我无法从 apache 获取环境变量

在 Centos 8 上，我在 VirtualHost 配置中添加了一个 SetEnv：

<VirtualHost *:XXXX>
    Alias /static/ /opt/industrialisation/xxxx/xxxx/xxxx/
    <Directory /opt/industrialisation/xxx/xxxx/>
        Require all granted
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>
    WSGIDaemonProcess myproject python-home=/opt/venv/venv-xxxxx python-path=/opt/industrialisation/xxxx/xxxxx/
    WSGIProcessGroup myproject
    WSGIScriptAlias / /opt/industrialisation/xxxx/xxxx/xxxxx/wsgi.py
    SetEnv VARIABLE_NAME variable_value
</VirtualHost>

我停止并启动 httpd 服务：

[root@xxxxx ~]# systemctl stop httpd.service
[root@xxxxx ~]# systemctl start httpd.service

服务运行良好：

[root@xxxxxxx ~]# systemctl status httpd.service

我检查变量是否可用但不可用：

[root@xxxxxxx ~]# cat /proc/49075/environ | tr '\0' '\n'
LANG=C
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
NOTIFY_SOCKET=/run/systemd/notify
INVOCATION_ID=a3e117c7287b445b9b9932f7ec8883b1
JOURNAL_STREAM=9:220753

我还认为系统变量（如 HOSTNAME）将可用于进程 httpd，但我只看到这 5 个变量。

这正常吗？是不是我的 proc 检查有问题？我很困惑。
