1. What is Tomcat

Tomcat is a software used to parse a JSP program, a Web container;

Tomcat is a core project of the Apache Software Foundation (Apache Software Foundation) Jakarta Project, developed by Apache, Sun, and other companies and individuals.

Tomcat is a lightweight application server that is widely used in small and medium-sized systems and concurrent access users, and is the first choice for developing and debugging JSP programs.

2. To run Tomcat, you must first install the JDK

Download the JDK on the official website to extract:

TAR-ZXVF jdk-8u31-linux-i586.tar.gz

MV Jdk1.8.0_31/usr/local/jdk1.8.0_31

vim/etc/profile.d/java.sh//Add local environment variables to the following configuration:

Java_home=/usr/local/jdk1.8.0_45

Java_bin=/usr/local/jdk1.8.0_45/bin

Jre_home=/usr/local/jdk1.8.0_45/jre

Path= $PATH:/usr/local/jdk1.8.0_45/bin:/usr/local/jdk1.8.0_45/jre/bin

classpath=/usr/local/jdk1.8.0_45/jre/lib:/usr/local/jdk1.8.0_45/lib:/usr/local/jdk1.8.0_45/jre/lib/ Charsets.jar

Let java.sh enter into force execution #. /etc/profile.d/java.sh

If the above configuration succeeds, the following command can see the Java version:

[Email protected] src]# java-version

Java Version "1.8.0_31"

Java (TM) SE Runtime Environment (build 1.8.0_31-b13)

TAR-ZXVF apache-tomcat-7.0.62.tar.gz

MV Apache-tomcat-7.0.62/usr/local/tomcat

Cp-pv/usr/local/tomcat/bin/catalina.sh/etc/init.d/tomcat

"/usr/local/tomcat/bin/catalina.sh", "/etc/init.d/tomcat"
