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 rubyrequire 'rubygems'
require 'bundler/setup'
require 'sinatra'get '/' do"<h1>Hello From Ruby on Fly!</h1>"
endget '/:name' do"<h1>Hello From Ruby on Fly!</h1></br>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
*          PID: 300873
* 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+08:00app = "1234"kill_signal = "SIGINT"

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
