Question

我得到这个错误：

 sudo service apache2 restart :


    [Thu Apr 18 13:11:02.687353 2019] [mpm_event:notice] [pid 2135:tid 140232732096384] AH00491: caught SIGTERM, shutting down

然后我进入我们站点的域并进入/var/log/apache2/error.log：

我正在使用AWS EC2上的ubuntu 16.0.4 apache2和nod_wsgi，开始启动正在运行的项目（不是新项目）

在我的wsgi.py中打印异常：

No module named boto from 

try:
  application = get_wsgi_application()
except Exception as e:
    print "err : {}".format(e)

但我必须安装boto：

# pip freeze | grep boto
You are using pip version 8.1.1, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
boto==2.49.0
boto3==1.9.112
botocore==1.12.16

这是我根据https://docs.djangoproject.com/en/2.2/topics/install/配置的其他文件：＃cat /etc/apache2/mods-enabled/wsgi.load LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

# cat /etc/apache2/mods-enabled/wsgi.conf
<IfModule mod_wsgi.c>


WSGIPassAuthorization on

WSGIScriptAlias / /home/ubuntu/path/to/wsgi.py
WSGIPythonPath  /home/ubuntu/path/to/my_project

<VirtualHost *:80>
        <Directory "/home/ubuntu/path/to//my_project/">
                Require all granted
        </Directory>
</VirtualHost>

 ..

</IfModule>

似乎您的site-packages指令中可能缺少WSGIPythonPath目录。我通常将python路径定义为WSGIDaemonProcess指令的一部分：

WSGIDaemonProcess example \
    display-name=example \
    processes=2 threads=20 \
    maximum-requests=10000 \
    umask=0002 \
    python-path=${SRV}/www:${SRV}/src:${SRV}/venv/prod_142/lib/python2.7/site-packages \
    python-eggs=${SRV}/.python-eggs

WSGIScriptAlias / ${SRV}/www/example/wsgi.py  \
    process-group=example      \
    application-group=%{GLOBAL}

您可以在https://github.com/datakortet/dkbuild-apacheconf的自述文件中看到功能更全的虚拟主机定义（我是作者）。

Answer 2

问题在于，并非所有python软件包都已安装，在安装了所有缺少的软件包后，网站可以正常工作

带有apache的wsgi无法读取通过管道安装的python软件包
