2 is already installed
        Changes:   
----------
    State: - service
    Name:      apache2
    Function:  running
        Result:    True
        Comment:   The service apache2 is already running
        Changes:   

Summary
------------
Succeeded: 2
Failed:    0
------------
Total:     2

如果有dev下有多个状态文件,可以base下面的top.sls文件中加载状态文件。
