If you want to have a look on what is about to come in the new version of the popular database and is used to Syntax Highlighting you don’t need to be chained to the Terminal.
Some of you may use tools like MySQL Workbench or Sequel Pro (as of the release of this post both tools had the following error occurring), and even if you are using the Terminal (if you are using an old version of mysql
, like 5.7) you may encounter this error:
Unable to connect to host 127.0.0.1, or the request timed out.
Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).
MySQL said: Authentication plugin ‘caching_sha2_password’ cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 2): image not found
The reason for that is because since the 8.0.4 RC release, MySQL now uses SHA-2 Pluggable Authentication. In another words, how the database does authentication now changed.
Graphical User Interface
As of now, the only tool I could verify that it is working is Datagrip. But there is some steps to make sure you can successfully connect to the server. Follow the steps
1. The JDBC Connector
- Open the JDBC Connector page. Click on “Development Releases” tab and select your operating system, as of this post 8.0.9 was the latest version.
- Select the
zip
version of the file, if you are using macOS, select “Platform Independent”. - The website it will ask for you to login, you don’t need to login, there is a link on the bottom of the page that says: “No thanks, just start my download.”.
- Unzip the
zip
filemysql-connector-java-8.0.9-rc.zip
(the name may be different for you if the version is different) - A folder will be created with the name of the compressed file, inside copy the
jar
file to a location where you can access it later easily, for example, I put mine in~/workspace/drivers
folder.
2. The GUI configuration
- Open Datagrip. Go to “File > Data Sources“. A window will open, right click on top of the “MySQL” name and select Duplicate.
- A new Driver is added with the name “MySQL [2]”, rename it to “MySQL 8.0”
- Then, unselect “Use” on “Driver Files” and click on the
+
sign. Select thejar
file you downloaded on the previous section.
- Click in Apply.
J’ai arreté d’utiliser MysqlWorkbench parce qu’il crash avec les tables mariadb contenant des champs json.
Je suis passé à DBeaver et franchement j’y retrouve sous linux, le confor que j’avais avec SqlYog.
I stopped using MysqlWorkbench because it crashed with mariadb tables containing json fields.
I switched to DBeaver and frankly I found, in linux environment, the confor I had with SqlYog (but windows only).

In addition to what you have said, if anyone test connection and didn’t work, try changing these two variables:
When creating a Project using MySQL 8.0 (ready to test connection), go to advanced tab,
change
defaultAuthenticationPlugin to: com.mysql.cj.mysqla.authentication.CachingSha2PasswordPlugin
zeroDateTimeBehavior to: CONVERT_TO_NULL
fixed my problem.

I forgot to mention I was using the EAP version, not Datagrip stable one, maybe that is why I didn’t hit any of these issues 🙂

Hello Gaby, I am trying to do the same trick in PyCharm 2017.3, but I am getting the “Could not create connection to database server. Attempted reconnect 3 times. Giving up” error message, do you have any ideas?

I used Sequel Pro to connect to MySQL 8 and after running a few queries, it crashed. That happened quite frequent so I looked for another tool. I never tried DataGrip but I found TablePlus. It’s a great GUI tool that works well with MySQL 8 and also supports a handful list of other popular relational databases. The design is pretty intuitive. I think you should check it out too 🙂
