Windows+nginx+tomcat Build load balancing and cluster environment simultaneously realize session sharing (I.)

absrtact : With the visit of the website more and more, so consider to add server to the website, now more popular practice is to do the cluster environment for the site, the following I do the process of recording, to facilitate future viewing, but also hope to help to have the need of friends.

One: First, the environment:

1.JDK 1.6.0_45

2.tomcat 6.0.44

3.nginx 1.8.0

Second: The installation of Jdk,tomcat,nginx:

1.JDK installation Please refer to: Click to open the link

Installation steps for 2.nginx

(1). First download the Nginx version of Windows, I download the Nginx 1.8.0 version, download the address: Click to open the link

(2). After the download is complete, extract directly to a path without Chinese, I am here to extract to: D:\server\nginx-1.8.0

(3). Through the DOS command into the nginx-1.8.0 directory to start the Nginx can be

(4) Operation Nginx Command under Windows

1. Start Nginx.exe start Nginx 2 nginx-s stop nginx-s quit

Stop stops Nginx immediately and does not save related information

Quit indicates a normal exit Nginx and holds information 3. Reboot nginx-s reload reboot (reboot required because of configuration change)

3.tomcat installation (directly to Tomcat's official website to download the uncompressed version of the Can)

Three: To download the download of Tomcat copied 3, altogether is a, of which three do Qdksdemo cluster environment, and the other three do Qdkydemo cluster environment, the specific screenshot as follows:

After the replication is complete, modify each tomcat's port and session share configuration separately, as follows:

1. The first port number to be modified

<server port= "8005" shutdown= "Shutdown" >

2. The second port number to be modified

<connector port= "8081" protocol= "http/1.1" connectiontimeout= "20000" 
               redirectport= "8443"/>

3. The third port number to be modified

<connector port= "8009" protocol= "ajp/1.3" redirectport= "8443"/>

4. Fourth to increase the session sharing configuration, this can see the official file of Tomcat, which has a configuration directly copied to the Server.xml can be, address: http://tomcat.apache.org/tomcat-6.0-doc/ Cluster-howto.html

<cluster classname= "Org.apache.catalina.ha.tcp.SimpleTcpCluster" channelsendoptions= "6" >
                   <manager classname= "Org.apache.catalina.ha.session.BackupManager" expiresessionsonshutdown= "false"

Such a tomcat configuration file is modified, and the other 5 tomcat configurations are the same as this one, except for the same port.

Four: Nginx configuration:

1. First, create a new folder in the Nginx directory to store the cluster profiles between the different projects, as shown in the following figure:

2. Create a new configuration file in the Manyvhost folder for the cluster configuration of two projects, as shown in the following figure:

The configuration of 3.qdks.conf and qdky.conf is as follows:

(1). qdks.conf

Upstream Qdks {server localhost:8081 weight=1;
	Server localhost:8082 weight=1;
Server localhost:8083 weight=1;
	} server {Listen 8086;

	server_name 192.168.1.103;
	Error_page 502 503 504/50x.html;
	Location =/50x.html {root html;

	} Root/data/projects/ycp/bill; #-Rewrite:if (Path ~ "^/assets/(. *)") goto "/public/assets/$1" # location ~ ^/static/assets/(. *) $ # {#alias
	/data/projects/payment/web/public/assets/$1;
	# Access_log off;
	# #expires 3d;
			#} location/{index index.html index.htm index.jsp;
	 } location ~. * {# Proxy_pass_header Server;
	Proxy_set_header Host $http _host;
	 # proxy_redirect off;
	 Proxy_set_header X-real-ip $remote _addr;
	 Proxy_set_header X-scheme $scheme;
	 Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
	 Add_header Pragma "No-cache";
	Proxy_pass Http://qdks;

	} rewrite ^/admin/?$/admin/login redirect; # for rewrite rewrite ^/(channel|admin|mobile|api|web)/(. *) $/public/index.php/$2 last;
	#redirect to Mobile WAP #rewrite ^$/m redirect;

#rewrite ^/$/mobile/user redirect; }

(2). qdky.conf

Upstream Qdky {server localhost:7081 weight=1;
   Server localhost:7082 weight=1;
Server localhost:7083 weight=1;
	} server {Listen 7086;
	server_name 192.168.1.103;
	Error_page 502 503 504/50x.html;
	Location =/50x.html {root html;

	} Root/data/projects/ycp/bill; #-Rewrite:if (Path ~ "^/assets/(. *)") goto "/public/assets/$1" # location ~ ^/static/assets/(. *) $ # {#alias
	/data/projects/payment/web/public/assets/$1;
	# Access_log off;
	# #expires 3d;
			#} location/{index index.html index.htm index.jsp;
	 } location ~. * {# Proxy_pass_header Server;
	Proxy_set_header Host $http _host;
	 # proxy_redirect off;
	 Proxy_set_header X-real-ip $remote _addr;
	 Proxy_set_header X-scheme $scheme;
	 Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
	 Add_header Pragma "No-cache";
	Proxy_pass Http://qdky;
	
	} rewrite ^/admin/?$/admin/login redirect; # for rewrite rewrite ^/(channel|admin|mobile|api|web)/(. *) $/public/index.php/$2 last;
	#redirect to Mobile WAP #rewrite ^$/m redirect;



#rewrite ^/$/mobile/user redirect; }

These two profiles are the configuration files in my current environment, where the port number of the Qdks project is 8086, and the following three Tomcat ports are: 8081,8082,8083;qdky 7086, and the following three tomcat port number is: 7081, 7082,7083

4. Finally, the cluster configuration of the above two projects is introduced into the nginx.conf core configuration file in the Nginx conf directory, as follows:

#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;

    #压缩级别从低到高1-9 gzip_types text/plain application/x-javascript text/css application/xml;

    Gzip_vary on;

}

V: Deploy the corresponding project separately to test whether the cluster environment we configured above is normal

1. Download the corresponding project source code, download and extract to your local workspace below, my path is: D:\workspace_qdexam\qdksDemo and D:\workspace_qdexam\qdkyDemo

Qdksdemo's download Address: http://download.csdn.net/detail/sxdtzhaoxinguo/9187453

Qdkydemo's download Address: http://download.csdn.net/detail/sxdtzhaoxinguo/9187455

2. Deploy to the corresponding tomcat below, here I am using the direct mapping path method

(1). The Qdksdemo deployment method is to create a new configuration file Qdksdemo.xml under the corresponding three Tomcat Conf\catalina\localhost directory, which reads as follows:

<context    path= "/qdksdemo"   docbase= "D:\workspace_qdexam\qdksDemo\WebContent"     debug= "0"    Privileged= "true" >      </Context>

(2). The Qdkydemo deployment method is to create a new profile qdkydemo.xml under the corresponding three Tomat Conf\catalina\localhost directory, which reads as follows:

<context path= "/qdkydemo"   docbase= "D:\workspace_qdexam\qdkyDemo\WebContent" debug= "0" privileged= "true" ></Context>

3. Start each of these 6 tomcat, as shown below:

4. Start Nginx, as shown below:

5. Finally, through the browser to access the two projects, the following figure:

Click Refresh Separately, you will find that the actual access to the above port will change, but the following session ID is unchanged, which means that based on Nginx and Tocmat cluster built successfully.

Finally I put my tomcat and nginx all packed and uploaded for your reference.
