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 keep getting this error :
MySQL Error : MySQL server has gone away
How do I fix it?

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
500 GB SATA II Hard Drive
4 GB DDR2 SDRAM
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 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.
lets say my web server IP is A, and my dedicated MySQL server is B.
Apache and PHP have been installed on A. MySQL server has been installed and configured on B.
Im just wondering, do I still need to install MySQL client on the web server A?
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?
What can you do to stop so many users on your server that use mysql as apart of their website from getting this message: MySQL server has gone away
Like there has to be something installed or configured on the server that causes this as well, as I know people are taking too long to load something and it through that message, but it has to be something you can do server wide to get reed of it?
I have setup php and mysql on a windows IIS 6 server. php has installed fine and works but I have 2 problems
1. When i browse to http://localhost i get a 403 error but when browsing to http://localhost/index.php it works fine. It makes me think that the server does not know what extension to default to when doing a directory listing
2. I have phpmyadmin installed and the cfg file is set to do a 'config' authentication. That works but everytime i go to submit a form to create a new database or anything i get prompted with an HTTP user/pass. I'm not sure if this is a phpmyadmin issue or a php configuration issue
I got some questions about dedicated mysql server.
I read some things about compression used, should I give this a try?
Image
Any other tweaks? The current os is centos (The server is donated) I plan to switch to debian etch or freebsd 6.2
I got my.cnf tweaked right for the 2gb of ram I think but seems alittle slower then when it was on localhost, I was thinking dedicated mysql server would be quicker, its slow enough that my light weight mysql pages are running much slower
As for the 100mbit line, what else do you guys run? I'm thinking of going to 1000mbit so I'd get about 200mbps atleast, any better way?
1)i want to delete a folder in /var/lib/mysql,
when i use "ls" to check ,it shows with (space)foldername,
i use rm -rf ./foldername, it failed,
and i use rm -rf ./(space)foldername, oh no,all the files in the /var/lib/mysql are gone,
2)i do not have the backup files of the folder at all.
3)how can i rebuild the system files of the mysql server with a smooth way?
Running CentOS 4.6. Currently, the my.cnf contains:
Code:
[mysql.server]
user=mysql
basedir=/var/lib
If I moved all files and directories under /var/lib/mysql/ to /harddisk3/mysql/ what do I enter for the basedir path?

I was trying to upgraded MySql on my godaddy V.dedicated server..
And basicly ive screwed it up somehow.
I need to get back up and running and could do with some help on the best way to do that..
Ive visited the MySql website.. ive been playing with the shell (a little too much thats why its screwed up) so i can access the server via that and the server is running
Operating System: Red Hat Fedora Core 2
Can anyone point me first of all to the right download. and maybe point me to a tutorial or give me some advice on installing.. if ive messed up mysql does this also have any impact on the php or anything else?
how many of you (Windows Hosting Providers) have MySQL (any version) support on your servers?
