Number of database I think

 

[xml]

Number of database I think

Thats what I thought also, but in redis.config the default number of clients is 10,000. Dose that mean 10,000 databases?

 

[andybond]

No , single instance of a DB. Connections from client are different.

You can run multiple REDIS database though - one for say CSS , one for session cache and one for guests. That would be 3 DB.

 

[Xon]

Ok, save 86400 1 should do?

Yup.

It is the number of simultaneous connections to Redis from php, due to how XF works it is basically a proxy for how many users you have at a given time.

 

[xml]

Yup.

So in my case I have only 1 connected client which is php? and this client (php) is used as a proxy to perform the requests of my forum visitors?

Think I got it, is this okay?

$config['cache']['sessions'] = true;

$config['cache']['enabled'] = true;
$config['cache']['provider'] = 'SV\RedisCache\Redis';
$config['cache']['config']  = array(
        'server' => 'x.x.x.x',
        'port' => 6379,
        'compress_data' => 6,
        'password' => 'removed',
        'use_lua' => true,
        'read_timeout' => 1,
        'timeout' => 2,
        'database' => 2,
    );

so i have a question do you have to create a databse for it or its just a value you have to set ? its my first time doing this

 

[shimspedy]

can this work on Bluehost?

 

[Xon]

Generally 'no' for shared hosting, also it is outside support for this add-on for the hosting side of running Redis.

It's just a value you set.

This is my configuration for Redis 5 on Centos 7:

bind 127.0.0.1
port 6379
daemonize yes

save 86400 1
stop-writes-on-bgsave-error no

maxmemory-policy allkeys-lfu
lfu-log-factor 10
lfu-decay-time 1

dir "/var/lib/redis"
logfile "/var/log/redis/redis.log"

Any comments on this?

Hi

What advantages do we get setting persistent = true?

Thanks.

 

[Xon]

It uses 'persistent' TCP connections which survive the php-request meaning you aren't paying for the setup & teardown every request to redis

Hi

Regarding "Count Moderated Threads", should we enable this to have a shared cache? Will this have some performance benefits if activated?

Isn't any real benefits to having it enabled, it just makes the query more complex as it becomes per-person instead of sharable with other users

Are you using pre-fork apache webserver? That is apparently breaking after allocating more than ~2mb, which is really really low.
