First, Nginx+tomcat host implementation

1. Host Planning

Nginx Host	172.18.12.20
Tomcat Host	172.18.12.21

2. Install the Tomcat host and deploy a simple test page

# yum Install java-1.7.0-openjdk java-1.7.0-openjdk-devel# vim/etc/profile.d/java.sh

Java_home=/usr

Export Java_home

# . /etc/profile.d/java.sh

3. Install Tomcat

# yum install-y Tomcat tomcat-lib Tomcat-webapps Tomcat-admin-webapps

4: Deploy a test page

# mkdir/var/lib/tomcat/webapps/myapp# mkdir/var/lib/tomcat/webapps/myapp/{classes,lib,web-inf,meta-inf}# mkdir/ var/lib/tomcat/webapps/myapp/index.jsp# vim/var/lib/tomcat/webapps/myapp/index.jsp

<%@ page language= "java"%>

<body>

<tr>

<td>session id</td>

<% Session.setattribute ("magedu.com", "magedu.com"); %>

</tr>

<tr>

<td>created on</td>

</tr>

</table>

</body>

5. Start Tomcat

# Systemctl Start Tomcat

7.nginx Host Installation Configuration

# yum Install-y nginx# vim/etc/nginx/nginx.conf

Location ~* \. (Jsp|do) {

Proxy_pass http://172.18.12.21:8080;

}

# nginx-t# Nginx

Second, Apache+tomcat host implementation

Host planning

Apache Host	172.18.12.20
Tomcata Host	172.18.12.21

In order not to let Nginx host affect our experiment, we first uninstall Nginx, then install Apache

#yum Remove nginx# yum install-y httpd

Apache Back-end host has three kinds of implementations we separate to one by one demo, note here we are based on virtual host implementation

2. Note Center Host

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

#DocumentRoot "/var/www/html"

3. The first method of realization

Use HTTPD to bring the proxy module proxy_http_module based on the HTTP protocol to implement

Writing a httpd configuration file

# vim/etc/httpd/conf.d/http_proxy.conf

ServerName dy.magedu.com

Proxyrequests off forward Proxy

Proxyvia on indicates which host agent refers to the backend host's

Proxypreservehost on turn off other redirected host names

Require all granted authorized agent for all access requests

</Proxy>

proxypass/http://172.18.12.21:8080/

proxypassreverse/http://172.18.12.21:8080/

Require all granted

</Location>

</VirtualHost>

Test syntax and overload httpd to make the configuration file effective

#httpd-t#systemctl Reload httpd

The second method uses HTTPd's own module proxy_ajp_module to achieve

The difference between this implementation and the first is that different protocols are used, and we can make use of the previous configuration file just to modify the protocol and port.

# mv/etc/httpd/conf.d/http_proxy.conf/etc/httpd/conf.d/ajp_proxy.conf

ServerName dy.magedu.com

Proxyrequests OFF

Proxyvia on

Proxypreservehost on

Require all granted

</Proxy>

proxypass/ajp://172.18.12.21:8009/

proxypassreverse/ajp://172.18.12.21:8009/

Require all granted

</Location>

</VirtualHost>

Third use of third-party module MOD_JK implementation

To prevent the original configuration file from affecting our experiment rename the original configuration file

# Mv/etc/httpd/conf.d/ajp_proxy.conf{,.bak}

1. Compile and install MOD_JK

# yum Groupinstall-y "Development tools" "Server Platform Development" # Yum install httpd-devel# tar-xf tomcat-connector S-1.2.40-src.tar.gz # CD tomcat-connectors-1.2.40-src/native/#./configure--with-apxs=/usr/bin/apxs#make && Make install

2. Provide the MOD_JK configuration file

# vim/etc/httpd/conf.d/mod_jk.conf

LoadModule Jk_module modules/mod_jk.so

Jkworkersfile/etc/httpd/conf.d/workers.properties

Jklogfile Logs/mod_jk.log

Jkloglevel Debug

Jkmount/* Tomcata

Jkmount/jk_status StatA

# vim/etc/httpd/conf.d/workers.properties

Worker.list=tomcata,stata

Worker. tomcata.host=172.18.12.21

Worker. tomcata.port=8009

Worker. Tomcata.type=ajp13

Worker. Stata.type=status

#httpd-T #systemctl restart httpd
