make install after the installation is complete, an executable file is generated in the next few / usr / local / bin directory, their role are: 
Redis-Server: the Redis server initiates a process 
redis-cli: Redis client operating tool. Telnet can also be used to operate according to its plain-text protocol 
redis-benchmark: Redis performance testing tool 
redis-check-aof: data recovery tool 
redis-check-dump: checking export tool

2, modify the configuration file Redis

Here with a main library, two from the library Example: 
Create a profile :( main library file location is also the best place to find convenient installation directory) 
I placed /usr/local/redis-3.0 unity in the configuration file .0 / conf, as shown in the following figure: 
 
Redis-6379.conf profile as follows:

#主表的配置文件
# Redis使用后台模式
daemonize yes
# 注释以下内容开启远程访问
# bind 127.0.0.1
# 修改启动端口为6379
port 6379 # 修改pidfile指向路径--Redis以守护进程方式运行时把pid写入文件 pidfile /usr/local/redis-3.0.0/conf/redis_6379.pid #数据库的存放位置 自己定义 dir /usr/local/redis-3.0.4/db/master/

3, start the Redis service

Use the newly created configuration file to start the service redis

/usr/local/bin/redis-server /usr/local/redis-3.0.4/conf/redis-6379.conf 
/usr/local/bin/redis-server /usr/local/redis-3.0.4/conf/redis-6380.conf /usr/local/bin/redis-server /usr/local/redis-3.0.4/conf/redis-6381.conf

Redis check whether a successful start, as shown below represents the start successfully.

ps -ef|grep redis

4, the master Verify

Use redis redis-cli to connect the local view. First of all clients connected redis-6379 end:

#默认连接6379端口
/usr/local/bin/redis-cli

An insert data in the main database 
 
is switched to from the library. Check whether the data exists. And there is a master-slave configuration takes effect.

#连接6380从库
/usr/local/bin/redis-cli -p 6380

Or enter the command content directly in redis

127.0.0.1:6379> info replication

FIG effect as follows: 
 
the master is done from this Redis configured.
