# 放开8080端口
firewall-cmd --permanent --zone=public --add-port=8080/tcp
# 重载防火墙配置，使上一行命令生效
firewall-cmd --reload
# 测试端口是否已经放开
firewall-cmd --zone=public --query-port=8080/tcp
Attachment: You can check the running status with the following command:
# 根据关键字查看进程
ps -aux | grep tomcat
# 查看端口使用状况
netstat -nalp | grep 8088
# 无法识别 netstat 命令时可以通过以下命令进行下载
yum install net-tools
# 监听日志输出
cd /usr/local/tomcat/apache-tomcat-9.0.43/logs/
