nodejs与nginx的完美搭配

引言

node自己本身可以作为服务器进行驱动，但是node本身对文件的处理能力并不是很好，所以当我们的生产环境中应尽量使用nginx来处理静态的资源以及反向代理，同时也解决了node分布式以及负载均衡的相关问题。

nginx的安装以及配置

这里以cenos环境为基础进行配置

1、基础编译环境的配置C/C++等编译工具以及工具库：

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

2、PRCE安装
（1）下载：

wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

（2）解压

tar -zxvf pcre-8.35.tar.gz

（3）安装

cd pcre-8.35
./configure
make && make install

3、安装Nginx
（1）下载

 wget http://nginx.org/download/nginx-1.10.3.tar.gz

（2）解压、安装

tar -zxvf nginx-1.10.3.tar.gz
cd /nginx-1.10.3
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
make && make install

（3）是否安装成功

/usr/local/webserver/nginx/sbin/nginx -v

能够查看版本号说明安装成功

（4）配置

/usr/sbin/groupadd www 
/usr/sbin/useradd -g www www

（5）实现node反向代理

    node默认端口号为3000

编辑 nginx.conf 文件

    #user  nobody;
worker_processes  1; ##默认的CPU核心数

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

#pid        logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

events {
    #进行如下配置
    use epoll;
    worker_connections  65535;
}


http {
    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;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;
#主机配置
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;
    #修改反向代理地址
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host  $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_set_header Connection "";
       proxy_pass http://127.0.0.1:3000;
       proxy_redirect default;
       # 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;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}


# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#    listen       8000;
#    listen       somename:8080;
#    server_name  somename  alias  another.alias;

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


# HTTPS server
#
#server {
#    listen       443 ssl;
#    server_name  localhost;

#    ssl_certificate      cert.pem;
#    ssl_certificate_key  cert.key;

#    ssl_session_cache    shared:SSL:1m;
#    ssl_session_timeout  5m;

#    ssl_ciphers  HIGH:!aNULL:!MD5;
#    ssl_prefer_server_ciphers  on;

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

}

查看是否配置成功：

/usr/local/webserver/nginx/sbin/nginx -t

打印如下信息代表成功：

nginx: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/webserver/nginx/conf/nginx.conf test is successful

（6）启动

/usr/local/webserver/nginx/sbin/nginx

3、实现负载均衡：
