I have successfully upgraded PHP 4.3.9 to PHP 5.1.6 and MySQL 4.1.20 to 5.0.48 and everything appears to working properly. Couple of questions:
1. Will the databases that were created under 4.3.9 automatically work under 5.0.48? Or do I need to do anything to them?
2. The database information appears to be fine under phpMyAdmin, but I noticed a new database file is now showing. It is named "information_schema". What is this file and is it a new part of MySQL 5.0.48?
3. Does phpMyAdmin 2.6.3 work fine with MySQL 5.0.48? Or do I need to upgrade that as well? And if so, what version works with 5.0.48?
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?
For some reason mysql wont start, i have tried restarting mysql but it wont, it says FAILED. The mysql.sock file seems to have disappeared and i cannot find it anywhere.
I 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?
I'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?
I'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
I have a number of web sites on a dedicated server. Some of these web sites are a few years old. Are there any issues upgrading from MySQL 4.1 to 5.x? Are there web sites that may have compatibility issues?
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.
I'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.
I'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:
# rpm -i MySQL-server-standard-5.0.27-0.rhel4.i386.rpm warning: MySQL-server-standard-5.0.27-0.rhel4.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 error: Failed dependencies: MySQL conflicts with mysql-4.1.20-1.RHEL4.1.i386 MySQL-server conflicts with mysql-server-4.1.20-1.RHEL4.1.i386
I guess that means i have to uninstall mysql 4.1 first.
ok...
# rpm -e mysql-server-4.1.20-1.RHEL4.1.i386 warning: /var/log/mysqld.log saved as /var/log/mysqld.log.rpmsave
Let's try to install it now.

Ok, let's remove that.

Does upgrade work?

I 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
loading a phpinfo() shows that the mysql variable "Client API version" on my server doesn't match the version of mysql installed ( 4.0.20 when mysql version is 4.1.21).
Can this cause trouble and php or mysql errors on scripts i'm running?
I'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.
i've been using 4.1 without problems but now i'm switching servers and i am wondering whether its a good idea to go for ver 5. How do they compare in terms of performance/security etc? Whats recommended for web use?
Would 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.
A table in my DB got crashed and I repair it via phpmyadmin it gives me status that its repaired but when I browse it, it says table is marked crashed.
started programming for web about a year ago (PHP, mysql, xml etc ) and am completely addicted. Having no prior experience in computing and have been hosting sites on shared server packages. I would, tentatively, like to start hosting my sites on a dedicated servers as i have now realised that it gives you more control over things like security, php / mysql extensions and config files.
I thought i'd start the process on a vps first and make some mistakes there, as i know it can get pricey with dedicated server. A friend reckoned that i should start with Ubuntu on linux (i have no experience with linux, but would like to get involved).
First of all does anyone now any good, cheap vps providers (i've looked at vpsland, feedback? better alternatives?)
and also, can you guys recommend good books/resources that will get me started with server administration (idiots guide!!) or just any good hints to get going! Should i set up on a web server on own pc first or jump in on a vps?
I have a medium size forum with around 100 members online in 15minutes.. as the days gone .. sql data has become quite big .. and now most of the times mysql uses 100% ... any help regarding this .. how to optimise sql .. or may be RAM upgrade needed ?? i already have 3GB ram with xeon 3010 processor
Suddenly all sites on my servers show this error when access them(sites with db) Could not connect: Client does not support authentication protocol requested by server; consider upgrading MySQL client
I try to google this error but seem all instructions do not help much as i can not update every user 's password on server.
