技术栈:vue + nginx + uwsgi + django + mariadb + redis
vue打包之后,生成了dist静态文件夹 ,前端的静态文件,都在这里了,静态文件,都是丢给nginx直接去返回即可
vue的dist静态文件运行之后,能够立即看到路飞的首页内容了,此时还没有和后端的数据交互
当你在前端的单页面应用中,点击课程列表,向后台发送ajax请求,提交post
vue请求课程列表的post请求,应该是发给谁去处理的?
答案是DRF后台去处理的
注意在线上部署的架构图流程中,,django后台,是躲在了防火墙之后的,只能通过nginx反向代理去访问
路飞前后端分离部署的示意图
配置node的环境,用于 npm run build 对前端的vue代码进行打包
(s25_crm) [root@localhost ~]# mkdir /s25luffy
(s25_crm) [root@localhost ~]# cd /s25luffy/

# 这里特殊的是这个地址是node的二进制源码包,是已经编译完成了的node解释器
# 直接解压缩,配置PATH即可,无需再编译了
[root@localhost s25luffy]# wget https://nodejs.org/download/release/v8.6.0/node-v8.6.0-linux-x64.tar.gz
[root@localhost s25luffy]# ls

[root@localhost s25luffy]# tar -zxvf node-v8.6.0-linux-x64.tar.gz
# 添加node的环境变量,如下
[root@localhost s25luffy]# cd node-v8.6.0-linux-x64/

# 这里是vue页面运行之后,出发js的数据提交动作,向某个地址,发出了请求,这个地址对吗?
# 为什么不对呢?是因为vue向当前机器的本地去发送请求了,是错的
# 应该向后台服务器去发送请求
# 那么,应该发给谁呢?
# 应该发给刚才9000端口还是9005端口呢?
# 这里是数据提交地址,应该发给代理服务器,也就是9000端口,然后再通过9000端口,转发给uwsgi,也就是9005端口
批量修改的命令
是用于文本内容处理的强大命令,可以直接替换文件中的内容
类似notapad++的全局替换功能
# sed命令 -i参数是把替换结果写入到文件
# 's/127.0.0.1:8000/10.0.0.129:9000/g'
# s是替换指令 /你要替换的内容/替换之后的内容/ g是全局替换,global的意思
[root@localhost bin]# cd /s25luffy/
[root@localhost s25luffy]# ls
07-luffy_project_01 07-luffy_project_01.zip __MACOSX node-v8.6.0-linux-x64 node-v8.6.0-linux-x64.tar.gz
[root@localhost s25luffy]# cd 07-luffy_project_01/
[root@localhost 07-luffy_project_01]# ls
build config index.html package.json package-lock.json README.md src static
[root@localhost 07-luffy_project_01]# sed -i 's/127.0.0.1:8000/10.0.0.129:9000/g' src/restful/api.js
# 类似python项目要运行,需要安装pip3模块一样
# node项目要运行,也需要 npm install package.json # 安装模块
# 以下这个命令,是更换npm的源的含义,加速下载
# --registry https://registry.npm.taobao.org 这是临时更换淘宝源的含义
# 结尾什么都不跟上,默认是安装当前路径的 package.json文件
[root@localhost 07-luffy_project_01]# npm --registry https://registry.npm.taobao.org install
[root@localhost 07-luffy_project_01]# npm run build
由于在 https://www.cnblogs.com/zylyehuo/p/17684304.html 中80端口已经给crm项目用了,因此路飞需要换成81端口
