Nignx配置

  1、先要安装nignx得先安装pcre库

tar zxvf pcre-7.7.tar.gz
　　cd pcre-7.7/
　　./configure
　　make && make install
　　cd ../

　　2、安装Nginx
　　tar zxvf nginx-0.7.14.tar.gz
　　cd nginx-0.7.14/
　　./configure --prefix=/usr/local/nginx --with-http_stub_status_module　make && make install
　　cd ../

   3、修改Nginx配置文件

    vi conf/nginx.conf

#运行用户
user  nobody nobody;

#启动进程
worker_processes  1;

#全局错误日志及PID文件
error_log  logs/error.log notice;
pid        logs/nginx.pid;

#工作模式及连接数上限
events {
        use epoll;
        worker_connections      1024;
}

#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
        #设定mime类型
        include       conf/mime.types;
        default_type  application/octet-stream;

        #设定日志格式
        log_format main         '$remote_addr - $remote_user [$time_local] '

                                                '"$http_referer" "$http_user_agent" '
                                                '"$gzip_ratio"';

        log_format download '$remote_addr - $remote_user [$time_local] '
                                                '"$request" $status $bytes_sent '
                                                '"$http_referer" "$http_user_agent" '
                                                '"$http_range" "$sent_http_content_range"';

        #设定请求缓冲
        client_header_buffer_size    1k;
        large_client_header_buffers  4 4k;

        #开启gzip模块
        gzip on;

        #设定access log

        client_body_timeout    3m;
        send_timeout           3m;

        sendfile                on;
        tcp_nopush              on;
        tcp_nodelay             on;

        keepalive_timeout  65;

        #设定负载均衡的服务器列表
        upstream mysvr {
                #weigth参数表示权值，权值越高被分配到的几率越大
                #本机上的Squid开启3128端口
                server 192.168.192.200:8080  weight=1;

                charset gb2312;

                #设定本虚拟主机的访问日志
                access_log  logs/www.o.cn.access.log  main;

                #如果访问 /img/*, /js/*, /css/* 资源，则直接取本地文件，不通过squid
                #如果这些文件较多，不推荐这种方式，因为通过squid的缓存效果更好
                location ~ ^/(img|js|css)/  {
                        root    /data/comm/web_www/;
                        expires 24h;
                }

                #对 "/" 启用负载均衡
                location / {
                        proxy_pass     http://mysvr;

                        proxy_redirect          off;
                        proxy_set_header        Host $host;

                        proxy_busy_buffers_size 64k;
                        proxy_temp_file_write_size 64k;
                }

                #设定查看Nginx状态的地址
                location /NginxStatus {
                        stub_status             on;
                        access_log              on;
                        auth_basic              "NginxStatus";
