2. 查看Redis客户端命令帮助
[root@node1 ~]# /usr/local/redis/bin/redis-cli --help
redis-cli 4.0.9
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.
-u <uri> Server URI.
-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 infor raw formatting (default: \n).
-c Enable cluster mode (follow -ASK and -MOVED redirections).
--raw Use raw formatting for replies (defaultwhen STDOUT isnot a tty).
--no-raw Force formatted output even when STDOUT isnot a tty.
--csv Output in CSV format.
--stat Print rolling stats about server: mem, clients, ...
--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, orif you redirect the output to a non
TTY, it samples the latency for1 second (you can use
-i to change the interval), then produces a single output
and exits.
--latency-history Like --latency but tracking latency changes over time.
Default time interval is15 sec. Change it using -i.
--latency-dist Shows latency as a spectrum, requires xterm 256 colors.
Default time interval is1 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 witherrorif after sending all data.
no reply is received within <n> seconds.
Default timeout: 30. Use 0to wait forever.
--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.
--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>.
--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
are not rolled back from the server memory.
--help Output this help andexit.
--version Output version andexit.
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: whenusing --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
and settings.
