Detailed introduction to installing and configuring tomcat under Linux

Tomcat is a lightweight application server that is commonly used in small and medium-sized systems and situations where there are not many concurrent access users. It is the first choice for developing and debugging JSP programs. For a beginner, you can think of it this way: when the Apache server is configured on a machine, it can be used to respond to access requests for HTML pages.

First you need toinstallconfigure the JDK. Here is a brief review.LinuxUse root identity to create a jvm folder in the /opt/ folder, and then use tar - zxvf jdk-8u121-linux-x64.tar.gz -C /opt/jvm/ Extract the file to jvm, then modify the /etc/profile file as root and add the last four lines:

export JAVA_HOME=/opt/jvm/jdk1.8.0_121
export JRE_HOME=${JAVA_HOME}/jre
export 
CLASS
PATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

SaveExit.

After configuring the environmentvariables, you can use the sudo update-alternatives --config java command to view existing environment variables.

java -version tests whether the JDK is installed successfully.

Let’s get to the point and install and configure tomcat.
