Second, installation TOMCAT7

#wget http://apache.mirror.digitalpacific.com.au/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz

#tar zxvf xxx After decompression is a binary file, no need to install. Move the directory directly to the/usr/local directory

#mv Xxx/usr/local/tomcat

#vim/usr/local/tomcat/bin/catalisna.sh setting environment variables in the Tomcat startup script

JAVA_HOME=/USR/JAVA/JDK1.8.0XX make IT support Java, add this line

#vim/etc/profile

Path= $JAVA _home/bin:/usr/local/tomcat/bin/: $PATH Setting environment variables

Exits the current shell, and the configuration takes effect after re-entry

Or

#. /etc/profile make the new environment variable effective

Iii. Integration of Tomcat+apache

Three ways of Integration:

JK Way

Http_proxy Way

Ajp_proxy Way

Modules required for Http_proxy mode:

Mod_proxy.so and Mod_prxy_http.so

The default mod_proxy.so is already installed, just install the mod_proxy_http.so module

#ls/usr/lib64/httpd/modules/mod_proxy.http.so

#ls/usr/lib64/httpd/modules/mod_proxy.so

Add the module to the httpd.conf configuration file

#vim/etc/httpd/conf/httpd.conf

LoadModule proxy_http_module modules/mod_proxy_http.so

#service httpd restart Restart Apache Service

Test:

Browser input: Server IP
