redis: set a 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 2

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

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.
