|
A redis DB can be connected by an URL, in :py:obj:`searx.redisdb` you
|
|
will find a description to test your redis connection in SerXNG. 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)`_ & :ref:`redis db`::
|
|
|
|
redis://[[username]:[password]]@localhost:6379/0
|
|
rediss://[[username]:[password]]@localhost:6379/0
|
|
unix://[[username]:[password]]@/path/to/socket.sock?db=0
|
|
|
|
.. admonition:: Tip for developers
|
|
|
|
To set up a local redis instance, first set the socket path of the Redis DB
|
|
in your YAML setting:
|
|
|
|
.. code:: yaml
|
|
|
|
redis:
|
|
url: unix:///usr/local/searxng-redis/run/redis.sock?db=0
|
|
|
|
Then use the following commands to install the redis instance ::
|
|
|
|
$ ./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
