使用Salt States在Minion上配置LAMP堆栈

打开/etc/salt/base/top.sls文件并添加其他行：
/etc/salt/base/top.sls
base:
  '*':
     - lamp
     - extras
     - lampconf            

创建和编辑/etc/salt/base/lampconf.sls文件：
/etc/apache2/apache2.conf-KA:
  file.replace:
    - name: /etc/apache2/apache2.conf
    - pattern: 'KeepAlive On'
    - repl: 'KeepAlive Off'
    - show_changes: True

/etc/apache2/apache2.conf-IM:
  file.append:
    - name: /etc/apache2/apache2.conf
    - text: |
        <IfModule mpm_prefork_module>
        StartServers 4
        MinSpareServers 20
        MaxSpareServers 40
        MaxClients 200
        MaxRequestsPerChild 4500
        </IfModule>

将状态设置传输到 Minions：

salt '*' state.highstate

禁用单个 Minion 或所有 Minions 上的默认 Apache 虚拟主机：
对于特定的 Minion ：

salt '<hostname or Minion ID>' cmd.run "a2dissite *default"
对于所有的 Minion ：

salt '*' cmd.run "a2dissite *default"

为网站的文件、日志和备份创建目录。替换example.com为网站名称：

salt '<hostname or Minion ID>' file.makedirs /var/www/example.com/pubic_html/ salt '<hostname or Minion ID>' file.makedirs /var/www/example.com/log/ salt '<hostname or Minion ID>' file.makedirs /var/www/example.com/backups/

在 Master 分支上创建一个目录以保存所有 Minion 虚拟主机文件。该目录可以作为所有 Minion 网站的索引。

mkdir /etc/salt/base/minionsites

/etc/salt/base/minionsites/example.com.conf为指定的 Minion 创建 vhost 文件。
全部替换example.com以及以下命令。
# domain: example.com
# public: /var/www/example.com/public_html/

<VirtualHost *:80>
  # Admin email, Server Name (domain name), and any aliases
  ServerAdmin webmaster@example.com
  ServerName  www.example.com
  ServerAlias example.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.html index.php
  DocumentRoot /var/www/example.com/public_html
  # Log file locations
  LogLevel warn
  ErrorLog  /var/www/example.com/log/error.log
  CustomLog /var/www/example.com/log/access.log combined
</VirtualHost>

将 vhost 文件从 Master 复制到/sites-availableMinion 的目录：

salt-cp '<hostname or Minion ID>' /etc/salt/base/minionsites/example.com.conf /etc/apache2/sites-available/example.com.conf

启用新网站并重新启动 Apache：

salt '<hostname or Minion ID>' cmd.run "a2ensite example.com.conf" salt '<hostname or Minion ID>' cmd.run "service apache2 reload"
