测试：
启动服务：
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

主服务器上执行：
/usr/local/redis/bin/redis-cli -h 192.168.1.100 -a redis123 set test 123456

从服务器上执行：
/usr/local/redis/bin/redis-cli -h 192.168.1.200 get test

启动脚本
# vim /etc/init.d/redis
#!/bin/sh
#
# redis - this script starts and stops the redis-server daemon
#
# chkconfig:   - 85 15
# description:  Redis is a persistent key-value database
# processname: redis-server
# config:      /usr/local/redis/etc/redis.conf
# pidfile:     /usr/local/redis/var/redis.pid

# Check that networking is up.

*)
 echo $"Usage: $0 {start|stop|restart|reload}"
 exit 2
esac

----------------------------------------------------------------------------------------------------
启动服务
# chmod 700 /etc/init.d/redis
# chkconfig --add redis
# service redis start

测试是否已启动
# /usr/local/redis/bin/redis-cli ping

性能测试
# /usr/local/redis/bin/redis-benchmark

关闭服务
# /usr/local/redis/bin/redis-cli -p 6379 shutdown

强制刷新数据到磁盘【Redis默认是异步写入磁盘的】
# /usr/local/redis/bin/redis-cli -p6379 save

---------------------------------------------------------------------------------------

不支持主主同步，也就是只能读写分离
