最近要搭个论坛，试了几个开源的论坛程序，这其中就有flarum，虽然最后我还是选择用discourse了，但flarum的安装步骤还是在这里记录下，留给需要的人。
安装nginx/mariadb/certbot：
apt -y update apt -y install nginx python3-certbot-nginx mariadb-server
添加sury的php存储库：
apt -y install curl apt-transport-https ca-certificates lsb-release curl -sSLo /usr/share/keyrings/deb.sury.org-php.gpg https://packages.sury.org/php/apt.gpg echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list apt -y update
安装php8.2：
apt -y install php8.2-common php8.2-fpm php8.2-curl php8.2-dom php8.2-gd php8.2-mbstring php8.2-mysql php8.2-zip
设置开机自启：
systemctl enable nginx mariadb php8.2-fpm
安装composer：
curl -sS https://getcomposer.org/installer | php mv composer.phar /usr/local/bin/composer
初始化mariadb：
mysql_secure_installation
登录到数据库：
mysql -u root -p
创建数据库和用户：
CREATE DATABASE flarum CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; GRANT ALL PRIVILEGES ON flarum.* TO flarum@localhost IDENTIFIED BY 'password'; FLUSH PRIVILEGES; quit
创建并进入到flarum目录：
mkdir -p /var/www/flarum cd /var/www/flarum
获取flarum以及安装所需的依赖、扩展：
composer create-project flarum/flarum .
修改目录权限和所有者：
chmod -R 775 /var/www/flarum chown -R www-data:www-data /var/www/flarum
新建nginx配置文件：
nano /etc/nginx/sites-available/flarum
写入如下配置：
server { server_name bbs.example.com; root /var/www/flarum/public; index index.php; client_max_body_size 0; location ~ .php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/var/run/php/php8.2-fpm.sock; } include /var/www/flarum/.nginx.conf; }
启用新的nginx配置：
ln -s /etc/nginx/sites-available/flarum /etc/nginx/sites-enabled/flarum
签发SSL证书：
certbot --nginx
访问你的域名填写各类信息完成安装：
如果需要修改php以及fpm相关的设置，例如文件上传大小、进程数量等：
nano /etc/php/8.2/fpm/pool.d/www.conf nano /etc/php/8.2/fpm/php.ini
重启phpfpm：
systemctl restart php8.2-fpm
