[php] How to set password for Redis?

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' => '','port' => 6379,'database' => 1);

should I add the password this way?

> $my_server = array('host'     => '','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

This question is related to php redis

The answer is

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


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.
