Integration and Integration of Apache and Tomcat

I. First of all, I still quote a post of others, then do some instructions, and I will also ask you to correct it. II. Use Tomcat to do JSP servers alone, there will be problems in work efficiency, and the maximum number of concurrent connections that can withstand can also limit; Test, Tomcat is in the state of "zombie" when concurrent connection The subsequent request connection lost response. So now I have some "integration" solution: the HTML is clearly divided into labor, so that Tomcat only processes the JSP section, and other Web Server processing by Apache, IIS, which greatly saves Tomcat limited Work "thread". Of course, these J2EE servers such as IBM WebSphere, BEA WebLogic, JBoss will be a better solution, but only the application EJB will play the powerful features of these J2EE servers. So here, recommend Apache Tomcat's "gold combination". Find some information on the Internet, then do your own experiment, tossing for nearly one hour, finally got! The specific process is summarized as follows, I hope to help everyone: my operating environment: Windows2k Server SP4 J2SDK1.42 Apache2.049 Tomcat5.019 SQL Server2k ** Preparation Software: 1, Apache 2.0.49 2 Tomcat 5.0.19 3, JK2 connector (MOD_JK2.SO) ** Start installing: (The installation path here is optional, as long as you regard your actual situation is slightly modified) Apache is installed in H: / Apache / Under apache2, listening port 80; Tomcat is under H: /Apache/tomcat5.0, listening to port 8080; both are installed in Windows NT services.

Copy mod_jk2.so into the h: / apache / apache2 / modules directory: 1. Edit the h: /apache/apache2/conf/httpd.conf file, add: loadingModule JK2_Module Modules / Mod_jk2.so 2 Change AddDefaultCharset ISO-8859-1 to AddDefaultCharset GB2312 Automatically supports Chinese display; 3. Add: (This configuration can be modified according to your actual situation) ServerAdmin Pentium4xeon@etang.com DocumentRoot "H: /Apache/Tomcat5.0/webapps/ROOT" ServerName www.sdg.com ErrorLog logs / sdg.com-error_log CustomLog logs / sdg.com-access_log common * * Write the WORKERS2.PROPERTIES file and join the H: / apache / apache2 / conf directory, the content is as follows: [SHM] file = $ {serverroot} /logs/shm.file size = 1048576 #the socket channel: localhost: 8009] Port = 8009 Host = 127.0.0.1 #define the worker [AJP13: localhost: 8009] channel: localhost: 8009 #uri mapping [URI: / *. Jsp] worker = ajp13: localhost: 8009 ** Since Tomcat 5.019 has a JK2.Properties file, you don't have to write it yourself here. (Perhaps this is one of the benefits of high versions * ^ _ ^ *) ** Writing a normal HTML file (index.html) with a JSP file (Test.jsp), put it in h: /apore/tomcat5.0 / WebApps / root; Now it is best to restart your computer. After restarting, start Apache and Tomcat, http://www.sdg.com is the same as http://www.sdg.com:8080 --- displayed index.html; now you can test it Test.jsp, http://www.sdg.com/test.jsp, how, take it smoothly? ** Test the Tomcat connection pool section below, copy all files (HTML JSP JAVABEAN Servlet) to h: /apache/tomcat5.0/webapps/root, configure Tomcat's server.xml file, add a connection pool . In my, after testing, all functional parts can work.
