how to check redis-instance version?

I've found in Redis site this command:

$ redis-server

and that should give me (according to the site):

[28550] 01 Aug 19:29:28 # Warning: no config file specified, using the default config. In order to specify a config file use 'redis-server /path/to/redis.conf'
[28550] 01 Aug 19:29:28 * Server started, Redis version 2.2.12
[28550] 01 Aug 19:29:28 * The server is now ready to accept connections on port 6379
... and so forth ...

but I get this instead:

[8719] 04 Feb 14:51:09.009 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
[8719] 04 Feb 14:51:09.009 # Unable to set the max number of files limit to 10032 (Operation not permitted), setting the max clients configuration to 3984.
[8719] 04 Feb 14:51:09.009 # Creating Server TCP listening socket *:6379: bind: Address already in use

which mean I need to configure it, but all I want is the version!

so how do I check redis instance version?

回答1:

$ redis-server --version

gives you the version.

回答2:

Run the command INFO. The version will be the first item displayed.

The advantage of this over redis-server --version is that sometimes you don't have access to the server (e.g. when it's provided to you on the cloud), in which case INFO is your only option.

if you want to know a remote redis server's version, just connect to that server and issue command "info server", you will get things like this:

...
redis_version:3.2.12
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:9c3b73db5f7822b7
redis_mode:standalone
os:Linux 2.6.32.43-tlinux-1.0.26-default x86_64
arch_bits:64
multiplexing_api:epoll
gcc_version:4.9.4
process_id:5034
run_id:a45b2ffdc31d7f40a1652c235582d5d277eb5eec

There are two commands, which you can use to check the version of redis

    redis-server -v

or

    redis-server --version
