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

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.
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.
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 sudo nano /etc/redis/redis.conf find and uncomment line # requirepass foobared, then restart server
now you password is foobared
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 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.
open redis configuration file
sudo nano /etc/redis/redis.conf set passphrase
replace
# requirepass foobared with
requirepass YOURPASSPHRASE restart redis
redis-server restart stop redis server using below command
/etc/init.d/redis-server stopenter command:
sudo nano /etc/redis/redis.conffind requirepass foobared word and remove # and change foobared to YOUR PASSWORD
ex. requirepass root
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.

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 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.
How to set redis password ?
step 1. stop redis server using below command /etc/init.d/redis-server stop
step 2.enter command : sudo nano /etc/redis/redis.conf
step 3.find # requirepass foobared word and remove # and change foobared to YOUR PASSWORD
ex. requirepass root
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 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.
