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. [ "$NETWORKING" = "no" ] && exit 0 nginx="/data/app_platform/nginx/sbin/nginx" prog=$(basename $nginx) sysconfig="/etc/sysconfig/$prog" lockfile="/var/lock/subsys/nginx" pidfile="/data/app_data/nginx/logs/nginx.pid" NGINX_CONF_FILE="/data/app_platform/nginx/conf/nginx.conf" [ -f $sysconfig ] && . $sysconfig start() { [ -x $nginx ] || exit 5 [ -f $NGINX_CONF_FILE ] || exit 6 echo -n $"Starting $prog: " daemon $nginx -c $NGINX_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc -p $pidfile $prog retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { configtest_q || return 6 stop start } reload() { configtest_q || return 6 echo -n $"Reloading $prog: " killproc -p $pidfile $prog -HUP echo } configtest() { $nginx -t -c $NGINX_CONF_FILE } configtest_q() { $nginx -t -q -c $NGINX_CONF_FILE } rh_status() { status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } # Upgrade the binary with no downtime. upgrade() { local oldbin_pidfile="${pidfile}.oldbin" configtest_q || return 6 echo -n $"Upgrading $prog: " killproc -p $pidfile $prog -USR2 retval=$? sleep 1 if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]]; then killproc -p $oldbin_pidfile $prog -QUIT success $"$prog online upgrade" echo return 0 else failure $"$prog online upgrade" echo return 1 fi } # Tell nginx to reopen logs reopen_logs() { configtest_q || return 6 echo -n $"Reopening $prog logs: " killproc -p $pidfile $prog -USR1 retval=$? echo return $retval } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart|configtest|reopen_logs) $1 ;; force-reload|upgrade) rh_status_q || exit 7 upgrade ;; reload) rh_status_q || exit 7 $1 ;; status|status_q) rh_$1 ;; condrestart|try-restart) rh_status_q || exit 7 restart ;; *) echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs}" exit 2 esac
Nginx主配置文件/data/app_platform/nginx/conf/nginx.conf user www; worker_processes 4; error_log /data/app_data/nginx/logs/error.log error; pid /data/app_data/nginx/logs/nginx.pid; worker_rlimit_nofile 65535; events { use epoll; worker_connections 10240; } http { passenger_root /data/app_platform/passenger; passenger_ruby /usr/bin/ruby; passenger_max_pool_size 10; passenger_debug_log_file /data/app_data/nginx/logs/passenger.log; passenger_show_version_in_header on; passenger_spawn_method smart; include mime.types; default_type application/octet-stream; log_format main '$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
