In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First, install jdk

1. Yum installation. I installed the jdk1.8 version.

The default installation path for jdk is / usr/lib/jvm/

2. Configure environment variables

Open this file and add the following configuration (note the version of jdk):

Export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64

Export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar.:$JAVA_HOME/lib/dt.jar.:$JAVA_HOME/lib/tools.jar

Export PATH=$PATH:$JAVA_HOME/bin

Replace the marked green one with your own jdk version! The rest of it is the same!

Save and exit

3. Make the environment variable effective source / etc/profile

4. Check whether java-version is installed successfully

Installation successful!

Second, install tomcat

1. Install tomcat online. I am the mkdir tomcat file installed in the / usr/local/ path. Install tomcat in this folder.

Execute the installation command, install online: wget http://apache.01link.hk/tomcat/tomcat-7/v7.0.94/bin/apache-tomcat-

7.0.94.tar.gz

2. Decompress tar-zxvf apache-tomcat-7.0.94.tar.gz (replace the green part with your own version)

3. After decompression, the directory structure of tomcat is as follows:

4. Go to the bin directory and execute the script. / start.sh to start tomcat

5. The default port number of tomcat is 8080. Check whether the port number starts successfully.

Netstat-tln

Tomcat started successfully!

Close tomcat and cut to the bin directory and execute. / shutdown.sh

Note:

If port 8080 is not started after netstat-tln execution, the port number may be disabled.

Modify the port number:

Vi / etc/sysconfig/iptables

Restart:

Service iptables restart

Done!
