2. Start tomat

Enter tomcat's bin directory and start tomcat:

[root@gts03 bin]# cd /mnt/software/tomcat-8.5.82-gtmall/bin
[root@gts03 bin]# ./startup.sh 

Using CATALINA_BASE:   /mnt/software/tomcat-8.5.82-gtmall

Using CATALINA_HOME:   /mnt/software/tomcat-8.5.82-gtmall

Using CATALINA_TMPDIR: /mnt/software/tomcat-8.5.82-gtmall/temp

Using JRE_HOME:        /mnt/software/jdk8

Using CLASSPATH:       /mnt/software/tomcat-8.5.82-gtmall/bin/bootstrap.jar:/mnt/software/tomcat-8.5.82-gtmall/bin/tomcat-juli.jar

Using CATALINA_OPTS:   

Tomcat started.

Enter IP:8080 in the browser. If the following interface appears, the installation is successful:

3. Installation as system service

All services in the CentOS system /etc/init.d/ correspond to a script in the directory. Creating a new service means creating a new script in the directory.

Create a new startup script here Tomcat.

vim /etc/init.d/tomcat-gtmall

#!/bin/sh -e
###必须添加，才能使用chkconfig命令设为自启动，2345参数表示,在哪些运行级别启动,启动序号61;关闭序号61；两位数字即可
#chkconfig:2345 61 61

##JDK目录
export JAVA_HOME=/mnt/software/jdk8
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.
export CATALINA_HOME=/mnt/software/tomcat-8.5.82-gtmall
 
case "$1" in
start)
        ${CATALINA_HOME}/bin/startup.sh
        exit 0
        ;;
stop)
        ${CATALINA_HOME}/bin/shutdown.sh
        exit 0
        ;;
debug)
        ${CATALINA_HOME}/bin/shutdown.sh
        ${CATALINA_HOME}/bin/catalina.sh run
        exit 0
        ;;
force-reload|restart)
        ${CATALINA_HOME}/bin/startup.sh
        ${CATALINA_HOME}/bin/shutdown.sh
        exit 0
        ;;
 
*)
        echo "Usage: /etc/init.d/tomcat-gtmall {start|stop|restart|force-reload|debug}"
        exit 1
        ;;
esac
 
exit 0

ESC:wq save and exit. Modify file permissions:

chmod o+x /etc/init.d/tomcat-gtmall

Add as startup:

chkconfig --add tomcat-gtmall
chkconfig --list

First stop the original service and start it as a service:

[root@gts03 bin]# ./shutdown.sh 

Using CATALINA_BASE:   /mnt/software/tomcat-8.5.82-gtmall

Using CATALINA_OPTS:   

[root@gts03 bin]# service tomcat-gtmall start

Visit IP:8080 again, you can access normally

Check whether tomcat is closed by ps -ef|grep java. If there is any execution, kill the process.
