# `redis:`

A redis DB can be connected by an URL, in `searx.redisdb` you will find a description to test your redis connection in SearXNG. When using sockets, don’t forget to check the access rights on the socket:

    ls -la /usr/local/searxng-redis/run/redis.sock
    srwxrwx--- 1 searxng-redis searxng-redis ... /usr/local/searxng-redis/run/redis.sock

In this example read/write access is given to the searxng-redis group. To get access rights to redis instance (the socket), your SearXNG (or even your developer) account needs to be added to the searxng-redis group.

`url``$SEARXNG_REDIS_URL`

  URL to connect redis database, see Redis.from_url(url) & Redis DB:

      redis://[[username]:[password]]@localhost:6379/0
      rediss://[[username]:[password]]@localhost:6379/0
      unix://[[username]:[password]]@/path/to/socket.sock?db=0

## Redis Developer Notes

To set up a local redis instance, first set the socket path of the Redis DB in your YAML setting:

    redis:
      url: unix:///usr/local/searxng-redis/run/redis.sock?db=0

Then use the following commands to install the redis instance (./manage redis.help):

    $ ./manage redis.build
    $ sudo -H ./manage redis.install
    $ sudo -H ./manage redis.addgrp "${USER}"
    # don't forget to logout & login to get member of group
