Puppet部署Nginx返代示例

一、创建目录并编辑Nginx安装模块

mkdir -pv /etc/puppet/modules/nginx/{manifests,files,templates,spec,tests,lib}

]# vim nginx/manifests/init.pp
class nginx {
    package{'nginx':
        ensure => latest
    } ->
    service{'nginx':
        ensure => running,
        enable => true
    }
}

二、编辑Nginx配置文件

]# vim nginx/manifests/web.pp
class nginx::web($port=)  inherits nginx {
    file{'web.conf':
        path   => '/etc/nginx/conf.d/web.conf',
        content => template('nginx/web.conf.erb')
    }
    file{'/ngxdata/html':
        ensure  => directory
    }
    file{'index.html':
        ensure => file,
        path   => '/ngxdata/html/index.html',
        source => 'puppet:///modules/nginx/index.html',
        require => File['/ngxdata/html']
    }
    Service['nginx'] {
        subscribe  => File['web.conf']
    }
}

三、编辑反向代理配置

]# vim nginx/manifests/proxy.pp
class nginx::proxy($proxy_port=)  inherits nginx {
    file{'proxy.conf':
        path   => '/etc/nginx/conf.d/proxy.conf',
        content => template('nginx/proxy.conf.erb'),
    }
    Service['nginx'] {
        subscribe  => File['proxy.conf']
    }
}

四、配置模板与页面测试文件

]# vim nginx/templates/web.conf.erb
server {
    listen <%= @port %>;
    server_name <%= @fqdn %>;
    location /
        root /ngxdata/html;
    }
}

]# vim nginx/files/index.html
<h1> Nginx ok </h1>

]# vim nginx/templates/proxy.conf.erb
server {
    listen  <%= @proxy_port %>;
    server_name <%= @fqdn %>;
    location / {
        proxy_pass http://xxx.xxx.xxx:8080/;
    }
}

五、应用

]# puppet apply -v -e 'include nginx::proxy'

查看模板是否成效：

]# cat /etc/nginx/conf.d/proxy.conf
server {
    listen  ;
    server_name node1.danran.com;
    location / {
        proxy_pass http://xxx.xxx.xxx:8080/;
    }
}
