How to set password for Redis?

Question

I'm working with redis on my local machine so I dont really need to set up a password to connect to the server with my php client (I'm using predis as a client). However, I'm moving my app to a live server, so I want to set up a password to connect to my redis server.

I have few questions:

• I checked all over the internet about how to set up the password and it looks like I need to add the password in the redis.conf. I couldnt find though what I should add exactly to the configuration file to set up the password.

• also in predis how should I add the password. I'm using the following array of parameters to connect to the redis server

  $my_server = array('host' => '127.0.0.1','port' => 6379,'database' => 1);
  

should I add the password this way?

> $my_server = array('host'     => '127.0.0.1','port'     =>
> 6379,'database' => 1,'password'=>password);

• last question, I'm trying to stop my redis-server on the live server. Every time I enter the following command , I keep getting the same error message

  redis-server stop
  

  [23925] 23 Sep 20:23:03 # Fatal error, can't open config file 'stop'

  usually on my local machine I enter

  /etc/init.d/redis-server stop

to stop redis server but its not working on my live server since there is no process called redis-server in my /etc/init.d

Answer 1

To set the password, edit your redis.conf file, find this line

# requirepass foobared

Then uncomment it and change foobared to your password. Make sure you choose something pretty long, 32 characters or so would probably be good, it's easy for an outside user to guess upwards of 150k passwords a second, as the notes in the config file mention.

To authenticate with your new password using predis, the syntax you have shown is correct. Just add password as one of the connection parameters.

To shut down redis... check in your config file for the pidfile setting, it will probably be

pidfile /var/run/redis.pid

From the command line, run:

cat /var/run/redis.pid

That will give you the process id of the running server, then just kill the process using that pid:

kill 3832

Update

I also wanted to add, you could also make the /etc/init.d/redis-server stop you're used to work on your live server. All those files in /etc/init.d/ are just shell scripts, take the redis-server script off your local server, and copy it to the live server in the same location, and then just look what it does with vi or whatever you like to use, you may need to modify some paths and such, but it should be pretty simple.

This does not seem to work on Windows. I tried both conf files. I tried Redis restart in many combinations. The only thing that worked was: "redis-cli config set requirepass somepass". Additionally, every time server was restarted/shutdown, it was loosing password. So I guess, that's that with windows. – Florist

Depending on the chosen installation process we can have the Redis configuration file as "vi /etc/redis/redis.conf" or "vi /etc/redis/6379.conf" (eg) where "6379" is the value chosen for the port! – Disinherit

Is there a maximum password length? – Unchurch

Also, if the redis server is running, it prints out the pid at the top upon start... it should say Redis version=x.x.x bits=64, commit=xxxxxx, modified=0, pid=xxxx – Wingspan

Redis got better, machines become faster. Redis 6's config file states that "since Redis is pretty fast an outside user can try up to 1 million passwords per second against a modern box". It was 150K :-) I personally was using something like this openssl rand 50 | openssl base64 -A to generate a long password. However perhaps it is better to use ACL now. – Vet

@Florist redis.windows-service.conf is the config file you need to put your password in just like redis.windows.conf if you are running it as a service to keep authentication after redis restart – Steakhouse

yeah just uncommenting that then restarting redis worked for me – Paleobiology

Answer 2

you can also use following command on client

cmd :: config set requirepass p@ss$12E45

above command will set p@ss$12E45 as a redis server password.

Just to add: As mentioned at tutorialspoint.com/redis/redis_security.htm to login via redis-cli first get into the redis shell by running redis-cli.exe. Then type AUTH <password>. – Corpse

And to disable password authentication, simply use config set requirepass "" – Corpse

And it will reset to old if you restart redis. So, add in conf file as well. – Hydrophilic

Config set requirepass "myPassword" this command is not working for me, when I execute this command then it runs with no error. Then I restarted my Redis instance. But I can still ping to Redis instance from CLI without proving any password. Later I checked my redis.conf for requirepass attribute, there I found it in default state, which means config set requirepass command failed to set the value of requirepass in my config that's the reason it was not working. Any guess/reason why it is not working? – Galligaskins

but you have to issue this after every server upstart. otherwise it wont bite, right? thats what I am getting. – Snaggletooth

Answer 3

Example:

redis 127.0.0.1:6379> AUTH PASSWORD
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> CONFIG SET requirepass "mypass"
OK
redis 127.0.0.1:6379> AUTH mypass
Ok

If one is using redis-py, the associated command is: redis.Redis.config_set('requirepass', "mycoolpassword") – Merete

Config set requirepass "myPassword" this command is not working for me, when I execute this command then it runs with no error. Then I restarted my Redis instance. But I can still ping to Redis instance from CLI without proving any password. Later I checked my redis.conf for requirepass attribute, there I found it in default state, which means config set requirepass command failed to set the value of requirepass in my config that's the reason it was not working. Any guess/reason why it is not working? – Galligaskins

@AshishShukla how did you restart your Redis instance? – Obstructionist

@LeaReimann in Linux you can use command -> sudo systemctl restart redis – Galligaskins

this command won't work if you restart redis! – Abri

Answer 4

using redis-cli:

root@server:~# redis-cli 
127.0.0.1:6379> CONFIG SET requirepass secret_password
OK

this will set password temporarily (until redis or server restart)

test password:

root@server:~# redis-cli 
127.0.0.1:6379> AUTH secret_password
OK

Answer 5

sudo nano /etc/redis/redis.conf 

find and uncomment line # requirepass foobared, then restart server

now you password is foobared

Answer 6

For those who use docker-compose, it’s really easy to set a password without any config file like redis.conf. Here’s how you would normally use the official Redis image:

redis:
    image: 'redis:4-alpine'
    ports:
      - '6379:6379'

And here’s all you need to change to set a custom password:

  redis:
    image: 'redis:4-alpine'
    command: redis-server --requirepass yourpassword
    ports:
      - '6379:6379'

Everything will start up as normal and your Redis server will be protected by a password.

