02:02:20 GMT <winteriscoming> hey guys, is there a way we can find how many hashes currently in a redis db?
05:09:23 GMT <greg_> Hellow dear forum, i have a question regarding communication of redis and haproxy
05:18:38 GMT <greg_> if redis configured with authen password then it is allowing connection from haproxy with tcp mode - is there any haproxy configuration parameter that can introduce the password?
06:38:18 GMT <minus> greg_: you need to send the AUTH command in your checks, there's no parameter as HAProxy does not understand the redis protocol itself
06:50:45 GMT <greg_> i tried parameter "reqadd Proxy-Authorization:\ Basic\$password" but still getting  Error: Server closed the connection
06:51:42 GMT <minus> redis doesn't speak HTTP
06:52:15 GMT <greg_> i see
06:52:38 GMT <greg_> but which parameter i can use to introduce the password
06:52:57 GMT <minus> you should have commands like `tcp-check send PING\r\n` and need to add a tcp-check send AUTH... too
06:53:24 GMT <minus> or do you want clients to be able to use redis through HAProxy without password?
06:53:54 GMT <greg_> tcp-check send AUTH\ auth_key\r\n
06:54:01 GMT <minus> http://blog.haproxy.com/2014/01/02/haproxy-advanced-redis-health-check/
06:54:16 GMT <minus> that only works for the checks though
06:54:41 GMT <minus> i've never used HAProxy with Redis with authentication, so not sure if it works
06:54:57 GMT <greg_> i must use password
06:55:54 GMT <greg_> thanks for the information minus
08:34:06 GMT <masber> hi
08:34:54 GMT <masber> I am new to redis, redis service doesnt want to start. Logs says "Opening Unix socket: bind: No such file or directory"
08:35:17 GMT <Mattias> When I set maxmemory with maxmemory-policy to noeviction, how does that work? Is the data, when using save, release from memory when it writes? Or will it just keep on increasing? Using it to store sessions in magento and I want to limit redis to 64M ram since php, mysql and a lot of other stuff runs on the same server.
08:35:39 GMT <Mattias> Or is it up to magento to clear it perhaps?
08:36:00 GMT <Mattias> maybe there is a better policy for me? Not sure which to pick
08:44:12 GMT <masber> ok the problem was that the path to write the socket was missing
08:45:34 GMT <masber> now I can see on the configuration file "unixsocketperm 755" is that the permissions I have to setup on "/var/run/redis/redis.sock"?
08:57:49 GMT <masber> do i need to create the redis.sock file myself?
09:00:13 GMT <Mattias> masber: socket files are created by the application, it's a special socket file
09:00:33 GMT <Mattias> It'll be created when you get redis up and running
09:02:05 GMT <masber> Mattias, ok.. it is not creating the file then... because it says permission denied, I put 777 as permission to folder /var/run/redis
09:02:32 GMT <Mattias> masber: which OS?
09:02:38 GMT <masber> centos 7
09:07:04 GMT <masber> Mattias, I also changed the folder to /tmp/redis.sock but same result
09:07:26 GMT <Mattias> Hm, I just did the same on centos 7 but I have no issues. Did you modify the redis.conf file?
09:08:05 GMT <Mattias> I assume you used the official package "yum -y install redis"
09:09:08 GMT <masber> Mattias, ok, let me uninstall and reinstall it
09:11:27 GMT <masber> ok, it is working now
09:11:32 GMT <masber> not sure what was wrong
09:11:42 GMT <masber> Mattias, thank you!!!
10:04:00 GMT <masber> ok
10:04:04 GMT <masber> I got redis working
10:05:20 GMT <simmerz> Hi. Running redis for a third party app. For some reason, a BGSAVE tries to write to /dev/fd0 at random times. I can’t figure out why, but it’s causing redis to fail with a MISCONF
10:07:16 GMT <badboy_> simmerz: someone re-configured that instance? :)
10:07:34 GMT <simmerz> nope. only I have access to it, and no one’s tampered with it
10:07:39 GMT <badboy_> Redis doesn't randomly change it's dump file path
10:07:42 GMT <simmerz> if i restart redis, BGSAVE works
10:07:52 GMT <badboy_> are you sure? is it available on the internet? passwort protected?
10:07:53 GMT <simmerz> and did all of yesterday, until 1.27 this morning
10:08:00 GMT <simmerz> only accessibly via my ssh key
10:08:27 GMT <simmerz> no root access
10:08:47 GMT <badboy_> Redis by default listens on an tcp port, if that port is open to the internet anyone can access it
10:09:06 GMT <*> simmerz  looks
10:09:17 GMT <simmerz> what config setting sets it to write to floppy?
