I'm trying to delete msyql 5.1 and install mysql 5.7 on Centos 6.9 However when I enter
"yum remove mysql-libs-5.1.73-8.el6_8.x86_64"
it shows a whole slew of applications such as crontab, chrome, redhat-lsb-core, postfix and many others that will be deleted because they have a dependency on it.
From googling, I saw there is a "swap" option, but can I do this for each application? Do both the old and the new MySql libraries have to be installed?
Another option is to leave the old dependency there, and install the new one. But it seems like this could throw off the mysql install...it might somehow find the old dependency - or the existing apps might find the new dependency.
A third option is to re-install all the deleted applications, but figuring out how to install mysql was tricky enough. How do I know which ones are critical or not, for one thing? I definitely need crontab and chrome. The other "redhat-lsb" onese look important. Also postfix.
Any ideas on how to approach this?
To avoid issues such as this, CentOS/Redhat has provided another way to get latest packages of MySQL, PHP, Python etc.. through Software Collections(SCL).
Using SCL you can have multiple versions of MySQL running on the same server without any conflict or dealing with dependency.

I've got a client that's running a pretty ancient version of Mediawiki (1.17.0) on an internal corporate network. It's running on PHP5, but they're looking to upgrade to PHP7. This version has basically served its purpose well and whoever was in charge never messed with upgrading it. (I know) But it won't run under PHP 7.4 and the company is upgrading their PHP systems.
Obviously there have been a TON of revisions to MediaWiki in this time. I've got a few questions...
First, what's the earliest version of MediaWiki that is PHP7 compatible?
Second, what's the best approach to updating this system? It's got over 1000 pages and 1000 images. It's not huge, but it's obviously not small, and if there's any way to automate bringing this up to the most current version, I'm curious what my options are?
I'm trying to avoid doing incremental updates because upon investigating, it's a ton of them, and not all interim versions seem to be available.
Is it possible to install a new, fresh version and copy the database/images over?
Any advice is most appreciated!
As noted in https://www.mediawiki.org/wiki/Compatibility#Upgrade , you need to upgrade first to 1.35 and then to 1.38 (or 1.39 if you wait a little - 1.39 is an LTS release so probably worth it). See the manual on upgrading on how to do it - basically, update the files in MediaWiki core and all extensions, possibly run composer update depending on your distribution (tarballs tipically already include the files that Composer would download, git doesn't), and run the upgrade script wich will migrate the DB.
I would like to install different MySQL versions on Windows. I have a MySQL 5.5 running, and I want to install a MySQL 5.7 to debug compatibility issues of a program I am working on. Both installations should stay side at a side, may have their own databases (it’s OK to start with an empty 5.7) and I am happy to run or stop the one or other from the Services control panel manually. The nowadays MySQL installer - community wants to upgrade my existing installation and, unlike explained in this article, does not offer another option to install the versions side to side. All I found was a rant confirming my problem, but no real solution. If it requires me to install it manually, I need detailed instructions. In my case, default setup (default port) is sufficient, because I don’t need to run both instances the same time.
This is not so obvious but using the "MySQL installer", you need to run it, then click on "Cancel" and a new window will appear, letting you install new elements. You can then select the version(s) of MySQL that you want to add to your system.
You don't need it but if people want to run several instances at the same time, they need to choose a different port for each installation.
Why not simply use a virtual machines to install your different MySQL version ?
Like that you will be sure to have no compatibilty issues between them and you can start/stop vms as you like.
Otherwise, I did find that : https://www.codementor.io/arpitbhayani/setup-multiple-mysql-servers-with-different-versions-docker-du107solq but can't confirm it's working.
Use Dockerized mysql and you can run as many mysql versions you want on different ports.
I have a LAMP server on an EC2 instance. I downloaded phpMyAdmin using Amazon's guide here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html.
On the phpMyAdmin page it says that:
"A newer version of phpMyAdmin is available and you should consider upgrading. The newest version is 4.6.5.2, released on 2016-12-05."
and I need to update it and also MySQL to use new features they put on the updates.
I'm accessing the EC2 instance from the terminal in my Mac laptop. I've tried a lot of things but I couldn't manage it. I've tried
sudo yum install -y phpMyAdmin
sudo yum install
I tried to manually download the latest version from phpmyadmin.net and change the files in the folder but I couldn't access the phpmyadmin folder in the first place.
Any help would be appreciated,
Thanks
You're using the version of phpMyAdmin maintained by your distribution (presumably Fedora, CentOS, or Red Hat); this means that basically you're not responsible for (or able to) upgrade the software that's under control of the package manager (aside from running the updates occasionally). If you wish to use a different version, you're certainly able to remove the package manager version then install it manually. I don't use EPEL, but I believe the highest version currently distributed is 4.4.15.9 (reference, which I think is because of the older versions of PHP and/or MySQL which are currently shipped. So you might not be able to upgrade due to your MySQL or PHP versions, but YMMV.
Basically, if you're using the package managed version, the whole point is so you don't have to worry about manual updates.
You can disable the notification by adding the directive $cfg['VersionCheck'] = false; to your config.inc.php (which may be in /etc/ or /etc/phpmyadmin, but I'm just guessing about how your distribution may handle it.).
I want to install MySQL installer msi with my setup.(MySQL installer has to install silently. I am using batch file in custom action to do this.)
However, the problem is that MySQL's msi cannot be run from within main setup.msi it gives out 1618 error(Another installation needs to be completed.) I would like to know an easy way around this.
Background info: MySQL installer unpacks the manifest which contains MySQLInstallerConsole.exe it is then called through another cmd command to install MySQL.
So all I am looking to do is to execute MySQL installer so that it unpacks the manifest. Later I would call the MySQLInstallerConsole.exe to install MySQL through custom action.
Just to mention even more possibilities- some my colleagues mentioned (VS bootstrapper, burn):
Just start writing a batch or script for calling the two MSIs after each other.
Always a good starting point maybe, if you have no experience with MSI.
Write your own mini setup.exe bootstrapper with 5 lines of code to do the above.
(To be more concrete in "Third party tools":) Buy InstallShield or Advanced Installer or InstallAware, this are the tools with ready GUIs to do such easy bootstrapping.
I would recommend the second out of them. Starting another MSI are only two clicks. Similar with the other. But there are BIG differences between the three, especially InstallAware is special.
! Mentioned "mini bootstrappers" of those tools are not as powerful as Burn or the others followed:
Buy the ready setup suite SetupFactory which can be used as a bootstrapper for MSIs.
Use the InstallShield "Suite" project type, if you buy the Premium Edition of InstallShield. Costs big bucks, but has a friendly user interface. I was successful using it before some years, but I had to work around a handful of bugs as always with IS (but I guess you will discover bugs with most tools. Way it is.)
There (again) Burn would come in handy, you could fix potential bugs or behaviours on your own here ...
Only it could take you more time in the beginning.
... Of course there may be more.
There isn't an easy work around. Windows Installer enforces a 1 installation at a time rule through the use of a mutex. You need to create a bootstrapper / chainer to serialize the installation of your packages. Visual Studio Deployment Projects don't support this. I'd suggest looking at Windows Installer XML (WiX) and it's Burn boostrapper / chainer engine.
The documentation is a bit sparse, but in the Visual Studio world the customized bootstrap is the Bootstrap Manifest Generator. The docs start here:
https://msdn.microsoft.com/en-us/library/ms165429.aspx
and there is an old article here:
https://msdn.microsoft.com/en-us/magazine/cc163899.aspx
but it's not clear how much info and support is available since setup projects were removed from setup projects and then restored.
I need to read a database table from inside a Lua script in pdns-recursor on a Scientific Linux 6.4 server which comes with Lua pre-loaded.
Apparently I have to use luarocks to install luasql. When I attempt to install luasql I get:
Checking Lua includes... lua.h not found
lua.h is not on the server.
I tried removing the installed version so I could install from binary but then that trashed the system which apparently uses the installed Lua for everything (yum, rpm, etc). Now I have to reload OS. How can I get MySQL access from embedded Lua?
Thanks in advance.
I assume that you have already checked yum to see if luasql is available through that; if not, you should first do that, and install it through yum if possible.
The immediate cause of the problem you're having is that luarocks automatically builds modules from source, which requires access to the lua headers. These are not needed simply to run programs that use Lua, so they are not installed as part of the normal Lua package. I'm not familiar with Scientific Linux, but you can probably get them by installing a package named lua-dev, lua-devel, lua-headers, or some variant thereof. You may also need the mySQL packages (both the libraries proper and the headers). Once you have those installed, give it another try.
You might also try LuaDist, which I find to be generally more polished than luarocks, and capable of automatically downloading more dependencies; in particular it probably will not require the lua headers installed, and can handle automatically downloading and installing lua itself from source. It does, however, require CMake installed.
If for some reason you can't install the required headers and can't get luarocks or luadist working, you can try downloading and building luaSQL by hand. The Lua headers can be found in the Lua 5.1 source package and LuaSQL 2.2. Assuming the Scientific Linux maintainers haven't excessively customized the version of lua they ship with it, the results should be compatible with the system Lua install.
