httpd mod_wsgi python3 pyramid 服务暂时不可用

httpd mod_wsgi python3 pyramid Service Temporary unavaliabe

很快我做了什么:

  1. 我下载了 python 3.5 源代码,使用
  2. 提取并编译了它们

`

./configure --enable-shared --prefix=/usr/local/lib
make&&make install

Then python couldn't find a libpython3.5m.so.1.0 so i've ran

export LD_LIBRARY_PATH=/usr/local/lib    
  1. 我使用 pip3.5 install mod_wsgi 安装了 mod_wsgi。

    我还尝试使用

    从源代码(从这里http://modwsgi.googlecode.com/files/mod_wsgi-3.4.tar.gz)安装它

    ./configure --with-python=/usr/local/bin/python3.5 make make install

    但是就这样结束了

`

/usr/lib64/apr-1/build/libtool --silent --mode=link gcc -o mod_wsgi.la  -rpath /usr/lib64/httpd/modules -module -avoid-version    mod_wsgi.lo -L/usr/local/lib -L/usr/local/lib/python3.5/config -lpython3.5 -lpthread -ldl -lutil -lrt -lm
/usr/bin/ld: cannot find -lpython3.5
collect2: ld returned 1 exit status
apxs:Error: Command failed with rc=65536
...

所以我继续使用 modwsgi 形式的 pip 但 lld 说它仍然是第 2 python 所以在里面

`

(env) [root@spiralarms mod_wsgi-3.4]# ldd /usr/lib64/httpd/modules/mod_wsgi.so 
    linux-vdso.so.1 =>  (0x00007fffc3fae000)
    libpython2.6.so.1.0 => /usr/lib64/libpython2.6.so.1.0 (0x00007fa1ea4c4000)
  1. 我在 /srv/modwsgi/env 中创建了 virtualenv 并安装了 pyramid

    使用 pcreate -s starter myapp、激活的 venv、运行 python setup.py install 创建了一个启动脚手架,并创建了 guestbook.wsgi 脚本

from pyramid.paster import get_app, setup_logging ini_path = '/srv/env/bin/myapp/production.ini' setup_logging(ini_path) application = get_app(ini_path, 'main')

然后我将整个 env 目录更改为 apache:apache

  1. 在 /etc/httpd/conf.d/ 中我创建了 guestbook.conf

`

WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess guestbook user=apache group=apache threads=4 \
   python-path=/srv/modwsgi/env/lib/python3.5/site-packages
WSGIPythonHome /srv/modwsgi/env/lib/python3.5/
WSGIScriptAlias /guestbook /srv/modwsgi/env/guestbook.wsgi

<Directory /srv/modwsgi/env>
  WSGIProcessGroup guestbook
  Order allow,deny
  Allow from all
</Directory>

最后我在浏览器中 运行 它显示

服务暂时不可用

由于维护停机或容量问题,服务器暂时无法为您的请求提供服务。请稍后再试。 Apache/2.2.15 (CentOS) 服务器位于 spiralarms.org 端口 80

当我尝试访问此页面时,错误日志中没有任何新内容

更新:

我尝试了 运行 一个简单的 wsgi 应用程序

import sys



def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'+str(sys.version_info)

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

似乎 mod_wsgi 使用 python 2,但它应该使用 3。

更新: 我终于编译并安装了 modwsgi(按照这个 https://github.com/GrahamDumpleton/mod_wsgi/issues/101(见最后 post)),现在它在导入编码模块时遇到问题

更新: 没有 WSGIPythonHome 它不会抱怨 encodings 但现在它给出 'internal server error'

更新: 终于找到了具有奇怪名称 'dummy host' 的日志,错误是我的配置中没有这一行 WSGISocketPrefix /var/run/wsgi

终于成功了!

调用日志文件(默认) dummy-host.example.com-error_log 并且位于 apache 日志目录

这是我的配置(为简单起见,它们在设计时没有使用 VirtualHosts)

guestbook.conf金字塔应用

LoadModule wsgi_module modules/mod_wsgi.so

WSGISocketPrefix /var/run/wsgi #don't forget this line

WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On

WSGIDaemonProcess guestbook user=apache group=apache threads=4 \
   python-path=/srv/modwsgi/env/lib/python3.5/site-packages
   #python-path=/usr/local/lib/python3.5/site-packages

WSGIScriptAlias /guestbook /srv/modwsgi/env/guestbook.wsgi

<Directory /srv/modwsgi/env>
  WSGIProcessGroup guestbook
  Order allow,deny
  Allow from all
</Directory>

这里是guestbook.wsgi

from pyramid.paster import get_app, setup_logging
ini_path = '/srv/modwsgi/env/guestbook-0.0/production.ini' #use a full path cause it will be runned from apache directory
setup_logging(ini_path)
application = get_app(ini_path, 'main')

对于非金字塔应用程序(显示我们的 python 版本的 hello world 示例)

hellowsgi.conf:

#LoadModule wsgi_module modules/mod_wsgi.so uncomment this if it's not in other configs or better put it in the global config
WSGIScriptAlias /hello /srv/modwsgi/hello.wsgi

hello.wsgi:

import sys

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'+str(sys.version_info)

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [bytes(output,'utf-8')] # use bytes for python 3 wsgi

另外不要忘记为所有文件授予对 apache 的访问权限。

我已经写了 an article 关于这个(俄语)
