Mysqld Using 100 Percent Of Cpu
Apr 10, 2007I've got a strange situation here. We have some software which we run on multiple servers. As of today the software is using 100 percent (sometimes more) of the cpus.
Here is the result from top. It's usually far worse using 100 percent of both cpu's almost all of the time. I just restarted, but the server load is climbing to 20+. Any idea how I can figure out what is going on? The same software on two other identically configured servers runs fine. This server has had no problems for over 6 months, but suddenly this started today. The server is a dual opteron with 4GB of ram. The databases are innodb thus the high memory usage for mysql (innodb buffer pool size)

Monitoring A User's SSH? Also... Mysqld Running At 103%cpu & Stats Overload Emails
May 15, 2007I have 3 questions.
1.) I have a user that's kinda knows a lot about linux. More than me. He has a lot of stuff on the system which I have no idea what it is. Is there any way I can install a SSH log, so I can monitor what he does in shell?
2.) My server seems REALLY sluggish. I ran a top in shell, and mysqld was taking up from 70% to 110% of the cpu. Is there any way to fix this or find out why? I've restarted the server, and it's fluctuating between 50% and 90% now.
3.) I think this MIGHT be related to the sqld issue, but I've received about 12 emails saying
Quote:
"[statscheck] Stats/Server Overload on my server". "MPORTANT: Do not ignore this email.

Best Resolve DNS IP

View 4 Replies View RelatedCannot Resolve Any Domain Name
Aug 28, 2008I am new to the dedicated servers. I have just upgraded myself to a dedicated machine.
I am getting error "couldnt resolve host" at every domain name when I type like
wget http://google.com
wget http://yahoo.com
I searched over internet and found some people telling that I should put nameserver to /etc/resolv.conf?

Hostname Does Not Resolve To Any IP
Oct 31, 2009I hope your day is going good. I've been trying to fix a problem I had all week. I receive daily email notification that "example.[url]" does not resolve to any IP. However, when in WHM, it already contains Server Main Ip: 208.53.183.125. I've tried a few solutions from the web, but to no avail:
IMPORTANT: Do not ignore this email.
The hostname (example.mydomainname.com) resolves to . It should resolve to 208.53.183.125. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.
Some are all of these problems can be caused by
/etc/resolv.conf being setup incorrectly. Please check this file if you
believe everything else is correct.
You may be able to automaticly correct this problem by using the
'Add an A entry for your hostname' under 'Dns Functions'
in your Web Host Manager
1) Within WHM, I have the following:
-Add an A entry for your hostname (I only have one listed)
Hostname: example.mydomainname.com
Server Main Ip: 208.53.183.125
-Primary/secondary nameserver
Primary Nameserver: ns1.mydomainname.com (A entry = 208.53.181.26)
Secondary Nameserver: ns2.mydomainname.com (A entry = 208.53.181.27)
-Resolver Configuration
Primary Resolver: 66.90.68.25
Secondary Resolver: 66.90.68.26
-Additional IP my webhost gave me to use:
208.53.181.26 (used in primary name server)
208.53.181.27 (used in secondary name server)
208.53.181.28
-Current DNS Zone listing:
example.com (my website URL that is currently working)
example.mydomainname.com (hostname I made myself that contains the server main IP)
ns1.mydomainname.com (A entry = 208.53.181.26)
ns2.mydomainname.com (A entry = 208.53.181.27)
2) My edit "edit /etc/resolv.conf" contains the following:
Search localdomain
nameserver 66.90.68.25
nameserver 66.90.68.26
Issue: I receive daily email notification that "example.mydomainname.com" does not resolve to any IP. However, when in WHM, it already contains Server Main Ip: 208.53.183.125.
DNS :: Domains Will Not Resolve
Aug 5, 2009I've been having this problem for a while now. I have a dedicated linix server running with the cpanel. I've setup my own nameservers and for the most part it all runs without a problem. However, every now and then the domains will not resolve for many people.
This may only last a few minutes but it happens regularly. There doesn't seem to be any pattern. The server is still available via IP address. Also, any domain name set as a nameserver with the registrar is not affected by this problem. All other domains are affected. This problem has persisted over many cpanel updates.
I have gone through all the nameserver files (I can think of or have read about) looking for something that may be causing this but everything looks normal.
Unable To Resolve
May 12, 2007I have nameservers setup on my server. As I have changed my servers, I need to resolve the sites. I changed the nameservers Ips to resolve to new one:
67.159.33.250 and 67.159.33.251
But my sites and my clients sites are going down.
[url]
And similar report by dnsreport is being given saying that NS didnt responded timely.
Domain Name Resolve Problems In WHM
Nov 4, 2009I have installed WHM 11 on centos 5.3.
Currently I get problems that domains at certain places not open.
Like e.g I write my server IP XXX.XXX.XXX.XXX it works fine and I get ping reply also, but at the same time I write [url]it would not resolve.
Similarly in web browser I write server IP it gives cpanel page but on same computer I write [url]I get page cannot be opened, when I refresh the page at certain times then it would open. Now once it is opened in the same computer it would work fine here.
In some internet connections it works fine i.e no problems, in some connections get similar problems that domains does not resolve properly.
I checked my named service works fine.
Subdomain Doesn't Resolve, But Others Do
Apr 20, 2009I've got several subdomains on the ethoshosting.com server, but I recently created a subdomain (the same way as before) and it doesn't resolve

