Hello, I'm learning how to use and manage GTID replication. I have a question on how to manage the size of MySQL.gtid_executed table. I know it can be compressed, but it will grow large regardless. Do I need to purge it periodically? Or there's a size limit for it so it rolls over automatically?

Please help. Thanks.
Ed.

I am trying to move my database from my main hard drive to my home library folder on an external drive.

I am running a fresh installation of sierra 10.12.5 with a fresh installation of mysql 5.7.18 64bit.

I cannot move the database within mysql. I can physically move the database to another location, but I cannot get mysql to use it. I have gone through thousands of posts and links over the last couple of weeks and tried every single one to no avail and it would seem that all the 'advice' is from people that have never done it in sierra. The advice may work in windoze or Linux, but not under OSX.

Basically, mysql seems to ignore any "my.cnf" file in any location.

One would think this an easy task, but apparently not.

Using MySQL Installer MSI -> freezes up on Check Requirements - MS Visual C++ 2013 runtime 64 bit not installed.
2013 is no longer available -> installed of 2015 = same results. Installed of 2010 = same results.

Attempted manual install -> get stuck at running mysqld at CMD line. I get, Program cannot start because MSVCR120.dll missing. -> did sfc /scannow no corrupt or missing files.

Also, can someone recommend a forum that doesn't harass users with so-called spam prevention codes. I can hardly read these and I'm not even a robot.

My question: Unfortunately a co-worker has switched the website to PDO instead of MYSQLI. I cannot get PDO to work on my localhost computer though so this causes development problems since I have to develop using mysqli but then place it on a PDO site. I could use some sort of guide to getting this to work. Oddly it works fine with CakePHP, but the site is CodeIgnitor 3.

Greetings,

I need to install MySQL into '/mysql' folder instead of '/usr' onto HP-UX 11.31. For your information, the format for the MySQL that I downloaded was in depot files form. My question is how to change the installation path since MySQL already been prefixed to automatically installed onto '/usr'?

Thank you in advance for your reply.

I have MySQL installed and running under Windows 10 as a localhost. I have repeatedly set the Startup Type in Services to Automatic, and it keeps reverting to Manual. Sometimes, it will revert to Manual on the very next startup, other times it will last for two or three reboots before reverting. I realize that this is likely a problem in the interface between Windows 10 and MySQL, but it's unlikely that Microsoft will even acknowledge the issue. Has anyone else encountered the issue and, if so, figured out a way to fix it?

Apparently I installed MySQL on my machine before. Well I uninstalled all components from the control panel and tried to install ver 5.7. I am in the InnoDB Sandbox Cluster Phase of the install and I am getting this message:
An existing InnoDB Sandbox Cluster seems to have been previously created. The sandbox cluster instances that are running need to be stopped for the configuration to be performed correctly.

How do I stop the InnoDB Sandbox Cluster?

Hi everyone.


I'm Oracle DBA and new with MySql. I'm suffering a little bit with MySql.

So, help me please.

Look, last week I had installed the last version of MySql 5.7.18 on my linux server. I followed the documentation. The installation were fine and also the steps to secure installation using mysql_secure_installation.

So, today I went to login in mysql using command bellow I got the following error:

[root@inimysd01 ~]# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@inimysd01 ~]#

I can't get the correct solution for this error until now. Could you show me where I'm wrong.

Or could you explain me the correct steps that I need to do.

Thank you very much.

i have a strange issue on a web server (Windows Server 2012) with MySQL 5.7.16. Root lost privileges, i don't know why.

If i type mysql -uroot -ppassword appear an error (root@127.0.01) Access Denied using password YES

I tried to use another user with all privileges and i've seen that in host there is only localhost (not 127.0.0.1)


How can i login with root@localhost and not with root@127.0.0.1? It's very frustrating... Every account trying to use @127.0.0.1 or @::1 but there exist only localhost in host and i can't change it.


So i don't know how to fix it.

Hi,

This is the first time I install MySQL and when I tried to enter by the Terminal. I just type this "/usr/local/mysql/bin/mysql –u root –p". Normally, I think it supposed to ask me my password. This is what appeared. Thanks in advance for the answer.

First of all, I am a Linux administrator with a very strong network engineering background, so I am not even a MySQL newbie.

I have a database that was created under MySQL 5.5.34 Community Edition. I need to have the server upgraded to the latest MySQL. Is it possible to take the exported database and import it into a MySQL server running the latest version?

Respectfully,

James

Once again I wanted to install MySQL on another computer with Win7 64bit.

I downloaded the most recent *.zip archive of the community server and extracted it. Much to my surprise I could not start it. Even a simple "mysqld.exe -version" call was rejected with an error prompt:

"The application was unable to start correctly (0x000007b). Click OK to close application."

So what?

No further information was given. Even event log shows no hint.

After comprehensive investigations I found out that the
Visual C++ Redistributable Packages for Visual Studio 2013 64bit
was missing. After installation it works.

The MySQL error however is absolutely useless and misleading.

There should be a self-check at startup and a meaningful error message if the Visual C++ lib is not available on the current computer.

Hi,

I installed MySQL 5.7.19 (yum install) on my RHEL 6 server.
I followed the instructions from this page:
https://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html

At step 4 - Checking the temporary password "shell> sudo grep 'temporary password' /var/log/mysqld.log", i'm blocked as there's no line saying that there's a temporary password.

Here is the log after having installed and run MySQL server (port 3306 has well arised)

so i thought that root user came without any password and i tried to enter mysql or mysqladmin (mysql -uroot) and i still got the message:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

Please, could tell me what's wrong ?
Any idea on where should I look at ?
