Redis Crash

check redis log for clues /var/log/redis/redis.log

 

do what it suggests with redis-check-aof --fix and name of the appendonly file which by default is appendonly.aof at /var/lib/redis/appendonly.aof

Code:

grep appendonly /etc/redis.conf
appendonly yes
# The name of the append only file (default: "appendonly.aof")
appendfilename "appendonly.aof"

 

yeah if it's just caching data, it can be lost and rebuilt anyway

Code:

ls -lah /var/lib/redis
total 163M
drwxr-xr-x.  2 redis redis   42 Jan  1 05:17 .
drwxr-xr-x. 38 root  root  4.0K Jan  1 03:19 ..
-rw-r--r--.  1 redis redis 163M Jan  1 05:02 appendonly.aof
-rw-r--r--.  1 redis redis  32K Jan  1 05:17 dump.rdb

Code:

redis-check-aof /var/lib/redis/appendonly.aof
AOF analyzed: size=170410940, ok_up_to=170410940, diff=0
AOF is valid

Code:

redis-check-aof --fix /var/lib/redis/appendonly.aof
AOF analyzed: size=170410940, ok_up_to=170410940, diff=0
AOF is valid

 

should work that command what does output when run ?

Code:

redis-check-aof --fix /var/lib/redis/appendonly.aof

as to caching did you configure and enable nginx-helper ?

port for you should be 6379 for redis default port, i am using a redis load balanced cluster on port 19001



How are you confirming whether pages are cached ? you can check the nginx-cache key in redis cache in phpredisadmin. I don't see any of those urls in cache

 

how much memory is redis using ? you can grep on the fields of output in redis-cli info command

Code:

redis-cli info | egrep 'used_memory|mem_'
used_memory:9255840
used_memory_human:8.83M
used_memory_rss:12763136
used_memory_peak:12363208
used_memory_peak_human:11.79M
used_memory_lua:78848
mem_fragmentation_ratio:1.38
mem_allocator:jemalloc-3.6.0

 

what version of redis ? 3.0.7 is latest

so update too

Code:

yum update redis --enablerepo=remi --disableplugin=priorities

 

how much memory does that server have ?

 

Could be running up your memory limits on background saves Redis Persistence – Redis and FAQ – Redis did you set overcommit_memory=1 in TCP settings as outlined in 1st post at Redis - How to install Redis server on Centmin Mod LEMP stack | Centmin Mod Community ?

from FAQ
