Create redis configuration file

Official website download configuration file

If:raw.githubusercontent.com cannot access the hosts file, you can modify it

Create the directory structure as follows:

Download the file from the official website and write it into the redis configuration file. Use the cat command to view the file content:

Modify configuration file

Description of some configuration parameters:

bind 127.0.0.1 #redis binding ip
protected-mode no #default yes, turn on protected mode, restrict local access
daemonize no #Default no
databases 16 #Number of databases (optional)
requirepass 123 #Password
dir /data/ #Enter the local redis database storage folder (optional)
appendonly yes #redis persistence default no (optional)

Set up redis to start when docker starts

docker update redis --restart=always

View auto-start status

 docker inspect redis --format='{<!-- -->{json .HostConfig.RestartPolicy}}'

Enter redis

docker exec -it redis /bin/bash

Connect redis

redis-cli -a 123456

Command format:

redis-cli [OPTIONS] [cmd [arg [arg ...]]] 

-h Server hostname (default: 127.0.0.1). ip address
-p Server port (default: 6379). Server port number
-s Server socket (overrides hostname and port).
-a Password to use when connecting to the server. Password
-u Server URI. Address in url format
-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. Specify the database
-x Read last argument from STDIN.
-d Multi-bulk delimiter in for raw formatting (default: \\
).
-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, …statistics continuous output
–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. Delay statistics
–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. Export rdb file
–pipe Transfer raw Redis protocol from stdin to server.
Pipeline mode
–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.
Pipe timeout
–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. Get all the keys of the server
–pattern Useful with –scan to specify a SCAN pattern.
Regular expression used in scan command
–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.