10:09:49 GMT <badboy_> https://github.com/antirez/redis/blob/unstable/redis.conf#L255
10:10:07 GMT <badboy_> and https://github.com/antirez/redis/blob/unstable/redis.conf#L245
10:10:42 GMT <simmerz> thanks for the pointers
10:11:12 GMT <simmerz> and yep, didn’t realise it was bound to 0.0.0.0
10:11:27 GMT <simmerz> so someone was fiddling with the redis instance itself
10:11:34 GMT <simmerz> now bound to 127.0.0.1
10:14:04 GMT <badboy_> ;)
10:15:14 GMT <badboy_> https://web.archive.org/web/20160419180101/http://antirez.com/news/96
10:16:04 GMT <simmerz> thanks again :)
10:16:10 GMT <simmerz> now a little more secure
15:26:33 GMT <Habbie> the redis-lua test suite checks that 'list-max-ziplist-entries' is in the output of CONFIG GET *
15:26:34 GMT <Habbie> but it was removed
15:26:42 GMT <Habbie> can anybody recommend a key that has been stable in that output?
15:42:04 GMT <badboy_> bind, pidfile, logfile, ...
15:42:16 GMT <badboy_> literally everything else that's not exposing some internals
16:08:08 GMT <Habbie> badboy_, ack
16:08:10 GMT <Habbie> next question
16:08:13 GMT <Habbie> is nil allowed in -commands-?
16:08:26 GMT <Habbie> i.e. the null bulk string "$-1\r\n"
16:10:31 GMT <Habbie> redis says -ERR Protocol error: invalid bulk length
16:11:10 GMT <Habbie> when i send "*3\r\n$3\r\nSET\r\n$-1\r\n$3\r\nbar\r\n"
16:23:55 GMT <badboy_> then you know it: nil is not allowed ;)
16:24:01 GMT <Habbie> figured
16:24:23 GMT <Habbie> redis-lua 2.0.4 would just skip a nil, hanging the connection while redis waits for another argument
16:24:26 GMT <Habbie> 2.0.5 maps it to ""
16:24:33 GMT <Habbie> which feels wrong to me as in replies "" and nil are clearly different
16:24:43 GMT <Habbie> i'm going to propose to make it an error in redis-lua itself
16:24:45 GMT <Habbie> thanks badboy_
16:51:27 GMT <trump4redis> How to choose the expiration time length for redis keys?
16:52:07 GMT <Habbie> trump4redis, do you mean 'how to tell redis' or 'how to decide'?
16:52:53 GMT <trump4redis> How to decide?
16:53:10 GMT <Habbie> well, that's hard to answer without more information
16:53:17 GMT <Habbie> what kind of info is in it? why should it expire?
16:53:36 GMT <trump4redis> it is ebay product links
16:57:17 GMT <trump4redis> Habbie: it is ebay product links. what should be an appropriate time length?
16:57:30 GMT <Habbie> i asked two questions
16:57:34 GMT <Habbie> you gave 0.5 answers
16:58:35 GMT <trump4redis> Habbie: 1.ebay product links. 2. some product may become no longer available, i.e. ended auctions.
17:05:48 GMT <Habbie> trump4redis, well, you can see the end time for an auction
17:09:13 GMT <trump4redis> Habbie: As they are all different, I'm hoping to use some kind rule of thumb, i.e. not too long or too short amount of time. but lacking of experience to begin the guess.
17:09:24 GMT <Habbie> so what happens if you expire too soon?
17:09:29 GMT <Habbie> or what happens if you expire too late?
17:09:33 GMT <Habbie> what bad things would happen in those cases?
17:11:43 GMT <trump4redis> <Habbie> expire too soon, will lead to unnecessary API calls, hence reduce paging loading speed. expire too late, some listings will no longer be available, hence defeats the purpose of the whole app.
17:17:12 GMT <minus> you can set different expiration times on different keys
17:33:55 GMT <trump4redis> minus: cool, but i was hoping for something even more simpler.
19:27:42 GMT <Inge-> a portent of things to come
23:11:27 GMT <momoterr_> does master slave gives high throughput?
23:11:39 GMT <momoterr_> scalling without clustering?
23:12:54 GMT <momoterr_> is this achievable with sentinel
