如果有钱,这件事就没有必要。             

腾讯云ubuntu,采用22.04LTS版本,自带Python 3.10.12 

Welcome to Ubuntu 22.04 LTS (GNU/Linux 5.15.0-86-generic x86_64)

没有提供root,考虑到ubuntu的不熟练,按常见问题的解决,添加root按密码登陆,避免了权限修改问题。

1.安装Nginx

root@VM-8-13-ubuntu:/home/ubuntu/hnuliulinhai/blogproject# nginx -v
nginx version: nginx/1.18.0 (Ubuntu)

Nginx 的配置文件分两块,主体位于 /etc/nginx/nginx.conf 文件中,该设置文件开头采用user root,该设置默认为www-data,需要修改,否则导致静态文件不能加载,响应403拒绝访问,此事浪费较长时间调试。

主体文件中通过include /etc/nginx/conf.d/*.conf;语句将我们的另一位于/etc/nginx/conf.d目录下的server配置文件mysite_nginx.conf加载。

nginx重启不在赘述

2.使用pipenv

pip3 install pipenv
cd /home/ubuntu/hnuliulinhai/blogproject
pipenv install django==4.0
pipenv install django-contrib-comments
pipenv install django-qiniu-strorage
pipenv install django-ckeditor
pipenv install gunicorn
pipenv install django-utils-six
pipenv install Pillow

在项目文件夹下,使用pipenv install安装,可以自动生成环境。所有包装好后,pipenv graph后的结果:

root@VM-8-13-ubuntu:/home/ubuntu/hnuliulinhai/blogproject# pipenv graph

pipenv shell可以进入环境,可以省略输入pipenv run。

cd /home/ubuntu/hnuliulinhai/blogproject
pipenv shell
python manage.py makemigrations
python manage.py migrate
python manage.py runserver

3.使用gunicorn

在Nginx的server配置文件中,除了一些静态文件由Nginx直接处理外,其他传给代理gunicorn处理,即:

    location / {
	    proxy_set_header Host $host;
		proxy_pass http://127.0.0.1:8000;
        #uwsgi_pass  django;
        #include     /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
    }

在项目文件下,运行gunicorn的方式:

cd /home/ubuntu/hnuliulinhai/blogproject

 pipenv run gunicorn blogproject.wsgi -w 2 -k gthread -b 127.0.0.1:8000

从上可知,127.0.0.1:8000与Nginx里的配置有对应关系。

4.使用supervisor

采用如下目录结构管理相关文件,同时对配置文件的目录进行相应修改。

其中 supervisord.conf 是 Supervior 的配置文件,它会通过include包含 conf.d 下的配置。var 目录下用于存放一些经常变动的文件,例如 socket 文件,pid 文件,log 下则存放日志文件。

~/etc

├── supervisor
│   ├── conf.d
│   └── var
│       ├── log
└── supervisord.conf

首先建立目录结构:

mkdir -p ~/etc/supervisor/conf.d
mkdir -p ~/etc/supervisor/var/log

相应的文件,如果网站目录结构没有发生变化,可以直接使用,不再赘述,摘录见后。

其常见用法为查看状态和重启,最好先到配置文件目录,cd /root/etc


root@VM-8-13-ubuntu:~# sudo supervisorctl status
blogproject                      RUNNING   pid 740426, uptime 2 days, 17:46:44

root@VM-8-13-ubuntu:~#

supervisord.conf文件:

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
;
; Warning:
;  Paths throughout this example file use /tmp because it is available on most
;  systems.  You will likely need to change these to locations more appropriate
;  for your system.  Some systems periodically delete older files in /tmp.
;  Notably, if the socket file defined in the [unix_http_server] section below
;  is deleted, supervisorctl will be unable to connect to supervisord.

[unix_http_server]

; Security Warning:
;  The inet HTTP server is not enabled by default.  The inet HTTP server is
;  enabled by uncommenting the [inet_http_server] section below.  The inet
;  HTTP server is intended for use within a trusted environment only.  It
;  should only be bound to localhost or only accessible from within an
;  isolated, trusted network.  The inet HTTP server does not support any
;  form of encryption.  The inet HTTP server does not use authentication
;  by default (see the username= and password= options to add authentication).
;  Never expose the inet HTTP server to the public internet.

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include]
files =  /root/etc/supervisor/conf.d/*.ini

conf.d/blogproject.ini文件

[program:blogproject]
command=pipenv run gunicorn blogproject.wsgi -w 2 -k gthread -b 127.0.0.1:8000
directory=/home/ubuntu/hnuliulinhai/blogproject
autostart=true
autorestart=unexpected
user=root
stdout_logfile=/root/etc/supervisor/var/log/blogproject.log
stderr_logfile=/root/etc/supervisor/var/log/blogproject.log

这里面autostart是使用supervisor的主要原因。

5.升级Django4.0

由于使用了python3.10版本,将Django从2.2升级到了4.0,主要修改有

settings.py添加如下配置:

DEFAULT_AUTO_FIELD='django.db.models.AutoField'
SECURE_CROSS_ORIGIN_OPENER_POLICY = 'None'
#2023.10.27

urls.py修改引用包django.urls,方法url改用re_path:

#from django.conf.urls import url,include
from django.urls import re_path,include
from django.contrib import admin
#from DjangoUeditor import urls as DjangoUeditor_urls
from blog.feeds import AllPostsRssFeed

urlpatterns = [
    re_path(r'^admin/', admin.site.urls),
    #url(r'',include('blog.urls')),
    re_path(r'',include('blog.urls')),
    #url(r'^ueditor/',include('DjangoUeditor.urls' )),
    re_path(r'^comments/', include('django_comments.urls')),
    re_path(r'^all/rss/$', AllPostsRssFeed(), name='rss'),
    re_path(r'^ckeditor/', include('ckeditor_uploader.urls')),
]

blog里的urls.py亦相同调整。

模板文件detail2.html使用模板标签if替换ifequal。

6. 其他

将域名解析调整,已经无缝衔接到原有文章的访问,并此文为计。
