to pickup a dedicated MySQL 5 server from Dell running Linux. I have the option of either getting:
(1x) Quad Core Xeon E5430 2x6MB Cache 2.66Ghz
OR
(2x) Quad Core Xeon E5405 2x6MB Cache 2.00Ghz
They are about the same price. What option is best? The 4 cores but 666mhz faster each core, or double the cores (8), but less mhz per core. Can MySQL 5 even use 8 cores effectivley?
I read the spec is 4 cores, but my linux recognize 8 cores?
Which one is correct?
is this any kind of Intel Processors comes with 32 Cores? Or can anyone Build Dedicated Server with 32 Cores?
As i see today someone offered me via Email Inter Xeon 7450 Processor with 32 Core!!!
So is it Right ?
I have a new server. Is there any way, from the command line if possible, to tell how many processors and cores my new server has?

Would a dual core CPU with a higher clock speed do better than a quad core CPU with lower clock speed? For instance, would a dual core 3 Ghz processor do better than a quad core at 2.4Ghz?

My older host that is hitting CPU limits and slowing and having times of outages, suggest i take their high end 4 CPU cores (Intel Clovertown E5310 or better), SAS/SCSI drives (in RAID), 8 GB memory for just $250/month (basic management, no control panel).
CPU is my weak point so should i consider 8 cores?
I can add 3 times the volume of traffic once I'm capable of handling it.
4 or 8 cores? How much more will 8 cores cost?

servers for a freehosting project and came across a good quote on some dual quad core amds for $320 a month. Is this about right? I don't want to give the exact location away as this was a custom quote but it's located in chicago. The network is Internap FCP optimized with internap, level3, and comcast.
Specs:
Quad Core AMD OpteronŽ 2376; 2.3 GHz,6M Cache,1Ghz HyperTransport
2 x 500GB 7.2K RPM Serial ATA 3Gbps 3.5-in Cabled Hard Drive

I might get a couple more for virtualization.
I have 2 problems:
Firstly I wonder if there is any possibility to limit the number of cores the plesk backup zipping tool uses? This pigz takes up all my CPU. Is there any way I can reduce the amount of cores it uses because all my websites are down every time a backup takes place for around 3 minutes.
Secondly I get the following in my syslog:
1 baby plesk sendmail[20189]: Error during 'check-quota' handler
I don't know what is wrong. I think it's since the upgrade to Plesk 12. I now have 12.0.18 Update #13.
The code name for the upcoming 12 cores cpu from amd will be named Shanghai. It will be based on 45 nanometer.
But will 12 cores really be necessary for small/medium websites? not to mention the big ones?

I have recently upgraded mysql server from 5.0.75 to 5.1.31 on my Ubuntu server 9.04 32 bit. After that when I am running phpmyadmin it is printing a warning :
Your PHP MySQL library version 5.0.75 differs from your MySQL server version 5.1.31.
Since my /var partition is full, so I moved /var/lib/mysql to /backup/mysql/.
Seems all the files are copied and I changed my.cnf reboot mysql, but all the web sites using db is not working anymore..
I installed the MySQL binary packages in /usr/local/mysql/ after removing the MySQL RPM package. MySQL is functioning when I executed /usr/local/mysql/bin/safe_mysqld. I reinstalled MySQL before I installed PHP. When I used a PHP script to access a MySQL database, it outputs an error:
Code:
Warning: mysqli::mysqli() [function.mysqli-mysqli]: (HY000/2002): can't connect to local mysql server through socket /var/lib/mysql/mysql.sock in index.php on line 2
However, I installed MySQL in /usr/local/mysql, not in /var/lib/mysql. How do I fix MySQL?
Which server for mysql only?
This is sort of a continuation to this thread here
Based upon the screenshots I provided below. What server would best suit my needs. I need this server to be able to handle the mysql usage and server load.
This server will be only for mysql. The rest of the site (html, videos) will be hosted on a different server.
If you think these servers are not enough for this please let me know any suggestions you have pertaining to server specifications.
Server 1:
Dual Core
Core 2 Duo E4500 2.2Ghz 2MB Cache
500 GB SATA II Hard Drive
2 GB DDR2 SDRAM
Server 2:
Dual Core
Core 2 Duo E8400 3.0Ghz 6MB Cache
500 GB SATA II Hard Drive
4 GB DDR2 SDRAM
Server 3:
Quad Core
Core 2 Quad Q9300 2.5Ghz 6MB Cache

