nebula-graph-br-bin

nebula graph backup&restore script (use snapshot)

基于nebula-graph snapshot的备份恢复脚本

snapshot说明：https://docs.nebula-graph.com.cn/2.0.1/7.data-security/3.manage-snapshot/

nebula-console说明：https://docs.nebula-graph.com.cn/2.0.1/2.quick-start/3.connect-to-nebula-graph/

使用方式

！！！恢复功能restore需要配置，脚本服务器与nebula-graph各个节点的ssh免密登录

用法:

  备份
  ./nebula_br.sh backup [nebulahost] [port] [user] [password]

  删除备份
  ./nebula_br.sh delete [nebulahost] [port] [user] [password] [snapshotname]

  恢复到某个版本
  ./nebula_br.sh restore [nebulahost] [port] [user] [password] [snapshotname] [restartnebulacommand]

  查看所有备份
  ./nebula_br.sh show [nebulahost] [port] [user] [password]

nebulahost : graphd服务所在地址。 example：localhost, 192.168.78.12

port : graphd服务所使用端口. example：9669

user : 设置Nebula Graph账号的用户名。未启用身份认证时，用户名可以填写任意字符。

password : 设置用户名对应的密码。未启用身份认证时，密码可以填写任意字符。

snapshotname : snapshot名称

restartnebulacommand : 你重启nebula-graph的脚本命令，在回滚时重启服务使用

示例

backup:

[root@test nebula-br]# ./nebula_br.sh backup nebula-graph-1 9669 1 1
nebula-consle is ok!
2021/07/15 16:08:49 [INFO] connection pool is initialized successfully
backup success! 

show:

[root@test nebula-br]# ./nebula_br.sh show nebula-graphd1 9669 1 1
nebula-consle is ok!
2021/07/15 16:10:32 [INFO] connection pool is initialized successfully

result:

finish!

delete

[root@test nebula-br]# ./nebula_br.sh delete nebula-graphd1 9669 1 1 SNAPSHOT_2021_07_15_10_27_36

注意事项

1. 脚本在第一次使用时会下载nebula-console源码并进行编译，请确保你的机器存在go.

   如果编译不成功，可在脚本同级目录下创建nebula-console文件夹，将官方编译好的可执行文件，放入其中。并将文件名称改为nebula-console

2. 回滚恢复操作需要在nebula-graph的各个节点操作，因此需要：执行脚本的机器能免密登录到各个nebula-graph节点
