cd /opt && wget https://golang.org/dl/go1.13.10.linux-amd64.tar.gz
#解压至/usr/local
tar -zxvf go1.13.10.linux-amd64.tar.gz

创建/opt/gocode/{src,bin,pkg},用于设置GOPATH为/opt/gocode

export GOBIN=$GOPATH/bin #go install后生成的可执行命令存放路径
# 保存退出后source一下
source /etc/profile

执行go version

[root@localhost gocode]# go version
go version go1.13.10 linux/amd64

运行程序并打包

安装gin web框架

爬过梯子的可以直接安装,不再赘述如何爬梯子,如果没有爬梯子的话 需要设置下GOPROXY

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

阿里云
go env -w GO111MODULE=on
go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

安装gin依赖

go build alertGo.go

运行alertGo程序

###赋权
chmod 775 alertGo
###后台运行
nohup /root/prometheus/alertGo/alertGo > alertGo.log 2>&1 &
###查看端口进程
lsof -i:8088
###查看日志
tail -f alertGo.log

修改alertmanager-configmap.yaml

热更新prometheus

kubectl apply -f alertmanager-configmap.yaml
###alertmanager clusterIP
curl -X POST http://10.1.229.17/-/reload

然后触发报警,钉钉就可以正常收取了,
