Java project online cloud server environment (2) - Tomcat installation and configuration
Tomcat choice:
It is best to choose the cloud server tomcat consistent with the tomcat version number running on the local project to avoid unnecessary problems.
Configuration steps:
1. First enter the cloud server to create a folder where tomcat is placed. Here, Xftp can be used on Windows systems and Transmit can be used on macOS systems to directly create new files. For example: /usr/local/tomcat
2. If you use the command line to create a new folder, do the following:
cd /usr/local
mkdir tomcat
3. Upload the downloaded tomcat package to the server /usr/local/tomcat (if you upload via ftp, go directly to the fourth step)
scp 本地文件绝对路径 [email protected]服务器IP地址:需要传入到服务的哪个文件下的绝对路径
4. Unzip the compressed package:
tar -zxvf apache-tomcat-9.0.55.tar.gz
5. Enter the bin directory of the unzipped folder:
cd /usr/local/tomcat/apache-tomcat-9.0.55/bin
6. Start the tomcat service:
./startup.sh
7. Stop the tomcat service:
./shutdown.sh
8. After starting the tomcat service, log in to the Alibaba Cloud official website, enter the ECS server console and find the network and security configuration security group:
9. Find the management rules, add the port manually, and add the corresponding port number according to the needs of your project:
10. Return to the tomcat configuration and check whether the firewall status is on:
systemctl status firewalld
11. If this error occurs,
Unit firewalld.service could not be found.it means that we do not have a firewall service. We need to download the firewall first:
yum install firewalld firewall-config
12. After downloading, start the firewall:
service firewalld start
13. The following are commonly used commands for firewalls:
启动防火墙：systemctl start firewalld
禁用防火墙：systemctl stop firewalld
重启防火墙：firewall-cmd --reload
查看防火墙状态：systemctl status firewalld
14. After starting the firewall, open the corresponding port number:
firewall-cmd --zone=public --permanent --add-port=8080/tcp
firewall-cmd --zone=public --permanent --add-port=8083/tcp
firewall-cmd --zone=public --permanent --add-port=3306/tcp
15. Refresh effect:
firewall-cmd --reload
16. Check the opened port number:
firewall-cmd --list-all
17. Restart the tomcat service:
./shutdown.sh
./startup.sh
18. Enter the IP of your server: 8080 to enter the tomcat page. At this time, tomcat is configured.