i have install a durpal on my centos server(php5,mysql5,suphp),
for some feature,
i get a lof of error like
---------
Warning: MySQL server has gone away query
---------
i try to google to find some solution,
but the issue is still here,
do you know any problem make this?
I have an older script that works well on the config below. Can anybody know where I find such boxes?
PHP version 4.4.7
MySQL version 4.1.22-standard-log
My site is getting big and my server can barely hold all the mysql processes.
Once I had a similar problem with bandwidth because my media files were eating quite a big chunk of it. So, I just bought a media server and changed some HTML to hotlink all the media from the media server. I would like to do something like that with my MySQL databases, to get some load off my main server.
Should I get my current host to cluster another server for mysql? Or can I use a completely different server (from a different webhost) for mysql?
I have A and B server, i linked a cross cable in both server second ethernet port.
I have A as 10.0.0.1 (eth02) and B as 10.0.0.2 (eth02).
Both can ping to each other.
Now how could i setup 10.0.0.2 mysql to accept connections from 10.0.0.2?
The idea is to setup in A server to be able to backup mysql or write to B server.
I have an issue with one of my scripts,it wont run on mysql 5.x
if its possible to run mysql 4.x and 5.x on the same server?
as you know most of servers use utf8 for mysql charset
1- i use following command to backup as utf8
PHP Code:
mysqldump -u root -p123 --default-character-set=utf8 forum > /db.sql
But it is latin1 as you see following
PHP Code:
CREATE TABLE `access` ( `userid` int(10) unsigned NOT NULL default '0', `forumid` smallint(5) unsigned NOT NULL default '0', `accessmask` smallint(5) unsigned NOT NULL default '0', PRIMARY KEY (`userid`,`forumid`)) ENGINE=MyISAM DEFAULT CHARSET=latin1;
why?
How would you offer MySQL 4.1.x and 5 on the same server for your customers?
Would you just change the port of MySQL 5, for instance 3307 so that both versions can coexist?
we got this error on mysql db after that we have change the my.cnf value
Description : MySQL server has gone away. Please contact with your host provider, the connection time should be increased a little.
It's the reason of the session issue (I see that sometimes it's caused on the session table update). It seems like there are some problems with search.
here's my.cnf how can we fix this prpblem?

I didn't find a way to do it. How to have MySQL 4 and 5 on the same server?
View 5 Replies View RelatedHow do I get MSSQL Server and MySQL working on the same server?
I have MySQL running but in PHP.INI when I uncomment the extension=php_mssql.dll line MySQL stops working.
Why is this?
telling me that mysql is hitting loads of 25, which he says is very high and i don't quite know what it means. He is strongly recommending that i shld get another dedicated server for mysql alone.
So can i get some advice on how I can assess the validity of his recommendations? I see that my CPU is load is hitting 125-150% daily. So i suppose there is some truth?
He is recommending that i get a raid-5 which is best. How can i know a suitable configuration of a new server to get? Of course, if i got all the money in the world i shld buy the best. But with constraints on budget, i want to get one (if i really need a new server) that is good for current loads with some projected margins for growth.
I've a huge site that runs on PHP and MYSQL, I'm going to get a dedicated server and make it for MYSQL so I need to know what server should I get for MYSQL ?
does it need to have lots of ram or should I get high CPU ?
as default,we may install all the feature on the server,
but i find some shared hosting server provider install web httpd on the front,
and mysql on another one,
could you share your experience about how do you do now?
It possible to run mysql on differnet server
iam haveing cpanel server
so it possible to run mysql for only one account on different server
i know about remote sql,but i think it wont work for only one account
please advise me for this
I did an apache rebuild and about two hours later, my mysql stopped working.
So i tried various rebuilds to see if perhaps it was suoshin (this caused php to stop working on my server before) but to no avail, this hasnt fixed it. I cant even access the databases via phpmyadmin.
I've restarted the mysql server, apache, i've rebooted a couple times. I don't know what to do.
