prometheus 监控服务器性能

参考地址：https://www.cnblogs.com/momoyan/p/11520676.html
docker安装执行下列命令即可

docker run -d --net="host" --pid="host" --name=node-exporter -v "/:/host:ro,rslave" prom/node-exporter --path.rootfs /host --web.listen-address=":19100"

非docker安装执行下列四步

第一步

下载 node_exporter，下载地址
https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

第二步

上传到服务器 /opt/exporter下
解压： tar -xvzf node_exporter-0.14.0.linux-amd64.tar.gz

第三部

进入解压后的文件夹，执行命令：
./node_exporter --web.listen-address=:19100 &

然后在服务器上开放19100 端口，测试用ip+19100端口即可访问到数据
contOS6 版本的防火墙重启 ： /etc/init.d/iptables restart 
contOS7 版本的防火墙重启 ：service iptables restart

第四步
