6,启动测试：

# /opt/redis# nohup src/redis-server redis.conf &

# ps-ef|grep redis

# /usr/local/redis/bin/redis-cli ping

7,测试：

主服务103上执行创建：

# /usr/local/redis/bin/redis-cli -h 172.16.15.103 -a 1qaz@WSX 

    >set test 123456

从服务104上执行查看：

# /usr/local/redis/bin/redis-cli -h 172.16.15.104

    >get test

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 -p 6379 save

redis 资源信息数据统计查看： info

# redis-cli -h 127.0.0.1 -a passwd

    > info 

Redis 模糊搜索

 keys *

 select 2 

删除所有以user开头的key 可以这样实现：

# redis-cli keys "user*"

1) "user1"

2) "user2"

# redis-cli keys "user*" | xargs redis-cli del

(integer) 2

# 删除成功

# 批量删除匹配通配符的key用到了Linux中的管道和xargs参数：

redis-cli keys "s*" | xargs redis-cli del 

# 如果需要制定数据库，需要用到 -n 数据库编号   参数，下面是删除2数据库中s开头的键：

redis-cli -n 2 keys "s*" | xargs redis-cli -n 2 del

redis-cli keys "*" | xargs redis-cli del  

# 如果redis-cli没有设置成系统变量，需要指定redis-cli的完整路径  

＃　如：/opt/redis/redis-cli keys "*" | xargs /opt/redis/redis-cli del 

# 删除当前数据库中的所有Key  

flushdb  

# 删除所有数据库中的key  

flushall
