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-release
yum 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/sams
python 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==2.2.1
Collecting Django==2.2.1
Using cached https://files.pythonhosted.org/packages/b1/1d/2476110614367adfb079a9bc718621f9fc8351e9214e1750cae1832d4090/Django-2.2.1-py3-none-any.whl

Uninstalling Django-2.2:

[root@sm-manage220 sams]# pip list
Package 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.wsgi
master = true
processes = 3
socket = 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 = true
pidfile = /data/sams/script/uwsgi.pid
daemonize = /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 uwsgi
root 14200 1 0 19:01 ? 00:00:00 uwsgi --ini uwsgi.ini
root 14202 14200 0 19:01 ? 00:00:00 uwsgi --ini uwsgi.ini
root 14203 14200 0 19:01 ? 00:00:00 uwsgi --ini uwsgi.ini
root 14204 14200 0 19:01 ? 00:00:00 uwsgi --ini uwsgi.ini
root 14205 14200 0 19:01 ? 00:00:00 uwsgi --ini uwsgi.ini
root 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 uwsgi
root 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/sams
module = sams.wsgi
master = true
processes = 3
socket = 0.0.0.0:8001
#http = 0.0.0.0:8000
vacuum = true
pidfile = /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/sams
mkdir static
vim /data/sams/sams/settings.py
在最后增加一行
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
然后 cd /data/sams
python 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 nginx
Created 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

After=network.target

ExecReload=/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.
