QUESTION
I have a web application running on Laravel5.2 framework, with session driver set to redis with following AWS setup.
Instance-1: Running web application, with Redis configurations in .env file as follow
- Redis-host:
aws-private-ip-of-instance-2
- Redis-password:
NULL
- Redis-port:
6379
- Redis-host:
Instance-2: Redis-server running with following configuration
- Bind
aws-private-ip-of-instance-2
and 127.0.0.1 - Working directory
/var/lib/redis
with 775 permission, and ower-group is redis. - RDB snapshot name
dump.rdb
with 660 permission, and ower-group is redis.
- Bind
NOTE: In AWS inbound rule for port
6379
is configured for Instance-2.
Everything works fine, until redis tries to write the data on the RDB file. Following error shows on front-end.
MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.
While in the logs of Redis server i got following data.
...ANSWER
Answered 2019-Oct-04 at 19:47This other Stack Exchange thread might help, since you are using a custom /tmp dir for data:
The simple way to do this is to run
systemctl edit redis
. This will create an override drop-in file/etc/systemd/system/redis.service.d/override.conf
, in which you can place your changes (and the proper section):
[Service]
ReadWriteDirectories=-/my/custom/data/dir
You may also create that directory and place files ending in
.conf
in it manually. But do not leave the directory empty, as this will disable the service.In either case, run
systemctl daemon-reload
and you are ready to restart your service.
Many threads also point to filesystem inconsistency as root cause. Since you are using EC2, check this AWS forums post:
To fix this, you will have to:
Stop the instance
Detach the root volume of your instance
Attach the volume as a data volume to any running Linux instance in the same availability zone
Perform a filesystem check (fsck) on the volume and fix the issues
Detach the volume and attach it back to your instance as it's root volume
Boot back instance and verify if the volume was able to mount successfully
As a last resort, terminate the instance if possible.
Hope it helps!

Install redis-admin
You can use redis-admin like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
