在Debian系统中,LNMP指的是Linux、Nginx、MySQL和PHP。如果在启动过程中遇到问题,可以按照以下步骤进行排查和解决:
sudo systemctl start nginx
sudo systemctl status nginx
sudo tail -f /var/log/nginx/error.log
sudo systemctl start mysql
sudo systemctl status mysql
sudo tail -f /var/log/mysql/error.log
sudo systemctl start php-fpm
sudo systemctl status php-fpm
sudo tail -f /var/log/php-fpm/error.log
sudo nginx -t
sudo mysql_secure_installation
sudo nano /etc/php/7.x/fpm/pool.d/www.conf
sudo netstat -tuln | grep 80
sudo netstat -tuln | grep 3306
sudo ufw status
sudo ufw allow 'Nginx Full'
sudo systemctl restart nginx
sudo systemctl restart mysql
sudo systemctl restart php-fpm
sudo journalctl -xe
sestatus
sudo aa-status
df -h
free -h
通过以上步骤,您应该能够找到并解决Debian系统中LNMP启动失败的问题。如果问题仍然存在,请提供具体的错误信息以便进一步诊断。
