node-exporter pprof漏洞处理（ansible批量修复）

pprof漏洞

访问node-exporter， IP:9100/debug/pprof
node-exporter版本，1.8.2
出现下边的页面就说明有漏洞

重新编译生成可执行文件

git clone [https://github.com/prometheus/node_exporter.git](https://github.com/prometheus/node_exporter.git)
cd node_exporter
git checkout v1.8.2
vim node_exporter.go

make build

替换

然后会在当前目录下生成 node_exporter，替换原先二进制文件，再重启服务即可

ansible批量替换
