Ubuntu服务器Apache+WSGI部署双Django应用故障求助

我在Ubuntu VPS上尝试托管第二个域名domain2，已知单IP可托管多域名，但遇到问题——第一个域名domain1.tn可正常访问，第二个域名domain2却指向Apache默认页面。

我的Apache2配置文件/etc/apache2/sites-enabled/000-default-le-ssl.conf内容如下：

Define wsgi_daemon1 "domain1"
Define wsgi_daemon2 "domain2"

<IfModule mod_ssl.c>

<VirtualHost *:443>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Alias /static /home/my_linux_user/myproject/static
    <Directory /home/my_linux_user/myproject/static>
        Require all granted
    </Directory>
    <Directory /home/my_linux_user/myproject/myproject>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>    
    <IfDefine !wsgi_init>
        WSGIDaemonProcess ${wsgi_daemon1} python-path=/home/my_linux_user/myproject python-home=/home/my_linux_user/myproject/myprojectenv
        WSGIProcessGroup ${wsgi_daemon1}
        WSGIScriptAlias / /home/my_linux_user/myproject/myproject/wsgi.py    
        Define wsgi_init 1
    </IfDefine>

ServerName domain1.tn
SSLCertificateFile /etc/letsencrypt/live/domain1.tn/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/domain1.tn/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

<VirtualHost *:443>

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error_project2.log
    CustomLog ${APACHE_LOG_DIR}/access_project2.log combined

    Alias /static /home/my_linux_user/project2/static
    <Directory /home/my_linux_user/project2/static>
        Require all granted
    </Directory>
    <Directory /home/my_linux_user/project2/django_project>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>    
    <IfDefine !wsgi_init>
        WSGIDaemonProcess ${wsgi_daemon2} python-path=/home/my_linux_user/project2 python-home=/home/my_linux_user/project2/project2ENV
        WSGIProcessGroup ${wsgi_daemon2}
        WSGIScriptAlias / /home/my_linux_user/project2/django_project/wsgi.py    
        Define wsgi_init 1
    </IfDefine>


ServerName domain2
SSLCertificateFile /etc/letsencrypt/live/domain2/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/domain2/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

</IfModule>

我已尝试以下操作：

• 执行apachectl restart和apachectl graceful重启Apache2
• 确认DNS配置正常解析
• 单独配置虚拟主机托管静态页面可正常工作，但添加WSGI配置后失效
• 用apache2ctl -S查看已启用站点，输出如下：

请问配置更改是否需要时间生效？（部署第一个域名时无此情况）若无需等待，恳请提供解决建议。

解决建议 #

你的问题核心在于<IfDefine !wsgi_init>的条件判断逻辑：第一个虚拟主机加载时已执行Define wsgi_init 1，导致第二个虚拟主机的该条件不成立，WSGI守护进程、进程组及脚本别名的配置完全未生效，最终只能使用默认的DocumentRoot /var/www/html（即Apache默认页面）。

修复步骤：

1. 移除全局条件控制块：删除两个虚拟主机内的<IfDefine !wsgi_init>和Define wsgi_init 1代码块，直接保留各自的WSGI配置。修改后的第二个虚拟主机WSGI部分应为：

WSGIDaemonProcess ${wsgi_daemon2} python-path=/home/my_linux_user/project2 python-home=/home/my_linux_user/project2/project2ENV
WSGIProcessGroup ${wsgi_daemon2}
WSGIScriptAlias / /home/my_linux_user/project2/django_project/wsgi.py

第一个虚拟主机做同样修改，去掉IfDefine包裹。

2. 重启Apache服务：执行sudo apachectl restart使配置生效。

额外检查项：

• 确认/home/my_linux_user/project2/django_project/wsgi.py文件权限，确保www-data用户有读取权限
• 验证project2虚拟环境路径正确性，python-home应指向包含bin/python的虚拟环境根目录
• 查看第二个域名的错误日志/var/log/apache2/error_project2.log，通过具体报错辅助排查潜在问题
