Upgrading to 0.4.3 broke my forum

Does this mean anything? (from output.log)

node_redis: no callback to send error: ERR unknown command 'pexpire'

Also, the heart buttons on each post turned into blocks...I'm trying to decide whether to hack away at this or find another route -- like is there a way to just make the recent topics list the homepage, without using the custom homepage plugin?

node_redis: no callback to send error: ERR unknown command 'pexpire'

Looks like your Redis version isn't quite up to date... NodeBB requires a minimum of v2.6

@julian

Mayhaps @psychobunny could add "redis needs to be updated like so" that to the NodeBB for Dummies install guide? I just followed those instructions like a robot, and robots don't know what needs updating

Like now I'm trying to update redis and got this message when running the install script:

Starting Redis server...
*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 55
>>> 'tcp-backlog 511'
Bad directive or wrong number of arguments
ERROR: Failed starting service.... Aborting!

...and I still get this message when trying to log in to my forum using email+password, with the latest stable redis downloaded but not working apparently?

{"error":"Cannot read property '_csrf' of undefined"}

I just used the digitalocean guide to getting the newest redis, but changed the path to get the latest stable version. Is there any way to roll back to 0.4.2? My forum is all jacked up now!

sudo apt-get install -y python-software-properties
sudo add-apt-repository -y ppa:rwky/redis
sudo apt-get update
sudo apt-get install -y redis-server

@a_5mith

Thanks man! Redis is updated, but now the forum is wiped and I can't log in to ACP. Is there something else I needed to do?

julian

Forum wiped? That really doesn't seem right... what files do you see in /var/lib/redis? What are their sizes (use ls -lh to check)?

a_5mith

@zenkamal updating redis definitely shouldn't wipe anything, do you have a redis password set in your config? I'm not sure if updating redis resets redis.conf and wipes your redis password or not...

? Offline

@a_5mith

Nope, didn't set up a redis password.

The only thing I did is type in those four lines, check the version (successfully updated!) and then blammo the forum's gone now. I suppose I could revert to a backup or start all over, but I'd rather try to avoid that

These are the files:

drwxr-xr-x 2 root  root  4.0K May 26 01:24 6379
-rw-rw---- 1 redis redis 1.1M May 26 14:26 dump.rdb
drwxrwxr-x 6 root  root  4.0K Apr 22 04:14 redis-2.8.9
-rw-r--r-- 1 root  root  1.1M Apr 22 04:15 redis-2.8.9.tar.gz
-rw-rw---- 1 redis redis 131K May 26 15:44 redis.rdb

The forum doesn't have anything on it after the redis update, and my admin login doesn't work. I haven't done anything except follow the digitalocean install guide, set up reverse proxy in nginx.conf, and update redis.

julian

I think I know what happened...

old redis (< 2.4..?) had default database file as dump.rdb. Newer redis configs have the database file set to redis.rdb.

You should have a config file for redis at /etc/redis/redis.conf. Look for a line that starts with dbfilename. What is its value? It's probably redis.rdb. Change it to dump.rdb and save. Then restart redis: service redis-server restart

@julian

It was already dump.rdb so I left it that way. Restarted redis and still no forum.

Could the directory structure be at fault? I didn't have the new redis at the location you pointed to, it was at /var/lib/redis/redis-2.8.9. (both redis.conf files point at dump.rdb by the way).

EDIT: It's back now! You da' man. I'm still not sure which is the real redis.conf file though.
