# make PREFIX=/usr/local/redis-3.2.0 install

单独安装hiredis

$ tar -zxvf hiredis-1.0.0.tar.gz

$ make

$ make PREFIX=/usr/local/hiredis-1.0.0 install

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

>telnet 192.168.0.102 6379

 

配置文件

 

可以从源代码程序中拷贝一份配置文件模板：

# cp /home/root/packages/redis-3.2.0/redis.conf /usr/local/redis-3.2.0/redis-default.conf

# cp /home/root/packages/redis-3.2.0/sentinel.conf /usr/local/redis-3.2.0/sentinel-default.conf

 

-DENIED Redis is running in protected mode because protected mode is e

nabled, no bind address was specified, no authentication password is r

equested to clients. In this mode connections are only accepted from t

he loopback interface. If you want to connect from external computers

to Redis you may adopt one of the following solutions: 1) Just disable

 protected mode sending the command 'CONFIG SET protected-mode no' fro

m the loopback interface by connecting to Redis from the same host the

 server is running, however MAKE SURE Redis is not publicly accessible

 from internet if you do so. Use CONFIG REWRITE to make this change pe

rmanent. 2) Alternatively you can just disable the protected mode by e

diting the Redis configuration file, and setting the protected mode op

tion to 'no', and then restarting the server. 3) If you started the se

rver manually just for testing, restart it with the '--protected-mode

no' option. 4) Setup a bind address or an authentication password. NOT

E: You only need to do one of the above things in order for the server

 to start accepting connections from the outside.
