Django项目部署 - 主流部署方式 Django+mod_wsgi + Apache

Django+mod_wsgi + Apache环境是和比较小型的网站，也是Django的推荐环境

*启动MySQL

service [mariadb|mysqld] [start/restart]

*安装apache

！！！需要修改python到默认版本 2.7 参见http://blog.csdn.net/valexchao/article/details/51223120

yum install httpd httpd-devel -y

添加到自动启动

chkconfig httpd on

手动启动服务

service httpd start

浏览器输入localhost 可见apache页面

*重新编译python3

定位到python3解压后的文件夹中

make clean

重新编译 （因为缺少安装wsgi需要的共享库）

./configure --enable-shared

make

make install

添加共享库的位置到设置

vi /etc/ld.so.conf

再打开的文件增加 /usr/local/lib

:wq保存

执行下面的命令使之生效

/sbin/ldconfig -v

*下载mod_wsgi到downloads文件夹

wget https://pypi.python.org/packages/88/bd/3fa573dad32892f4fc24749bf008518439e9d7d23f539d75122d2f8d1479/mod_wsgi-4.5.2.tar.gz

tar zxvf mod_wsgi-4.5.2.tar.gz

cd mod_wsgi-4.5.2/

./configure

make 

make install

*修改一个文件

vi /etc/selinux/config

修改 

SELINUX=enforcing

为

SELINUX=disabled 

:wq保存

使之立刻生效

setenforce=0

*在项目的路径下增加一个配置文件

apache_django_wsgi.conf

内容如下

<del><del><IfModule mod_wgsi.c>WSGISocketPrefix /var/run/wsgiAlias /uploads/ /root/django-projects/prj1/uploads/Alias /static/ /root/django-projects/prj1/static/<Directory /root/django-projects/prj1/static>Require all granted</Directory><Directory /root/django-projects/prj1/uploads>Require all granted</Directory><Directory /root/django-projects/prj1/prj1><Files wsgi.py>Require all granted</Files></Directory>WSGIDaemonProcess blogprj1python-path=/root/django-projects/prj1:/usr/local/lib/python3.5/site-packages user=apachegroup=apacheWSGIProcessGroup blogprj1WSGIScriptAlias / /root/django-projects/prj1/prj1/wsgi.pyAddType text/html .py</IFModule></del></del>

*让apache读取上面的配置

vi /etc/httpd/conf/httpd.conf

在文件的最后添加下面两行

LoadModule wsgi_module modules/mod_wsgi.so
Include /root/django-projects/prj1/apache_django_wsgi.conf

在项目所在的文件下

chown -R apache:apache prj1

chmod -R 755 prj1

cd ..

chmod  755 django-projects

cd ..

chmod  755 root

重启

搞了好久搞不定

决定重新安装系统

centos6.5 

django1.8.3

python2.7.11

安装依赖包 必须先安装
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel python-devel mysql-devel gcc make  




下载python 2.7
wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
解压
tar zxvf Python-2.7.11.tgz
编译
./configure --enable-shared
make
make install
添加共享库的位置到设置
vi /etc/ld.so.conf
再打开的文件增加 /usr/local/lib
:wq保存
执行下面的命令使之生效
/sbin/ldconfig -v




安装mysql
yum install mysql-server
启动mysql
service mysqld start
登陆
mysql -uroot
创建一个数据库
CREATE DATABASE blog_db CHARSET=utf8
创建一个用户
GRANT ALL ON *.* TO valex@localhost IDENTIFIED BY "kylie";
修改root密码
SET PASSWORD FOR root@localhost=password('kylie');
FLUSH PRIVILEGES;




安装pip
先安装setuptools
wget https://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg  --no-check-certificate
chmod +x setuptools-0.6c11-py2.7.egg
sh setuptools-0.6c11-py2.7.egg
再安装pip
wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificate
tar zxvf pip-1.3.1.tar.gz
cd pip-1.3.1
python setup.py install






安装mysqlclient 连接mysql和django
pip install mysqlclient


安装Django 1.8.3
pip install django==1.8.3




<chmod -R  777  /home/mypackage
那么mypackage 文件夹和它下面的所有子文件夹的属性都变成了777.>
<安装vmware tools
下载VMwareTools-9.2.0-799703.tar.gz
进入解压后的文件夹 执行 
./vmware-install.pl
>


