这篇文章主要介绍"django搭建一个资产管理系统"，在日常操作中，相信很多人在django搭建一个资产管理系统问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"django搭建一个资产管理系统"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

Centos7.4 yum安装python3.6

然后安装mysql(mariadb)

yum install -y mariadb mariadb-libs mariadb-devel mariadb-server

nginx

yum install epel-releaseyum install -y nginx

再安装django2.2.0

pip install django==2.2.0

-------------------------------------更新于2019.10.24--------------------------------------------

首先修改settings

把

ALLOWED_HOSTS = []修改为ALLOWED_HOSTS = ['*',]           即允许所有主机访问

把刚做好IP管理的项目整个文件夹放在服务器上,此处我选择的放在/data下

尝试执行用django自带的web服务器开启服务

cd /data/samspython manage.py run server 0:8000

发现有报错

RuntimeError: Model class login.models.User doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

然而百度了一圈我还是解决不了所以我决定升级django版本

[root@sm-manage220 sams]# pip install Django==2.2.1Collecting Django==2.2.1  Using cached https://files.pythonhosted.org/packages/b1/1d/2476110614367adfb079a9bc718621f9fc8351e9214e1750cae1832d4090/Django-2.2.1-py3-none-any.whlRequirement already satisfied: pytz in /usr/lib/python3.6/site-packages (from Django==2.2.1) (2019.2)Requirement already satisfied: sqlparse in /usr/lib/python3.6/site-packages (from Django==2.2.1) (0.3.0)Installing collected packages: Django  Found existing installation: Django 2.2    Uninstalling Django-2.2:      Successfully uninstalled Django-2.2Successfully installed Django-2.2.1[root@sm-manage220 sams]# pip listPackage     Version----------- -------Django      2.2.1  pip         19.3.1 PyMySQL     0.9.3  python-nmap 0.6.1  pytz        2019.2 setuptools  39.0.1 sqlparse    0.3.0  [root@sm-manage220 sams]#

然后在执行 python manage.py runserver,又特么报错了

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

这个解决就简单一点了

  File "/usr/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 36, in     raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

直接去注释掉这一行就是了

好的注释掉之后出现第二个异常了

 File "/usr/lib/python3.6/site-packages/django/db/backends/mysql/operations.py", line 146, in last_executed_query    query = query.decode(errors='replace')AttributeError: 'str' object has no attribute 'decode'

将146行的decode改为encode即可

if query is not None:    query = query.encode(errors='replace')return query

然后执行python manage.py runserver 0:8000就可以启动服务了(0:8000即允许所有机器都可以通过8000端口访问)

然后执行pip install uwsgi,还是报错

再安装gcc吧

yum install -y gcc

再执行 pip install uwsgi就可以了,然后开始配置它

在项目的根目录下新建一个script目录，新建一个uwsgi.ini文件。文件名可以随便，但后缀必须是ini。

在里面写入下面的配置内容：

[uwsgi]chdir           = /data/sams      #整个项目的路径module          = sams.wsgi       #项目的名称.wsgimaster          = trueprocesses       = 3socket          = 0.0.0.0:8001    #如果想用nginx再做反向代理的话就输入这个http            = 0.0.0.0:8000    #不用nginx做就输入这个,这个主要是测试当前配置的有没有问题vacuum          = truepidfile = /data/sams/script/uwsgi.piddaemonize  = /data/sams/script/uwsgi.log

注意直接复制会报错找不到项目路径,实际最好把注释的文字自行删除,包括空格

可以直接用8000端口访问了,接下来我们再配置nginx

然后我们把uwsgi停掉,注释掉http那一行,改用nginx做代理

[root@sm-manage220 nginx]# ps -ef |grep uwsgiroot     14200     1  0 19:01 ?        00:00:00 uwsgi --ini uwsgi.iniroot     14202 14200  0 19:01 ?        00:00:00 uwsgi --ini uwsgi.iniroot     14203 14200  0 19:01 ?        00:00:00 uwsgi --ini uwsgi.iniroot     14204 14200  0 19:01 ?        00:00:00 uwsgi --ini uwsgi.iniroot     14205 14200  0 19:01 ?        00:00:00 uwsgi --ini uwsgi.iniroot     14532 13144  0 19:16 pts/0    00:00:00 grep --color=auto uwsgi[root@sm-manage220 nginx]# pkill -f uwsgi -9[root@sm-manage220 nginx]# ps -ef |grep uwsgiroot     14543 13144  0 19:16 pts/0    00:00:00 grep --color=auto uwsgi[root@sm-manage220 nginx]# vim /data/sams/script/uwsgi.ini[uwsgi]chdir           = /data/samsmodule          = sams.wsgimaster          = trueprocesses       = 3socket          = 0.0.0.0:8001#http            = 0.0.0.0:8000vacuum          = truepidfile = /data/sams/script/uwsgi.pid#daemonize  = /data/sams/script/uwsgi.log #这种方式会以守护进程的方式存在,会导致后面设置systemctl的时候失败logto = /data/sams/script/uwsgi.log #推荐采取这样子的方式记录log

    server {            listen       80;            server_name  localhost;            access_log      /data/sams/script/sams_access.log;            error_log       /data/sams/script/sams_error.log;            client_max_body_size 75M;            location / {                include uwsgi_params;                uwsgi_pass 127.0.0.1:8001;                uwsgi_param UWSGI_SCRIPT sams.wsgi;                uwsgi_param UWSGI_CHDIR  /data/sams;        }        location /static {                alias /data/sams/static;        }    }

配置静态资源

cd /data/samsmkdir staticvim /data/sams/sams/settings.py在最后增加一行STATIC_ROOT = os.path.join(BASE_DIR, 'static')然后 cd /data/samspython manage.py collectstatic

然后启动nginx和uwsgi并设置服务的自启动

[root@sm-manage220 nginx]# systemctl restart nginx[root@sm-manage220 nginx]# cd /data/sams/script/[root@sm-manage220 script]# uwsgi --ini uwsgi.ini [uWSGI] getting INI configuration from uwsgi.ini[root@sm-manage220 ~]# systemctl enable nginxCreated symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.#设置uwsgi为服务,方便管理vim /usr/lib/systemd/system/uwsgi.service[Unit]Description=uWSGI instance to serve myprojectAfter=network.target[Service][Unit]Description=uWSGI instance to serve myprojectAfter=network.target[Service]WorkingDirectory=/data/samsExecStart=/usr/local/bin/uwsgi --ini /data/sams/script/uwsgi.iniExecStop=/usr/local/bin/uwsgi --stop /data/sams/script/uwsgi.pidExecReload=/usr/local/bin/uwsgi --reload /data/sams/script/uwsgi.pid[Install]WantedBy=multi-user.target#然后执行命令设置成开机自启动systemctl enable uwsgi

--------------------------------------------------分割线-------------------------------------------------------

ps: 这样子的方式即可使用systemctl start/stop/reload/enable/disable进行管理,我之前的方式开机启动uwsgi是把启动命令/usr/local/bin/uwsgi --ini /data/sams/script/uwsgi.ini写在rc.local里面,并且uwsgi.ini这个文件里我使用的是daemonize记录log而不是logto,这样子就导致在重启服务器时会卡在界面,一直提示a stop job is running for /etc/rc.d/rc.local,只能强制关机,再强制开机.

--------------------------------------------------分割线-------------------------------------------------------
