Redis客户端redis-cli命令详解

使用方法：

打开CMD窗口，切换到Redis安装目录后，输入以下命令启动Redis客户端

 redis-cli  -h 127.0.0.1 -p 6379

命令参数说明：

  -h       Server hostname (default: 127.0.0.1). Redis服务IP
  -p           Server port (default: 6379).　Redis服务端口
  -s         Server socket (overrides hostname and port).
  -a       Password to use when connecting to the server.　密码
  -u            Server URI.　url格式的地址
  -r         Execute specified command N times.
  -i       When -r is used, waits  seconds per command.
                     It is possible to specify sub-second times like -i 0.1.
  -n             Database number.　指定数据库
  -x                 Read last argument from STDIN.
  -d      Multi-bulk delimiter in for raw formatting (default: \n).
  -c                 Enable cluster mode (follow -ASK and -MOVED redirections).
  --raw              Use raw formatting for replies (default when STDOUT is
                     not a tty).
  --no-raw           Force formatted output even when STDOUT is not a tty.
  --csv              Output in CSV format.
  --stat             Print rolling stats about server: mem, clients, ...　统计数据，连续输出
  --latency          Enter a special mode continuously sampling latency.
                     If you use this mode in an interactive session it runs
                     forever displaying real-time stats. Otherwise if --raw or
                     --csv is specified, or if you redirect the output to a non
                     TTY, it samples the latency for 1 second (you can use
                     -i to change the interval), then produces a single output
                     and exits.　延时统计
  --latency-history  Like --latency but tracking latency changes over time.
                     Default time interval is 15 sec. Change it using -i.
  --latency-dist     Shows latency as a spectrum, requires xterm 256 colors.
                     Default time interval is 1 sec. Change it using -i.
  --lru-test   Simulate a cache workload with an 80-20 distribution.
  --replica          Simulate a replica showing commands received from the master.
  --rdb    Transfer an RDB dump from remote server to local file. 导出rdb文件
  --pipe             Transfer raw Redis protocol from stdin to server.
  管道模式
  --pipe-timeout  In --pipe mode, abort with error if after sending all data.
                     no reply is received within  seconds.
                     Default timeout: 30. Use 0 to wait forever.
                     管道超时
  --bigkeys          Sample Redis keys looking for big keys.
  --hotkeys          Sample Redis keys looking for hot keys.
                     only works when maxmemory-policy is *lfu.
  --scan             List all keys using the SCAN command.获取服务器所有的键
  --pattern     Useful with --scan to specify a SCAN pattern.
  正则表达式　用于scan命令中
  --intrinsic-latency  Run a test to measure intrinsic system latency.
                     The test will run for the specified amount of seconds.
  --eval       Send an EVAL command using the Lua script at .
  --ldb              Used with --eval enable the Redis Lua debugger.
  --ldb-sync-mode    Like --ldb but uses the synchronous Lua debugger, in
                     this mode the server is blocked and script changes are
                     not rolled back from the server memory.
  --cluster  [args...] [opts...]
                     Cluster Manager command and arguments (see below).
  --verbose          Verbose mode.
  --no-auth-warning  Don't show warning message when using password on command
                     line interface.
