ACL SETUSER username [rule [rule ...]]

Create an ACL user with the specified rules or modify the rules of an existing user. This is the main interface in order to manipulate Redis ACL users interactively: if the username does not exist, the command creates the username without any privilege, then reads from left to right all the rules provided as successive arguments, setting the user ACL rules as specified.

If the user already exists, the provided ACL rules are simply applied in addition to the rules already set. For example:

ACL SETUSER virginia on allkeys +set

The above command will create a user called virginia that is active (the on rule), can access any key (allkeys rule), and can call the set command (+set rule). Then another SETUSER call can modify the user rules:

ACL SETUSER virginia +get

The above rule will not apply the new rule to the user virginia, so other than SET, the user virginia will now be able to also use the GET command.

When we want to be sure to define an user from scratch, without caring if it had previously defined rules associated, we can use the special rule reset as first rule, in order to flush all the other existing rules:

ACL SETUSER antirez reset [... other rules ...]

After resetting an user, it returns back to the status it has when it was just created: non active (off rule), can't execute any command, can't access any key:

> ACL SETUSER antirez reset
1) "user antirez off -@all"

ACL rules are either words like "on", "off", "reset", "allkeys", or are special rules that start with a special character, and are followed by another string (without any space in between), like "+SET".

The following documentation is a reference manual about the capabilities of this command, however our ACL tutorial may be a more gentle introduction to how the ACL system works in general.

*List of rules

This is a list of all the supported Redis ACL rules:

  • on: set the user as active, it will be possible to authenticate as this user using AUTH <username> <password>.
  • off: set user as not active, it will be impossible to log as this user. Please note that if a user gets disabled (set to off) after there are connections already authenticated with such a user, the connections will continue to work as expected. To also kill the old connections you can use CLIENT KILL with the user option. An alternative is to delete the user with ACL DELUSER, that will result in all the connections authenticated as the deleted user to be disconnected.
  • ~<pattern>: add the specified key pattern (glob style pattern, like in the KEYS command), to the list of key patterns accessible by the user. You can add as many key patterns you want to the same user. Example: ~objects:*
  • allkeys: alias for ~*, it allows the user to access all the keys.
  • resetkey: removes all the key patterns from the list of key patterns the user can access.
  • +<command>: add this command to the list of the commands the user can call. Example: +zadd.
  • +@<category>: add all the commands in the specified category to the list of commands the user is able to execute. Example: +@string (adds all the string commands). For a list of categories check the ACL CAT command.
  • +<command>|<subcommand>: add the specified command to the list of the commands the user can execute, but only for the specified subcommand. Example: +config|get. Generates an error if the specified command is already allowed in its full version for the specified user. Note: there is no symmetrical command to remove subcommands, you need to remove the whole command and re-add the subcommands you want to allow. This is much safer than removing subcommands, in the future Redis may add new dangerous subcommands, so configuring by subtraction is not good.
  • allcommands: alias of +@all. Adds all the commands there are in the server, including future commands loaded via module, to be executed by this user.
  • -<command>. Like +<command> but removes the command instead of adding it.
  • -@<category>: Like +@<category> but removes all the commands in the category instead of adding them.
  • nocommands: alias for -@all. Removes all the commands, the user will no longer be able to execute anything.
  • nopass: the user is set as a "no password" user. It means that it will be possible to authenticate as such user with any password. By default, the default special user is set as "nopass". The nopass rule will also reset all the configured passwords for the user.
  • >password: Add the specified clear text password as an hashed password in the list of the users passwords. Every user can have many active passwords, so that password rotation will be simpler. The specified password is not stored as clear text inside the server. Example: >mypassword.
  • #<hashedpassword>: Add the specified hashed password to the list of user passwords. A Redis hashed password is hashed with SHA256 and translated into a hexadecimal string. Example: #c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2.
  • <password: Like >password but removes the password instead of adding it.
  • !<hashedpassword>: Like #<hashedpassword> but removes the password instead of adding it.
  • reset: Remove any capability from the user. It is set to off, without passwords, unable to execute any command, unable to access any key.


字符串: OK on success.

If the rules contain errors, the error is returned.
