❯ sudo cp /var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so /etc/httpd/modules/mod_wsgi_python3.so
这里用3.6版本的覆盖了3.12版本的so，当然标准的程序是不能这么做的。应该自己配置好哪个so文件会被优先访问。毕竟在/etc/httpd/conf.d/wsgi.conf 中写明了：
LoadModule wsgi_module "/var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
WSGIPythonHome "/var/www/Treemap/venv" 请问应该如何配置好httpd哪个so文件会被优先访问？
● 问题在于 Fedora 系统的 mod_wsgi 包也会装一个加载配置。两个 LoadModule 冲突时，先加载的那个生效。
排查
先看系统有没有自带的 mod_wsgi 加载配置：
ls /etc/httpd/conf.modules.d/*wsgi*
通常会有个 10-wsgi.conf，内容类似：
LoadModule wsgi_module modules/mod_wsgi_python3.so
这个文件会在你的 conf.d/wsgi.conf 之前加载（conf.modules.d 优先于 conf.d）。
解决方法
禁用系统自带的 mod_wsgi，只保留你的：
# 1. 把系统自带的 mod_wsgi 配置禁用（不要删，改后缀即可）
sudo mv /etc/httpd/conf.modules.d/10-wsgi.conf /etc/httpd/conf.modules.d/10-wsgi.conf.bak
# 2. 确认你的 /etc/httpd/conf.d/wsgi.conf 内容正确
# LoadModule 指向 venv 里的 .so，WSGIPythonHome 指向 venv
你的 /etc/httpd/conf.d/wsgi.conf 保持：
LoadModule wsgi_module "/var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
WSGIPythonHome "/var/www/Treemap/venv"
# 3. 如果之前覆盖了系统 .so，还原回去
sudo dnf reinstall mod_wsgi # 恢复原始的 3.12 版 .so 文件
# 4. 验证配置无误后重启
sudo apachectl configtest
sudo systemctl restart httpd
加载顺序说明
httpd 按字母序加载配置：
1. conf.modules.d/ — 模块加载（10-wsgi.conf 等）
2. conf.d/ — 应用配置（你的 wsgi.conf）
LoadModule 对同一个模块名只能出现一次，第二次会报错 module wsgi_module is already loaded。所以必须禁用其中一个，不存在"优先级"的概念——只能加载一个。
❯ 按你的改了.sudo systemctl restart httpd 报错：The job identifier is 9182.

● failed to map segment from shared object — 这是 SELinux 阻止 httpd 加载 venv 目录下的 .so 文件。
修复：
# 给 venv 下的 mod_wsgi .so 文件设置正确的 SELinux 上下文
sudo semanage fcontext -a -t httpd_modules_t "/var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/.*\.so"
sudo restorecon -v /var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so
# 验证上下文已生效
ls -Z /var/www/Treemap/venv/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so
应该看到类型变成 httpd_modules_t。然后：
sudo apachectl configtest
sudo systemctl restart httpd
如果 semanage 命令不存在，先安装：
sudo dnf install policycoreutils-python-utils
——如果selinux仍有问题，对之最好的方法是停用selinux。
- sudo sed -i 's/^SELINUX=enforcing/SELINUX=disable/' /etc/selinux/config
或SELINUX=permissive 只记录，不阻止。
