To install the JDK:

Download binary package on official website

# chmod +x jdk-6u45-linux-i586-rpm.bin# give Execute permissions #./jdk-6u45-linux-i586-rpm.bin# execution

Installed by default in the/usr/java directory

Apache Installation:

To use Mod_proxy to connect to a Tomcat instance, Apache has already loaded mod_proxy, Mod_proxy_http, MOD_PROXY_AJP, and Proxy_balancer_ Module (used when implementing the Tomcat cluster)

#./configure--prefix=/usr/local/apache--sysconfdir=/etc/httpd--enable-so--enable-rewirte--enable-ssl-- enable-cgi--enable-cgid--enable-modules=most--enable-mods-shared=most--enable-mpms-shared=all--with-mpm=event- -WITH-APR=/USR/LOCAL/APR--with-apr-util=/usr/local/apr-util--enable-proxy--enable-proxy-http--ENABLE-PROXY-AJP --enable-proxy-balancer# make# make install# vim/etc/rc.d/rc.local#/usr/local/apache/bin/apachectl start# vim/etc/ profile.d/apache.sh export path= $PATH:/usr/local/apache/bin

Configure Apache to connect to Tomcat via the Mod_proxy module:

# Vim Httpd.conf

#DocumentRoot "/usr/local/apache/htdocs"# comment out, open the virtual host

include/etc/httpd/extra/httpd-proxy.conf# Add one line at a time point to stand-alone configuration file

# vim/etc/httpd/extra/httpd-proxy.conf# Edit configuration file, add the following content

<virtualhost *:8080>

Proxyvia OFF

Proxyrequests OFF

proxypass/http://192.168.8.16:8080/

proxypassreverse/http://192.168.8.16:8080/

<proxy *>

Require all granted

</Proxy>

<location/>

Require all granted

</Location>

</VirtualHost>

Description of the above Apache directive:

Proxypreservehost {on| OFF}: If this feature is enabled, the agent sends the host: line from the user request message to the backend server instead of using the server address specified by Proxypass. If you want to support virtual hosts in a reverse proxy, you need to turn this on, or you won't have to turn on this feature.

Proxyvia {on| Off| full| Block}: Used to control whether the HTTP header uses via:, which is primarily used to control the flow of proxy requests in the multilevel proxy. The default is off, which means that the feature is not enabled; On indicates that each request and response message is added via:;full indicates that each via: Row adds the current Apache server version number information, and block means that the Via: in each proxy request message will be removed.

proxyrequests {on| OFF}: Whether to turn on the functionality of Apache forward proxy; When enabled, the Mod_proxy_http module must be enabled in order to proxy the HTTP protocol. Also, if you set proxypass for Apache, you must set proxyrequests to OFF.

Proxypass [path]!| URL [key=value key=value ...] : Associates a backend server URL with a virtual path to the current server as the path to provide the service, path is a virtual path on the current server, and the URL is a URL path on the back-end server. You must set the value of proxyrequests to OFF when you use this directive. It is important to note that if path ends with "/", the corresponding URL must also end with "/" and vice versa.

In addition, the Mod_proxy module is httpd
