etcd數據庫備份與還原

# 備份 etcd數據

etcdctl backup --data-dir /var/lib/etcd/default.etcd --backup-dir /root/etcd71

 

etcd備份

使用etcd自帶命令etcdctl進行etc備份，腳本如下：

#!/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 {} \;

 

# 打包備份數據

tar cvzf etcdback-

 

恢復etcd數據

 

# 單機運行

etcd --data-dir=/var/lib/etcd/default.etcd --force-new-cluster &

 

# 查看id

etcdctl member list

1c4358be138c6d94: name=default peerURLs=htt ps://192.168.61.71:2380 clientURLs=http://localhost:2379 isLeader=true

 

# 數據同步

curl http://127.0.0.1:2379/v2/members/1c4358be138c6d94 -XPUT \

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

 

# 結束單機運行

pkill -9 etcd

 

# 重新啟動服務

systemctl restart etcd

systemctl status etcd
