Flarum是一个免费的开放源代码和下一代论坛软件，它使您可以轻松地建立和发展成功的在线社区。它是基于PHP的简单，轻巧，快速且易于移动的软件。它具有丰富的功能集，包括优雅的用户界面，两窗格界面，无限滚动，浮动编辑器，完全响应等。

在本教程中，我们将说明如何在CentOS 8服务器上安装Flarum论坛。

要求

• 运行CentOS的服务器8。
• 指向您服务器IP的有效域名
• 在服务器上配置了root密码。

入门

开始之前，您需要在系统中安装EPEL和Remi存储库。首先，使用以下命令安装EPEL存储库：

dnf install epel-release -y

接下来，使用以下命令下载并安装Remi存储库：

wget http://rpms.remirepo.net/enterprise/remi-release-8.rpm
 rpm -Uvh remi-release-8.rpm

安装Nginx，MariaDB和PHP

首先，使用以下命令安装Nginx Web服务器和MariaDB服务器：

dnf install nginx mariadb-server -y

一旦安装了两个软件包，就需要启用php：remi-7.3模块来安装PHP 7.3。您可以使用以下命令启用它：

dnf module enable php:remi-7.3

接下来，使用以下命令安装具有其他必需依赖项的PHP：

dnf install php php-fpm php-common php-opcache php-pecl-apcu php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongodb php-pecl-redis php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml -y

安装完所有软件包后，启动Nginx，MariaDB和PHP-FPM服务，并使用以下命令使它们在系统重新引导后启动：

systemctl start nginx
 systemctl start mariadb
 systemctl start php-fpm
 systemctl enable nginx
 systemctl enable mariadb
 systemctl enable php-fpm

完成后，您可以继续下一步。

配置MariaDB数据库

默认情况下，MariaDB不安全。您可以使用以下脚本保护它：

mysql_secure_installation

回答所有问题，如下所示：

Enter current password for root (enter for none):
Set root password? [Y/n] Y
New password:
Re-enter new password:
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

完成后，使用以下命令登录MariaDB shell：

mysql -u root -p

在提示时提供您的root密码，然后使用以下命令为Flarum创建数据库和用户：

MariaDB [(none)]> CREATE DATABASE flarumdb;
 MariaDB [(none)]> GRANT ALL PRIVILEGES on flarumdb.* to 'flarum'@'localhost' identified by 'password';

接下来，刷新特权并使用以下命令从MariaDB shell退出：

MariaDB [(none)]> FLUSH PRIVILEGES;
 MariaDB [(none)]> EXIT;

完成后，您可以继续下一步。

为Nginx配置PHP-FPM

接下来，您将需要配置PHP-FPM以与Nginx一起使用。您可以通过编辑文件www.conf来实现：

nano /etc/php-fpm.d/www.conf

将用户名和组名从apache更改为nginx，如下所示：

user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx

接下来，找到以下行：

;listen = /run/php-fpm/www.sock

并将其替换为以下行：

listen = 127.0.0.1:9000

完成后保存并关闭文件。然后，重新启动PHP-FPM服务以应用更改：

systemctl restart php-fpm

安装Flarum

在安装Flarum之前，您需要在系统中安装Composer。

您可以使用以下命令进行安装：

curl -sS https://getcomposer.org/installer | php

安装完成后，您应该获得以下输出：

All settings correct for using Composer
Downloading...

Composer (version 1.9.2) successfully installed to: /root/composer.phar
Use it: php composer.phar

接下来，将Composer二进制文件移动到/ usr / local / bin目录并给予适当的权限：

mv composer.phar /usr/local/bin/composer
 chmod 755 /usr/local/bin/composer

接下来，将目录更改为Nginx文档根目录，并使用以下命令创建Flarum项目：

cd /var/www/html
 composer create-project flarum/flarum . --stability=beta

接下来，使用以下命令对Nginx Web根目录授予适当的权限：

chown -R nginx:nginx /var/www/html
 chmod -R 755 /var/www/html
 chown -R nginx:nginx /var/lib/php

完成后，您可以继续下一步。

为Flarum配置Nginx

接下来，您将需要为Nginx创建一个Nginx虚拟主机配置文件。您可以使用以下命令创建它：

nano /etc/nginx/conf.d/flarum.conf

添加以下行：

server {
    listen   80;
    server_name  flarum.example.com;

# note that these lines are originally from the "location /" block
root   /var/www/html/public;
index index.php index.html index.htm;

location / { try_files $uri $uri/ /index.php?$query_string; }
location /api { try_files $uri $uri/ /api.php?$query_string; }
location /admin { try_files $uri $uri/ /admin.php?$query_string; }

location /flarum {
    deny all;
    return 404;
}

location ~ /.php$ {
    try_files $uri =404;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

location ~* /.html$ {
    expires -1;
}

location ~* /.(css|js|gif|jpe?g|png)$ {
    expires 1M;
    add_header Pragma public;
    add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
gzip on;
gzip_http_version 1.1;
gzip_vary on;
gzip_comp_level 6;
gzip_proxied any;
gzip_types application/atom+xml
           application/javascript
           application/json
           application/vnd.ms-fontobject
           application/x-font-ttf
           application/x-web-app-manifest+json
           application/xhtml+xml
           application/xml
           font/opentype
           image/svg+xml
           image/x-icon
           text/css
           #text/html -- text/html is gzipped by default by nginx
           text/plain
           text/xml;
gzip_buffers 16 8k;
gzip_disable "MSIE [1-6]/.(?!.*SV1)";
   }

完成后，保存并关闭文件。接下来，您需要在nginx.conf文件中增加hash_bucket的大小。

您可以通过编辑文件/etc/nginx/nginx.conf来实现：

nano /etc/nginx/nginx.conf

在最后一行的上方添加以下行：

server_names_hash_bucket_size 64;

保存并关闭文件。然后，使用以下命令检查Nginx是否存在语法错误：

nginx -t

您应该看到以下输出：

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

最后，重新启动Nginx和PHP-FPM服务以应用更改：

systemctl restart php-fpm
 systemctl restart nginx

配置SELinux和防火墙

首先，您将需要创建防火墙规则以允许来自外部网络的HTTP和HTTPS服务。您可以使用以下命令允许它：

firewall-cmd --permanent --add-service=http

firewall-cmd --permanent --add-service=https
 firewall-cmd --reload

默认情况下，CentOS 8中启用了SELinux。因此，您需要为Flarum配置SELinux才能正常工作。您可以使用以下命令配置SELinux：

setsebool httpd_can_network_connect on -P

完成后，您可以继续下一步。

访问Flarum Web UI

现在，打开Web浏览器并输入URL http://flarum.example.com。您将被重定向到以下页面：

提供您的论坛名称，数据库详细信息，管理员用户名，密码，然后单击“ 安装 Flarum”按钮。成功完成安装后，您应该在以下页面中看到Flarum仪表板：

让我们加密SSL保护Flarum

Flarum现在已安装和配置。是时候使用“免费加密SSL”来保护它了。

为此，您需要在服务器上下载certbot客户端。您可以通过运行以下命令下载并设置正确的权限：

wget https://dl.eff.org/certbot-auto
 mv certbot-auto /usr/local/bin/certbot-auto
 chown root /usr/local/bin/certbot-auto
 chmod 0755 /usr/local/bin/certbot-auto

现在，运行以下命令为flarum网站获取并安装SSL证书。

certbot-auto --nginx -d flarum.example.com

上面的命令将首先在服务器上安装所有必需的依赖项。安装后，将要求您提供一个电子邮件地址并接受服务条款，如下所示：
