How to separate static and dynamic state by combining Apache with Tomcat

Experimental environment

• Apache and Tomcat are both installed on the host with IP address 192.168.153.136
• The host operating system is centos7
• Before the experiment, turn off the firewall, command: systemctl stop firewalld
• Disable seliunx, command: setenforce 0
• The experimental result is that Apache processes html static resources and Tomcat processes jsp dynamic resources

1. Install and start Apache

1.1 Installation

 yum -y install httpd

1.2 Startup

systemctl start httpd

2. Install and start tomcat

2.1 Install JDK

rpm -ivh jdk-8u131-linux-x64_.rpm

2.2 Verify that JDK is installed successfully

[root@host-136 ~]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

2.3 Unzip the Tomcat installation package and move it to the /opt directory

2.3.1 Decompression

tar xzf apache-tomcat-8.5.35.tar.gz

2.3.2 Mobile name change

mv apache-tomcat-8.5.35 /opt/tomcat

2.4 Start the service

/opt/tomcat/bin/startup.sh

3. Install the connector tomcat-connectors source code

3.1 Installation Required Environment

yum -y install httpd-devel gcc gcc-c++

3.2 Decompression

tar zxf tomcat-connectors-1.2.48-src.tar.gz

3.3 Detect environment and configure

cd tomcat-connectors-1.2.48-src/native

./configure --with-apxs=/usr/bin/apxs

3.3 Compile and install

make && make install

3.4 Verify installation is successful

[root@host-136 native]# ll /etc/httpd/modules/mod_jk.so
-rwxr-xr-x. 1 root root 1565864 Jan 6 09:32 /etc/httpd/modules/mod_jk.so

4. Create a test page

4.1 Static Pages

vim /var/www/html/index.html

<h1>static_page_from_apache</h1>

4.2 Dynamic Pages

vim /opt/tomcat/webapps/ROOT/test.jsp

<h1>dynamic_page_from_tomcat</h1>

5. Configure the jk module to integrate Apache with tomcat

5.1 Copy the configuration file

cd tomcat-connectors-1.2.48-src/conf/
cp httpd-jk.conf /etc/httpd/conf.d/
cp workers.properties /etc/httpd/conf/

5.2 Modify the workers.properties configuration file

vim /etc/httpd/conf/workers.properties

5.2.1 Change port to 8009

Note: The Connector AJP Port is used to listen for requests on the AJP (Apache JServ Protocol) protocol. It is usually used to integrate other HTTP servers such as Apache Server. The default value is 8009.

5.2.2 Comment or delete the lines 86 87 88 89 96

5.3 Modify the httpd-jk.conf configuration file

vim /etc/httpd/conf.d/httpd-jk.conf

Remove the comments from line 94 and modify it as follows

6. Restart Apache service

systemctl restart httpd

7. Access page test

7.1 Enter ip/index.html in the browser to test the static page

7.2 Enter ip/test.jsp in the browser to test the dynamic page
