一个简单的实现进程监控命令

package main
import "fmt"
import "strings"
import "net/http"
import "os/exec"
import "time"
func SendDingMsg(msg string) {
        //请求地址模板
        webHook := `https://oapi.dingtalk.com/robot/send?access_token=xxxx` //填写钉钉token
        content := `{"msgtype": "text",
                "text": {"content": "`+ msg + `"}
        }`
        //创建一个请求
        req, err := http.NewRequest("POST", webHook, strings.NewReader(content))
        if err != nil {
                fmt.Println(err)
        }

        client := &http.Client{}
        //设置请求头
        req.Header.Set("Content-Type", "application/json; charset=utf-8")
        //发送请求
        resp, err := client.Do(req)
        //关闭请求
        defer resp.Body.Close()

        if err != nil {
                // handle error
                fmt.Println(err)
        }
}

func runInLinux(cmd string) (string, error) {
        //fmt.Println("Running Linux cmd:" + cmd)
        result, err := exec.Command("/bin/sh", "-c", cmd).Output()
        if err != nil {
                return "", err
        }
        return strings.TrimSpace(string(result)), err
}
func CheckAllProRunning(){
    cmd := `xxxx`  检查命令
    start := `xxxxx`  启动命令
    pid ,err := runInLinux(cmd)
    fmt.Println(pid,err)
    if pid == ""{
        fmt.Println("进程不存在的!!!")
        SendDingMsg("项目:进程不存在的,已经开始重启")
        pid2,_ := runInLinux(start)
        if pid2 != ""{
            fmt.Println("进程启动成功!!!")
            SendDingMsg("项目:已经重启成功!!!")
       }
    }

}
func MonitorAllProRunning(){
        for{
                CheckAllProRunning()
                time.Sleep(60 * time.Second) //定义多长时间检查一次
        }
}
func main(){
    defer func() {
    if err := recover(); err != nil {
        fmt.Println("程序异常!!!")
    }
    }()
    MonitorAllProRunning()

}

打包并启动

go build checkprocess.go
nohup ./checkprocess &
