Django项目部署

将Django项目部署在LAMP/LNMP平台上,用于真正的生产环境,需要注意一下两点:

数据库编码

1. 数据库创建
CREATE DATABASE `test` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
2. 数据库设置 /etc/my.cnf
[client]
default-character-set=utf8
[mysqld]
character-set-server= utf8
default-character-set= utf8
init_connect='SET NAMES utf8'
[mysql]
default-character-set=utf8
# mysql 查看数据库信息如下
mysql > use test
mysql > status
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
3. 项目设置 djangoproject/setting.py设置如下
TIME_ZONE = 'Asia/Shanghai'
LANGUAGE_CODE = 'zh-cn'
DEFAULT_CHARSET = 'utf-8'
TEST_CHARSET = 'utf-8'
TEST_COLLATION = 'utf-8'
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'test2',
'USER': 'root',
'PASSWORD': '',
'HOST': '172.16.20.64',
'PORT': '3306',
'TEST_CHARSET': 'utf-8',
'TEST_COLLATION': 'utf-8',
'DEFAULT_CHARSET': 'utf-8',
}
}

2. UWSGI反代
项目中使用到了Django,MySQLdb,当然还有apache反代django时需要的uWSGI
还有两个依赖库 python-devel以及mysql-devel

1. 安装依赖库
yum -y install python-devel mysql-devel

2. 安装apache uWSGI模块(如果使用nginx这步可以省略)
wget --no-check-certificate # 编译uWSGI.c文件
/apache安装目录/bin/apxs -i -c mod_uwsgi.c

3. 配置httpd.conf
# 这些东西加在那里浏览一遍conf文件你就知道 :)
LoadModule uwsgi_module modules/mod_uwsgi.so

<Location "/">
SetHandler uwsgi-handler
uWSGISocket 127.0.0.1:8080  # 这是指定反代地址
</Location>

<Location "/static">
SetHandler none  # 这是定义django静态文件处理方式
</Location>
# 静态文件alias
Alias /static /data01/httpd/htdocs/thirddjango/static

4. 在htdocs目录下设置UWSGI.INI
[uwsgi]
chdir = /data01/httpd/htdocs/thirddjango   # httpd的发布目录
module = thirddjango.wsgi   # django项目中的wsgi
env DJANGO_SETTINGS_MODULE=thirddjango.settings  # 项目settings文件

master = true
processes = 2
socket = 127.0.0.1:8080   # uwsgi工作端口
max-requests = 100
vacuum = true
daemonize = /data01/httpd/logs/django.log  # django日志文件位置

5. 安装Django,MySQLdb模块
# 安装easy_install工具,便于安装以上的模块
wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py python ez_setup.py install

easy_install django
easy_install "MySQL-python==1.2.3"
