1. 安装 ubuntu 更新 sudo apt-get update sudo apt-get -y upgrade 2. 下载 Go 二进制文件 接下来的逻辑步骤是下载 Go 二进制文件，最新软件将在 golang.org/dl/ 上提供，并在终端中的命令下方安装 ubuntu 运行的版本 mkdir tmp cd /tmp wget https://dl.google.com/go/go1.15.6.linux-amd64.tar.gz 解压缩下载的 tar，然后安装到系统中的所需位置。但是通常遵循文档最好将其安装在 /user/local/go 下。在终端中运行以下命令进行安装 sudo tar -xvf go1.15.6.linux-amd64.tar.gz sudo mv go /usr/local 3. 环境设置 我们正在设置的三个 Go 语言环境变量是 GOROOT，GOPATH 和 PATH。 GOROOT 是 Go 在机器中安装的路径 GOPATH 是工作目录的位置。 编辑.bashrc，添加以下几行 # loads go export GOROOT="/usr/local/go" export GOPATH="$HOME/go" export PATH="$GOPATH/bin:$GOROOT/bin:$PATH" export GOPROXY="https:

Netcat bidirectional communication

问题 The goal which I am attempting to achieve is for a client to send the following command to a server: echo "Hello" | nc IP Port Upon receiving the "Hello" keyword, the server which is listening using: nc -nlp port should then send a response "Holla" back to the client. I have tried the following, none of which work in my instance: run a command conditionally with netcat and grep Is a conditional response possible with netcat How to respond conditionally based on the request when using netcat

阿里云ECS服务器前后端项目部署

由 荒凉一梦 提交于 2020-12-22 15:32:25
最近自己写了一个小项目，想把它部署在服务器上以便实时查看，在此记录一下自己的部署过程以及在部署过程中遇到的问题，方便日后查看。 参考： www.kovli.com/2017/09/19/… 作者： Kovli 一、购买云服务器 目前国内占有率比较高的就是 腾讯云 和 阿里云 ，这里本人选择的是阿里云的ECS云服务器。（吐槽一下，普通价格真的比学生价贵太多了） 如果在购买时没有设置ssh密码，可以进入ECS控制台-示例列表-重置密码中设置密码。把IP地址中的公网IP记录下来，后续会用到。 二、登录服务器 选择一款SSH工具登录远程服务器。常见的SSH工具有putty、xshell、xftp、SecureCRT等。这里我选择了putty，因为它简单易用，且不需要安装。 下载好putty之后打开putty.exe，登录界面如下： 在图中所示Host Name的位置输入之前记录的公网IP，在Saved Sessions方框内输入会话名，并点击Save即可保存当前设置，以方便下次登录。 点击Open，进入命令行界面。在这之前，可能会有以下提示： 点击“是”生成一个Key即可。 然后Putty即可连接到你的远程服务器（一般Linux）。 输入用户名和密码，即可远程登录。忘记密码的可以到管理平台中重置密码。 验证成功之后，即可进入以下界面： 接下来的操作就和在服务器本身上操作一样了。 三
