安装

首先安装 PHP 8.0、SQLite 扩展，以及一些和 handsome 主题相关的扩展。

$ sudo add-apt-repository ppa:ondrej/php
$ sudo apt install php8.0-fpm php8.0-sqlite3 php8.0-mbstring php8.0-curl
$ systemctl status php8.0-fpm

配置 PHP

$ grep ^listen /etc/php/8.0/fpm/pool.d/www.conf
listen = /run/php/php8.0-fpm.sock
listen.owner = www-data
listen.group = www-data

配置 Nginx

$ sudo rm -f /etc/nginx/sites-available/*
$ sudo rm -f /etc/nginx/sites-enabled/*
$ sudo vi /etc/nginx/conf.d/runsisi.com.conf
server {
    listen 80;
    listen 443 ssl;
    server_name www.runsisi.com;
    ssl_certificate /home/runsisi/runsisi.com/certs/runsisi.com.crt;
    ssl_certificate_key /home/runsisi/runsisi.com/certs/runsisi.com.key;

    return 301 https://runsisi.com$request_uri;
}

server {
    listen 80;
    server_name runsisi.com;

    return 301 https://runsisi.com$request_uri;
}

server {
    listen 443 ssl;
    server_name runsisi.com;
    ssl_certificate /home/runsisi/runsisi.com/certs/runsisi.com.crt;
    ssl_certificate_key /home/runsisi/runsisi.com/certs/runsisi.com.key;

    root /home/runsisi/runsisi.com/typecho;

    location / {
        include fastcgi.conf;

        ### comment out these overrides if pseudo static is disabled
        fastcgi_param SCRIPT_FILENAME $document_root/index.php;
        fastcgi_param SCRIPT_NAME /index.php;

        fastcgi_index index.php;
        fastcgi_pass unix:/run/php/php8.0-fpm.sock;
    }

    location /admin/ {
        include fastcgi.conf;

        fastcgi_index index.php;
        fastcgi_pass unix:/run/php/php8.0-fpm.sock;
    }

    location ~ [^/]\.php(/|$) {
        include fastcgi.conf;

        fastcgi_pass unix:/run/php/php8.0-fpm.sock;
    }

    location ~* ^.+\.(gif|jpeg|jpg|png|xml|txt|css|js|svg|ico|json|eot|ttf|woff|woff2|swf)$ {
        expires max;
    }
}

当然，这里对于 URL 的处理有多种，网上常见的如下所示：

location / {
    index index.php;

    if (!-e $request_filename) {
        rewrite ^(.*)$ /index.php$1 last;
    }

    try_files $uri $uri/ =404;
}

或者：

location / {
    index index.php;

    try_files $uri $uri/ /index.php$uri$is_args$args;
}

配置 Typecho

$ cd typecho/usr/
$ mkdir sqlitedb uploads backups
$ sudo chown www-data.www-data sqlitedb/ uploads/ backups/

然后访问首页按照 Typecho 的提示进行配置即可。

最后，在 设置/永久链接 中启用 地址重写功能 功能。

打开 PHP 调试日志

为了定位问题，可以使用 PHP 的 error_log() 接口打印相关的信息，当然前提是打开相关的调试日志：

$ grep ^error_log /etc/php/8.0/fpm/php-fpm.conf
error_log = /var/log/php8.0-fpm.log
$ grep ^catch /etc/php/8.0/fpm/pool.d/www.conf
catch_workers_output = yes

使用 PhpStorm 调试 PHP

如果简单的日志打印难以定位问题，可以使用调试工具进行精准定位：

$ sudo apt install php8.0-xdebug

$ cat /etc/php/8.0/fpm/conf.d/20-xdebug.ini
zend_extension=xdebug.so

xdebug.mode=debug
xdebug.start_with_request=trigger
xdebug.client_host=127.0.0.1
xdebug.client_port=9003
