redis的安装

1.安装

$ wget http://download.redis.io/releases/redis-2.8.9.tar.gz
$ tar xzf redis-2.8.9.tar.gz
$ cd redis-2.8.9
$ make

make之后，会出现一句提示：
Hint: To run 'make test' is a good idea ;)
其实不测试，一般都可以用。但是既然人家建议了，咱们就走一下make test吧。
运行

#make test

成功以后，提示：

\o/ All tests passed without errors!

Cleanup: may take some time... OK
make[1]: Leaving directory `/root/redis-2.8.9/src'

执行完后，会在当前目录中的src目录中生成相应的执行文件，如：redis-server redis-cli等；

2.精简运行文件

mkdir /usr/local/redis/{conf,bin,db} -pv
cp redis.conf /usr/local/redis/conf
cd src
cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server mkreleasehdr.sh /usr/local/redis/bin/

3.启动redis

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

[26765] 10 May 23:52:10.708 # Server started, Redis version 2.8.9
[26765] 10 May 23:52:10.708 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
[26765] 10 May 23:52:10.708 * The server is now ready to accept connections on port 6379

此时启动所有的配置都是默认的，可以看到redis是前台运行，启动服务默认端口6379

4.查询运行

# netstat -tlnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name   
tcp        0      0 0.0.0.0:6379                0.0.0.0:*                   LISTEN      26765/redis-server 

5.客户端连接

# ./redis-cli 
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
"bar"
127.0.0.1:6379> 

6.关闭redis

redis-cli shutdown

也可以指定端口:

redis-cli -p 6380 shutdown
