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

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

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。
