nginx 配置tomcat 实现负载均衡

环境：

准备三台机械： 两台安装tomcat 一台安装nginx;

安装步骤省略；

tomcat一台的IP：http://192.168.195.132:8080

另一台tomcat一台的IP：http://192.168.195.133:8080

nginxIP:http://192.168.195.134

主要：

nginx的配置文件nginx.conf：

#user  nobody;

worker_processes  1;

#error_log  logs/error.log;

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {

    worker_connections  1024;

}

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;

    upstream myServer{  

      server 192.168.195.132:8080 weight=1;  #weight权重 权重越大访问的概率越大

      server 192.168.195.133:8080 weight=2;  

    } 

    #gzip  on;

    server {

        listen       8080;

        server_name  192.168.195.134;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

       location / {  

            proxy_pass http://myServer;  #注意 http://后面的名字需要与  upstream myServe 的一致

            proxy_redirect default;  

        }  

        #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

        #    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

    #    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;

分别启动两台tomat 访问路径如：

http://192.168.195.132:8080/examples/index.html

另外一台：

http://192.168.195.133:8080/examples/index.html
