　　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

# pidfile:     /usr/local/redis/var/redis.pid
　　# Check that networking is up.

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
