The protocol mainly transmits data in binary format rather than text format. The use of TCP and packet-based protocols increases the performance of WEB servers.

Mod_jk and mod_proxy are based on the AJP protocol. Mod_jk is an AJP connector that is often used to integrate web servers with tomcat, such as Apache or IIS.

Download address: http://tomcat.apache.org/download-connectors.cgi (1) for decompression

[root@localhost opt] # tar-zxvf tomcat-connectors-2.2.x-src.tar

(2) run the configuration command

[root@localhost opt] # tar-zxvf tomcat-connectors-2.2.x-src.tar

(3) then run the compile command

[root@localhost apache-2.0] # make

(4) installation

Root@localhost apache-2.0] # make install

(5) copy the module to the modules directory of apache [root@localhost apache-2.0] # cp mod_jk.so / opt/apache-2.2.19/modules/chmod 755 mod_jk.so (6) Edit the configuration file [root@localhost apache-2.0] # cd / opt/apache-2.2.19/confvi mod-jk.confLoadModule jk_module modules/mod_jk.soJkWorkersFile conf/workers.propertiesJkLogFile logs/mod_jk.logJkLogLevel infoJkMount / sample/* node1

Create a file named workers.properties in the same directory

[root@localhost conf] # vi workers.propertiesworker.list=node1worker.node1.port=8009worker.node1.host=10.130.240.51worker.node1.type=ajp13worker.node1.lbfactor=1

Details of the configuration file:

Node name: usually the name of the host

Tocmcat accepts AJP port: default is 8009

IP address of tomcat

Protocol used

The method of load balancing

(7) Edit the httpd.conf file and include the file we just created.

Include conf/mod_jk.conf

(8) restart apache server 3. Mod_proxy configuration

It's a little easier than configuring mod_jk,mod_proxy.

(1) Open the httpd.conf configuration file and add the following content: LoadModule proxy_module modules/mod_proxy.soLoadModule proxy_http_module modules/mod_proxy_http.soNameVirtualHost * ServerName abc.comProxyRequests OffOrder deny,allowAllow from allProxyPass / http://localhost:8080/ProxyPa***everse / http://localhost:8080/Order allow,denyAllow from all (2) Save the configuration file and restart the server.

Comparison between mod_jk and mod_proxy:

Feature mod_jk mod_proxyLoad balancing High level BasicManagement interface Yes NoCompilation Separate process Not required. By default comes with ApacheConfiguration Huge BasicProtocol AJP HTTP/HTTPS/AJPNode failure Advance NA
