主要安装步骤概览

详细安装操作流程

步骤1：环境准备与系统更新

# 更新系统软件包列表
sudo apt update
升级已安装的软件包
sudo apt upgrade -y
检查PHP是否已安装
php -v
检查MySQL/MariaDB状态
systemctl status mysql

步骤2：安装phpMyAdmin软件包

# 安装phpMyAdmin
sudo apt install phpmyadmin -y
如果使用Nginx，需要手动创建符号链接
sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

步骤3：配置Web服务器

# 对于Apache，重启服务
sudo systemctl restart apache2
对于Nginx，创建配置文件
sudo nano /etc/nginx/conf.d/phpmyadmin.conf

server {
    listen 80;
    servername your-domain.com;
    
    location /phpmyadmin {
        root /usr/share/;
        index index.php index.html index.htm;
        
        location ~ ^/phpmyadmin/(.+.php)$ {
            tryfiles $uri =404;
            root /usr/share/;
            fastcgipass unix:/var/run/php/php-fpm.sock;
            fastcgiindex index.php;
            fastcgiparam SCRIPTFILENAME $documentroot$fastcgiscriptname;
            include fastcgiparams;
        }
    }
}

步骤4：数据库安全配置

# 登录MySQL
sudo mysql -u root -p
创建phpMyAdmin专用用户
CREATE USER 'pmauser'@'localhost' IDENTIFIED BY 'securepassword';
授予必要权限
GRANT ALL PRIVILEGES ON . TO 'pmauser'@'localhost' WITH GRANT OPTION;
刷新权限
FLUSH PRIVILEGES;
退出MySQL
EXIT;

# 测试PHP配置
sudo systemctl restart php7.4-fpm  # 根据实际PHP版本调整
检查服务状态
sudo systemctl status apache2
sudo systemctl status nginx
sudo systemctl status mysql
