tengine实现tomcat负载均衡

一、环境准备

服务器:

192.168.1.101   tomcat7、tengine

192.168.1.102   tomcat7

 

1、下载tengine-2.1.0.tar.gz---->http://tengine.taobao.org/download_cn.html

2、解压到192.168.1.101/opt目录下

  #[root@node1 opt]# tar -zxvf tengine-2.1.0.tar.gz

3、进入刚才的解压目录下:

   #[root@node1 tengine-2.1.0]#

4、执行编译环境准备

./configure \

  --error-log-path=/var/log/nginx/error.log \

  --http-log-path=/var/log/nginx/access.log \

  --pid-path=/var/run/nginx/nginx.pid  \

  --lock-path=/var/lock/nginx.lock \

  --with-http_ssl_module \

  --with-http_flv_module \

  --with-http_stub_status_module \

  --with-http_gzip_static_module \

  --http-client-body-temp-path=/var/tmp/nginx/client/ \

  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \

  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \

  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \

  --http-scgi-temp-path=/var/tmp/nginx/scgi \

  --with-pcre

 

./configure: error: the HTTP rewrite module requires the PCRE library.

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre=<path> option.

解决:

需要安装依赖包: 

 #yum  -y install  gcc*

   #yum  -y install  pcre*

#yum -y install pcre-devel

   #yum  -y install  zlib*

   #yum  -y install  openssl*

 

 注意:--prefix=/opt/new_soft\是指定安装路径,默认安装在/usr/local/nginx目录

 

二、检查正常后开始:编译、安装

#make

#make install

1、创建文件夹:mkdir  -p  /var/tmp/nginx/client/

2、启动

[root@node1 nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

3、浏览器访问:http://192.168.1.101/

 


 

三、配置tomcat访问负载均衡

1、进入/usr/local/nginx/conf目录下,修改配置文件

#vi nginx.conf

 

#user  nobody;

worker_processes  4; #进程数量:和cpu核数绑定

events {

    worker_connections  2048; #连接worker数

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    upstreamnginx{

       session_sticky cookie=uid fallback=on path=/  mode=insert option=indirect;

       server 192.168.1.101:8080   weight=2;

       server 192.168.1.102:8080   weight=1;

       check interval=3000 rise=2 fall=5 timeout=1000 type=http;

       check_http_send "HEAD /index.jsp HTTP/1.0\r\n\r\n";

       check_http_expect_alive http_2xx http_3xx;

    }

    server {

        listen       80;

server_name  10.37.49.185;#访问nginx的ip

        location / {

            session_sticky_hide_cookie upstream=nginx;

            proxy_passhttp://nginx;

            proxy_set_header  Host  $host;

            proxy_set_header X-Real-IP $remote_addr;

            root   html;

            index  index.html index.htm;

        }

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css)$ #实现静态资源访问
    { 
      root /data/tomcat/webapps/; #静态资源路径
      if (-f $request_filename) { 
        expires 1d; 
        break; 
      } 
     }  

       location /status {

         check_status ;#多个tomcat的健康检查

        }

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

            root   html;

        }

    }

}

 

2、启动tengine:[root@node1
nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

3、启动2台机器的tomcat:[root@node1
bin]# sudo sh startup.sh

4、浏览器访问:http://192.168.1.101/

可以实现访问tomcat

浏览器访问:http://192.168.1.101/status

可以监控tomcat状态
