-bash: etcdctl: command not found

1、执行etcd备份，发现命令找不到，接下来安装命令

wget "https://github.com/coreos/etcd/releases/download/v3.3.9/etcd-v3.3.9-linux-amd64.tar.gz"

解压

tar -xvf etcd-v3.3.9-linux-amd64.tar.gz

移动命令文件

sudo mv etcd-v3.3.9-linux-amd64/etcd* /usr/local/bin/

 2、安装完成命令后，执行备份

[root@master01 ~]# ETCDCTL_API=3 etcdctl snapshot save /data/backup/etcd-snapshot.db  \
> --endpoints=https://127.0.0.1:2379 --cacert=/etc/kubernetes/pki/etcd/ca.crt \
> --cert=/etc/kubernetes/pki/etcd/server.crt --key=/etc/kubernetes/pki/etcd/server.key
Snapshot saved at /data/backup/etcd-snapshot.db
