前端技術(shù)之：PrismaDemo服務(wù)部署過程記錄

安裝前提條件：

10年積累的成都網(wǎng)站設(shè)計(jì)、成都網(wǎng)站建設(shè)、外貿(mào)網(wǎng)站建設(shè)經(jīng)驗(yàn)，可以快速應(yīng)對客戶對網(wǎng)站的新想法和需求。提供各種問題對應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識你，你也不認(rèn)識我。但先做網(wǎng)站后付款的網(wǎng)站建設(shè)流程，更有靜海免費(fèi)網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。

1、已經(jīng)安裝了docker運(yùn)行環(huán)境

2、以下命令執(zhí)行記錄發(fā)生在MackBook環(huán)境

3、已經(jīng)安裝了PostgreSQL（我使用的是11版本）

4、Node開發(fā)運(yùn)行環(huán)境可以正常工作

首先需要通過Node包管理器安裝Prisma工具：

npm install -g prisma

然后，創(chuàng)建并初始化prisma項(xiàng)目：

prisma init prisma-study

? Set up a new Prisma server or deploy to an existing server? (Use arrow keys)

????????????????????????

??You can set up Prisma for local development (based on docker-compose)

? Use existing database??????Connect to existing database

??Create new database????????Set up a local database using Docker

????????????????????????

??Or deploy to an existing Prisma server:

??Demo server????????????????Hosted demo environment incl. database (requires login)

??Use other server???????????Manually provide endpoint of a running Prisma server

選擇使用已存在的數(shù)據(jù)庫（Use existing database）后，回車確認(rèn)選擇。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to?

??MySQL?????????????MySQL compliant databases like MySQL or MariaDB

? PostgreSQL????????PostgreSQL database

移動(dòng)上下箭頭鍵盤按鍵，選擇PostgreSQL后，再次回車確認(rèn)選擇。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? (Use arrow keys)

? No

??Yes (experimental - Prisma migrations not yet supported)

??

Warning: Introspecting databases with existing data is currently an experimental feature. If you find any issues, please report them here: https://github.co

m/prisma/prisma/issues

提示是否在選擇的數(shù)據(jù)庫中包含已存在數(shù)據(jù)。因?yàn)槭且粋€(gè)新庫，所以默認(rèn)選擇No，然后回車確認(rèn)。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host (localhost)

輸入數(shù)據(jù)庫的主機(jī)地址（注意，因?yàn)閜risma會(huì)運(yùn)行在docker中，所以，這兒需要配置宿主機(jī)IP，在類Linux系統(tǒng)上可以通過ifconfig命令來獲取IP）。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.111.152.242

? Enter database port (5432)

回車確認(rèn)使用默認(rèn)的Postgres數(shù)據(jù)庫的端口。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.xxx.xxx.xxx（此處為你的docker宿主機(jī)IP）

? Enter database port 5432

? Enter database user

輸入數(shù)據(jù)庫的用戶名后回車確認(rèn)。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.xxx.xxx.xxx（此處為你的docker宿主機(jī)IP）

? Enter database port 5432

? Enter database user postgres

? Enter database password

輸入數(shù)據(jù)庫用戶對應(yīng)的密碼后回車確認(rèn)。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.xxx.xxx.xxx（此處為你的docker宿主機(jī)IP）

? Enter database port 5432

? Enter database user postgres

? Enter database password study

? Enter database name

輸入使用的數(shù)據(jù)庫名稱后回車。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.xxx.xxx.xxx（此處為你的docker宿主機(jī)IP）

? Enter database port 5432

? Enter database user postgres

? Enter database password study

? Enter database name study

? Use SSL? (Y/n)

提示是否使用安全的網(wǎng)絡(luò)協(xié)議，這里選擇不使用（輸入n后回車）。

? Set up a new Prisma server or deploy to an existing server? Use existing database

? What kind of database do you want to deploy to? PostgreSQL

? Does your database contain existing data? No

? Enter database host 10.xxx.xxx.xxx（此處為你的docker宿主機(jī)IP）

? Use SSL? No

Connecting to database 18ms

? Select the programming language for the generated Prisma client

??Prisma TypeScript Client

??Prisma Flow Client

? Prisma JavaScript Client

??Prisma Go Client

??Don't generate

這里選擇產(chǎn)生JavaScript客戶端腳本（Prisma JavaScript Client）。

? Set up a new Prisma server or deploy to an existing server? Use existing database

Created 3 new files:??????????????????????????????????????????????????????????????????????????

??prisma.yml??????????Prisma service definition

??datamodel.prisma????GraphQL SDL-based datamodel (foundation for database)

??docker-compose.yml??Docker configuration file

Next steps:

??1. Open folder: cd prisma-study

??2. Start your Prisma server: docker-compose up -d

??3. Deploy your Prisma service: prisma deploy

??4. Read more about Prisma server:

?????http://bit.ly/prisma-server-overview

Generating schema... 20ms

Saving Prisma Client (JavaScript) at /Users/chunrong.liu/dev/study/prisma-study/generated/prisma-client/

至此，Prisma項(xiàng)目創(chuàng)建并初始化完畢。

接下來按昭Next steps下面的步驟提示執(zhí)行后續(xù)操作。

通過以下命令切換當(dāng)前目錄至剛創(chuàng)建的項(xiàng)目目錄（prisma-study）中。

cd prisma-study/

通過docker編排命令在docker中運(yùn)行prisma服務(wù)器。

docker-compose up -d

執(zhí)行后命令行提示如下：

Creating prisma-study_prisma_1 … done

此時(shí)服務(wù)運(yùn)行成功。

通過以下命令部署prisma服務(wù)。

$ prisma deploy

Creating stage default for service default ?

Deploying service `default` to stage `default` to server `local` 476ms

Changes:

??User (Type)

??+ Created type `User`

??+ Created field `id` of type `GraphQLID!`

??+ Created field `name` of type `String!`

??+ Created field `updatedAt` of type `DateTime!`

??+ Created field `createdAt` of type `DateTime!`

Applying changes 1.2s

Your Prisma GraphQL database endpoint is live:

??HTTP:??http://localhost:4466

??WS:????ws://localhost:4466

用流程器打開http://localhost:4466/鏈接地址，可以看到如下的UI界面。

運(yùn)行如下命令可以看到演練數(shù)據(jù)：

$ prisma playground

Serving playground at http://localhost:3000/playground

此時(shí)會(huì)自動(dòng)打開瀏覽器，并顯示如下界面：
