tar -xf redis-3.2.0.tar.gz

cd redis-3.2.0

make 

cd redis-3.2.0/src/

cp redis-server redis-cli redis-benchmark /usr/local/redis/bin/

echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

/sbin/sysctl -p

创建master 配置文件 

             拷贝 /redis-3.2.0/redis.conf或者复制下面 

vim /usr/local/redis/etc/redis.conf

requirepass redis123          #密码

                                      

         

创建slave配置文件 安装和前面一样

vim /usr/local/redis/etc/redis.conf

bind 192.168.80.63

protected-mode yes

port 6379

hz 10

aof-rewrite-incremental-fsync yes

slaveof 192.168.80.62 6379    #映射master 

masterauth redis123         #连接密码

                          

分别启动master和slave服务

/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf 

测试是否同步 

master 运行 /usr/local/redis/bin/redis-cli -h 192.168.80.62 -a redis123 set han 123456

slave 查看 /usr/local/redis/bin/redis-cli -h 192.168.80.63 get test

停止服务 /usr/local/redis/bin/redis-cli -h 192.168.80.62 -a redis123 -p 6379 shutdown 

无密码停止服务  /usr/local/redis/bin/redis-cli -p 6379 shutdown

备份数据

/usr/local/redis/bin/redis-cli -p 6379 save  无密码

/usr/local/redis/bin/redis-cli -h 192.168.80.62 -a redis123 -p 6379 save  有密码

恢复  cp /data/dbcache/dump.rdb 到目录 即可
