linux下安装
1.下载 wget https://releases.hashicorp.com/consul/1.7.3/consul_1.7.3_linux_amd64.zip 2.解压 unzip consul_1.7.3_linux_amd64.zip 3.移动到全局变量 mv consul /usr/local/bin/consul 4.查看 consul --version 5.启动（使用开发模式启动） 1）consul agent -dev //localhost访问 2）consul agent -dev -client 0.0.0.0 -ui //IP访问 6.访问 netstat -nptl //查看端口8500 ps -ef|grep consul //查看进程编号 kill -15 进程号 //杀死进程
windows下 下载完解压就可以看到consul.exe了 双击运行。进入命令行窗口 查看版本 consul --version 开发者模式启动 consul agent -dev 访问 http;//localhost:8500
