一个简单的负载均衡的示例

void — Fri, 26 Jun 2009 02:35:00 GMT

== 一个简单的负载均衡的示例，把www.domain.com均衡到本机不同的端口，也可以改为均衡到不同的地址上。 ==



http {

: upstream myproject {

: server 127.0.0.1:8000 weight=3;

: server 127.0.0.1:8001;

: server 127.0.0.1:8002;

: server 127.0.0.1:8003;

: }
: server {

: listen 80;

: server_name www.domain.com;

: location / {

: proxy_pass http://myproject;

: }

: }

}

用nginx+tomcat来代替apache+jk+tomcat

void — Wed, 06 Aug 2008 06:59:00 GMT

vi /usr/local/nginx/conf/nginx.conf

给出一些主要更改的地方
user  nobody nobody;
worker_processes  2;
error_log  logs/error.log  notice;
pid        logs/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    include    /usr/local/nginx/conf/proxy.conf;
#上面这行是增加的
    server {
        listen       81;
        server_name  localhost;
        charset gb2312;
# serve static files
        location ~ ^/(images|pages|javascript|js|css|flash|media|static)/  {
                root    /usr/local/www;
                expires 30d;
        location / {
            root /usr/local/www;
            index  index.jsp index.htm;
            proxy_pass http://192.168.1.250:8080;
          }

location /NginxStatus {
                        stub_status             on;
                        access_log              on;
                        auth_basic              "NginxStatus";
                }

说明配置文件中有提到proxy.conf 这个文件可以VI一个如下文件
[root@test conf]# cat proxy.conf
#!nginx (-)
# proxy.conf
proxy_redirect          off;
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;
client_body_buffer_size 128k;
proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffers           32 4k;
测试配置文件
[root@test conf]# /usr/local/nginx/sbin/nginx -t
2008/05/04 15:40:02 [info] 2363#0: the configuration file /usr/local/nginx/conf/nginx.conf syntax is

ok
2008/05/04 15:40:02 [info] 2363#0: the configuration file /usr/local/nginx/conf/nginx.conf was tested

successfully
启动
[root@test conf]# /usr/local/nginx/sbin/nginx
[root@test conf]# ps fax

9402 ?        S      0:00  \_ nginx: worker process

http://192.168.1.250:81/NginxStatus
Active connections: 1
server accepts handled requests

http://192.168.1.250:81就可以访问我的页面了用着个nignx+tomcat来替代apache+jk+tomcat
同样的可以让squid来监听80端口这样就透明代理了
查看服务器信息
[root@test conf]# curl -I http://localhost

Nginx + SSL 配置

void — Wed, 06 Aug 2008 04:14:00 GMT

安装nginx之前先安装 openssl 和 openssl-devel
编译nginx时使用 --with-http_ssl_module 就可以支持SSL了

然后需要生成服务器证书，没钱就用openssl自己作一个

openssl req -new -x509 -nodes -out eglic.crt -keyout eglic.key

增加一个虚拟主机

server { listen 443; ssl on; ssl_certificate /opt/eglic.crt; ssl_certificate_key /opt/eglic.key; server_name www.eglic.com; charset gb2312; index index.php index.html index.htm; root /var/www/eglic; location / { index index.php index.html index.htm; rewrite ^/show-([0-9]+)-([0-9]+)\.html$ /index.php?action=show&id=$1&page=$2 last; rewrite ^/category-([0-9]+)-([0-9]+)\.html$ /index.php?action=index&cid=$1&page=$2 last; rewrite ^/archives-([0-9]+)-([0-9]+)\.html$ /index.php?action=index&setdate=$1&page=$2 last; rewrite ^/(archives|search|reg|login|index|links)\.html$ /index.php?action=$1 last; rewrite ^/(comments|tagslist|trackbacks|index)-([0-9]+)\.html$ /index.php?action=$1&page=$2 last; } location ~ .*\.php?$ { fastcgi_pass 127.0.0.1:10086; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE eglic/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; } }

现在可以通过 https://www.eglic.com/访问我了！

Nginx 简单的负载均衡配置示例

void — Fri, 01 Aug 2008 01:47:00 GMT

www.s135.com 和 blog.s135.com 域名均指向 Nginx 所在的服务器IP。

　　用户访问http://www.s135.com，将其负载均衡到192.168.1.2:80、192.168.1.3:80、192.168.1.4:80、192.168.1.5:80四台服务器。

　　用户访问http://blog.s135.com，将其负载均衡到192.168.1.7服务器的8080、8081、8082端口。

　　以下为配置文件nginx.conf：

user www www;

worker_processes 10;

#error_log logs/error.log;
