一点孩子气本文记录一下在Ubuntu24.04下安装Nginx+Mysql+PHP
更新系统包列表
sudo apt update && sudo apt upgrade -y安装Nginx
sudo apt install nginx -y启动Nginx并设置开机自启
sudo systemctl start nginx
sudo systemctl enable nginx验证状态：
sudo systemctl status nginx # 确保状态显示为“active (running)”安装Certbot（用于Let’s Encrypt SSL证书）
sudo apt install certbot python3-certbot-nginx -y( 申请SSL证书
sudo certbot --nginx -d domain.com -d www.domain.com设置证书自动续订 # Let’s Encrypt证书有效期为90天，Certbot已配置自动续订。手动测试续订：
sudo certbot renew --dry-run安装 MySQL Server
sudo apt install mysql-server -y验证安装
systemctl status mysql
mysql --version启动并设置 MySQL 开机自启
sudo systemctl start mysql
sudo systemctl enable mysql运行安全配置向导
sudo mysql_secure_installation按提示完成以下设置：
- 设置 root 密码
- 移除匿名用户
- 禁止远程 root 登录
- 删除测试数据库
- 重新加载权限表
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?
Press y|Y for Yes, any other key for No: y
There are three levels of password validation policy:
LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
Skipping password set for root as authentication with auth_socket is used by default.
If you would like to use password authentication instead, this can be done with the "ALTER_USER" command.
See https://dev.mysql.com/doc/refman/8.0/en/alter-user.html#alter-user-password-management for more information.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
Dropping test database…
Success.
Removing privileges on test database…
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!登录 MySQL
sudo mysql -u root -p* MySQL 创建新用户并授权
CREATE USER '用户名'@'%' IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON . TO '用户名'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
EXIT;MySQL 配置远程访问（按情况设置）
修改配置文件：
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf将 bind-address 改为：
bind-address = 0.0.0.0重启MySQL：
sudo systemctl restart mysql安装 PHP 8.2
添加 PHP 8.2 的官方仓库（Ubuntu 24.04默认仓库未提供）
sudo add-apt-repository ppa:ondrej/php -y
sudo apt update安装 PHP 8.2 核心包
sudo apt install php8.2-cli php8.2-fpm php8.2-common --no-install-recommends -y
# 使用 --no-install-recommends 避免安装非必要依赖验证安装结果
dpkg --list | grep php8.2安装常用扩展（我要搭建 lsky.Pro）
sudo apt install \
php8.2-cli \
php8.2-fpm \
php8.2-mysql \
php8.2-redis \
php8.2-curl \
php8.2-gd \
php8.2-mbstring \
php8.2-xml \
php8.2-zip \
php8.2-bcmath \
php8.2-imagick \
imagemagick \
libmagickwand-dev \
--no-install-recommends -y验证安装
php -v启动并设置 php8.2-fpm 开机自启
sudo systemctl start php8.2-fpm
sudo systemctl enable php8.2-fpm检查 PHP 配置文件位置
php --ini查看已加载模块
php -m # 显示当前 PHP 已启用的模块安装其他扩展
#搜索可用扩展：
apt search php8.2-*
#使用 --no-install-recommends 避免引入无关依赖
sudo apt install php8.2-扩展名 --no-install-recommends -y配置 Nginx 使用 PHP-FPM
#通常在站点配置中添加
location ~ .php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php8.2-fpm.sock;
}重启 Nginx：
sudo systemctl restart nginx
