检查配置命令行

e:web-server-for-winnginx-1.13.8>nginx -t

nginx: the configuration file e:web-server-for-winnginx-1.13.8/conf/nginx.conf syntax is ok

nginx: configuration file e:web-server-for-winnginx-1.13.8/conf/nginx.conf test is successful

启动nginx程序

e:web-server-for-winnginx-1.13.8>nginx.exe

2.angular 5

1). install nodejs

node-v8.9.3-x64.msi

2).setting prog

由于 npm 官网镜像国内访问太慢，这里我使用了淘宝的npm镜像，安装方法如下：

$ npm install -g cnpm --registry=https://registry.npm.taobao.org

执行后我们就可以使用 cnpm 命令来安装模块：

$ npm install -g @angular/cli@latest

项目初始化

新建项目

E:&;ng new pgmon-web --routing

选项：

--routing，附加路由功能

E:&;cd pgmon-web

新建组件(默认每个组件单独生成文件夹)

E:pgmon-web>ng g c login

E:pgmon-web>ng g c dashboard

新建服务(每个服务单独生成生成文件夹)

E:pgmon-web> ng g s --flat false AuthGuard

create src/app/auth-guard/auth-guard.service.spec.ts (393 bytes)

create src/app/auth-guard/auth-guard.service.ts (115 bytes)

E:pgmon-web> ng g s --flat false AuthenticationService

create src/app/authentication-service/authentication-service.service.spec.ts (465 bytes)

create src/app/authentication-service/authentication-service.service.ts (127 bytes)

E:pgmon-web> ng g s --flat false UserService

create src/app/user-service/user-service.service.spec.ts (405 bytes)

create src/app/user-service/user-service.service.ts (117 bytes)

E:pgmon-web>

安装node模块

E:pgmon-web> npm install bootstrap@next

选项：

@next，使用最新版本4.0.0-beta.2，否则使用版本3

npm WARN bootstrap@4.0.0-beta.2 requires a peer of jquery@1.9.1 - 3 but none is installed. You must install peer dependencies yourself.

npm WARN bootstrap@4.0.0-beta.2 requires a peer of popper.js@^1.12.3 but none is installed. You must install peer dependencies yourself.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modulesfsevents):

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

+ bootstrap@4.0.0-beta.2

added 115 packages,removed 5 packages and updated 2 packages in 23.201s

E:pgmon-web>

加载bootstrap到angular组件

E:pgmon-web>目录，编辑.angular-cli.json文件

"styles": [

"styles.css",

"../node_modules/bootstrap/dist/css/bootstrap.css"

],

生成生产环境部署文件,E:pgmon-webdist

E:pgmon-web>ng build --prod

3.golang

软件列表：

go1.9.windows-amd64.msi

Git-2.14.1-32-bit.exe

Sublime Text Build 3143 x64 Setup.exe

进入命令行

Dep is a tool for managing dependencies for Go projects

Usage: "dep [command]"

Commands:

init Initialize a new project with manifest and lock files

status Report the status of the project's dependencies

ensure Ensure a dependency is safely vendored in the project

prune Prune the vendor tree of unused packages

version Show the dep version information

Examples:

dep init set up a new project

dep ensure install the project's dependencies

dep ensure -update update the locked versions of all dependencies

dep ensure -add github.com/pkg/errors add a dependency to the project

Use "dep help [command]" for more information about a command.

安装项目依赖包(安装前必须先进行dep初始化)

E:go-websrcapp> e:go-webbindep ensure

运行项目

E:go-websrcapp> go run main.go

打开浏览器，

输入"localhost/api/status"

或者"localhost:8000/api/status"

browser output:

{"data":"Golang API Server run successfull."}
