配置LAMP服務器的防火墻主要涉及打開必要的端口并確保防火墻規則的正確設置。以下是配置防火墻的步驟：
sudo yum install iptables-services
sudo vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
sudo service iptables restart
sudo chkconfig iptables on
sudo yum install firewalld
sudo systemctl start firewalld
sudo systemctl enable firewalld
sudo firewall-cmd --zone=public --add-port=80/tcp --permanent
sudo firewall-cmd --zone=public --add-port=3306/tcp --permanent
sudo firewall-cmd --reload
sudo firewall-cmd status
