apache2错误日志.呼叫'(null)'的'site.addsitedir()'失败，停止 [英] apache2 error log. Call to 'site.addsitedir()' failed for '(null)', stopping
问题描述
我想在Ubuntu中连接Python和Apache 2服务器.
因此aws必须输入以下代码ubuntu服务器.
pip install Django
sudo apt-get install appache2
sudo apt-get install libapache2-mod-wsgi-py3
然后我将Python项目和app文件夹创建为Python venv.
Apache 2 000-default.conf的代码如下:
<virtualhost *:80>
WSGIDaemonProcess bot python-path=/home/ubuntu/Django/bot:/home/ubuntu/Django/myvenv/lib/python3.5/site-packages
ServerAdmin webmaster@localhost
WSGIScriptAlias /52.78.108.223 /home/ubuntu/Django/bot/wsgi.py
<Directory /home/ubuntu/Django/bot>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</virtualhost>
位置正确.没有输入错误.
'WSGIScriptAlias/'的第一个参数应该为空白，但是如果将其放在空白处，则当您点击该IP时将看不到'it walk'页面.所以我把服务器的外部IP.然后它走的很好.
查看Apache 2错误日志.

它像这样出来.
我搜索了互联网.据说wsgi版本低.
但是，apache2使用的wsgi只能与'sudo apt-get install libapache2-mod-wsgi-py3'一起安装.
Apache 2错误日志显示wsgi版本为4.3.0.
如果使用"pip install mod-wsgi"安装最新版本的wsgi，则Apache 2错误日志将显示4.3.0.
'呼叫'site.addsitedir()'失败'(null)'，停止.错误日志仍会出现.
如何解决此错误?
请勿使用mod_wsgi 4.3.0.它非常旧，并且存在内存问题，无法为python-path提供多个目录.或者使用:
WSGIDaemonProcess bot python-home=/home/ubuntu/Django/myvenv python-path=/home/ubuntu/Django/bot
您不应将site-packages与python-path一起使用.这不是推荐的方法，自mod_wsgi 3.3起就没有.
有关使用虚拟环境的更多详细信息，请参见:
如果使用pip install mod_wsgi后没有显示最新的mod_wsgi，那是因为您没有禁用/卸载系统mod_wsgi软件包.您可能需要通过运行mod_wsgi-express module-config并获取输出并将其添加到Apache配置中，来手动配置Apache以加载较新的mod_wsgi.
I would like to connect Python and Apache 2 server in Ubuntu.
So aws have to enter the following code ubuntu server.
pip install Django
sudo apt-get install appache2
sudo apt-get install libapache2-mod-wsgi-py3
Then I created the Python project and the app folder as Python venv.
The code for Apache 2 000-default.conf looks like this:
<virtualhost *:80>
WSGIDaemonProcess bot python-path=/home/ubuntu/Django/bot:/home/ubuntu/Django/myvenv/lib/python3.5/site-packages
ServerAdmin webmaster@localhost
WSGIScriptAlias /52.78.108.223 /home/ubuntu/Django/bot/wsgi.py
<Directory /home/ubuntu/Django/bot>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</virtualhost>
The location is correct. There is no typing miss.
The first argument to 'WSGIScriptAlias /' should be blank, but if you put it in a blank space, you will not see the 'it walked' page when you hit that IP. So I put the external IP of the server. Then it walked well.
Looking at the Apache 2 error log.

It comes out like this.
I searched the internet. It is said that wsgi version is low.
However, wsgi used by apache2 can only be installed with 'sudo apt-get install libapache2-mod-wsgi-py3'.
The Apache 2 error log shows that wsgi version is 4.3.0.
If you install the latest version of wsgi with 'pip install mod-wsgi', the Apache 2 error log will show 4.3.0.
'Call to' site.addsitedir () 'failed for' (null) ', stopping.' The error log still appears.
How do I resolve this error?
Don't use mod_wsgi 4.3.0. It is very old and has an issue from memory with providing multiple directories to python-path. Alternatively use:
WSGIDaemonProcess bot python-home=/home/ubuntu/Django/myvenv python-path=/home/ubuntu/Django/bot
You shouldn't be using site-packages with python-path. That is not the recommended way and hasn't been since mod_wsgi 3.3.
For more details on using virtual environments, see:
If after using pip install mod_wsgi it doesn't show latest mod_wsgi, it is because you didn't disable/uninstall the system mod_wsgi package. You would need to have manually configured Apache to load the newer mod_wsgi as well, by running mod_wsgi-express module-config and taking the output and add it to Apache configuration.
