2. Unzip and execute the following command 


tar -zxvf apache-tomcat-9.0.0.M18.tar.gz

3. Rename the directory 


mv apache-tomcat-9.0.0.M18 tomcat_8080 (/path (Target path) )

4. Configure from startup, switch to bin directory of Tomcat to execute vi ES22en.sh, and press i to enter edit mode, copy and paste the following code 


#add tomcat pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
#add java opts
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"

After that, press the esc key, and press shift+ (" : "will appear in the lower left corner), and then enter wq to save and exit.

The last execution chmod +x setenv.sh  Ensure that file setenv.sh is executable.

5. Configuration service implement cd/usr/lib/systemd/system switch to the directory and execute vi tomcat. service (may also directly vi usr/lib systemd/system/tomcat service),
