连接
连接到redis可以通过redis提供的redis-cli工具，还可以通过telnet的方式连接到redis。
通过redis-cli工具连接到redis
# redis-cli
127.0.0.1:6379> help
redis-cli 3.0.0
Type: "help @<group>" to get a list of commands in <group>
"help <command>" for help on <command>
"help <tab>" to get a list of possible help topics
"quit" to exit
# redis-cli -h 127.0.0.1 -p 6379
通过redis-cli工具还可以不进入命令行模式下直接执行命令：
# redis-cli get hello
"this is c"
# redis-cli set key1 value1
OK
# redis-cli get key1
"value1"
通过telnet的方式连接到redis
