启动方式
前端模式
- /usr/local/Redis/bin/Redis-server
- 1
测试结果:
后端模式
- # 设置 daemonize 为 yes
- VIM /usr/local/Redis/Redis.conf
- # Redis-server 根据 Redis.conf 文件启动 Redis
- cd /usr/local/Redis/
- ./bin/Redis-server ./Redis.conf
- # 启动后查看 Redis 默认端口号为 6379
- ps -ef | grep -i Redis
- # 关闭 Redis
- ./bin/Redis-cli shutdown

执行 VIM /usr/local/Redis/Redis.conf 后, 在 Redis.conf 中 daemonize 设置为 yes
执行 ps -ef | grep -i Redis
Redis 使用
通过 Redis 客户端远端连接 Redis
- # 打开 6379 端口
- /sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
- /etc/rc.d/init.d/iptables save
- # 连接客户端
- ./bin/Redis-cli -h 192.168.182.137 -p 6379
- # 测试连接
- 192.168.182.137:6379> ping

执行./bin/Redis-cli -h 192.168.182.137 -p 6379 命令出现如下错误: Could not connect to Redis at 192.168.182.137:6379: Connection refused
解决方法: VIM Redis.conf, 找到 bind 选项注释之.
执行 ping 命令, 出现如下提示信息:
- (error) 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.

错误的原因是 Redis 出于保护模式, 远端连接失败. 此时有四种解决方法, 博主采用方案 2 解决 vi Redis.conf, 找到 protected-mode 选项设置为 no, 然后重启 Redis 即可.
最后远程连接之后使用 ping 命令得出如下结果:
Redis 图形化界面
在 Linux 下 Redis 的操作需要使用 Redis 客户端命令, 但是其显示还是较为麻烦. 通过在 Windows 下安装 Redis 图形化界面, 可以查看对应主机的 Redis 的内容. 博主安装的是 Redis-desktop-manager. 安装完成后, 根据主机名和地址连接对应的 Redis 即可.
通过点击 2 处的 Connect to Redis Server 打开连接界面, 输出对应的 Redis 所在的主机的 ip 地址和用户名即可登陆. 登陆结果可知, 默认 Redis 创建 16 个数据库.
