Heroku平臺
Heroku平臺的靈活性極高且支持多種編程語言。若想把程序部署到Heroku上,開發(fā)者要使用Git把程序推送到Heroku的Git服務(wù)器上。在服務(wù)器上,git push命令會自動觸發(fā)安裝、配置和部署程序。
Heroku使用名為Dyno的計(jì)算單元衡量用量,并以此為依據(jù)收取服務(wù)費(fèi)用。最常用的Dyno類型是Web Dyno,表示一個Web服務(wù)器實(shí)例。程序可以通過使用更多的Web Dyno以增強(qiáng)其請求處理能力。另一種Dyno類型是Worker Dyno,用來執(zhí)行后臺作業(yè)或其他輔助任務(wù)。
Heroku提供了大量的插件和擴(kuò)展,可用于數(shù)據(jù)庫、電子郵件支持和其他很多服務(wù)。
準(zhǔn)備程序
若想使用 Heroku,程序必須托管在 Git 倉庫中。如果你的程序托管在像 GitHub 或 BitBucket 這樣的遠(yuǎn)程 Git 服務(wù)器上,那么在本地 clone 程序后會創(chuàng)建一個本地 Git 倉庫,可無縫用于 Heroku。如果你的程序沒有托管在 Git 倉庫中,那么必須在開發(fā)電腦上創(chuàng)建一個倉庫。
注冊Heroku賬戶
安裝Heroku Toolbelt
Heroku Toolbelt是用于創(chuàng)建、管理Heroku上apps的命令行工具
heroku 的命令行客戶端將被安裝到/usr/local/heroku，同時(shí)，/usr/local/heroku/bin將被添加到你的PATH環(huán)境變量
下載并安裝完成后，在 shell 中輸入heroku login，用創(chuàng)建heroku賬號的email和密碼登陸
$ heroku login
Enter your Heroku credentials.
Email: adam@example.com
Password (typing will be hidden):
Authentication successful.
把你的 SSH 公鑰上傳到 Heroku，這一點(diǎn)很重要,上傳后才能使用 git push 命令。正常情況下,login 命令會自動創(chuàng)建并上傳 SSH 公鑰。
創(chuàng)建程序
首先要確保程序在 Git 源碼控制系統(tǒng)中,然后在程序的頂級目錄下運(yùn)行創(chuàng)建命令
在 Heroku 創(chuàng)建一個 app, 以便 Heroku 準(zhǔn)備好接收你的代碼
當(dāng)你創(chuàng)建一個 app, 將創(chuàng)建并關(guān)聯(lián)一個名為
heroku的遠(yuǎn)端到你的本地倉庫
apps:create [NAME] # create a new app 名稱必須以字母開始,只能包含小寫字母,數(shù)字和連字符, 而且名稱在 heroku 的所有程序中必須是唯一的
? flask_blog git:(rest) ? heroku apps:create flask-blog-chaonet
Creating flask-blog-chaonet... done, stack is cedar-14
https://flask-blog-chaonet.herokuapp.com/ | https://git.heroku.com/flask-blog-chaonet.git
Git remote heroku added
查看已創(chuàng)建的 app
? flask_blog git:(rest) ? heroku apps
=== My Apps
flask-blog-chaonet
默認(rèn) Heroku 會為你的 app 生成一個隨機(jī)的名字, 或者 你可以通過可選參數(shù)指定你的 app名。
現(xiàn)在，你可以向 Heroku 部署你的代碼了
$ git push heroku master # 必須將 本地 的 master push 到 heroku 的 master
應(yīng)用現(xiàn)在已經(jīng)部署了，確保至少一個 app 的實(shí)例正在運(yùn)行:
$ heroku ps:scale web=1
現(xiàn)在，可以用創(chuàng)建的包含 app 名稱的 URL 訪問 app. 有一個便捷的方法, 你可以像這樣打開web站點(diǎn):
$ heroku open
配置數(shù)據(jù)庫
Heroku 以擴(kuò)展形式支持 Postgres 數(shù)據(jù)庫。少于 1 萬條記錄、同時(shí)連接數(shù) 20 、沒有緩存 、不允許fork/follow、沒有 Postgres 日志 的小型數(shù)據(jù)庫無需付費(fèi)即可添加 到程序中。
添加 Postgres 到 Heroku 應(yīng)用
通過命令行，將 Heroku Postgres 添加到一個 Heroku 應(yīng)用：
? flask_blog git:(rest) ? heroku addons:create heroku-postgresql:hobby-dev
Creating postgresql-sinuous-8326... done, (free)
Adding postgresql-sinuous-8326 to flask-blog-chaonet... done
Setting DATABASE_URL and restarting flask-blog-chaonet... done, v3
Database has been created and is available
! This database is empty. If upgrading, you can transfer
! data from another database with pg:copy
Use `heroku addons:docs heroku-postgresql` to view documentation.
