redis数据迁移之redis-shake,java基础入门答案

修改日志存储位置

log file,日志文件,不配置将打印到stdout (e.g. /var/log/redis-shake.log )

log.file =/opt/shake/logs/redis-shake.log

配置原redis库

source.address = 10.10.12.41:6379

密码没有为空 有则填写

source.password_raw =

source r

edis configuration.

used in dump, sync and rump.

source redis type, e.g. “standalone” (default), “sentinel” or “cluster”.

1. “standalone”: standalone db mode.

2. “sentinel”: the redis address is read from sentinel.

3. “cluster”: the source redis has several db.

4. “proxy”: the proxy address, currently, only used in “rump” mode.

源端redis的类型,支持standalone,sentinel,cluster和proxy四种模式,注意:目前proxy只用于rump模式。

source.type = standalone

ip:port

the source address can be the following:

1. single db address. for “standalone” type.

2. s e n t i n e l m a s t e r n a m e : {sentinel_master_name}:sentinelmastername:{master or slave}@sentinel single/cluster address, e.g., mymaster:master@127.0.0.1:26379;127.0.0.1:26380, or @127.0.0.1:26379;127.0.0.1:26380. for “sentinel” type.

3. cluster that has several db nodes split by semicolon(?. for “cluster” type. e.g., 10.1.1.1:20331;10.1.1.2:20441.

4. proxy address(used in “rump” mode only). for “proxy” type.

源redis地址。对于sentinel或者开源cluster模式,输入格式为"master名字:拉取角色为master或者slave@sentinel的地址",别的cluster

架构,比如codis, twemproxy, aliyun proxy等需要配置所有master或者slave的db地址。

source.address = 10.10.12.41:6379

password of db/proxy. even if type is sentinel.

source.password_raw =

auth type, don’t modify it

source.auth_type = auth

tls enable, true or false. Currently, only support standalone.

open source redis does NOT support tls so far, but some cloud versions do.

source.tls_enable = false

input RDB file.

used in decode and restore.

if the input is list split by semicolon(?, redis-shake will restore the list one by one.

如果是decode或者restore,这个参数表示读取的rdb文件。支持输入列表,例如:rdb.0;rdb.1;rdb.2

redis-shake将会挨个进行恢复。

source.rdb.input = local

the concurrence of RDB syncing, default is len(source.address) or len(source.rdb.input).

used in dump, sync and restore. 0 means default.

This is useless when source.type isn’t cluster or only input is only one RDB.

拉取的并发度,如果是dump或者sync,默认是source.address中db的个数,restore模式默认len(source.rdb.input)。

假如db节点/输入的rdb有5个,但rdb.parallel=3,那么一次只会

并发拉取3个db的全量数据,直到某个db的rdb拉取完毕并进入增量,才会拉取第4个db节点的rdb,

以此类推,最后会有len(source.address)或者len(rdb.input)个增量线程同时存在。

source.rdb.parallel = 0

for special cloud vendor: ucloud

used in decode and restore.

ucloud集群版的rdb文件添加了slot前缀,进行特判剥离: ucloud_cluster。

source.rdb.special_cloud =

迁移目标库配置

配置原redis库

source.address = 10.10.12.42:6380

密码没有为空 有则填写

source.password_raw =

# 当源目的有重复key,是否进行覆写

# rewrite表示源端覆盖目的端。

# none表示一旦发生进程直接退出。

# ignore表示保留目的端key,忽略源端的同步key。该值在rump模式下没有用。

#默认none

#该值在rump模式下没有用。

key_exists = rewrite

target redis configuration. used in restore, sync and rump.

the type of target redis can be “standalone”, “proxy” or “cluster”.

1. “standalone”: standalone db mode.

2. “sentinel”: the redis address is read from sentinel.

3. “cluster”: open source cluster (not supported currently).

4. “proxy”: proxy layer ahead redis. Data will be inserted in a round-robin way if more than 1 proxy given.

目的redis的类型,支持standalone,sentinel,cluster和proxy四种模式。

target.type = standalone

ip:port

the target address can be the following:

1. single db address. for “standalone” type.

2. s e n t i n e l m a s t e r n a m e : {sentinel_master_name}:sentinelmastername:{master or slave}@sentinel single/cluster address, e.g., mymaster:master@127.0.0.1:26379;127.0.0.1:26380, or @127.0.0.1:26379;127.0.0.1:26380. for “sentinel” type.

3. cluster that has several db nodes split by semicolon(?. for “cluster” type.

4. proxy address. for “proxy” type.

target.address = 10.10.12.42:6380

password of db/proxy. even if type is sentinel.

target.password_raw =

auth type, don’t modify it

target.auth_type = auth

all the data will be written into this db. < 0 means disable.

target.db = -1

tls enable, true or false. Currently, only support standalone.

open source redis does NOT support tls so far, but some cloud versions do.

target.tls_enable = false

output RDB file prefix.

used in decode and dump.
