There are a number of posts on how to do this. I have created this post mostly for my own records so I know I will continue to have a record of what I have done.<\/p>\n
Ensure you have at least JDK 8, I have the RPM “java-1.8.0-openjdk.x86_64” installed by this point.<\/p>\n
Create a system user account to run tomcat:<\/p>\n
useradd -r tomcat –shell \/bin\/false<\/p>\n
Download the Tomcat 9 zip file, in my case this was “apache-tomcat-9.0.22.zip” which I downloaded to “\/var\/tmp” and then extract it and set permissions:<\/p>\n
cd \/var\/tmp
\nunzip apache-tomcat-9.0.22.zip -d \/opt
\nmv \/opt\/apache-tomcat-9.0.22 \/opt\/tomcat9
\nchown -R tomcat.tomcat \/opt\/tomcat9<\/p>\n
Now create a service file:<\/p>\n
\/etc\/systemd\/system\/tomcat.service<\/p>\n
For me this looked like:<\/p>\n
[Unit]\r\nDescription=Apache Tomcat 9\r\nAfter=syslog.target network.target\r\n\r\n[Service]\r\nUser=tomcat\r\nGroup=tomcat\r\nType=forking\r\nEnvironment=CATALINA_PID=\/opt\/tomcat9\/tomcat.pid\r\nEnvironment=CATALINA_HOME=\/opt\/tomcat9\r\nEnvironment=CATALINA_BASE=\/opt\/tomcat9\r\nExecStart=\/opt\/tomcat9\/bin\/startup.sh\r\nExecStop=\/opt\/tomcat9\/bin\/shutdown.sh\r\nRestart=on-failure\r\n\r\n[Install]\r\nWantedBy=multi-user.target<\/pre>\nNow set the correct permissions for the Tomcat startup script, enable the service and finally start the service:<\/p>\n
cd \/opt\/tomcat9\/bin
\nchmod 774 *.sh
\nsystemctl enable tomcat.service
\nsystemctl start tomcat.service<\/p>\nAt this point Tomcat is running and you should be able to access it on port 8080 so:<\/p>\n
http:\/\/centos7-base:8080\/<\/p>\n
