*WHM>Reseller Center

*Make sure that A records are setup for the private name servers in the zone file as well.

If MySQL refuses to start, please do the following:

1. Check the logs! `tail -f /var/lib/mysql/$(hostname).err`
2. Correct the permissions on /tmp. `chmod 1777 /tmp`

This should in most cases resolve your issue.

There may be a time where all of a sudden all your users are set to an unlimited quota. To fix this, please take the following steps:

1. Confirm quota reports are failing with repquota (repquota -ua)
2. If quotas are reported right, rm -f /home/*/.cpanel/datastore/quota*
3. Verify that quota support is enabled.
4. Determine quota enabled file systems with `mount` or `quota -v`mount -o remount,usrquota /mount/point
5. Reinitialize quotas with /scripts/initquotas
6. Completely rebuild all quota databases with /scripts/fixquotas

This should resolve your issue.

There may be times when you may not be ableto connect to WHM. Do the following to resolve the issue.

1. Check the error log!
2. Check to see if cpsrvd running:
ps auxww | grep cpsrvd
3. Check to see if the required ports open, and bound by cpsrvd?
netstat -lnp | grep :208
iptables -L -n
4. Check to see if the traffic reaching the server:
tcpdump -n dst port 2087

One of these should resolve the issue and will allow you back into the WHM.

Some symptoms that I noticed before I figured out the problem was:

- /var was 100% full

- top showed mysql at the top using 98%-100% CPU (but the load was not too bad)

- ‘mysqladmin proc’ showed many ‘killed’ and sleeping connections for 10000’s of seconds

- mysql would not restart (failed on stop and start)

- when I looked in /var/lib/mysql there were many large files like the following:

-rw-rw----   1 mysql mysql  743908873 Nov 19 20:38 server23-bin.000001

-rw-rw----   1 mysql mysql  195841952 Nov 23 07:19 server23-bin.000002

-rw-rw----   1 mysql mysql   58204739 Nov 24 09:28 server23-bin.000003

-rw-rw----   1 mysql mysql         79 Nov 24 11:56 server23-bin.000004

-rw-rw----   1 mysql mysql  122848408 Nov 28 08:11 server23-bin.000005

-rw-rw----   1 mysql mysql  148310361 Dec  2 05:21 server23-bin.000006

-rw-rw----   1 mysql mysql  352310491 Dec 14 05:59 server23-bin.000007

-rw-rw----   1 mysql mysql   23323812 Dec 15 14:12 server23-bin.000008

-rw-rw----   1 mysql mysql 1073741989 Feb 15 09:28 server23-bin.000009

-rw-rw----   1 mysql mysql 1073742439 Mar 24 00:00 server23-bin.000010

-rw-rw----   1 mysql mysql  654110720 Apr 11 18:54 server23-bin.000011

-rw-rw----   1 mysql mysql      39881 Apr 11 18:59 server23-bin.000012

-rw-rw----   1 mysql mysql        264 Apr 11 18:56 server23-bin.index

The solution is easy:

- edit /etc/my.cnf and comment out the following lines:

# log-bin
# server-id=1

- save, close, and stop mysql

- remove those ‘bin’ files in /var/lib/mysql
- then restart mysql