最低等級的業(yè)余版本有兩種方案 hobby-dev 和 hobby-basic
一旦 Heroku Postgres 被添加，一個 DATABASE_URL 設(shè)置將在 app 配置中生效，并包含用于訪問新提供的 Heroku Postgres 服務(wù)的 URL 。
這可以使用 heroku config 命令確認(rèn)：
? flask_blog git:(rest) ? heroku config -s | grep DATABASE_URL
DATABASE_URL=postgres://bjtrukgnhvnban:T0_N_OWYVz6NnasUwOf0FxVscO@ec2-54-83-52-71.compute-1.amazonaws.com:5432/d44ph8k76dl0h0
amazonaws ？
- 建立主數(shù)據(jù)庫
Heroku 中的每個程序都支持多個數(shù)據(jù)庫。Heroku 建議使用 DATABASE_URL 變量保存主用數(shù)據(jù)庫信息。在單個數(shù)據(jù)庫的情況下，新的數(shù)據(jù)庫已經(jīng)被指定到 DATABASE_URL 。
對于多個數(shù)據(jù)庫的情況，可以設(shè)置主用數(shù)據(jù)庫：
$ heroku pg:promote HEROKU_POSTGRESQL_RED
Promoting HEROKU_POSTGRESQL_RED_URL to DATABASE_URL... done
DATABASE_URL 環(huán)境變量的格式正是 SQLAlchemy 所需的。回想一下 config.py 腳本的內(nèi)容,如果 設(shè)定了 DATABASE_URL,就使用其中保存的值,所以現(xiàn)在程序可以自動連接到 Postgres 數(shù)據(jù)庫。
- 查看數(shù)據(jù)庫使用信息

在 MAC 中安裝 Postgres
推薦在本地開發(fā)環(huán)境與生產(chǎn)環(huán)境運(yùn)行相同的數(shù)據(jù)庫
使用Postgres.app，是在 Mac 下使用PostgreSQL的最簡單的方法
在postgresapp下載Postgres.app
解壓后將Postgres移到應(yīng)用程序文件夾
雙擊，然后你的 MAC 中就有一個PostgreSQL服務(wù)器在運(yùn)行了
- 使用 Postgres.app 的命令行工具

配置 Python 用于 Postgres.app
在 Flask 中使用 Flask-SQLAlchemy 擴(kuò)展時(shí)，可以直接在配置中定義，并由 app 讀取。
配置日志
任何寫到 標(biāo)準(zhǔn)輸出(stdout) 或標(biāo)準(zhǔn)錯誤(stderr) 的信息才會被 Heroku 抓取到日志，并在 Heroku 客戶端通過heroku logs命令查看。
config.py
# 輸出到 stderr，以便被 Heroku 抓取到 logs
import logging
from logging import StreamHandler
file_handler = StreamHandler()
file_handler.setLevel(logging.WARNING)
app.logger.addHandler(file_handler)
定義配置變量
Heroku 可以讓你在程序外部配置變量 —— 存儲類似加密密鑰或外部資源地址的數(shù)據(jù)。
在運(yùn)行時(shí), 配置的變量被當(dāng)做環(huán)境變量暴露給應(yīng)用。
變量可以用Heroku的命令行工具配置，也可以在應(yīng)用的Dashboard頁面的settings頁簽下配置。
配置電子郵件
Heroku 沒有提供 SMTP 服務(wù)器,所以我們要配置一個外部服務(wù)器。很多第三方擴(kuò)展能把 適用于生產(chǎn)環(huán)境的郵件發(fā)送服務(wù)集成到 Heroku 中,但對于測試和評估而言,使用繼承自 Config 基類的 mail 配置已經(jīng)足夠了。
由于直接把安全密令寫入腳本存在安全隱患,所以我們把訪問 mail SMTP服務(wù)器的用戶 名和密碼保存在環(huán)境變量中。
運(yùn)行生產(chǎn) Web 服務(wù)器
Heroku 沒有為托管程序提供 Web 服務(wù)器,相反,它希望程序啟動自己的服務(wù)器并監(jiān)聽環(huán) 境變量 PORT 中設(shè)定的端口。
Flask 自帶的開發(fā) Web 服務(wù)器表現(xiàn)很差,因?yàn)樗皇菫樯a(chǎn)環(huán)境設(shè)計(jì)的服務(wù)器。有兩個 可以在生產(chǎn)環(huán)境中使用、性能良好且支持 Flask 程序的服務(wù)器,分別是Gunicorn和uWSGI。
若想在本地測試 Heroku 配置,我們最好在虛擬環(huán)境中安裝 Web 服務(wù)器。例如,可通過如下命令安裝 Gunicorn:
(venv) $ pip install gunicorn
若要使用 Gunicorn 運(yùn)行程序,可執(zhí)行下面的命令:
(venv) $ gunicorn manage:app
