nginx+tomcat load balancing

1. Environment introduction

1. There are 3 virtual machines in this experiment (rhel6.2-64)

192.168.232.147 (nginx) 192.168.232. 154 (tomcat)

192.168.232.155 (tomcat)

2. Install and configure JDK

3. Configure related environment variables (profile, hosts)

4. Prepare a web project to test whether it is loaded Balanced, this experiment uses a previously written permission management module

2. Install and configure tomcat

1. Install tomcat on 192.168.232.154, 192.168.232.155 machines

2. Download a linux version of apache-tomcat-7.0.64.tar.gz and unzip it to use

3. Add

<Context  path="" docBase="/root/webapps/permission" reloadable="false"/>

in the tag 4. Create the /root/webapps directory, and then put the permission Place this web project in this directory, start tomcat, visit

http://192.168.232.154:8080/, http://192.168.232.154:8080/ to access the homepage of the permission project

3. Install and configure Nginx

1. Download nginx-1.2.6.tar.gz and unzip it to the specified directory

2. Ensure the running environment for nginx compilation

3. Install pcre-devel openssl openssl-devel

(1) Configure local yum so that yum can find the installation package when installing

(2) Installation: yum -y install pcre-devel openssl openssl-devel

4. Create www user: useradd www

5. Prepare the compilation and installation environment

./configure --user=www --group=www --prefix=/usr/local/nginx - -with-http_stub_status_module --with-http_ssl_module

6. Compile and install, go to the root directory of nginx decompression: cd /root/app/nginx-1.2.6

make && make install

7. Check whether nginx installation is successful

[root@storm1 nginx-1.2.6]# /usr/local/nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/ nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

8. Visit nginx default homepage: http://192.168.232.147:80/, OK See the nginx welcome main page

Now Nginx is installed

Fourth, configure nginx+tomcat integration. In fact, you only need to configure nginx, and tomcat does not need to be touched

1. Go to the directory specified for installation: / usr/local/nginx, simply change nginx.conf to the following

user  www www;
worker_processes  1;
pid     /usr/local/nginx/logs/nginx.pid;
events {
    use epoll;
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    include     /usr/local/nginx/conf/proxy.conf;
    sendfile        on;
    tcp_nopush      on;
    keepalive_timeout  65;
    log_format  $upstream_addr  $status $request_time   $time_local     $remote_user    $http_user_agent;
    upstream panguoyuan.com {
      server  192.168.232.154:8080;
      server  192.168.232.155:8080;
                }

        server{
            listen 80;
            server_name panguoyuan.com;
            location / {
                proxy_pass         http://panguoyuan.com;
                proxy_set_header   Host             $host;
                proxy_set_header   X-Real-IP        $remote_addr;
                proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
            }
        }
}

2. The hosts on the 192.168.232.147 machine are as follows

[root@storm1 conf]# cat /etc/hosts 192.168.232.147 storm1

192.168.232.154 Storm2

192.168.232.155 Storm3192.168.232.147 PAANOYUAN.com
