Linux installation and configuration Tomcat

1. Download the Tomcat server

Link: https://pan.baidu.com/s/15wEXVJWdUUuXX1xRnXylUQ 
Extraction code: 1234

Official website download: Apache Tomcat® - Apache Tomcat 9 Software Downloads

2. Upload to Linux

I am using the upload tool that comes with FInalShell

3. Unzip the installation package

tar -zxvf apache-tomcat-9.0.63.tar.gz -C /usr/local/

Among them, I am used to putting the software I installed in the /usr/local directory

4. Start the service

sh startup.sh

 Enter the bin directory of Tomcat to start the service, and the running results are as follows

 5. Two methods to verify whether Tomcat starts successfully

  (1) Check the startup log

Check the next fifty lines of the log to see if there is an error message

tail -50 /usr/local/apache-tomcat-9.0.63/logs/catalina.out

(2) View process 

Check the existence of the process

ps -ef|grep tomcat

6. Access tTomcat in windows

Check your ip address: ip addr

ip addr

 

Then visit http://192.168.176.128:8080/ in Windows according to ip 

 It is normal to be unable to access, the Linux system firewall is automatically opened, so we need to set up a firewall

7. Set up a firewall

Firewall operation:

View firewall status: systemctl status firewalld
Temporarily shut down the firewall: systemctl stop firewalld

Permanently turn off the firewall: systemctl disable firewalld

Open the firewall: systemctl start firewalld

Open the specified port: firewall-cmd --zone=public --add-port=8080/tcp --permanent

Close the specified port: firewall-cmd --zone=public --remove-port=8080/tcp --permanent

Effective immediately: firewall-cmd --reload

View open ports: firewall-cmd --zone=public --list-ports

firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --reload
firewall-cmd --zone=public --list-ports

 

 8. Windows access Tomcat again