< 添加到启动项 ?
chkconfig mysqld on>


配置mysql到django


创建一个django project 叫mysite
修改settings.py中数据库设置
DATABASES = {  
    'default':{  
        'ENGINE':'django.db.backends.mysql',  
        'NAME':'blog_db',  
        'USER':'valex',  
        'PASSWORD':'kylie',  
    }  
}  


确保mysql服务已启动（需要管理员权限 su）
service mysqld start


定位到manage.py所在目录
$python manage.py migrate  
$python manage.py runserver 0.0.0.0:8080  


浏览器打开 localhost:8080
显示 It worked!  配置成功 


-------------------------------------


安装apache
yum install httpd httpd-devel -y
添加到自动启动
chkconfig httpd on
手动启动服务
service httpd start
浏览器输入localhost 可见apache页面


安装mod_wsgi <一定要这么安装 不能yum 或 pip>
下载mod_wsgi到downloads文件夹
wget https://pypi.python.org/packages/88/bd/3fa573dad32892f4fc24749bf008518439e9d7d23f539d75122d2f8d1479/mod_wsgi-4.5.2.tar.gz
tar zxvf mod_wsgi-4.5.2.tar.gz
cd mod_wsgi-4.5.2/
./configure
make 
make install




*修改一个文件
vi /etc/selinux/config
修改 
SELINUX=enforcing
为
SELINUX=disabled 
:wq保存
使之立刻生效
setenforce=0


配置apache和django 通过 wsgi


项目主目录下
新建文件apache_django_wsgi.conf

WSGIScriptAlias / /home/valex/mysite/mysite/wsgi.pyWSGIPythonPath /home/valex/mysite:/usr/local/lib/python2.7/site-packages<Directory /home/valex/mysite/mysite><Files wsgi.py>Require all granted</Files></Directory>

非windows下建议使用daemon mode

WSGISocketPrefix /var/run/wsgi WSGIScriptAlias / /home/valex/mysite/mysite/wsgi.py#WSGIPythonPath /home/valex/mysite:/usr/local/lib/python2.7/site-packages<Directory /home/valex/mysite/mysite><Files wsgi.py>Order deny,allowAllow from all#Require all granted</Files></Directory>WSGIDaemonProcess example.com python-path=/home/valex/mysite:/usr/local/lib/python2.7/site-packagesWSGIProcessGroup example.comWSGIScriptAlias / /home/valex/mysite/mysite/wsgi.py process-group=example.com

让apache读取上面的配置
vi /etc/httpd/conf/httpd.conf
在文件的最后添加下面两行
LoadModule wsgi_module modules/mod_wsgi.so
Include /home/valex/mysite/apache_django_wsgi.conf
在项目所在的文件下
chown -R apache:apache mysite
chmod -R 755 mysite
cd ..
chmod  755 mysite
...
cd ..
chmod  755 root
reboot
重启


打开浏览器 如果显示 Internal Server Error
查看apache错误日志
cat /var/log/httpd/error_log

基本上已经ok了

下一步是配置静态文件

修改apache_django_wsgi.conf

增加静态文件部分

WSGISocketPrefix /var/run/wsgi WSGIScriptAlias / /home/valex/mysite/mysite/wsgi.py#WSGIPythonPath /home/valex/mysite:/usr/local/lib/python2.7/site-packagesAlias /static/ /home/valex/mysite/static/<Directory /home/valex/mysite/static>Order deny,allowAllow from all</Directory><Directory /home/valex/mysite/mysite><Files wsgi.py>Order deny,allowAllow from all#Require all granted</Files></Directory>WSGIDaemonProcess example.com python-path=/home/valex/mysite:/usr/local/lib/python2.7/site-packagesWSGIProcessGroup example.comWSGIScriptAlias / /home/valex/mysite/mysite/wsgi.py process-group=example.com

settings.py中增加

STATIC_ROOT = os.path.join(BASE_DIR, "static")

python manage.py collectstatic

之后

localhost  localhost/admin的静态文件就都显示了
