mysqldump等工具备份数据库,复制配置文件和网站数据,以防升级出现问题。sudo apt update,CentOS/RHEL系统用sudo yum check-update或sudo dnf check-update。sudo apt upgrade、sudo apt full-upgrade;CentOS/RHEL系统用sudo yum upgrade或sudo dnf upgrade,必要时用sudo apt dist-upgrade处理依赖关系。sudo apt install --only-upgrade apache2升级Apache,用sudo apt install --only-upgrade mysql-server或sudo apt install --only-upgrade mariadb-server升级数据库,用sudo apt install --only-upgrade php*升级PHP。sudo systemctl restart apache2重启Apache,用sudo systemctl restart mysql或sudo systemctl restart mariadb重启数据库,若有PHP-FPM,用sudo systemctl restart php*-fp重启。apache2ctl -v、mysql --version、php -v等命令检查各组件版本,确认升级成功。
