Linux下配置Apache+Mod\_Wsgi+Django環境

一．安裝環境

操作系統：CentOS release 5.5

內核版本：Linux Svn-168-1-11 2.6.18-194.el5 \#1 SMP Fri Apr 2 14:58:14 EDT 2010 x86\_64 x86\_64 x86\_64 GNU/Linux

Python版本：Python 2.4.3

Apche版本：httpd-2.2.3

Mod\_Wsgi版本：mod\_wsgi-3.2-1.el5.x86\_64.rpm

Django版本：Django-1.2.4

二．軟件安裝

Python采用默認rpm安裝路徑

安裝Apache：

yum –y install httpd(httpd-2.2.3-53.el5.centos.1.x86\_64.rpm)

安裝Mod\_Wsgi：

rpm –ivh mod\_wsgi-3.2-1.el5.x86\_64.rpm

安裝Django：

tar –zxvf Django-1.2.4.tar.gz

cd Django-1.2.4

python setup.py install

安裝MySQLdb

wget -q http://peak.telecommunity.com/dist/ez\_setup.py

python ez\_setup.py

tar –zxvf MySQL-python-1.2.3.tar.gz

cd  MySQL-python-1.2.3

python setup.py build

python setup.py install

安裝成功驗證：

Shell>python

Python 2.4.3 (\#1, May  5 2011, 16:39:10)

\[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)\] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import django

>>> django.VERSION

(1, 2, 4, 'final', 0)

>>> import MySQLdb

>>>

shell>ls /etc/httpd/conf.d

proxy\_ajp.conf  README  welcome.conf wsgi.conf

mod\_wsgi.so

三．項目部署

1.打包壓縮開發代碼:dajie.zip

2.上傳至服務器並解壓縮至目錄/var/www/html

Shell> ls /var/www/html/

dajie

3.修改Apche配置文件httpd.conf

Shell> vi /etc/httpd/conf/httpd.conf

\#\#\#在最后添加如下內容

ServerName mice.operation.dajie-inc.com

DocumentRoot /var/www/html/dajie

WSGIScriptAlias / /var/www/html/dajie/apache/django.wsgi

Order deny,allow

Allow from all

4.創建並配置wsgi的配置文件：

Shell>cd /var/www/html/dajie

Shell>mkdir apache

Shell>touch django.wsgi

Shell>cat django.wsgi

import os, sys

\#Calculate the path based on the location of the WSGI script.

apache\_configuration= os.path.dirname(\_\_file\_\_)

project = os.path.dirname(apache\_configuration)

workspace = os.path.dirname(project)

sys.path.append(workspace)

os.environ\['DJANGO\_SETTINGS\_MODULE'\] = 'dajie.settings'

os.environ\['PYTHON\_EGG\_CACHE'\] = '/tmp'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

print >> sys.stderr, sys.path

shell>chmod a+x django.wsgi

5.修改django項目的配置文件/var/www/html/dajie/settings.py,主要是下面兩處：

DATABASES = \{

'default': \{

'ENGINE': 'django.db.backends.mysql',

'NAME': 'dajieod',

'USER': 'dajieod',

'PASSWORD': 'dajieod123',

'HOST': '127.0.0.1',

'PORT': '3306',                         \}

TEMPLATE\_DIRS = (

\# Put strings here, like "/home/html/django\_templates" or "C:/www/django/templates".

\# Always use forward slashes, even on Windows.

\# Don't forget to use absolute paths, not relative paths.

'/var/www/html/dajie/templates',

)

四．啟動項目

shell>service httpd restart

訪問測試：

項目部署ok~

五．問題集

1.安裝MySQL-python執行：python setup.py build報錯：EnvironmentError: mysql\_config not found

方法解決：ln -s /usr/local/mysql/bin/mysql\_config /usr/local/bin/mysql\_config將mysql\_confi從你的安裝目錄鏈接到/usr/local/bin目錄下，這樣就可以在任意目錄下訪問了(也可以放到/usr/bin)

2. import MySQLdb報錯：ImportError: libmysqlclient\_r.so.16: cannot open shared object file: No such file or directory

解決方法：將mysql/lib下所有關於libmysqlclient的so文件軟鏈接到/usr/lib下。

ln -s /usr/local/mysql/lib/mysql/libmysqlclient\* /usr/lib

ldconfig這樣import MySQLdb的時候就不會出錯了

3.在系統環境中安裝完django、MySQLdb后，執行import都沒有問題，但是啟動Apache后，瀏覽器訪問時卻報錯：

Error loading MySQLdb module: ImportError: libmysqlclient\_r.so.16: cannot open shared object file: Permission denied

解決方法：這里apache的Permission denied問題是由SELINUX引起的，關閉SELINUX即可。關閉Selinux：vi /etc/selinux/config===》SELINUX=disabled，然后重啟系統

(不重啟設置Selinux:setenforce 0查看Selinux:getenforce)