For details, this blog post seems to support the idea.

How does this know what user to use when other services wants to connect to Redis? Would it take the default or can you specify this on the commandline aswell? – Eng

Password for the “default” user is set in the configuration named “requirepass“ – Istic

Answer 7

open redis configuration file

sudo nano /etc/redis/redis.conf 

set passphrase

replace

# requirepass foobared

with

requirepass YOURPASSPHRASE

restart redis

redis-server restart

If you are using redis as a service on Windows then you need to set password in redis.windows-service.conf file as well. – Steakhouse

Answer 8

1. stop redis server using below command

   /etc/init.d/redis-server stop
   

2. enter command: sudo nano /etc/redis/redis.conf

3. find requirepass foobared word and remove # and change foobared to YOUR PASSWORD

ex. requirepass root

Comintern

Answer 9

On versions prior to REDIS 6 , the only way to secure your REDIS is to open your redis.conf , uncomment the # requirepass line, and add in your password. However , the downside of this is that this is a global password shared by ALL connections.

requirepass iampwd

Unless you need backwards compatibility you should move to REDIS 6, and instead use ACLs to create users with the least privileges

acl setuser dummyuser on >dummypwd allcommands allkeys

For Mac installed with HomeBrew/Brew (redis-cli):

redis-cli
AUTH oldpassword
CONFIG SET requirepass "newpassword"
CONFIG REWRITE

Restart:

brew services stop redis
//relogin

Answer 11

For that, you need to update the redis configuration file.By default, there is no any password for redis.

01) open redis configuration file

sudo vi /etc/redis/redis.conf

find requirepass field under SECURITY section and uncomment that field.Then set your password instead of "foobared"

# requirepass foobared

It should be like,

requirepass YOUR_PASSWORD

Then restart redis and start redis-cli.

If you need to check whether you have set the password correctly, you can run below commads in redis-cli.

sithara@sithara-X555UJ ~ $ redis-cli
127.0.0.1:6379> set key1 18
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth admin
OK
127.0.0.1:6379> get key1
(nil)
127.0.0.1:6379> exit


sithara@sithara-X555UJ ~ $ redis-cli
127.0.0.1:6379> set key1 18
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth admin
OK
127.0.0.1:6379> set key2 check
OK
127.0.0.1:6379> get key2
"check"
127.0.0.1:6379> get key1
(nil)
127.0.0.1:6379> set key1 20
OK
127.0.0.1:6379> get key1
"20"
127.0.0.1:6379> exit

Answer 12

This error means there is no password set in your redis instance. If you send auth information from your code you will probably get this message. There are two ways to solve.

1. Open the redis config file.

   sudo nano /etc/redis/redis.conf
   

   You can use 'where is' option to find '# requirepass'

   Uncomment the passphrase line and set new password

   # requirepass yourpassword
   

2. Open terminal and connect redis-cli

   redis-cli
   

3. Set passphrase

   CONFIG SET requirepass "yourpassword"
   
   

4. Finally, you can test

   AUTH yourpassword
   

Thats is!

Answer 13

i couldnt find though what i should add exactly to the configuration file to set up the password.

Configuration file should be located at /etc/redis/redis.conf and password can be set up in SECURITY section which should be located between REPLICATION and LIMITS section. Password setup is done using the requirepass directive. For more information try to look at AUTH command description.

Answer 14

Run Command

redis-cli


redis 127.0.0.1:6379> AUTH PASSWORD
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> CONFIG SET requirepass "amolpass"
OK
redis 127.0.0.1:6379> AUTH amolpass    
Ok

------------------OR ----------------------

Get Redis Installation Path

redis-cli config get dir

GET Config File Path

sudo find / -name "redis.conf" -exec grep -H "^dir" {} \; 2> /dev/null

generate the same password as this one:

echo "amol-pass" | sha1sum OUTPUT :960c3dac4fa81b4204779fd16ad7c954f95942876b9c4fb1a255667a9dbe389d

Edit : /etc/redis/redis.conf
requirepass 960c3dac4fa81b4204779fd16ad7c954f95942876b9c4fb1a255667a9dbe389d

Restart Redis

 service redis-server restart

 TEST Command : 
 redis-cli 
 set key1 10
 (error) NOAUTH Authentication required.
 auth your_redis_password

Answer 16

If you are losing password on Redis restart and you are running Redis as a windows service then you should set requirepass in redis.windows-service.conf file as well.

Answer 17

In Linux Machine

First Check Redis Status using the below command

sudo systemctl status redis

Now open the below file

sudo nano /etc/redis/redis.conf

In the Security Section, you can easily find the

#requirepass foobared

Change that to whatever password you wanted to save for redis connection

requirepass your_password or requirepass foobared

Now your file section content looks like

Press Control + C, Control + Y & ENTER. The file will be saved now.

Now Restart the REDIS DB using the below Linux command

sudo systemctl restart redis

Now REDIS Password is SET SUCCESSFULLY 😊.
