来源：互联网发布：flotherm软件免费下载编辑：程序博客网时间：2024/06/16 05:07

环境：

OS:Red Hat Linux As 5

DB:redis-2.8.19

---------------------------------------------主库安装--------------------------------------------

[root@node1 redis]#tar xzf redis-2.8.19.tar.gz
[root@node1 redis]#cd redis-2.8.19
[root@node1 redis]#make

启动redis
[root@node1 redis]#cd src
[root@node1 src]# ./redis-server

---------------------------------------------从库安装--------------------------------------------

1.安装跟主机同版本的redis
[root@node1 redis]#tar xzf redis-2.8.19.tar.gz
[root@node1 redis]#cd redis-2.8.19
[root@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
[root@node1 redis]#cd src
[root@node1 src]# ./redis-server /soft/redis/redis/redis.conf

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

从库上操作
[root@node2 src]# ./redis-cli
127.0.0.1:6379> get yourname
"test"
127.0.0.1:6379>
