![]() Interaction is required when you install the MySQL server. Non-Interactive Installation of MySQL Server 8.0 At the end of the post you have the full playbook in which we do it all using Ansible. The above commands can be easily scripted, and no interaction is needed. The other way is to simple create the file /etc/apt//mysql8.list: echo "deb $(lsb_release -sc) mysql-8.0" | \ You could use add-apt-repository, but it would mean installing yet again more dependencies. # Note: key 5072E1F5 is MySQL official's (always double check!) Sudo apt-key adv -keyserver -recv-keys 5072E1F5 In the following steps, we do not download the mysql-apt-repo package, instead we do whatever it does, manually: sudo apt install -y dirmngr The following is inspired by the MySQL Documentation under A Quick Guide to Using the MySQL APT Repository and Adding and Configuring the MySQL APT Repository Manually. First, Set Up Official MySQL APT Repository You need the “legacy” plugin which can be set globally in the configuration or, more preferably, when creating the database user. If you are using Go, the new default authentication of MySQL 8.0 does not work yet. Whether that is a documetation bug is open for discussion. The first two screens are not new the 3rd is, and it is not documented. There are currently two interactive questions being asked: Especially with Group Replication, where you need a minimal of 3 servers. Installing a single MySQL server is easy, but once you have done it, the fun starts to fade after a dozen or so times doing it. You can also do such unattended installs for each application. It also shows the extra step to keep using the legacy MySQL authentencation method.īonus: Ansible playbook included! Unattended Debian Installationĭebian comes with debconf which can be used to do install the whole distribtion non-interactively without a (virtual) monitor attached. This post will show how to install MySQL 8.0 on a Debian 9 using the official MSQL APT repositories. If you start new, and you can, stick to the new method. If you are using a MySQL driver which has no support yet for strong password encryption (for example the go-sql-driver/mysql package driver), or you “need” to switch to MySQL 8.0 and keep previous user accounts intact, you will want to set the default back to the mysql_native_plugin for authentication. The missing part is the extra question during the installation of the server whether you want to keep using the new default authentention method, or use the (now) legacy native method. One of the stacks we are enrolling is MySQL Group Replication, which requires at least 3 servers.Īlthough the MySQL Documentation show how to install MySQL non-interactively, it is not entirely complete. To make things easier and automated, we can use the non-interactive feature of the Debian packaging system to deploy services. > If we knew what the terminology really meant we wouldn't need to learn anything.At work we are doing quite a bit with Debian. There's a group there I'm sure you could learn a lot with. If you really want to learn more about this, this is the best book on the market, Grady Booch was the father of UML Re: three-tier architecture - adding security to your applications Re: MySQL Functions in the url php dot net/manual/en/ref dot pdo-mysql dot php Interface to datalayer to database, datalayer to database to datalayer to interface.īy implementing best practices while writing your code you will be much happier with the outcome. By using this intermediary layer that is the ONLY 'player' who talks to the database itself, I'm sure you can see how this could be much more secure. You can also harden your site to SQL injection by using a data-layer. he gets seven points, because he got it there and did so much more securely than passing information through the URL. User interface hands off the ball to the PDO which carries it down field and plants it into the database for a 7-point TOUCHDOWN. Using the PDO, all of this is done under the user interface level. (Capitals are Capitals, no leading or trailing spaces, all dates at properly formed.)īut there are a few nuances to this which you might not be aware of.įirst of all, up until now, you've probably written all your queries in something similar to the URL, and you pass the parameters using the URL itself. By using this layer, data can be normalized before being inserted into your data structure. The purpose of using this is to implement an additional layer of security between the user interface and the database. PDO_MYSQL is the driver that will implement the interface between the dataobject(database) and the user input (a layer under the user interface called "code behind") accessing your data object, the MySQL database.
