Java+Tomcat environment deployment and installation process diagram

Next, I will install Java+Tomcat on Centos7. There are many articles on the Internet, and I have some problems in deployment. The following is an installation process I summarized myself!

Install Java Environment

First, we go to the Java official website to download JDK. Here I download the jdk1.8 version.

https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Click Accept License Agreement and select the version to download. You need to register an Oracle account to log in and download!

Copy the downloaded jdk package to the Centos7 root directory. It is recommended to use WinSCP

Create a Java installation directory

mkdir -p /usr/local/java

Unzip the jdk package to the java installation directory

tar -zxvf jdk-8u211-linux-x64.tar.gz -C /usr/local/java/

Configuring environment variables

vim /etc/profile.d/java.sh

export JAVA_HOME=/usr/local/java/jdk1.8.0_211
export CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
export PATH=$PATH:$JAVA_HOME/bin

Make the configuration take effect immediately

source /etc/profile

Verify that the Java environment is configured successfully

Install Tomcat environment

Download the installation package from the official website: https://tomcat.apache.org/

Here I choose Tomcat8 Archives to view historical versions

Here I choose version v8.5.5. Remember not to enter the src directory to download the installation package. You will encounter the problem of not finding bootstarp.jar in the bin directory. Enter the bin directory and download the code package.

Unzip to the installation directory

tar -zxvf apache-tomcat-8.5.5.tar.gz -C /usr/local/

Creating a Soft Link

cd /usr/local/
ln -sv apache-tomcat-8.5.5 tomcat

Configuring environment variables

vim /etc/profile.d/tomcat.sh

CATALINA_BASE=/usr/local/tomcat
PATH=$CATALINA_BASE/bin:$PATH
export PATH CATALINA_BASE

Make the configuration take effect

source /etc/profile.d/tomcat.sh

Check the tomcat version status

Enter the bin directory of tomcat

cd /usr/local/tomcat/bin/

Grant Permission

chmod 755 *

View configuration information

./catalina.sh version

Start Tomcat service

./startup.sh

If the above content appears, it means success. Now visit ip:8080 to see
