在 Ubuntu 18.04 上安装 MySQL 客户端 5.6

Question

I have a legacy project that I'm trying to modernize, and part of that involves setting up a more efficient system of automated backups using mysqldump .

The app's database is using MySQL 5.6, and is hosted via an RDS instance. To get mysqldump up and running, I believe I need to install a version of mysql-client that corresponds to 5.6.

However, running apt-get install mysql-client installs 8.0 by default. However, I can't find any version-specific versions of mysql-client available. Running sudo apt-get install mysql-client-5.7 returns a notice that there's no installation candidate available.

Is it still possible to install older versions of mysql-client ? If not, is there another way to get ahold of the mysqldump functionality?

Edit: As @exussum noted below, 8.0 is backwards compatible with 5.6 and 5.7. I was hitting errors when running mysqldump , which I'd assumed indicated incompatibility, but were actually related to my app specifically.

Answer 1

They are backwards compatible, so you can use mysql-client 8 to dump mysql-server 5.5

to get a specific version docker is great

( sudo apt install docker ) to install

docker run mysql:5.6 mysqldump

will run mysqldump though docker, and you can choose your version there easily enough
