Django项目部署

注意事项：

1. 要确保项目的settings.py文件中的数据库配置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': ' netshop',
        'HOST':'192.168.93.128',
        'PORT':3306,
        'USER':'root',
        'PASSWORD':'123456',
        'OPTIONS':{
                    'init_command':"SET sql_mode='STRICT_TRANS_TABLES'",
                    'charset':'utf8'
                }
    }
}

ALLOWED_HOSTS = ['*']

2. 在项目settings.py文件中添加

#将所有的静态文件收集到指定的目录下
STATIC_ROOT = 'd://static'

3. 在终端中运行以下命令(将static文件收集到d://static目录下)

python manage.py collectstatic

4. 在centos6中安装redis

5. 在centos6中安装mysql

单进程运行

1. 实现步骤：

   1. 通过xftp将本机的项目源码拷贝到远程服务器相应目录下

   2. 通过xshell连接远程服务器
      安装虚拟环境模块

    pip install virtualenv
   

   3. 通过命令创建商城项目运行的虚拟环境

   virtualenv netshop-env --python=python2.7
   

   4. **环境（切换到虚拟环境中的bin目录下）

   source activate
   

   5. 在虚拟环境中安装项目所需的所有类库
      (可以对比本机上的settings进行安装)

   pip install django 
   

   6. 进入到商城项目目录下启动服务

   python manage.py runserver 0.0.0.0:9000
   

多进程运行

目的：supervisor为一个项目管理多个进程

1. 实现步骤

   1. 安装supervisor模块

   pip install supervisor
   

   2. 通过命令产生默认配置文件

   echo_supervisord_conf > supervisord.conf 
   

   3. 修改supervisord.conf配置文件

           ；[include]
   		；files = relative/directory/*.ini	
   		修改为
   		[include]
   		files = /etc/supervisor/*.conf
   		
   

   4. 将当前配置文件拷贝到/etc/目录下

   cp supervisord.conf /etc/
   

   5. 在/etc/目录下创建/supervisor/django.conf文件
      django.conf的内容为：

[group:djangos]
programs=django-8000,django-8001,django-8002,django-8003

[program:django-8000]
command=/home/laozhang/codes/netshop/bin/python2.7 /home/laozhang/codes/netshop/manage.py runserver 0.0.0.0:8000
directory=/home/laozhang/codes/netshop
user=laozhang
autorestart=true
redirect_stderr=true
stdout_logfile=/home/laozhang/codes/netshop/django.log
loglevel=info

[program:django-8001]
command=/home/laozhang/codes/netshop/bin/python2.7 /home/laozhang/codes/netshop/manage.py runserver 0.0.0.0:8001
directory=/home/laozhang/codes/netshop
user=laozhang
autorestart=true
redirect_stderr=true
stdout_logfile=/home/laozhang/codes/netstore/django.log
loglevel=info


[program:django-8002]
command=/home/laozhang/codes/netshop/bin/python2.7 /home/laozhang/codes/netstore/manage.py runserver 0.0.0.0:8002
directory=/home/laozhang/codes/netstore
user=laozhang
autorestart=true
redirect_stderr=true
stdout_logfile=/home/laozhang/codes/netstore/django.log
loglevel=info


[program:django-8003]
command=/home/laozhang/codes/netshop/bin/python2.7 /home/laozhang/codes/netstore/manage.py runserver 0.0.0.0:8003
directory=/home/laozhang/codes/netstore
user=laozhang
autorestart=true
redirect_stderr=true
stdout_logfile=/home/laozhang/codes/netshop/django.log
loglevel=info

6. 启动/查看进程

            #启动进程
            supervisord -c /etc/supervisord.conf
            
            #查看进程
			ps aux | grep supervisord #查看进程是否存在
			
			#杀死进程
			kill 杀死进程pid

7. 客户端使用

            supervisorctl  #客户端命令

			status    # 查看程序状态
			stop djangos:*   # 关闭 djangos组 程序
		    start djangos:*  # 启动 djangos组 程序
			restart djangos:*    # 重启 djangos组 程序
			update    ＃ 重启配置文件修改过的程序

8. 在主机访问不同端口下的项目即可

ngnix多进程

1. nginx的安装http://www.runoob.com/linux/nginx-install-setup.html

2. 编辑/usr/local/webserver/nginx/conf/nginx.conf文件

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}
http
{
  include mime.types;
  default_type application/octet-stream;


  # log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
  #             '$status $body_bytes_sent "$http_referer" '
  #             '"$http_user_agent" $http_x_forwarded_for';
  
#charset gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;
     
  sendfile on;
  #tcp_nopush on;
  keepalive_timeout 60;
  #gzip on;

  upstream djangos{
  server 0.0.0.0:8000;
  server 0.0.0.0:8001;
  server 0.0.0.0:8002;
  server 0.0.0.0:8003;
	
  }


 
 
  #limit_zone crawler $binary_remote_addr 10m;
 #下面是server虚拟主机的配置
 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    
    location / {
    proxy_pass_header Server;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Scheme $scheme;
    proxy_pass http://djangos;
    }
    location /static {
    autoindex on;
    alias /var/www/static/;
    }
    location /media {
    autoindex on;
    alias /var/www/media/;
    }
	

   # access_log off;

     error_page 500 502 503 504 /50x.html;
     location = /50x.html{
         root html;
     }



    }

}

3. 通过xftp将项目中的静态文件拷贝到www用户下

4.启动nginx服务访问页面内容

5.确定redis服务是否启动

/usr/local/redis/bin/各种命令
/usr/local/redis/etc/redis.conf配置文件

#启动redis服务
redis-server etc/redis.conf
