RE: [squid-users] configuring Eliezer RPMs for CentOS 6 for SMP

Here's my filesystem:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/system-root 92755960 7827884 80193308 9% /
devtmpfs 8177376 60 8177316 1% /dev

And permissions:

# ls -al /dev/shm
total 5840
drwxrwxrwt 2 root root 140 May 22 17:26 .
drwxr-xr-x 19 root root 4080 May 22 17:15 ..

-rw------- 1 squid squid 7864392 May 22 17:29 squid-cache_mem.shm
-rw------- 1 squid squid 0 May 22 17:29 squid-squid-page-pool.shm

Notice that there are already squid files in the directory... so permissions should be good. Maybe the size is the problem?

If squid can't create the shm file, you should check your OS configuration. It's not squid fault, the server Os has to be configured to provide enough shared memory to squid.

Most of the time, it's enough to mount tmpfs mounted as /dev/shm, but I'm not familiar with SuSE installation defaults.

This won't work in smp mode. Each worker needs a dedicated cache_dir,
except for rock store. But your squid never reached that point.

The way you did all workers will try to use both cache_dirs. I guess
you want one for each worker. So replace those two lines by:

cache_dir aufs /ssd/squid/cache${process_number} 45000 64 1024

That way each worker will use only it's own, exclusive, cache dir.

> workers 2

Ok, you are trying to use 2 workers.
