Nginx + tomcat load balancing

: This article mainly introduces nginx + tomcat server load balancer. if you are interested in the PHP Tutorial, refer to it. I. environment introduction

1. a total of three virtual machines (rhel6.2-64) in this experiment)

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 server load balancer works. this experiment uses a previously written permission management module.

II. install and configure tomcat

1. install tomcat on machines 192.168.232.154 and 192.168.232.155

2.download a Linux-based apache-tomcat-7.0.64.tar.gz file to decompress it.

3. in Label

4. create the/root/webapps directory and put the permission web project under this directory, start tomcat, and access

Http: // 192.168.232.154: 8080/, http: // 192.168.232.154: 8080/You can access the homepage of the permission project

3. install and configure Nginx

1. download nginx-1.2.6.tar.gz and decompress it to the specified directory.

2. ensure that the nginx compiling environment is ready for running.

3. install pcre-devel openssl-devel

(1) configure the local yum so that the yum installation package can be found

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

4. create a www user: useradd www

5. prepare the compiling 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, enter the nginx decompressed root directory: 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-t
Nginx: 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 the nginx default homepage: http: // 192.168.232.147: 80/. you can see the nginx welcome homepage.

Nginx installation is complete.

4. Configure nginx + tomcat integration. you only need to configure nginx and tomcat.

1. go to the directory specified for installation:/usr/local/nginx, and 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 192.168.232.147 is as follows:

[Root @ storm1 conf] # cat/etc/hosts
192.168.232.147 storm1
192.168.232.154 storm2
192.168.232.155 storm3
192.168.232.147 panguoyuan.com
