etcdctl backup --data-dir /var/lib/etcd/default.etcd --backup-dir /root/etcd71
etcd备份
使用etcd自带命令etcdctl进行etc备份，脚本如下：
#!/bin/bash
date_time=`date +%Y%m%d`
etcdctl backup --data-dir /var/lib/etcd/default.etcd --backup-dir /root/etcd71-
${date_time}.etcd
tar cvzf etcd71-
${date_time}.tar.gz etcd71-${date_time}.etcd
find /root/*.etcd -ctime +7 -exec rm -r {} \;
find /root/*.gz -ctime +7 -exec rm -r {} \;
# 打包备份数据
tar cvzf etcdback-
恢复etcd数据
# 单机运行
etcd --data-dir=/var/lib/etcd/default.etcd --force-new-cluster &
# 查看id
etcdctl member list

-H "Content-Type:application/json" -d ‘{"peerURLs":["http://127.0.0.1:2379"]}‘
