Heroku部署Springboot 博客项目

在前几天接触了heroku部署，一个国外免费的自动化部署工具，咱buddy也说它非常好，于是我就安静的沉下心来学习下这个工具，突然发现它真的很方便，只需要将代码push到heroku的git服务器上，在服务器上，git push命令会自动触发安装、配置和部署程序，连域名都会帮你创建好。

heroku 官网

准备工作

若想使用 Heroku,程序必须托管在 Git 仓库中。如果你的程序托管在像 GitHub 或 BitBucket 这样的远程 Git 服务器上,那么在本地 clone 程序后会创建一个本地 Git 仓库,可无缝用于 Heroku。如果你的程序没有托管在 Git 仓库中,那么必须在开发电脑上创建一个仓库。

注册账户

首先需要创建一个免费的Heroku帐户。注册后，邮箱就是你的登录账号。（注意qq邮箱是不能使用的）

安装Heroku CLI

这里是mac安装heroku客户端的方式

brew install heroku/brew/heroku

登录Heroku

$ heroku login
Enter your Heroku credentials.
Email: adam@example.com
Password (typing will be hidden):
Authentication successful.

按照提示登录就可以了，如果需要输入账号密码就直接输入邮箱和你的注册密码，网上很多教程需要输入的，但是我这里是因为刚刚在浏览器登录的，所以并没有让我输入账户密码。

heroku: Press any key to open up the browser to login or q to exit:

这里可以把你的 SSH 公钥上传到 Heroku，这一点很重要,上传后才能使用 git push 命令。正常情况下,login 命令会自动创建并上传 SSH 公钥。

要检查是否已添加密钥，可以运行

heroku keys

如果没有，可以通过运行手动添加它。

heroku keys:add

有关SSH密钥的更多信息，请参阅“ 管理SSH密钥”。

准备项目

这里我使用的是halo博客部署，这里只需要将本地代码提交。

git init
git add .
git commit -m "first commit"

之后，创建一个heroku app

heroku create
Creating app... done, ⬢ radiant-thicket-94286
https://radiant-thicket-94286.herokuapp.com/ | https://git.heroku.com/radiant-thicket-94286.git

这里可以给项目重命名下

heroku apps:rename springboot-tao-blog
Renaming radiant-thicket-94286 to springboot-tao-blog... done
https://springboot-tao-blog.herokuapp.com/ | https://git.heroku.com/springboot-tao-blog.git
Git remote heroku updated
 ▸    Don't forget to update git remotes for all other local checkouts of the app.

上传代码

push代码会触发部署动作，这个网站由于在国外，所以时间会较长，稍微等待...

git push heroku master
