示例
目標(biāo):把服務(wù)器CentOS上的redis數(shù)據(jù)復(fù)制到Mac機(jī)上
步驟:
在CentOS上找dump文件位置
vi /etc/redis.confdbfilename dump.rdb dir /var/lib/redis
說明文件在
/var/lib/redis/dump.rdb
在mac上查找dump文件位置
vi /usr/local/etc/redis.confdbfilename dump.rdb dir /usr/local/var/db/redis
拷貝服務(wù)器上的dump.rdb到mac機(jī)器
scp root@dv:/var/lib/redis/dump.rdb ./
在mac上重啟Redis
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.redis.plist launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
PS:備份腳本
看如下腳本,
#! /bin/bashPATH=/usr/local/bin:$PATHredis-cli SAVEdate=$(date +"%Y%m%d")cp /var/lib/redis/6379/dump.rdb /data01/cache_backup/$date.rdbecho "done!"
有如上腳本,便可以cron等方式備份redis數(shù)據(jù)文件了。細(xì)節(jié)如下:
首先必須進(jìn)行SAVE, 因?yàn)閞edis的rdb文件并非總是內(nèi)存數(shù)據(jù)的完整鏡像,備份之前必須進(jìn)行SAVE,即向其發(fā)送SAVE命令,其次拷貝走其rdb文件即可。
rdb的具體路徑不一定是如上路徑,可以在redis配置文件中查找, /etc/redis/6379.conf
# The filename where to dump the DBdbfilename dump.rdb# The working directory.## The DB will be written inside this directory, with the filename specified# above using the 'dbfilename' configuration directive.## Also the Append Only File will be created inside this directory.## Note that you must specify a directory here, not a file name.dir /var/lib/redis/6379
