环境准备与依赖安装

执行以下命令安装Apache与开发工具包：

sudo yum install httpd httpd-devel
sudo yum groupinstall "Development Tools"

安装Python开发库（以Python 3为例）：

sudo yum install python3-devel

安装mod_wsgi模块

通过pip安装并关联Apache：

sudo pip3 install mod_wsgi
sudo mod_wsgi-express install-module

验证模块加载状态：

httpd -M | grep wsgi

Apache虚拟主机配置

创建配置文件/etc/httpd/conf.d/wsgi.conf：

<VirtualHost *:80>
    ServerName yourdomain.com
    WSGIDaemonProcess myapp python-path=/var/www/myapp:/usr/lib/python3.6/site-packages
    WSGIProcessGroup myapp
    WSGIScriptAlias / /var/www/myapp/app.wsgi

    <Directory /var/www/myapp>
        Require all granted
    </Directory>
</VirtualHost>

应用测试与权限设置

创建测试WSGI脚本app.wsgi：

def application(environ, start_response):
    status = '200 OK'
    output = b'Hello World!'
    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)
    return [output]

设置目录权限并重启服务：

sudo chown -R apache:apache /var/www/myapp
sudo systemctl restart httpd

故障排查与优化

• 检查Apache错误日志：tail -f /var/log/httpd/error_log
• 确认SELinux策略：setsebool -P httpd_enable_homedirs 1
• 验证防火墙设置：sudo firewall-cmd --permanent --add-service=http
