flyctl was installed successfully to /home/linlin/.fly/bin/flyctl
Manually add the directory to your $HOME/.bash_profile (or similar)
export FLYCTL_INSTALL="/home/linlin/.fly"
export PATH="$FLYCTL_INSTALL/bin:$PATH"
Run '/home/linlin/.fly/bin/flyctl --help' to get started
把这些代码放进文件中vim ~/.bashrc
export FLYCTL_INSTALL="/home/linlin/.fly"
export PATH="$FLYCTL_INSTALL/bin:$PATH"
flyctl auth login
登录进flyctl,再次运行新的APP就不需要登录了 ，直接创建运行就可以，运行命令rackup
把本地的一个简单的应用，部署到远程
例如一个sinatra 应用。
app.rb
#!/usr/bin/env ruby
require 'rubygems'
require 'bundler/setup'
require 'sinatra'
get '/' do
"Hello From Ruby on Fly!
"
end
get '/:name' do
"Hello From Ruby on Fly!
and hello to #{params[:name]}"
end
Gemfile:
source 'https://rubygems.org'
ruby '3.1.0'
gem 'sinatra'
gem 'puma'config.ru
require './app.rb'
run Sinatra::Application本地运行：$ rackup
Puma starting in single mode...
* Puma version: 5.6.4 (ruby 3.1.0-p0) ("Birdie's Version")
* Min threads: 0
* Max threads: 5
* Environment: development

* Listening on http://127.0.0.1:9292
* Listening on http://[::1]:9292
Use Ctrl-C to stop在远程运行 flyctl launch 注意在存在rb Gemfile文件夹内，此时是错误的文件夹
第一次在远程运行会出现加载较慢的情况，后续就不会了。
创建APP的时候，注意名称不要重复，不要下划线，可以选择公开与否和地区。
可以发现，在本地代码文件夹，会多出一个文件： fly.toml
# fly.toml file generated for 1234 on 2022-06-02T17:17:57+08:00

远程会出现项目，点击进入，是详情页面 可以看到详细的信息
如何做部署 flyctl deploy （前提：需要有个 fly.toml 文件）
执行命令，报错也没关系，因为不是在本地的docker运行的
点击1234hostname的网址并不能打开页面，那么出错了，应该在hi目录下增加文件fly.toml,重新运行刚才的命令
linlin@linlin-i5:/workspace/blog_fly/hi$ flyctl launch

运行的时间也是比较慢的，可以在远程看到新的APP已经是绿色的可以用了，
在详情页面也可以看到，增加了许多内容
点击hostname进入网址，可以看到我们写的app
添加参数，也可以正常使用
设置ssl 域名
点击图中的选项，可以进行域名的设置
保存之后，就可以输入域名进行访问了
不需要的项目可以进行删除,比如最先创建的错误的APP1234