2013-12-03 09:52:10 [14363] [INFO] Starting gunicorn 18.0
2013-12-03 09:52:10 [14363] [INFO] Listening at: http://127.0.0.1:8000 (14363)

manage:app 參數(shù)冒號左邊的部分表示定義程序的包或者模塊,冒號右邊的部分表示包中程序?qū)嵗拿?/code>。注意,Gunicor 默認(rèn)使用端口 8000,而 Flask 默認(rèn)使用 5000。
添加依賴需求文件
Heroku 從程序頂級文件夾下的 requirements.txt 文件中加載包依賴。這個文件中的所有依賴都會在部署過程中導(dǎo)入 Heroku 創(chuàng)建的虛擬環(huán)境。
Heroku 的需求文件必須包含程序在生產(chǎn)環(huán)境中使用的所有通用依賴,以及支持 Postgres 數(shù)據(jù)庫的 psycopg2 包和 Gunicorn Web 服務(wù)器。
可以在需求文件中導(dǎo)入需求文件。
requirements.txt
-r requirements/prod.txt
gunicorn==18.0
psycopg2==2.5.1
添加Procfile文件
Heroku 需要知道使用哪個命令啟動程序。命令在一個名為Procfile(沒有后綴)的特殊文件中指定。這個文件必須放在程序的頂級文件夾中。
web: gunicorn manage:app
Procfile文件內(nèi)容的格式很簡單:在每一行中指定一個任務(wù)名,后跟一個冒號,然后是執(zhí)行這個任務(wù)的命令。名為web的任務(wù)比較特殊任務(wù),Heroku 使用這個任務(wù)啟動 Web 服務(wù)器。
Heroku 會為這個任務(wù)提供一個PORT環(huán)境變量,用于設(shè)定程序監(jiān)聽請求的端口。如果設(shè)定了PORT變量, Gunicorn默認(rèn)就會使用其中保存的值,因此無需將其包含在啟動命令中。
部署程序后,Heroku 會運(yùn)行 Procfile 中列出的所有任務(wù)。
程序可在 Procfile 中使用 web 之外的名字聲明其他任務(wù),例如程序所需的其他服務(wù)。
使用 Heroku Local 進(jìn)行本地測試
Heroku Local作為Heroku Toolbelt的一部分, 自動被安裝。
- 在本地啟動所有在你的
Profile中定義的任務(wù)
$ heroku local
heroku local是heroku local:start的簡寫，作用相同

可以在本地指定運(yùn)行一個特定的進(jìn)程類型，例如web或worker
$ heroku local web
然后，你就可以在本地測試 app。使用Ctrl+C停止
- 設(shè)置本地環(huán)境變量
在本地運(yùn)行 APP，同樣需要輸入一系列 配置變量 作為 app 的配置。.env文件讓你可以收集 app 在本地運(yùn)行所需要的配置變量。當(dāng)使用heroku local命令運(yùn)行 APP，將會讀取.env文件，并且，每一個 名稱/值 對會被插入環(huán)境中，模仿實(shí)際的配置變量。
增加一個配置變量到你的.env文件：編輯.env文件，并在新的一行增加一個新name=value對。
由于.env文件中包含密碼和其他敏感的賬戶信息, 所以決不能將其添加到 Git 倉庫中，這個文件應(yīng)該只在存在于本地配置中。使用:echo .env >> .gitignore, 將.env文件列入 git 的忽略文件列表。
需要注意，你部署的生產(chǎn) app 可能使用到與本地開發(fā) app 不同的服務(wù)。例如，部署的生產(chǎn) app 可能有一個引用
Heroku Postgres數(shù)據(jù)庫的DATABASE_URL配置變量，但你的本地 app可能在.env文件中有一個引用本地安裝的Postgres的DATABASE_URL變量。
有時(shí)你可能想要在本地使用和 Heroku 環(huán)境相同的配置變量。對于每一個你想要添加到.env文件的配置變量，使用如下命令：
$ heroku config:get CONFIG-VAR-NAME -s >> .env
- 查看環(huán)境變量
使用heroku config查看 app 的所有配置變量。使用cat .env查看.env文件的內(nèi)容
- 另一個本地測試工具 Foreman
除了heroku local,原本的foreman也可以使用，但不再提供官方的支持，需要另外安裝。
Heroku Local has replaced Foreman in the Heroku Toolbelt
執(zhí)行 git push 命令部署
部署過程的最后一步是把程序上傳到 Heroku 服務(wù)器。在此之前,你要確保所有改動都已經(jīng)提交到本地Git倉庫,然后執(zhí)行git push heroku master把程序上傳到遠(yuǎn)程倉庫heroku。
上傳代碼，中間遇到一個坑，一開始從本地的rest分支向heroku的master推送，報(bào)錯
