1.编译redis.conf参数文件
安装完成后，我们就得尝试启动redis服务了。
在$REDIS_HOME，编译如下文件
/home/ldh/redis/redis-2.8.3/redis.conf
修改端口
将PORT 6379改成你想要的被客户访问的端口，不改也可以，只要不冲突。
设置密码：
redis.conf中requirepass前的注释去掉，后面加上密码，如
requirepass pass1234
如果服务已经启动，修改密码后需要重启服务才能使新密码生效。
2.启动服务
启动服务，假如不用Nohup的话，当前会话就不能再进行其他操作咯。
nohup redis-server /home/ldh/redis/redis-2.8.3/redis.conf &
我们来看看nohup.out中，这个服务启动会反馈什么信息
[ldh@hauser redis-2.8.3]$ vi nohup.out

[22737] 25 Dec 11:06:25.931 * The server is now ready to accept connections on port 6389
此时，redis服务已经启动了。
3.登陆redis
此时我们登陆到redis数据库当中
[ldh@hauser redis-2.8.3]$ redis-cli -h 127.0.0.1 -p 6389 -a pass1234
127.0.0.1:6389> set fwy abc
OK
127.0.0.1:6389> get fwy
"abc"
本机登陆的话，也可以省略-h，如果是用默认端口6379，那么-p也可以省略。
如redis-cli -a pass1234登陆即可
如果远程登陆，可以用telnet登陆，退出时敲进quit
[fengweiyuan513@cnsz081003 ~]$ telnet 10.25.30.143 6389
Trying 10.25.30.143...
Connected to 10.25.30.143 (10.25.30.143).
Escape character is '^]'.
auth pass1234
+OK
get fwy
$1
2
quit
+OK
Connection closed by foreign host.
[fengweiyuan513@cnsz081003 ~]$
4.停止redis服务
[ldh@hauser ~]$ redis-cli -h 127.0.0.1 -p 6389 -a pass1234
127.0.0.1:6389> shutdown
127.0.0.1:6389> exit
再连接一次已经发现不存在了，也可以通过ps -ef | grep redis来观察
[ldh@hauser ~]$ redis-cli -p 6389 -a pass1234
Could not connect to Redis at 127.0.0.1:6389: Connection refused
远程通过telnet来shutdown也是可以的，感觉挺不安全的。
