[JAVA] Build Apache / Tomcat development environment on Cent OS 7


I would like to build a Web server environment that runs Apache Tomcat 9 on CentOS 7, which is a standard Linux server environment.

The following environment construction is introduced in this article.

Change log

2018.6.19 Added a little for Tomcat 9

Click here for articles up to the last time

The articles up to the last time have summarized the procedure for building a CentOS development server on GCP, so please read it as well.

Installation procedure

Work policy

  1. Use the package manager yum wherever possible.
  2. Install the official package to be as up-to-date as possible.
  3. Use Apache as the HTTP front server instead of Apache Tomcat alone.
  4. Use the JVM / JDK from Oracle.

Advance preparation

This procedure uses wget to download remote files. Install first if necessary.

yum -y install wget

Apache 2.4 installation

This item has the same procedure as last time, so please refer to the following. [Building Apache / PHP development environment on Cent OS 7](https://qiita.com/ariaki/items/2ec627a7567437f893ee#apache-24%E3%82%A4%E3%83%B3%E3%82% B9% E3% 83% 88% E3% 83% BC% E3% 83% AB)

JDK installation

When using OpenJDK

Install the JDK with the following command.

yum install java-1.8.0-openjdk-devel

When using Oracle JDK


First, download the latest version package for Linux x64 (jdk-8uxxx-linux-x64.tar.gz) locally from the URL below. http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Program placement

The following procedure is based on Java8u171, so please read the version number as appropriate.

mkdir /usr/java/
cd /usr/java/
tar zxf /path/to/jdk-8u171-linux-x64.tar.gz
ln -s jdk1.8.0_171 latest
echo -e "export JAVA_HOME=/usr/java/latest\nPATH=\$PATH:\$JAVA_HOME/bin" > /etc/profile.d/java.sh
source /etc/profile.d/java.sh

Execution path setting

Use the alternatives command to set which java command to launch by default.

alternatives --install /usr/bin/java java /usr/java/latest/bin/java 9999
alternatives --config java
alternatives --install /usr/bin/javac javac /usr/java/latest/bin/javac 9999
alternatives --config javac

After completing the settings, use the following command to check if the version you just installed is executed.

java -version
javac -version

Apache tomcat 9 installation

Download the latest version of Apache Tomcat from the official website as well.

Download and unpack

The following example will download the current latest version of Apache Tomcat 8.5.23, so please read as appropriate. The installation destination this time is "/ usr / tomcat8".

cd /usr/local/src
wget http://ftp.jaist.ac.jp/pub/apache/tomcat/tomcat-9/v9.0.8/bin/apache-tomcat-9.0.8.tar.gz
tar zxf apache-tomcat-9.0.8.tar.gz
mv apache-tomcat-9.0.8 /usr/tomcat9

basic configuration

Let's set environment variables using the following command.

echo -e "export CATALINA_HOME=/usr/tomcat9\nexport CATALINA_BASE=/usr/tomcat9" > /etc/profile.d/tomcat.sh
source /etc/profile.d/tomcat.sh

Operation check

You can check the version information and the execution JVM environment with the following command.


Let's confirm that the execution result is as follows.

Using CATALINA_BASE:   /usr/tomcat9
Using CATALINA_HOME:   /usr/tomcat9
Using CATALINA_TMPDIR: /usr/tomcat9/temp
Using JRE_HOME:        /
Using CLASSPATH:       /usr/tomcat9/bin/bootstrap.jar:/usr/tomcat9/bin/tomcat-juli.jar
Server version: Apache Tomcat/9.0.8
Server built:   Apr 27 2018 19:32:00 UTC
Server number:
OS Name:        Linux
OS Version:     3.10.0-862.3.2.el7.x86_64
Architecture:   amd64
JVM Version:    1.8.0_171-b10
JVM Vendor:     Oracle Corporation

User created

Create a user to run Apache Tomcat with the following command.

useradd -M -d /usr/tomcat9 tomcat
chown -R tomcat:tomcat /usr/tomcat9

Auto start setting

Manually generate a systemctl startup script with the following command.

echo "[Unit]
Description=Apache Tomcat Servlet Container
After=syslog.target network.target


" > /usr/lib/systemd/system/tomcat9.service

Start / stop with the following command.

systemctl start tomcat9
systemctl stop tomcat9
systemctl restart tomcat9

After completing the settings, use the following command to set automatic startup.

systemctl enable tomcat9

Apache → Tomcat linkage setting

To pass requests from Apache to Tomcat, you need to configure a ** reverse proxy **.

The following is a setting example to pass all requests under "/" to Tomcat.

echo "ProxyPass / ajp://localhost:8009/" > /etc/httpd/conf.d/proxy.conf

Once the above is done, let's restart Apache for the settings to take effect.

systemctl restart httpd

The above procedure completes the initial installation of Tomcat.
