Experiment: Deploy and implement the static and dynamic separation and load balancing of Nginx on HTTP

First review the LB cluster load Balancer cluster

Four layers:

Lvs

Nginx (Stream)

Haproxy (MODE_TCP)

Seven floor

Http protocol

Nginx (Http,upstream)

Haproxy (Mode HTTP)

Httpd/ats/perlbal/pound/...

Next, how to implement nginx load balancing in HTTP

The Ngx_stream_proxy_module module can dispatch the HTTP service, where the stream module has

Specialized server subcommands, unlike other servers, which are used to define virtual hosts

While the server in the stream module is used to define one server in the group, the server can be reused multiple times,

Define multiple servers, so server load balancing can be achieved.

#################################################################

1, the experimental environment preparation, at least three host, one of which as Nginx Dispatch server, equipped with two network cards

Configure NGINX,HTTPD and httpd on three hosts, and test for successful access to the page

[Email protected] nginx]# Curl http://172.18.10.10:80/test1.html

Test Page 1 on UpStream Server 1 (172.18.10.10)

[Email protected] nginx]# Curl http://172.18.10.11:80/test1.html

Test Page 1 on UpStream Server 2 (172.18.10.11)

Make 172.18.10.10 and 172.18.10.11 a dynamic site (install httpd+php, i.e. Ap,listen 80)

172.18.10.10 and 172.18.10.11 as static sites (where 10.11 installs Nginx, monitor 8080,10.10 Configure virtual host, monitor 80 and 8080)

2, the purpose of the experiment. Implementation of Nginx load balancing for static content and dynamic content

3. Start configuration operation

Edit the PHP page under 172.18.10.10

[Email protected] ~]# vim/var/www/html/index.php

<H1>HTTPD Listend on server1

<?php

Phpinfo ();

?>

Send the experiment page to the 172.18.10.11 page file storage path

[Email protected] ~]# scp/var/www/html/index.php 172.18.10.11:/var/www/html/

Modify Server1 to Server2

<H1>HTTPD Listend on server2

<?php

Phpinfo ();

?>

4, common sense use Google browser request two address, to see if the test page can display properly--------tested found to be able to display the normal

5, configure the static site Nginx

SCP of the prepared Nginx packages to two hosts respectively

[Email protected] ~]# SCP nginx-1.6.2-1.el6.ngx.x86_64.rpm 172.18.10.10:/root/

6. Installing Nginx

[email protected] ~]# Yum install nginx-1.6.2-1.el6.ngx.x86_64.rpm

7. Configure virtual services for static sites

On 172.18.10.10:

Note DocumentRoot Path

#DocumentRoot "/var/www/html"

Add a new Listening port

#Listen 12.34.56.78:80

Listen 80

Listen 8080

Add a virtual host, listening on ports 80 and 8080, respectively

<virtualhost *:80>

Documentroot/var/www/shope

ServerName www.magedu.com

</VirtualHost>

<virtualhost *:8080>

Documentroot/var/www/html

ServerName imgs.magedu.com

</VirtualHost>

Save exit

Create a Directory

[Email protected] ~]# Mkdir/var/www/shope

Move index.php to this directory

[Email protected] ~]# mv/var/www/html/index.php/var/www/shope/

Check syntax

[Email protected] ~]# httpd-t

Restart HTTPD Service

[Email protected] ~]# service httpd restart

stopping httpd: [OK]

Starting httpd:httpd:Could not reliably determine the server ' s fully qualified domain name, using Localhost.localdomain For ServerName

[OK]

Access test 80 and port 8080 separately on the browser side

Results are normal.

On 172.18.10.11:

[Email protected] ~]# vim/etc/nginx/conf.d/default.conf

Change the virtual host listening port to 8080

Listen ———————------"Listen 8080;

Change the root path

root/usr/share/nginx/html, ————— "root/data/html;

Create a virtual Host directory path

[Email protected] ~]# MKDIR/DATA/HTML-PV

mkdir:created directory '/data '

mkdir:created directory '/data/html '

Move all test files to the/data/html directory

[Email protected] ~]# mv/var/www/html/test*/data/html/

Start the Nginx service and see if the port listens

[Email protected] ~]# Nginx

[Email protected] ~]# SS-TNL

State recv-q Send-q Local Address:port Peer Address:port

LISTEN 0 128 *:8080 *:*

LISTEN 0 128::: 80 :::*

LISTEN 0 128::: 22 :::*

LISTEN 0 128 *:22 *:*

LISTEN 0 100:: 1:25 :::*

LISTEN 0 100 127.0.0.1:25

Visit the page. See if you can access it properly

8. Nginx Service on the 172.18.200.100 of the Nginx Dispatch end

[Email protected] ~]# vim/etc/nginx/nginx.conf

#使用默认的加权轮询算法, the binding will be made

Upstream Websrvs {

Server 172.18.10.10:80 weight=2 max_fails=2 fail_timeout=2;

Server 172.18.10.11:80 weight=3;

}

Upstream Staticsrvs {

Server 172.18.10.10:8080 weight=1;

Server 172.18.10.11:8080 weight=1;

}

9, edit the scheduling method

[Email protected] ~]# vim/etc/nginx/conf.d/default.conf

Index index.php index.html; # # # #全局定义, sequencing

Location/{

Proxy_pass Http://websrvs; # # #动态资源加载路径定义

root/usr/share/nginx/html;

Index index.php index.html index.htm;

}

Location ~* \. (jpg|jpeg|png|gif|html) $ {

Proxy_pass Http://staticsrvs; # # # #静态资源加载路径定义

Index index.php;

}

10. New Load Test

[Email protected] ~]# nginx-t

Nginx:the configuration file/etc/nginx/nginx.conf syntax is OK

Nginx:configuration file/etc/nginx/nginx.conf Test is successful

[Email protected] ~]# Nginx-s Reload

Open Google Browser, enter the Http://172.18.200.100/Refresh page found will have the following page content to switch back and forth

HTTPD Listend on Server2

HTTPD Listend on Server1

Request http://172.18.200.100/index.php, found also the following page content switch back and forth

HTTPD Listend on Server2

HTTPD Listend on Server1

Use curl from other clients to test

[[email protected] ~]# for ((i=1;i<=10;i++));d o Curl http://172.18.200.100/index.php; Done

Test results: Load balancing for dynamic content

Next request static file: Http://172.18.200.100/test1.html, constantly refreshed, found to have the following to switch back and forth

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Use curl from other clients to test

[[email protected] ~]# for ((i=1;i<=10;i++));d o Curl http://172.18.200.100/test1.html; Done

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Test Page 1 on UpStream Server 1 (172.18.10.10)

Test Page 1 on UpStream Server 2 (172.18.10.11)

Test result: To achieve dynamic content of the responsible balance

The result is static and dynamic separation, and we can define the cache to improve the efficiency.
