升级到http 2.0后，老是报错503，谁能帮我解决一下？

错误日志：

[Mon Jul 19 11:03:26.351473 2021] [mpm_event:notice] [pid 9022:tid 140512076250176] AH00493: SIGUSR1 received.  Doing graceful restart

在 /etc/apache2/mods-enabled 我看到 http2.conf（如果我是对的）

通过 mod_macro 虚拟主机：

<Macro VHost $dir $domain>
<VirtualHost *:443>
    Protocols h2 http/1.1
    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/my.crt
    SSLCertificateKeyFile /etc/ssl/private/my.key

    AccessFileName .htaccess
    DocumentRoot $dir/$domain/httpdocs/

    ErrorLog $dir/$domain/error.log

    ServerName $domain
    ServerAlias www.$domain

    <Directory />
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    <Directory $dir/$domain>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
        Require all granted
    </Directory>
</VirtualHost>
</Macro>

【解决方案1】：

如果你遇到同样的情况，我希望它会有所帮助。我需要做的就是：

打开/etc/php/<version>/fpm/pool.d 并替换值

listen.owner = www-data
listen.group = www-data

/etc/apache2/envvars中的数据

export APACHE_RUN_USER=someuser
export APACHE_RUN_GROUP=someuser

结果将是：

listen.owner = someuser
listen.group = someuser

最后需要重启fpmsudo service php<version>-fpm start

顺便说一下，php-fpm 版本可能与您的php 版本不同。例如，输入 php -v 会显示 7.4。但是

 <?php phpinfo();

现在显示 8.0。所以我不得不选择这个目录/etc/php/8.0/fpm/pool.d
