...
Unpack the tomcat tar.gz file into /opt/tomcat and set the file ownership and permissions.
| Code Block |
|---|
sudo mkdir /opt/tomcat cd /opt/tomcat sudo tar xvf /tmp/apache-tomcat-8*tar.gz --strip-components=1 |
...
This will have created the tomcat folders (conf, logs, webapps etc.) directly under /opt/tomcat.
Now to set the file ownership and permissions.
| Code Block |
|---|
cd /opt/tomcat
sudo chown -R tomcat webapps/ work/ temp/ logs/
sudo chgrp -R tomcat .
sudo chmod -R g+r conf
sudo chmod g+x conf |
Create a service wrapper
This stage creates a wrapper which allows tomcat to be managed as a service , which allows it to be stopped and started reliably.
Specifically, these instructions create a systemd service.
First, create a service definition file:
| Code Block |
|---|
sudo vi /etc/systemd/system/tomcat.service |
and paste the following into it:
| Code Block |
|---|
[Unit]
Description=Apache Tomcat Web Application Container
After=network.target
[Service]
Type=forking
Environment=JAVA_HOME=/opt/jdk/jdk1.8.0_85/jre
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms1000M -Xmx2000M -server -verbose:gc'
Environment='JAVA_OPTS=-Djava.awt.headless=true'
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh
WorkingDirectory=/opt/tomcat
User=tomcat
Group=tomcat
UMask=0007
RestartSec=10
Restart=always
[Install]
WantedBy=multi-user.target |
Before saving this,
- check that JAVA_HOME points to the version of java that you want to use
- check the CATALINE_OPTS -Xms and -Xmx memory settings
Now enable, then start the service:
| Code Block |
|---|
sudo systemctl daemon-reload
sudo systemctl start tomcat |
Lastly, check that the service started:
| Code Block |
|---|
sudo systemctl status tomcat |
