MySQL :: 16 Characters Limitation About A Username Length
Apr 27, 2009I am unable to create a user in mysql with 20 characters length. I am getting the annoying error message about 16 characters limitation about a username length. I have tried to increase the character user limit length to 32 characters using the following commands:
mysql -uroot -p
use mysql;
alter table `user` modify `User` CHAR(32);
FLUSH PRIVILEGES;
quit
service mysqld restart
But after all of this was done I was and I am still unable to connect to mysql anymore with/without password.
Content Limitation With Vps
Aug 29, 2007I know, it could depend on the company, where you have your vps. So it is a general question. Do I have to take care, which content I put on the machine, assuming that it is _not_ illegal, at least in the European Union? So I do not mean illegal mp3 or warez.
But what about erotic things. For sure, I do _not_ mean hardcore-pornography, but I think of erotic paintings, which you can see in Europe at prime time on tv and these paintings got prizes already, while in other parts of the world, it would be banned.
So do I have to check this exactly before a sign-up?
Apache Limitation
Nov 14, 2007Does anyone know if there is any limitation for the number of domains that apache webserver can host? I think there is a limitation specified depending on the operating systems, but I wasn't able to find this information anywhere so far.

View 4 Replies View RelatedGeographical Limitation On Bandwidth
May 25, 2007I'm currently hosting in Texas and Florida, and one of the things I enjoy is that I can move backup or other files between servers at 3-5 MBps.
When doing a speed test from Liquidweb (Michigan, over Level3), I found that I'm not able to get quite 1 Mbps. Same from DedicatedNow (New Jersey, over Savvis) to Texas (The Planet). Is this just a limitation of geography and the overall infrastructure going the distance from the south US to the North?

Plesk 12.x / Linux :: Bandwidth Limitation Button Not Showing In Domain Control Panel
Jun 27, 2014Bandwidth limitation button not showing in domain control panel
I am running Plesk 12.018 on CentOS 6.5. with ~75 domains hosted. All of them are allowed unlimited traffic and have Apache + Nginx installed and configured via Plesk.
Today I need for the first time to set a bandwidth-limitation for a domain, but I can't find a button for controlling it in the domain control panel.
I've checked I've mod_bw installed and have set the permissions for controlling server performance in the custom plan for the specific domain.

Installed MySQL In /usr/local/mysql But Error In /var/lib/mysql
Jan 21, 2007I 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?

Feb 11, 2008I recently had a harddrive failure and luckliy I can still access certain directories on this failed drive. I can still access the /var/lib/mysql/ directory which holds all the users databases and have backed all these up separately using tar.
Now what I need to know is how do you restore these database files to another server? I tried simply untar'ing one of these to the new servers /var/lib/mysql/ direcotry and it stuffed Mysql up - it went offline. I had to get a cpanel tech to bring Mysql back online.
how can I get these database files to fully work on a new server?

View 5 Replies View RelatedMySQL Monitor Shows MySQL As Offline When It's Not
Jan 15, 2007I've been racking my brains with this problem for the last couple of months and have made zero progress. I've asked a lot of people if they know what might be wrong here, but none of them have any idea.
Basically, the problem is that any sort of service monitor I put on my server shows MySQL as being down/offline, even when I know for sure it's up and running perfectly fine. All other services report a green light.
The mysqld service is running on port 3306, which is open both inbound and outbound on my APF config, so as far as I can tell it's nothing to do with the firewall (I won't rule that out though).
The other odd thing is that MySQL shows a green light within WHM, but not anywhere else.
Does anyone know what might be wrong here? Am I missing something entirely fundamental and obvious?

Uninstall MySQL 3.23 And Install MySQL 5.0
Mar 28, 2007I've rented a dedicated server that comes with Red Hat Enterprise Linux 4 and MySQL 3.23 but I need at least MySQL 4.1 or higher. My knowledge about GNU/Linux is very limited, so I've read some documents at mysql.com and now I think I have to follow these steps:
1. Uninstall MySQL 3.23 with this command line:
shell> rpm -e mysql-*.rpm
2. Install the server and client RPMs of MySQL 5.0:
shell> rpm -i MySQL-server-VERSION.i386.rpm
shell> rpm -i MySQL-client-VERSION.i386.rpm

Upgrade From MySQL 4 To MySQL 5
Jun 3, 2008I'm trying to upgrade from MySQL 4 to MySQL 5 for performance reasons. MySQL 4 was working great so I decided to just go ahead and upgrade to MySQL 5 via CPanel. The upgrade appeared to go fine however I now get this error when trying to start MySQL.
/usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)' Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists! mysql has failed, please contact the sysadmin (result was "Warning, no valid mysql.sock file found.mysql has failed").
I went ahead and did a forced re-install of MySQL 5, but that didn't help. Apache has been updated as well since then, but that did no good, and the MySQL process isn't starting at all.
Its CENTOS with PHP5.
Difference Between --with-mysql And --with-mysql=dir
Jun 21, 2007I am not sure what difference between --with-mysql and --with-mysql=/usr to compile php 4.4.7
because I get error message when I use --with-mysql=/usr
the error message is like Mysql header can not be found or similar thing.
it ok when I use --with-mysql
so, I am afraid that can I use php and mysql without problem by using --with-mysql?
Upgrade Mysql MySQL 4.1 To 5
Jan 20, 2007I'd like to upgrade my current mysql 4.1 version to mysl 5, but i can't find a good tutorial or explenation! I've been searching for hours now without any good results.
I've downloaded the lastest stable mysql 5 .rpm, and tried to install it with rpm -i mysql.version.rpm, but it says the following:

ok...

Ugrading From Mysql 4.0.x To Mysql 5.0.x
Feb 16, 2007I have a big issue importing 4.0 databases with mysql 5.0.27.
I did a mysqldump -pxxxxx --force --all-databases > file.sql on server with mysql 4.0
But when I tried to import the file on server with mysql 5.0, this is what I got:
ERROR 1064 (42000) at line 2: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'database' at line 1
I even tried to force import and I got:
ERROR 1046 (3D000) at line x: No database selected for every database.
I checked sql file and CREATE DATABASE xx and USE xx were both added.
I tried this with a single database and worked but with all not

MySQL = How Much RAM
Oct 22, 2008I'm trying to understand, generally, on a Hybrid VPS with 1gig guaranteed/4gig burst- for small sites that might be installing stuff like Wordpress, a Forum, Joomla!, etc., how many MySQL databases this system can support.
I realize traffic would be a major factor but for discussion sake lets assume an average of 50 users for each db with a peak of 100 users.
Just trying to get a 'rule of thumb'. Wondering also, how much RAM (resources?) an idle db consumes.

PDO MySQL
Jul 18, 2008Would enabling PDO and PDO Mysql modules in apache compile (via whm) be a bad idea? Any possible conflicts or warnings?
It says
(UNSUPPORTED EXPERIMENTAL) Includes SQLite support. Other drivers (freetds, oracle, etc) can be installed with PECL. If you use rawopts to add them during compile then you will have to have them '=shared' and *NOT* do the PHP "versioning" option. Custom opt mods for PDO extensions should also do the "versioning" logic this one does.
