This article will explain in detail what common configurations there are in Linux. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

one。 Install JDK under Linux

Method 1: use the yum command to install (generally there is no need to configure environment variables)

If the current Linux has JDK, check the current JDK version: java-version, or rpm-qa | grep jdk

Remove the current JDK:yum-y remove java-x.x.x

Check out all available JDK versions in the yum software library: yum search jdk

JDK version required for installation: yum install java-x.x.x,yum install java-x.x.x-devel

Method 2: use the installation package to install (generally need to configure environment variables)

Copy the installation package to the appropriate directory, for example, copy the installation package jdk-7u79-linux-x64.gz to the / usr/local/java directory

Extract the installation package: tar-zxvf jdk-7u79-linux-x64.gz, and generate the installation directory jdk1.7.0_79

Configure environment variables: add the following to / etc/profile

# set java environmentJAVA_HOME=/usr/local/java/jdk1.7.0_79CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarPATH=$JAVA_HOEM/bin:$PATHexport JAVA_HOME CLASS_PATH PATH

Execute the command source / etc/profile to make the configuration effective

two。 Linux install Tomcat

Before installing Tomcat, make sure that JDK is installed.

Copy the Tomcat installation package to the appropriate directory, for example, copy the installation package apache-tomcat-8.0.50.tar.gz to the / usr/local/tomcat directory

Go to the directory where the installation package is stored and extract the installation package: tar-zxvf apache-tomcat-8.0.50.tar.gz

Go to the bin directory under Tomcat and execute. / startup.sh or sudo. / startup.sh to start Tomcat

three。 Linux modifies Tomcat default JDK

Stop the Tomcat service

Go to the bin directory under Tomcat, and modify the catalina.sh and setclasspath.sh files in that directory, and add the following code to the headers of the two files:
