技术栈:supervisor + nginx + uwsgi + django + virtualenv + mariadb
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

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
[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
vacuum = true
[uwsgi]
chdir = /s25crm/tf_crm/
module = tf_crm.wsgi
home = /s25crm/s25_crm
master = true
processes = 9
socket = 0.0.0.0:8000
vacuum = true
(s25_crm) [root@localhost tf_crm]# which uwsgi
/s25crm/s25_crm/bin/uwsgi
(s25_crm) [root@localhost tf_crm]# ls
app01 manage.py static templates tf_crm uwsgi.ini
(s25_crm) [root@localhost tf_crm]# pwd
/s25crm/tf_crm
vim /etc/supervisord.conf #修改如下参数
[program:s25crm]
command=/s25crm/s25_crm/bin/uwsgi --ini /s25crm/tf_crm/uwsgi.ini
autostart=true ; 在supervisord启动的时候也自动启动
startsecs=10 ; 启动10秒后没有异常退出,就表示进程正常启动了,默认为1秒
autorestart=true ; 程序退出后自动重启,可选值:[unexpected,true,false],默认为unexpected,表示进程意外杀死后才重启
stopasgroup=true ;默认为false,进程被杀死时,是否向这个进程组发送stop信号,包括子进程
killasgroup=true ;默认为false,向进程组发送kill信号,包括子进程
[program:s25crm]
command=/s25crm/s25_crm/bin/uwsgi --ini /s25crm/tf_crm/uwsgi.ini
autostart=true
startsecs=10
autorestart=true
stopasgroup=true
killasgroup=true
# 【supervisor无法正常启动,立即去检查 supervisord.conf里面定义的任务参数是否正确】
(s25_crm) [root@localhost tf_crm]# supervisord -c /etc/supervisord.conf
Unlinking stale socket /tmp/supervisor.sock
(s25_crm) [root@localhost tf_crm]# supervisorctl -c /etc/supervisord.conf
s25crm RUNNING pid 107727, uptime 0:00:52
supervisor> status
s25crm RUNNING pid 107727, uptime 0:01:16
此时浏览器访问 10.0.0.129:8000
由于协议不通,故出现如下页面
(s25_crm) [root@localhost tf_crm]# vim /opt/tngx232/conf/nginx.conf
server {
listen 80;
server_name localhost;
# 这是一个局部的变量,只对当前这个server{}代码块生效,编码设置为utf-8
charset utf-8;
error_page 404 /40x.html;
# 这里的locaiton路径匹配,如果你写的是root参数,就是一个web站点功能
# 基于uwsgi协议的一个高性能的反向代理转发,新的参数
location / {
# 当请求发送给 10.0.0.129:80的时候
# 通过uwsgi_pass把请求转发给后端的uwsgi服务器
uwsgi_pass 0.0.0.0:8000;
# 这个参数,是固定的,是添加一些转发请求头内容
include uwsgi_params;
}
}
server {
listen 80;
server_name localhost;
charset utf-8;
error_page 404 /40x.html;
location / {
uwsgi_pass 0.0.0.0:8000;
include uwsgi_params;
}
}
(s25_crm) [root@localhost tf_crm]# nginx -t
nginx: the configuration file /opt/tngx232//conf/nginx.conf syntax is ok
nginx: configuration file /opt/tngx232//conf/nginx.conf test is successful
(s25_crm) [root@localhost tf_crm]# nginx -s reload
浏览器访问 10.0.0.129/login/
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
(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
cd /s25crm/tf_crm
(s25_crm) [root@localhost tf_crm]# python3 manage.py collectstatic
(s25_crm) [root@localhost tf_crm]# cd /s25static/
(s25_crm) [root@localhost s25static]# ls
admin css imgs js plugins
nginx找到crm的静态文件原理图
(s25_crm) [root@localhost s25static]# vim /opt/tngx232/conf/nginx.conf
server {
listen 80;
server_name localhost;
# 这是一个局部的变量,只对当前这个server{}代码块生效,编码设置为utf-8
charset utf-8;
error_page 404 /40x.html;
# 这里的locaiton路径匹配,如果你写的是root参数,就是一个web站点功能
# 基于uwsgi协议的一个高性能的反向代理转发,新的参数
location / {
# 当请求发送给 10.0.0.129:80的时候
# 通过uwsgi_pass把请求转发给后端的uwsgi服务器
uwsgi_pass 0.0.0.0:8000;
# 这个参数,是固定的,是添加一些转发请求头内容
include uwsgi_params;
}
# nginx的location{}代码块用于匹配nginx的url,对于静态文件的匹配,可以按如下配置
# 当请求url是 10.0.0.129:80/static/js
# 10.0.0.129:80/static/css
# 10.0.0.129:80/static/admin/admin.js
# ......
# 如此之类以 /static 开头的url,都告诉nginx去Linux的 /s25static 目录下寻找资料,也就找到所有的 js、css了
location /static {
alias /s25static;
}
}
server {
listen 80;
server_name localhost;
charset utf-8;
error_page 404 /40x.html;
location / {
uwsgi_pass 0.0.0.0:8000;
include uwsgi_params;
}
location /static {
alias /s25static;
}
}
