Deploy to ECS and Automation

Xshell连接阿里云服务器详细: https://blog.csdn.net/weixin_43122090/article/details/103548798

修改Aliyun安全策略, enable port : https://developer.aliyun.com/article/767328

虚拟机桥接方式却无法连通：firewall

#查看firewall状态
systemctl status firewalld.service

#停止firewall
systemctl stop firewalld.service

#禁止firewall开机启动
systemctl disable firewalld.service

1. automate: public ip:5000 -> trigger deploy.sh -> pull the latest code and start ./webserver

• deplpy-level dir to manage auto deployment process
• business-level dir for business

deploy.sh

#! /bin/sh
kill -9 $(pgrep webserver)
cd $(pwd)/newweb/
git pull git@github.com:sabertobihwy/newweb.git
cd webserver/
chmod +x webserver  -- this is error! this will cause local changes -> unable to git pull again!!! 
                    -- instead we use  `git add --chmod=+x webserver/webserver`
./webserver &

deployServer.go:  launch deploy.sh 

func relaunch() {
    cmd := exec.Command("sh", "./deploy.sh")
    err := cmd.Start()
    if err != nil {
        log.Fatal(err)
    }
    err = cmd.Wait() // release resources
}

func firstPage(w http.ResponseWriter, r *http.Request) {
    io.WriteString(w, "<h1>Automatically!</h1>") 
    relaunch()
}

--deploy.sh (by using  cp newweb/deploy.sh deploy.sh ) 

--deploywebServer ( cp newweb/deploywebServer/deploywebServer deploywebServer )

--newweb/

　　---deploy.sh

       ---deploywenServer/

　　---webserver/

attention!! when committing the .exe, remember to --chmod=+x 

2. using webhook on github  : local push  -> trigger invoking public ip:5000 -> trigger deploy,sh

 in this case the ip must be open to public, not local ip
