Dynomite - Redis session for PHP
Hello, I am trying to use dynomite to geo replicate redis sessions.
These are the versions I am using :
[root@cmd-redis1 ~]# redis-cli --version
redis-cli 5.0.1
[root@cmd-redis1 ~]# dynomite --version
This is dynomite-v0.7.0-9-gaec7c38
[root@cmd-redis1 ~]# redis-server --version
Redis server v=5.0.1 sha=00000000:0 malloc=jemalloc-5.1.0 bits=64 build=cf1c54ca8dfae683
I have 6 nodes, 3 racks and 3 datacenters.
Here is the config I have for one node :
dyn_o_mite:
datacenter: dc-nyh
rack: rack1
dyn_listen: 10.151.2.125:7379
dyn_seeds:
- 10.151.2.126:7380:rack1:dc-nyh:2147483647
- 10.150.20.125:7379:rack1:dc-dfw:0
- 10.150.20.126:7380:rack1:dc-dfw:2147483647
- 10.160.65.125:7379:rack1:dc-lon:0
- 10.160.65.126:7380:rack1:dc-lon:2147483647
listen: 0.0.0.0:8379
servers:
- 10.151.2.125:6379:1
tokens: '0'
secure_server_option: datacenter
pem_key_file: dynomite.pem
data_store: 0
stats_listen: 127.0.0.1:22222
read_consistency : DC_QUORUM
write_consistency : DC_QUORUM
In my php.ini I have
session.save_handler = redis
;session.save_handler = memcache
session.save_path = "tcp://10.151.2.125:8379,tcp://10.151.2.126:8379"
So in each webserver per DC I am pointing the local dynomite servers.
If I try to login to my I see this in the logs :

In PHP I have the redis pecl extension installed. PHP v 7.2.14
I don't see COMMAND as compatible with dynomite : https://github.com/Netflix/dynomite/blob/dev/notes/redis.md
I tried then to change redis-cli to 3.0.7 and I am not getting the error about COMMAND but I see this in the error_log on apache :
[Fri Apr 05 12:10:21.956763 2019] [php7:notice] [pid 150544:tid 140261963302656] [client 10.222.90.33:54926] PHP WARNING: session_regenerate_id(): Session object destruction failed. ID: redis (path: tcp://10.151.2.125:8379,tcp://10.151.2.126:8379) in /data/www/cmd/pages/login.page on line 188, referer: http://nyh-cmd2.stag.gt-t.net/
If I downgrade redis-server as well the error is :
[Fri Apr 05 13:18:12.043633 2019] [php7:notice] [pid 179837:tid 139654653261568] [client 10.222.90.33:56536] PHP WARNING: Unknown: Failed to write session data (redis). Please verify that the current setting of session.save_path is correct (tcp://10.151.2.125:8379) in Unknown on line 0, referer: http://nyh-cmd2.stag.gt-t.net/?!=intranet|home|view
Can anyone help me to understand what to set in the php.ini? Is there a workaround?
Thanks
Correct, the log message parsed unsupported command 'COMMAND' indicates that Dynomite does not support this command.
Moreover, the problem above seems to be a mismatch of the port numbers. I think you are trying to access 8379 but you have set the dyn_listen as 7379.
No i tried with both ports and it does not work. I guess it is just not compatible with redis 5 and php

We use PHP 7 and Redis 3.2 OK, but only specify a single node on save_path. Does that work for you?
Nope, also with a single node, it does not work.