What gives? (it was a WHM setup via whmcs)

PHP Bug- PHP Can't Resolve Domains, Server Can
Jul 23, 2007My VPS was a clean build 2 weeks ago and so far i have installed cpanel and configured everything and added accounts. I began that one of my scripts that uses gethostbyaddr($ip) was failing to resolve any of the ip's it received. I made another PHP file to test this, with this code:
PHP Code:
<?phpecho file_get_contents[url];?>
Resulting in:
Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: Name or service not known
The thing is, the VPS is resolving domains just fine

Resolve DNS Issues On Cpanel 11.x Beta
Jul 11, 2007I have come accross an issue with DNS in cpanel 11.x , where named.conf is badly configured by cpanel ,
Here is how a DNS report from dnsstuff.com would look because of this :
FAILS for SOA record
Fails for lame nameservers .
Here's how to fix it ,
SSH to server ,
Backup your named.conf file by
cp /etc/named.conf named.conf.back
then
pico /etc/named.conf
Replace
Code:
include "/etc/rndc.key";
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};
options
{
/* make named use port 53 for the source of all queries, to allow
* firewalls to block all ports except 53:
*/
query-source port 53;
// Put files that named is allowed to write in the data/ directory:

dump-file "data/cache_dump.db";

};
logging
{
/* If you want to enable debugging, eg. using the 'rndc trace' command,
* named will try to write the 'named.run' file in the $directory (/var/named).
* By default, SELinux policy does not allow named to modify the /var/named directory,
* so put the default debug log file in data/ :
*/
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
// All BIND 9 zones are in a "view", which allow different zones to be served
// to different types of client addresses, and for options to be set for groups
// of zones.
//
// By default, if named.conf contains no "view" clauses, all zones are in the
// "default" view, which matches all clients.
//
// If named.conf contains any "view" clause, then all zones MUST be in a view;
// so it is recommended to start off using views to avoid having to restructure
// your configuration files in the future.
view "localhost_resolver"
{
/* This view sets up named to be a localhost resolver ( caching only nameserver ).
* If all you want is a caching-only nameserver, then you need only define this view:
*/
match-clients { localhost; };
match-destinations { localhost; };
recursion yes;
zone "." IN {
type hint;
file "/var/named/named.ca";
};
/* these are zones that contain definitions for all the localhost
* names and addresses, as recommended in RFC1912 - these names should
* ONLY be served to localhost clients:
*/
include "/var/named/named.rfc1912.zones";
};
view "internal"
{
/* This view will contain zones you want to serve only to "internal" clients
that connect via your directly attached LAN interfaces - "localnets" .
*/
match-clients { localnets; };
match-destinations { localnets; };
recursion yes;
zone "." IN {
type hint;
file "/var/named/named.ca";
};
// include "/var/named/named.rfc1912.zones";
// you should not serve your rfc1912 names to non-localhost clients.
// These are your "authoritative" internal zones, and would probably
// also be included in the "localhost_resolver" view above :
};
view "external"
{
/* This view will contain zones you want to serve only to "external" clients
* that have addresses that are not on your directly attached LAN interface subnets:
*/
match-clients { !localnets; !localhost; };
match-destinations { !localnets; !localhost; };
recursion no;
// you'd probably want to deny recursion to external clients, so you don't
// end up providing free DNS service to all takers
// all views must contain the root hints zone:
zone "." IN {
type hint;
file "/var/named/named.ca";
};
// These are your "authoritative" external zones, and would probably
// contain entries for just your web and mail servers:
// BEGIN external zone entries
With
Code:
include "/etc/rndc.key";
controls {
inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
};
And then goto bottom of the file and remove
}; at the bottom .
Save file and exit
then test config
service named configtest
if you have done this correctly , it should display something like this:
zone blue.xxx.com/IN: loaded serial 2007070901
zone xxx.com/IN: loaded serial 2007070906
zone ns1.xxx.com/IN: loaded serial 2007070901
zone server.xxx.com/IN: loaded serial 2007071001
zone xxx.net/IN: loaded serial 2007071001
Then restart named by
service named restart
your DNS should be working now .
Server Lost Ability To Resolve Names

it hangs on the "Resolving bit for a long time.
my resolv.conf file is as follows:
Quote:
nameserver 66.90.68.16
nameserver 66.90.68.26
which are the 2 nameservers of my datacenter.
I tried doing a /scripts/upcp --force and I get this:
