Hi all,

I have a question about MySQL in Centos 6.7 server, please you help me

Mysql server is a error "can't connect server through socket "/var/lib/mysql/mysql.sock", I didn't found that file. I resolved this error by created a mysql.sock file with empty data in there, and restart mysql normal.

Now, let me ask this error occurs again in the future and when happened?

Many thank you all,

I downloaded and installed mysql-5.7.16-osx10.11-x86_64.dmg

The first time I clicked on the 'Starty MySQL Server' button and entered my password, the system came back with an error message: 'Could not startup MySQL Server. Reason: 255'

I reinstalled mysql-5.7.16-osx10.11-x86_64.dmg

Now when I click on 'Start MySQL Server' in the Preference pane and enter my password, the procedure does what it does before asking me for my password again 5 minutes later. This continues at exactly 5 minute intervals. I've done that for 10 iterations now. Make that 11 times now...

Any advice? Suggestions?

Hi All,

I just want to say that I am new to mysql and have searched the internet for the answers before posting, but have not been successful.
Here is what I am trying to do:
2 hosts, with the possiblity of more in the future. I want to run a cluster by having 1 host with mysql server, data node, and management node. The second will have a data node and mysql server.
I would like to know first if I need to install the mysql server separately from the cluster?
Second, every site I visit has a different command for starting the nodes in the cluster...is there some where that has them with explaination? I know the mysql site has a tutorial, but when I use those commands, it doesn't seem to start.

Thanks in advance!

Hi.

I have installed MySQL 5.7 onto Ubuntu 16.04. I have tried to move the datadir using the following instructions.

- sudo /etc/init.d/mysql stop
- sudo cp -R -p /var/lib/mysql /data/mysql/data
- edit /etc/MySQL/my.cnf. change datadir to /data/mysql/data
- sudo pico /etc/apparmor.d/tunables/alias and add the line...
alias /var/lib/mysql/ -> /data/mysql/data/,
- sudo /etc/init.d/apparmor reload
- sudo rm -rf /var/lib/mysql
- sudo /etc/init.d/mysql start

I have also tried editing /etc/apparmor.d/local/usr.sbin.mysqld, changing /var/lib/mysql to /data/MySQL/data and restarting apparmor.

Also, folder permissions look correct as mysql is the owner of /data/mysql/data.

Any help would be appreciated. Have spent days trying to figure out why it still wants /var/lib/mysql.

Thanks.

Hello MySQL users,

Does MySQL provide patches to manage the leap second that occurs at the end of the year or is something that doesn't affect MySQL at all, is it more like a OS level kind of issue?

Thank you.

≪ Previous: Cant install MySql because the digital signature is invalid? (no replies)

I've been trying to get motivated enough to start a personal project that will hopefully teach me enough to where I can take what I have created, and use it as a skill set when looking for side work setting up small databases' for small office environments requiring sharing data for reports and inventory management or even project management.

I would like to setup a MySQL database on my hosted domain and also install the same database on a client computers or laptops which will sync with the online database, thus keeping all the data current across all client machines via internet connection.

I have my own, one man computer business and keeping track of what I do is a nightmare. I did set up a rather large MS ACCESS database and its nice, however, i need access to it while I'm mobile so I can just update information live while I'm working--this seems impossible. I would like to build a customer database with all my clients and the jobs I do, parts I buy and my expenses and be able to just boot my LINUX laptop and update my job information locally while I'm working and be done with it. I should be able to go to any web browser and log into it from any computer OR have a copy of the database on my laptop always available with the ability to sync with the online data....

Quickbooks and Quicken....and even any basic email client such asThundrbird all can do this....

I want my own database to do the same thing....why is this such a guarded top secret issue.....only seems like its common sense that people would want a wizard that would step through setting this up, with VPN and certs and all...

Of course this would have a PHP built UI

am I crazy for wanting this...

Thanks guys..

Hello,

I have several schemas created with the MySQL version that was installed on my laptop before I had the Windows 10 crash. It was MySQL 5.1.73 probably, because I still have its MSI installer in my HD.

I have installed MySQL 5.7 Community version and I would like to change the driver and folder where MySQL data is saved to and bring those old schemas to the new installation.

I have no any MySQL backup, is that possible ? If I change my.ini and set datadir to the old datadir folder the MySQL service fail to start.

I installed MySQL 5.7.17 Community on Windows 10.
Used the sequence described in the Ref Manual in 2.11.1 Upgrading MySQL and the section titled Performing a Logical Upgrade. Also followed several cross-references in that section.

1- Reviewed 2.11.1
2- Used MySQLDump to offload my data.
3- Shut down server.
Removed the software using Windows functions. Removed old folders on hard drive.
4- Installed with the MySQL Installer.
5- Skipped initialize data directory. Section 2.3.7 says Installer does it.
6- Start server with mysqld_safe - ERROR mysqld_safe not recognized
So rebooted to start server.
7- Reset root password. The one I set during install was OK, so I skipped this.
8- Reloaded data. All OK. USED THE ROOT PASSWORD HERE.
9- Ran mysql_upgrade. Two messages but all went OK.
10 Shutdown and re-start. Re-booted (as mysqld_safe no good).

Tried to start mysql to define USERS and GRANTS and I got the ACCESS DENIED error.
Why did it work to reload the data and not here? What have I missed?

Have just updated from 5.5 to 5.7.17.

Every time one of my Java programs issues a Select or Update to MySQL, I get a long-winded WARN message:
Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

While I understand the idea of the message, the "fixes" are above my technical prowess.

1) Where do I set the parameter "useSSL=false"? I tried putting it in my.ini but got errors from MySQL that it was an invalid parameter.
2) This is a system where all users come in through Remote Desktop Connection. If I do set useSSL=false are there security concerns?

Thank you.

hello,

I'm new to MySQL and databases. I'm trying to get to grips with the deeper structure and I'm confused about why there are apparently two locations after installing MySQL and I was hoping someone could clarify what each is for?

I have this:

/usr/local/mysql-5.7.17-macos10.12-x86_64/

and this:

/usr/local/mysql/

Why are there two mySQL related directories in the local folder? In terminal access the database by doing this to login: cd ./usr/local/mysql/bin and then typing: mysql -u root -p 'password'.

However if the database is stored in the data folder and everything apparently seems to be happening in the /usr/local/mysql folder, what is this for:/usr/local/mysql-5.7.17-macos10.12-x86_64/

It's been bugging me for a day now and I've not been able to find anything online other than the bottom of this URL: https://dev.mysql.com/doc/refman/5.6/en/osx-installation-pkg.html

I am attempting to do an in-place upgrade for MySQL server from 5.6.31 to 5.7.14.
I have with me .msi files for 5.7.14 and 5.6.35
when I execute the .msi files it detects the previously installed version of the server and provides me options to remove, upgrade etc.
When I attempt to upgrade from 5.6. to 5.6.35, through the .msi file of 5.6.35 it happens seamlessly, whereas for 5.7.14 I am confronted with a message stating "none of the products have upgrades available".
http://dev.mysql.com/doc/refman/5.7/en/upgrading.html - in this link it clearly states that "Upgrading one release level is supported."

The .msi for 5.7.14's server is present in "C:\ProgramData\MySQL\MySQL Installer for Windows\Product Cache" folder at the time when I attempt to upgrade. then why is it giving me the error message?

Can you please help me do an in-place upgrade, up a release level, without having to uninstall the existing version and reinstalling the new one (without loosing the existing database)?
