CentOS6.5使用Nginx+Passenger部署Ruby on Rails环境

本文介绍如何使用Nginx+Passenger来部署Ruby on Rails环境，本文使用的操作系统版本是CentOS6.5。 1.安装ruby

  wget http://cache.ruby-lang.org/pub/ruby/ruby-2.0.0-p594.tar.gz   mkdir -p /data/app_platform/ruby   tar -zxvf ruby-2.0.0-p594.tar.gz   cd ruby-2.0.0-p594   ./configure --prefix=/data/app_platform/ruby   make   make install   ln -sf /data/app_platform/ruby/bin/* /usr/bin/   gem install rails 2.安装Nginx和Passenger Passenger有两种方式安装，一种是standalone 方式即Passenger独立运行，然后通过Nginx将ruby相关请求转发到Passenger，另一种是与Nginx整合在一起安装，维护方便。这里选用第一种方式。 Passenger 4.0以上和Nginx 1.4以上可以整合到一起

  wget http://s3.amazonaws.com/phusion-passenger/releases/passenger-4.0.57.tar.gz   wget http://nginx.org/download/nginx-1.4.4.tar.gz   useradd -r www -s /sbin/nologin   mkdir -p /data/app_platform/{nginx,passenger}   tar -zxvf passenger-4.0.57.tar.gz   mv -f passenger-4.0.57/*  /data/app_platform/passenger   tar -zxvf nginx-1.4.4.tar.gz   cd nginx-1.4.4   ./configure --user=www --group=www --prefix=/data/app_platform/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre  --with-http_perl_module --with-http_realip_module  --with-http_addition_module  --add-module=/data/app_platform/passenger/ext/nginx   make   make install            mkdir -p /data/app_platform/nginx/conf/conf.d/ 3.配置Nginx

添加Nginx启动文件/etc/init.d/nginx #!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig:  - 85 15 # description:  Nginx is an HTTP(S) server, HTTP(S) reverse \ #              proxy and IMAP/POP3 proxy server # processname: nginx # config:      /etc/nginx/nginx.conf # config:      /etc/sysconfig/nginx # pidfile:    /var/run/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.

Nginx主配置文件/data/app_platform/nginx/conf/nginx.conf user  www; worker_processes  4; error_log  /data/app_data/nginx/logs/error.log  error; pid        /data/app_data/nginx/logs/nginx.pid; worker_rlimit_nofile 65535; events {     use epoll;     worker_connections  10240; } http {     passenger_root /data/app_platform/passenger;     passenger_ruby /usr/bin/ruby;     passenger_max_pool_size 10;     passenger_debug_log_file /data/app_data/nginx/logs/passenger.log;     passenger_show_version_in_header on;     passenger_spawn_method smart;     include      mime.types;     default_type  application/octet-stream;     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '                       '$status $body_bytes_sent "$http_referer" '                       '"$http_user_agent" "$http_x_forwarded_for"';     access_log  logs/access.log  main;     sendfile        on;     tcp_nopush      on;     tcp_nodelay    on;     server_tokens off;      keepalive_timeout  60;     server_names_hash_bucket_size 128;     client_header_buffer_size 32k;     large_client_header_buffers 1 128k;# 4 32k     client_max_body_size 8m;     client_body_buffer_size 128k;     fastcgi_connect_timeout 60;     fastcgi_send_timeout 60;     fastcgi_read_timeout 60;     fastcgi_buffer_size 256k;     fastcgi_buffers 4 512k;#8 128     fastcgi_busy_buffers_size 512k;     fastcgi_temp_file_write_size 512k;     #fastcgi_intercept_errors on;     gzip on;     gzip_min_length 1k;     gzip_buffers    1 64k; #4 16     gzip_http_version 1.0;     gzip_comp_level 2;     gzip_types      text/plain application/x-javascript text/css application/xml;     gzip_vary on;     include /data/app_platform/nginx/conf/conf.d/*.conf;     server {           listen      80        default;           server_name _;           return 403;             } }

Nginx主配置文件关键部分就是这里，表明passenger是整合到Nginx中的。     passenger_root /data/app_platform/passenger;     passenger_ruby /usr/bin/ruby;     passenger_max_pool_size 10;     passenger_debug_log_file /data/app_data/nginx/logs/passenger.log;     passenger_show_version_in_header on;     passenger_spawn_method smart;

添加虚拟主机

server {     server_name xxx.com.cn;      access_log  /data/app_data/nginx/logs/xxx.log main;     root /data/zmkm_app/zmkm/public/;     passenger_enabled on;     index index.html index.htm;     location /assets/LiveVideo.swf {         root /data/zmkm_app/zmkm/public/;         index index.html index.htm;         passenger_enabled on;     } }

需要注意的如果虚拟主机制定的目录下需要Nginx处理ruby代码则需要加上passenger_enabled on;这条这令，并且location指定的内容还需要再次添加
