crm--纯后端部署
技术栈：supervisor + nginx + uwsgi + django + virtualenv + mariadb
基本流程
crm 纯后端部署是通过模板语言进行和前端通信的，前端代码写在后端中
<!--模板语言-->
{{static.el}}
先配置后端,uwsgi+crm进行项目运行

安装uwsgi
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple uwsgi线上部署时，uwsgi.ini需要修改添加如下参数，关闭http参数
(s25_crm) [root@localhost tf_crm]# vim uwsgi.ini注释版
[uwsgi]
# Django-related settings
# the base directory (full path)
# 填写crm项目的第一层绝对路径
chdir = /s25crm/tf_crm/
# Django's wsgi file
# 填写crm项目第二层的相对路径，找到第二层目录下的wsgi.py
# 这里填写的不是路径，是以上一个参数为相对，找到第二层项目目录下的wsgi.py文件
module = tf_crm.wsgi
# the virtualenv (full path)
# 填写虚拟环境解释器的第一层工作目录
home = /s25crm/s25_crm
# process-related settings
# master
master = true
# maximum number of worker processes
# 代表定义uwsgi运行的多进程数量，官网给出的优化建议是 2*cpu核数+1
# 如果是单进程，十万个请求，都丢给一个进程去处理
# 3个工作进程，十万个请求，就分给了3个进程去分摊处理
# 查看几核
# [root@localhost ~]# cat /proc/cpuinfo| grep "cpu cores"| uniq
# cpu cores : 4
processes = 9
# the socket (use the full path to be safe
# 使用此协议运行后台，就无法通过浏览器访问了，协议不一样
socket = 0.0.0.0:8000
# 线上不会用http参数，因为对后端是不安全的，使用socket参数是安全的连接，用nginx反向代理去访问
# 后端程序是运行在防火墙内部，外网是无法直接访问的
# 临时使用http参数，便于我们用浏览器调试访问
#http = 0.0.0.0:8000
# ... with appropriate permissions - may be needed
# chmod-socket = 664
# clear environment on exit

此时发现静态文件丢失，例如如下的静态文件
http://10.0.0.129/static/js/common.js
http://10.0.0.129/static/css/style.css
http://10.0.0.129/static/js/jquery.validate.min.js第一步：修改django的配置文件，收集所有的静态文件，放入一个统一管理的目录
(s25_crm) [root@localhost tf_crm]# vim /s25crm/tf_crm/tf_crm/settings.py # 添加如下内容
STATIC_ROOT='/s25static/' # 作用是定义一个统一管理的目录，收集所有crm的静态文件第二步：用命令收集静态文件
cd /s25crm/tf_crm
(s25_crm) [root@localhost tf_crm]# python3 manage.py collectstatic
(s25_crm) [root@localhost tf_crm]# cd /s25static/
