Configure apache2.2.10 Load Balancing + mod_jk-1.2.28 + atat6 cluster (Linux)

1. install Apache

 

Apache2.2.11 installation and configuration

1. Decompress Apache and read the install file in the httpd directory.

# Tar-zxvf httpd-2.2.11.tar.gz

You can move the obtained folder to the installation directory/usr/local.

# Cd httpd-2.2.11

#./Configure

#./Configure -- prefix =/usr/local/apache2 -- enable-mod-shared = all

# Make

# Make install

# Cd/usr/local/apache2/bin

#./Apachectl start

 

Enter http: // localhost/in the address bar. If the it works welcome page is displayed, the request is successful.

Reference: http://httpd.apache.org/docs/2.2/install.html

 

2 configure Apache/CONF/HTTP. conf

 

My projects are stored in/usr/local/apache2/htdocs (the default directory of Apache)

Add :( make Apache not access the WEB-INF directory)

 

<Directory "/usr/local/apache2/htdocs/WEB-INF">

Order allow, deny

</Directory>

 

Enable the annotation configuration language to set the default Chinese character.

Include CONF/extra/httpd-languages.conf

 

Add: Japanese is supported.

Defaultlanguage ja-JP

Adddefacharcharset UTF-8

 

 

2. Install jk_mod and integrate Apache and tomcat.

1. Copy the downloaded binary mod_jk-1.2.28-httpd-2.2.x.so to the modules directory of Apache.

: Http://apache.mirror.phpchina.com/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.28/

 

2. Create two new files, mod_jk.conf and workers. properties, in the conf directory of Apache,

The content of mod_jk.conf is the JK configuration file, including the loading module and log information, as well as the designated parser and directory. Workers. properties is the Tomcat wokers configuration file.

 

3. Add the following content to mod_jk.conf (the mod_jk.conf file is convenient for management, and you do not need to write the configuration in httpd. conf)

 

# Load JK module. The name must correspond

Loadmodule jk_module modules/mod_jk-1.2.28-httpd-2.2.x.so

# Load the newly created workers. properties File

Jkworkersfile CONF/workers. Properties

 

# Jk log file

Jklogfile logs/mod_jk.log

 

# Jk log level. The parameters include [debug/error/info]

Jkshmfile logs/mod_jk.shm

Jkloglevel info

 

# Jk log data format

Jklogstampformat "[% A % B % d % H: % m: % S % Y]"

 

# Some configuration options of JK: Indicate to send SSL key size,

Jkoptions + forwardkeysize + forwarduricompat-forwarddirectories

# JK request log format

Jkrequestlogformat "% w % v % t"

 

# Submit the JSP do Servlet File to Tomcat for processing

Jkmount/servlet/* ajp13

Jkmount/*. jsp ajp13

Jkmount/*. Do ajp13

# Jkmount indicates that Tomcat is used for parsing, while jkunmount indicates that the opposite is true.

 

# Generally, JSP and Servlet programs can be processed by Tomcat, and static file images are still processed by Apache.

 

# Jkautoalias/usr/local/apache2/htdocs *

# All static files in this folder are automatically processed by Apache.

 

Jkmount/servlet/* ajp13

#/Test/servlet/all files are also handed over to Tomcat for processing

 

4. Edit the httpd. conf file of Apache and load the jk_mod.conf file in:

Include CONF/mod_jk.conf

 

5. Edit the workers. properties file and add the following content:

Workers. tomcat_home =/usr/local/tomcat/

Workers. java_home =/usr/Java/JDK/

PS =/

Worker. List = ajp13

Worker. ajp13.port = 8009

Worker. ajp13.host = localhost

Worker. ajp13.type = ajp13

Worker. ajp13.lbfactor = 1

# Configuration reference see http://tomcat.apache.org/connectors-doc/reference/workers.html

 

 

7. Restart Apache for testing

#./Apachectl restart

Open the browser and access the JSP file through the following two addresses respectively. If normal resolution is available, the integration is successful. According to the configuration of Apache and tomcat, test points to the same directory.

Http: // localhost/

Http: // localhost: 8080/

 

In this way, Apache and tomcat are sorted out with jk_mod.

 

3. Configure workers. Properties

 

Worker. list = controller, myworker1, myworker2, myworker3 <br/> worker. myworker1.port = 8009 <br/> worker. myworker1.host = 192.168.0.10 <br/> worker. myworker1.type = ajp13 <br/> worker. myworker1.lbfactor = 1 <br/> worker. list = myworker2 <br/> worker. myworker2.port = 8010 <br/> worker. myworker2.host = 192.168.0.10 <br/> worker. myworker2.type = ajp13 <br/> worker. myworker2.lbfactor = 1 <br/> worker. list = myworker3 <br/> worker. myworker3.port = 8011 <br/> worker. myworker3.host = 192.168.0.10 <br/> worker. myworker3.type = ajp13 <br/> worker. myworker3.lbfactor = 1 <br/> worker. controller. type = LB <br/> worker. controller. balanced_workers = myworker1, myworker2, myworker3 <br/> worker. controller. sticky_session = 1 

 

4. Configure mod_jk

Loadmodule jk_module modules/mod_jk-1.2.28-httpd-2.2.X.so <br/> jkworkersfile CONF/workers. properties <br/> jklogfile logs/mod_jk.log <br/> jkshmfile logs/mod_jk.shm <br/> jklogstampformat "[% A % B % d % H: % m: % S % Y] "<br/> jkrequestlogformat" % w % v % t "<br/> # jkmount /*. JSP myworker1 <br/> # jkmount /*. do myworker1 <br/> # jkautoalias/usr/local/apache2/htdocs * <br/> # jkmount/servlet/* myworker1 <br/> jkmount/* Controller 

 

5. Install Multiple Tomcat servers. The server. xml configuration is as follows:

6. Notes

 

(1) In tomcat

 

<Engine name = "standalone" defaulthost = "localhost" jvmroute = "controller">

 

Yes standalone jvmroute is the Server Load balancer Controller

 

(2)

 

<Distributable/> or set at your must be added in the web. xml file of the project.<Context distributable="true" />

 

(3)

 

 

<Cycler classname = "org. Apache. Catalina. tribes. Transport. NiO. nioreceiver"

Address = "Auto"

Port = "4006"

Selectortimeout = "100"

Maxthreads = "6"/>

 

 

The port range is 4000-4100.

 

(4) ensure that sticky session mode is configured in the balance manager.

 

Worker. Controller. sticky_session = 1

 

(5) The worker. ajp13.port = port 8009 must correspond to the <connector Port = "8009" protocol = "AJP/1.3" redirectport = "8443"/>

 

(6) worker. myworker3.lbfactor = 1 is the probability coefficient of balanced allocation. A larger value indicates a larger number of occurrences.
