redis安装

1、需要下载redis：http://download.redis.io/releases/，选主自己需要的版本下载即可。

2、传至对应服务器上，解压，编译。

tar -xf redis-4.0.2.tar.gz
cd redis-4.0.2/
make

3、启动，即可

src/redis-server

4、客户端验证

$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"

 

遇见问题

1、远端无法连接，异常信息如下：

Exception in thread "main" redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the 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‘ from 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 permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to ‘no‘, and then restarting the server. 3) If you started the server manually just for testing, restart it with the ‘--protected-mode no‘ option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

解决办法：

在redis.conf文件中
1、将bind 127.0.0.1配置信息改为自己对应服务器地址。
2、protected-mode yes参数修改为no
最后，在重启redis-server时，指定配置文件，如下命令，这样就可以通过本地连接远端的redis
./redis-server ../redis.conf
