FrankenPHP高负载下崩溃问题求助：需自动重启及兼容性排查

环境与问题现象 #

• 运行环境：配备10G显存、40G虚拟硬盘的虚拟机
• 核心问题：FrankenPHP在高负载场景下会崩溃并自动退出，切换至官方最新v1.2.5版本后问题仍复现
• 崩溃后影响：SSH无法连接，仅能通过重启虚拟机恢复系统可用性

部署与启动命令 #

wget https://github.com/dunglas/frankenphp/releases/download/v1.2.5/frankenphp-linux-x86_64
sudo chmod 777 ./frankenphp-linux-x86_64
sudo ./frankenphp-linux-x86_64 run --config caddyfile

尝试的自动重启脚本 #

free_mem=800001
while [ $free_mem -gt 800000 ]
do 
    free_mem=$(cat /proc/meminfo | grep '^MemAvailable' | awk '{ print $2 }')
    echo "Free_mem:"$free_mem
    while [ $free_mem -lt 800000 ]
    do 
        break 3
    done
    ./frankenphp-linux-x86_64 run --config caddyfile
done

注：原脚本存在语法错误，已修正free_mem赋值方式为标准命令替换格式

迁移背景与兼容性怀疑 #

• 从ATS迁移至FrankenPHP，PHP源码未做任何修改
• 使用PHProxy代理技术，PHP以源码形式运行无需编译，不清楚其依赖的系统库，怀疑该代理项目与FrankenPHP存在兼容性冲突

静态构建Dockerfile #

FROM dunglas/frankenphp:static-builder
# Copy your app
WORKDIR /go/src/app/dist/app
COPY . .
# Build the static binary
WORKDIR /go/src/app/dist/app
RUN rm -r dist/static-php-cli/watcher
RUN EMBED=dist/app/ . /build-static.sh

Caddyfile配置 #

{
    frankenphp
    order php_server before file_server
}

# Website root directory (adjust path as needed)
:80 {
    # Enable compression
    encode zstd br gzip

    # PHP program location, here please modify according to the actual root directory
    root * /tmp/frankenphp_1b73543cc848c8af8018b0cb0a54feee/public/

    # Return to empty page
    @blank path_regexp blank ^//blank/|^/blank/|^/favicon\.ico$
    route @blank {
        header Access-Control-Allow-Origin "*"
        header Cache-Control "public, max-age=31536000"
        respond "" 200
        abort
    }

    # Access the resource cache file directly
    @f1 path_regexp f1 ^/files/(\w)(\w\w)(\w{13})-\w-[\w\-]+(\.\w{2,4})$
    route @f1 {
        rewrite /temp/{http.regexp.f1.1}/{http.regexp.f1.2}/{http.regexp.f1.1}{http.regexp.f1.2}{http.regexp.f1.3}{http.regexp.f1.4}
    }
    @f2 path_regexp f2 ^/files/\w/\w{10}(\w)(\w\w)(\w{13})\w{6}/[\w/]+(\.\w{2,4})$
    route @f2 {
        rewrite /temp/{http.regexp.f2.1}/{http.regexp.f2.2}/{http.regexp.f2.1}{http.regexp.f2.2}{http.regexp.f2.3}{http.regexp.f2.4}
    }
    @tempfiles {
        path_regexp tempfiles ^/temp/\w/\w\w/\w{16}\.\w{2,4}$
    }
    route @tempfiles {
        # Don't process any content, pass directly to static file
        file_server
        abort
    }

    # If no matching file or directory is found, pass to unified entry
    @notFound {
        not file
    }
    route @notFound {
        rewrite /index.php?__nonematch__=1
    }

    # Forbidden directories or files
    @forbidden {
        not {
            path /robots.txt
        }
        path_regexp forbidden ^/(data|include|temp|plugin)/|\.db$|\.htaccess$|~\w+$|\.bak$|\.inc$|\.sh$|\.yaml$|\.ini$|\.bat$|\.dat$|\.txt$|\.lock$|\.conf$|\.inc\.php$|^/images/enc\.js$
    }
    respond @forbidden "" 404

    # PHP server
    php_server
}

注：原Caddyfile存在重复定义@forbidden的语法错误，已修正并统一规则
