安装Nginx

# apt install nginx

申请SSL证书

# apt install certbot python2-certbot-nginx
# certbot --nginx

安装PHP

# apt install software-properties-common
# add-apt-repository ppa:ondrej/php
# apt-get update
# apt-get install php7.4 php7.4-cli php7.4-fpm php7.4-mysql php7.4-json php7.4-opcache php7.4-mbstring php7.4-xml php7.4-gd php7.4-curl php7.4-sqlite3

修改Nginx配置

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name www.myhost.cf myhost.cf;

        # Redirect http to https
        rewrite ^(.*)$  https://$host$1 permanent;
}

server {
        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm;

        server_name www.myhost.cf myhost.cf; # managed by Certbot

        listen [::]:443 ssl ipv6only=on; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/myhost.cf/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/myhost.cf/privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        location = /favicon.ico {
                log_not_found off;
                access_log off;
        }

        location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
        }

        location ^~ /wordpress/wp-content/database/ {
                deny all;
        }

        # pass PHP scripts to FastCGI server
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

                # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }
}

安装配置WordPress

为确保可以使用Sqlite，不使用最新版本的WordPress，而是使用5.4版。

# cd /var/www/html
# wget https://wordpress.org/wordpress-5.4.4.tar.gz
# tar zxvf wordpress-5.4.4.tar.gz
# wget https://github.com/aaemnnosttv/wp-sqlite-db/archive/v1.0.tar.gz
# tar zxvf v1.0.tar.gz wp-sqlite-db-1.0/src/db.php
# mv wp-sqlite-db-1.0/src/db.php wordpress/wp-content/
# rm -rf wp-sqlite-db-1.0

修改wordpress默认配置文件，以支持sqlite数据库：

# cp wordpress/wp-config-sample.php wordpress/wp-config.php
# nano wordpress/wp-config.php

/** The name of the database for WordPress */
define( 'DB_NAME', 'wordpress' );

/** MySQL database username */
define( 'DB_USER', '' );

/** MySQL database password */
define( 'DB_PASSWORD', '' );

/** MySQL hostname */
define( 'DB_HOST', 'localhost' );

/** Database Charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8' );

/** The Database Collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );

/** sqlite setting */
define('USE_MYSQL', false);

设置目录权限：

# chown -R www-data:www-data wordpress

最后，创建index.php文件，重定向至wordpress：

<?php
        if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
                $uri = 'https://';
        } else {
                $uri = 'http://';
        }
        $uri .= $_SERVER['HTTP_HOST'];
        header('Location: '.$uri.'/wordpress/');
        exit;
?>
