主配置文件:nginx.conf

user www;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

    worker_connections  102400;
}


http {
    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  /var/log/nginx/access.log  main;

    sendfile            on;

    include             /etc/nginx/mime.types;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;
}

目录下 /etc/nginx/conf.d/one.conf

#
# The default server
#

upstream one_server{
    server 127.0.0.1:8090 weight=1;
    #server 127.0.0.1:8091 weight=1;            
}


server {
    listen       80;
    server_name  one.server.com;

    #charset koi8-r;

    access_log  /data/logs/one.access.log  main;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
        
        index  index.htm index.html;

        proxy_pass   http://one_server;    #在这里设置一个代理,和upstream的名字一样
        #以下是一些反向代理的配置可删除
        proxy_redirect             off; 
        #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
        proxy_set_header           Host $host; 
        proxy_set_header           X-Real-IP $remote_addr; 
        proxy_set_header           X-Forwarded-For $proxy_add_x_forwarded_for; 
        client_max_body_size       10m; #允许客户端请求的最大单文件字节数

        proxy_connect_timeout      300; #nginx跟后端服务器连接超时时间(代理连接超时)
        proxy_send_timeout         300; #后端服务器数据回传时间(代理发送超时)
        proxy_read_timeout         300; #连接成功后,后端服务器响应时间(代理接收超时)
        proxy_buffer_size          4k; #设置代理服务器(nginx)保存用户头信息的缓冲区大小
        proxy_buffers              4 32k; #proxy_buffers缓冲区,网页平均在32k以下的话,这样设置
        proxy_busy_buffers_size    64k; #高负荷下缓冲大小(proxy_buffers*2)
        proxy_temp_file_write_size 64k;
        

    }

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/html;
    }

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

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

可以增加多个 one.conf 文件配置多个系统的负载均衡,反向代理

 

单独的图片服务器:img111.conf

#
# The default server
#
server {
    listen       80;
    server_name  img111.server.com;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
        root   /data/www/webapp/;
        index  index.html index.htm;
    }

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/html;
    }

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

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