Hi

I have just installed MySQL and want to use it for (research) software development. I have a few computers where I do software development and I wannt all those machines to be able to access the database(s).

If I just had one machine, it would be a no brainer and I would just use localhost, as nobody else needs to access the data.

I just can't decide where best place to locate the data files. The options I am considering (but happy to hear other views) are:

1) Just store on the local machine and let Dropbox take care of syncing the data.
Downsides: The data might get quite large and blow my storage capacity
It could take a long time to sync.
Upsides: Access should be quick as I am just using localhost

2) Use a Network Storage device (I have a Synology untit)
Downsides: Access might be slow as I have to go "over the internet"
I'd still like to sync with Dropbox just"to be sure"
Upsides: Sapce shoud not be an issue

3) I have my own domain registered so I could use that
Downsides: Not sure how I could connect, and not sure of the secuity implications.
Backing up is an issue?
Access times might be significant, when compared to localhost?
Upsides: The availability of the "data storage" is being managed by a professional company

4) Use a cloud based service.
Downsides: Note sure how these work, the costs and the backup options.
Are access times a factor when compared to localhost?

You might ask why I want to use mySQL. It's because in the future, I might want to do a PHP roll out and MySQL seems the way to go. Also, I want to "force" myself to think about the structure of my data.

Thx

I am trying to install MySQl v.5.6.17.0 server on windows7 but the Connector ODBC 5.3.2 will not download.
Do I have to download it separately? And how do I connect it?

Any further information would be appreciated.

≪ Previous: Plugin 'FEDERATED' is disabled. (no replies)

Beginning with a working installation of 5.6 on Windows 8.1, I thought I'd take a look at MySQL for Excel. With the installer I selected only MySQL for Excel and installed. A short experiment showed that it did not do what I needed so I uninstalled it.

The next time I went to use Workbench no connection to the server was available - the server was stopped. Attempts to start the server resulted in the following:

"The MySQL56 service failed to start due to the following error:
The system cannot find the file specified."

There was no indication of what file could not be found. From there I uninstalled all MySQL related applications (server, workbench, ODBC connector, etc.), rebooted and reinstalled.

During configuration I'm prompted for old and new root passwords. Regardless of whether the old password is provided I get an error that I could not connect, so installation fails. Event viewer provides the following:

"The description for Event ID 100 from source MySQL cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

Now what?

On my CentOS 6.4 server, I am running MySQL 5.5.33 that I installed from the remi repository (http://rpms.famillecollet.com/).

I decided to upgrade MySQL to 5.6.x via MySQL's own yum repositories. After installing the repositories per these instructions:

http://dev.mysql.com/doc/mysql-repo-excerpt/5.6/en/linux-installation-yum-repo.html

My enabled repolist looks like this:

# yum repolist enabled
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* Webmin: download.webmin.com
* base: mirrors.xmission.com
* epel: mirror.steadfast.net
* extras: mirror.thelinuxfix.com
* remi: remi.check-update.co.uk
* updates: mirrors.xmission.com
repo id repo name status
Webmin Webmin Distribution Neutral 175
base CentOS-6 - Base 6,367
epel Extra Packages for Enterprise Linux 6 - x86_64 10,737
extras CentOS-6 - Extras 14
mysql-connectors-community MySQL Connectors Community 6
mysql-tools-community MySQL Tools Community 6
mysql56-community MySQL 5.6 Community Server 46
remi Les RPM de remi pour Enterprise Linux 6 - x86_64 1,485
updates CentOS-6 - Updates 864
repolist: 19,700

So the MySQL 5.6 repository is installed and enabled. Now if I try to check the info of the installed MySQL to see what the latest version is available, I get this:

# yum list mysql-server
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* Webmin: download.webmin.com
* base: mirrors.xmission.com
* epel: mirror.steadfast.net
* extras: mirror.thelinuxfix.com
* remi: remi.check-update.co.uk
* updates: mirrors.xmission.com
Installed Packages
mysql-server.x86_64 5.5.33-1.el6.remi @remi
Available Packages
mysql-server.x86_64 5.5.37-1.el6.remi remi

So it's looking in the remi repository for the latest version which is not 5.6. So I disable all other repositories except for mysql56-community and I try this:

# yum list mysql-server --disablerepo=\* --enablerepo=mysql56-community
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
Installed Packages
mysql-server.x86_64 5.5.33-1.el6.remi @remi

It finds my current version, but not other versions available. Why isn't it finding a version available on the mysql56-community repo?

However, if I instead search for mysql-community-server:

# yum list mysql-community-server --disablerepo=\* --enablerepo=mysql56-community
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
Available Packages
mysql-community-server.x86_64 5.6.17-4.el6 mysql56-community

Then it finds the correct one from the mysql56-community repository.

So my question, why isn't it finding the latest 5.6 version of mysql-server ? What do I do here? I don't know exactly how yum works, but I'm assuming that updating mysql-server will update all it's subpackages as well. And if I just install mysql-community-server, will there be a conflict with mysql-server?

I'm a bit lost here on what to do or how to get MySQL updated to 5.6.x

innodb_large_prefix and ERROR 1709 (HY000): Index column size too large. The maximum column size is 767 bytes. (1 reply)

May 1, 2014, 5:24 pm

Hi,

I recently installed a product that uses MySQL in the backend but it failed to install when building an index due to the following error:

ERROR 1709 (HY000): Index column size too large. The maximum column size is 767 bytes.

The OS is CentOS 6.5 and I have tried on Oracle MySQL 5.5 and 5.6. The mysql and product DBs are using character set UTF8.

Reading the documentation, querying the database and googling I find that MySQL UTF8 can use up to three (3) byes per character. The table column for the product had been defined as NAME VARCHAR(256), so indexing on it would consume 768 bytes (one too many for the prefix_length and hence the error).

Ok, so I can define the column as NAME VARCHAR(255) or create the index as NAME(255) and all is good.

I also read that, if set, innodb_large_prefix allows larger prefixes (up to 3072 bytes) so I thought I'd try that instead of hacking the product's database creation scripts.

I can't get that to work! I have tried setting innodb_large_prefix but it has no affect on the index creation. On a column larger than VARCHAR(255) it still issues the error:

ERROR 1709 (HY000): Index column size too large. The maximum column size is 767 bytes.

I have set (as per the doco http://dev.mysql.com/doc/refman/5.5/en/innodb-parameters.html#sysvar_innodb_large_prefix):

innodb_large_prefix | ON
innodb_file_format | Barracuda
innodb_file_format_check | ON
innodb_file_format_max | Barracuda
innodb_file_per_table | ON

SHOW TABLE STATUS indicates that the row_format for the table that defines the column I'm attempting to index is 'Compact'. Does that mean the same as Compressed?

My question is, how can I use the innodb_large_prefix option? Does this apply to VARCHAR or only to another column type?

Kind regards,
Tom
