1.redis-cli使用時各引數的含義和使用方法

[email protected]:~/7000$ redis-cli  --help
redis-cli 3.0.3

Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]
  -h <hostname>      Server hostname (default: 127.0.0.1).
  -p <port>          Server port (default: 6379).
  -s <socket>        Server socket (overrides hostname and
 
 port).
  -a <password>      Password to use when connecting to the server.
  -r <repeat>        Execute specified command N times.
  -i <interval>      When -r is used, waits <interval> seconds per command.
                     It is possible to specify sub-second times like -i 0.1
 
.
  -n <db>            Database number.
  -x                 Read last argument from STDIN.
  -d <delimiter>     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, ...
  --latency          Enter a special mode continuously sampling latency.
  --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 <keys>  Simulate a cache workload with an 80-20 distribution.
  --slave            Simulate a slave showing commands received from the master.
  --rdb <filename>   Transfer an RDB dump from remote server to local file.
  --pipe             Transfer raw Redis protocol from stdin to server.
  --pipe-timeout <n> In --pipe mode, abort with error if after sending all data.
                     no reply is received within <n> seconds.
                     Default timeout: 30. Use 0 to wait forever.
  --bigkeys          Sample Redis keys looking for big keys.
  --scan             List all keys using the SCAN command.
  --pattern <pat>    Useful with --scan to specify a SCAN pattern.
  --intrinsic-latency <sec> Run a test to measure intrinsic system latency.
                     The test will run for the specified amount of seconds.
  --eval <file>      Send an EVAL command using the Lua script at <file>.
  --help             Output this help and exit.
  --version          Output version and exit.

Examples:
  cat /etc/passwd | redis-cli -x set mypasswd
  redis-cli get mypasswd
  redis-cli -r 100 lpush mylist x
  redis-cli -r 100 -i 1 info | grep used_memory_human:
  redis-cli --eval myscript.lua key1 key2 , arg1 arg2 arg3
  redis-cli --scan --pattern '*:12345*'

  (Note: when using --eval the comma separates KEYS[] from ARGV[] items)

When no command is given, redis-cli starts in interactive mode.
Type "help" in interactive mode for information on available commands.

redis cluster命令列

//叢集(cluster)  
CLUSTER INFO 列印叢集的資訊  
CLUSTER NODES 列出叢集當前已知的所有節點（node），以及這些節點的相關資訊。   

//節點(node)  
CLUSTER MEET <ip> <port> 將 ip 和 port 所指定的節點新增到叢集當中，讓它成為叢集的一份子。  
CLUSTER FORGET <node_id> 從叢集中移除 node_id 指定的節點。  
CLUSTER REPLICATE <node_id> 將當前節點設定為 node_id 指定的節點的從節點。

//槽(slot)  
CLUSTER ADDSLOTS <slot> [slot ...] 將一個或多個槽（slot）指派（assign）給當前節點。  
CLUSTER DELSLOTS <slot> [slot ...] 移除一個或多個槽對當前節點的指派。  
CLUSTER FLUSHSLOTS 移除指派給當前節點的所有槽，讓當前節點變成一個沒有指派任何槽的節點。 
CLUSTER SETSLOT <slot> NODE <node_id> 將槽 slot 指派給 node_id 指定的節點，如果槽已經指派給另一個節點，那麼先讓另一個節點刪除該槽>，然後再進行指派。  
CLUSTER SETSLOT <slot> MIGRATING <node_id> 將本節點的槽 slot 遷移到 node_id 指定的節點中。  
CLUSTER SETSLOT <slot> IMPORTING <node_id> 從 node_id 指定的節點中匯入槽 slot 到本節點。  
CLUSTER SETSLOT <slot> STABLE 取消對槽 slot 的匯入（import）或者遷移（migrate）。   

//鍵 (key)  
CLUSTER KEYSLOT <key> 計算鍵 key 應該被放置在哪個槽上。  
CLUSTER COUNTKEYSINSLOT <slot> 返回槽 slot 目前包含的鍵值對數量。  
CLUSTER GETKEYSINSLOT <slot> <count> 返回 count 個 slot 槽中的鍵。  
這些命令是叢集所獨有的。執行上述命令要先登入
