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,開發者要使用Git把程序推送到Heroku的Git服務器上。在服務器上,git push命令會自動觸發安裝、配置和部署程序。
Heroku使用名為Dyno的計算單元衡量用量,并以此為依據收取服務費用。最常用的Dyno類型是Web Dyno,表示一個Web服務器實例。程序可以通過使用更多的Web Dyno以增強其請求處理能力。另一種Dyno類型是Worker Dyno,用來執行后臺作業或其他輔助任務。
Heroku提供了大量的插件和擴展,可用于數據庫、電子郵件支持和其他很多服務。
準備程序
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 這樣的遠程 Git 服務器上,那么在本地 clone 程序后會創建一個本地 Git 倉庫,可無縫用于 Heroku。如果你的程序沒有托管在 Git 倉庫中,那么必須在開發電腦上創建一個倉庫。
注冊Heroku賬戶
安裝Heroku Toolbelt
Heroku Toolbelt是用于創建、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，/usr/local/heroku/bin將被添加到你的PATH環境變量
下載并安裝完成后，在 shell 中輸入heroku login，用創建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 命令會自動創建并上傳 SSH 公鑰。
創建程序
首先要確保程序在 Git 源碼控制系統中,然后在程序的頂級目錄下運行創建命令
在 Heroku 創建一個 app, 以便 Heroku 準備好接收你的代碼
當你創建一個 app, 將創建并關聯一個名為
heroku的遠端到你的本地倉庫
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
查看已創建的 app
? flask_blog git:(rest) ? heroku apps
=== My Apps
flask-blog-chaonet
默認 Heroku 會為你的 app 生成一個隨機的名字, 或者 你可以通過可選參數指定你的 app名。
現在，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
應用現在已經部署了，確保至少一個 app 的實例正在運行:
$ heroku ps:scale web=1
現在，可以用創建的包含 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:
$ heroku open
配置數據庫
Heroku 以擴展形式支持 Postgres 數據庫。少于 1 萬條記錄、同時連接數 20 、沒有緩存 、不允許fork/follow、沒有 Postgres 日志 的小型數據庫無需付費即可添加 到程序中。
添加 Postgres 到 Heroku 應用
通過命令行，將 Heroku Postgres 添加到一個 Heroku 應用：
? 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 設置將在 app 配置中生效，并包含用于訪問新提供的 Heroku Postgres 服務的 URL 。
這可以使用 heroku config 命令確認：
? 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 ？
- 建立主數據庫
Heroku 中的每個程序都支持多個數據庫。Heroku 建議使用 DATABASE_URL 變量保存主用數據庫信息。在單個數據庫的情況下，新的數據庫已經被指定到 DATABASE_URL 。
對于多個數據庫的情況，可以設置主用數據庫：
$ heroku pg:promote HEROKU_POSTGRESQL_RED
Promoting HEROKU_POSTGRESQL_RED_URL to DATABASE_URL... done
DATABASE_URL 環境變量的格式正是 SQLAlchemy 所需的。回想一下 config.py 腳本的內容,如果 設定了 DATABASE_URL,就使用其中保存的值,所以現在程序可以自動連接到 Postgres 數據庫。
- 查看數據庫使用信息
? flask_blog git:(rest) ? heroku pg:info

在 MAC 中安裝 Postgres
推薦在本地開發環境與生產環境運行相同的數據庫
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移到應用程序文件夾
雙擊，然后你的 MAC 中就有一個PostgreSQL服務器在運行了
- 使用 Postgres.app 的命令行工具
配置$PATH變量

? psycopg2-2.6.1 export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/latest/bin

配置 Python 用于 Postgres.app
在 Flask 中使用 Flask-SQLAlchemy 擴展時，可以直接在配置中定義，并由 app 讀取。
配置日志
任何寫到 標準輸出(stdout) 或標準錯誤(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據。
在運行時, 配置的變量被當做環境變量暴露給應用。
變量可以用Heroku的命令行工具配置，也可以在應用的Dashboard頁面的settings頁簽下配置。
配置電子郵件
Heroku 沒有提供 SMTP 服務器,所以我們要配置一個外部服務器。很多第三方擴展能把 適用于生產環境的郵件發送服務集成到 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服務器的用戶 名和密碼保存在環境變量中。
運行生產 Web 服務器
Heroku 沒有為托管程序提供 Web 服務器,相反,它希望程序啟動自己的服務器并監聽環 境變量 PORT 中設定的端口。
Flask 自帶的開發 Web 服務器表現很差,因為它不是為生產環境設計的服務器。有兩個 可以在生產環境中使用、性能良好且支持 Flask 程序的服務器,分別是Gunicorn和uWSGI。
若想在本地測試 Heroku 配置,我們最好在虛擬環境中安裝 Web 服務器。例如,可通過如下命令安裝 Gunicorn:
(venv) $ pip install gunicorn
若要使用 Gunicorn 運行程序,可執行下面的命令:
(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)
2013-12-03 09:52:10 [14363] [INFO] Using worker: sync
2013-12-03 09:52:10 [14368] [INFO] Booting worker with pid: 14368
manage:app 參數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實例的名字。注意,Gunicor 默認使用端口 8000,而 Flask 默認使用 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入 Heroku 創建的虛擬環境。
Heroku 的需求文件必須包含程序在生產環境中使用的所有通用依賴,以及支持 Postgres 數據庫的 psycopg2 包和 Gunicorn Web 服務器。
可以在需求文件中導入需求文件。
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文件內容的格式很簡單:在每一行中指定一個任務名,后跟一個冒號,然后是執行這個任務的命令。名為web的任務比較特殊任務,Heroku 使用這個任務啟動 Web 服務器。
Heroku 會為這個任務提供一個PORT環境變量,用于設定程序監聽請求的端口。如果設定了PORT變量, Gunicorn默認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 會運行 Procfile 中列出的所有任務。
程序可在 Procfile 中使用 web 之外的名字聲明其他任務,例如程序所需的其他服務。
使用 Heroku Local 進行本地測試
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
$ heroku local
heroku local是heroku local:start的簡寫，作用相同

可以在本地指定運行一個特定的進程類型，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
- 設置本地環境變量
在本地運行 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 在本地運行所需要的配置變量。當使用heroku local命令運行 APP，將會讀取.env文件，并且，每一個 名稱/值 對會被插入環境中，模仿實際的配置變量。
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 app 可能使用到與本地開發 app 不同的服務。例如，部署的生產 app 可能有一個引用
Heroku Postgres數據庫的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。
有時你可能想要在本地使用和 Heroku 環境相同的配置變量。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 服務器。在此之前,你要確保所有改動都已經提交到本地Git倉庫,然后執行git push heroku master把程序上傳到遠程倉庫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，報錯
