概要

之前做过 apache + passenger 作为 puppetmaster 前端的实验,

这次试试由 nginx + passenger 来作为 puppetmaster 的前端.

nginx + passenger 配置

package 安装

虽然debian 上有 puppetmaster-passenger 这个包, 但是它是针对 apache 服务器的,

安装这个包会顺带把 apache 也安装上, 然后passenger的配置都是在 apache 中.

所以, 我们通过 gem 的方式来安装 passenger,

root@master-2:~# gem install rake rack passenger --no-rdoc --no-ri
Successfully installed rake-10.4.2
Successfully installed rack-1.6.0
Fetching: passenger-4.0.57.gem (100%)
Building native extensions.  This could take a while...
Successfully installed passenger-4.0.57
3 gems installed

安装完成之后, nginx 不能直接从 apt-get 的源来安装, 但是可以用下面的命令来安装,

这样安装的 nginx 中就包含了 passenger 模块.

root@master-2:~# passenger-install-nginx-module
# 根据提示完成安装, 中途可能会提示用 apt-get 安装一些缺失的包.
# 安装完缺失的包后, 再次执行 passenger-install-nginx-module 即可.
# 安装 nginx 之前, 会有如下选择
Do you want this installer to download, compile and install Nginx for you?

 1. Yes: download, compile and install Nginx for me. (recommended)
    The easiest way to get started. A stock Nginx 1.6.2 with Passenger
    support, but with no other additional third party modules, will be
    installed for you to a directory of your choice.

 2. No: I want to customize my Nginx installation. (for advanced users)
    Choose this if you want to compile Nginx with more third party modules
    besides Passenger, or if you need to pass additional options to Nginx's
    'configure' script. This installer will  1) ask you for the location of
    the Nginx source code,  2) run the 'configure' script according to your
    instructions, and  3) run 'make install'.

Whichever you choose, if you already have an existing Nginx configuration file,
then it will be preserved.

Enter your choice (1 or 2) or press Ctrl-C to abort: 1

# 根据情况, 如果熟悉的话, 可以选择2, 否则选择1 即可自动编译安装 nginx

配置文件设置

nginx 配置文件 nginx.conf

root@master-1:~# cat /opt/nginx/conf/nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    passenger_root /var/lib/gems/1.9.1/gems/passenger-4.0.57;
    passenger_ruby /usr/bin/ruby1.9.1;

    include       mime.types;
    default_type  application/octet-stream;

    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
}

  access_log                 /var/log/nginx/puppet_access.log;
  error_log                  /var/log/nginx/puppet_error.log;

  root                       /usr/share/puppet/rack/puppetmasterd/public;
