redis配置主从

鸦鸦

　　环境：
　　OS:Red Hat Linux As 5
　　DB:redis-2.8.19
　　---------------------------------------------主库安装--------------------------------------------
　　[iyunv@node1 redis]#tar xzf redis-2.8.19.tar.gz
[iyunv@node1 redis]#cd redis-2.8.19
[iyunv@node1 redis]#make
　　启动redis
[iyunv@node1 redis]#cd src
[iyunv@node1 src]# ./redis-server
　　

　　

　　---------------------------------------------从库安装--------------------------------------------
　　1.安装跟主机同版本的redis
[iyunv@node1 redis]#tar xzf redis-2.8.19.tar.gz
[iyunv@node1 redis]#cd redis-2.8.19
[iyunv@node1 redis]#make
　　
2.配置redis.conf文件
在安装的目录下找到redis.conf文件,编辑该文件
找到如下项，将主机的ip地址和端口口填上
slaveof  
如：
slaveof 192.168.56.101 6379
　　

　　3.启动redis
[iyunv@node1 redis]#cd src
[iyunv@node1 src]# ./redis-server /soft/redis/redis/redis.conf

　　4.验证
主库上操作
[iyunv@node1 src]# ./redis-cli
127.0.0.1:6379> set yourname test
OK
127.0.0.1:6379>
　　从库上操作
[iyunv@node2 src]# ./redis-cli
127.0.0.1:6379> get yourname
"test"
127.0.0.1:6379>
