percona-server | Percona Server for MySQL

mysql@bootstrap needs to be executed on only one node. The other node do a normal start and then it will SST off the first node.

With two nodes you will have trouble getting a quorum and its unworkable as a HA system.

• Trynode -v to see whether you've installed node. I think your node not works.

• nvm is the environment managment for node. If you are using nvm, you should brew install nvm, and use nvm install version-of-node-you-want-to-install to install node, and use nvm use the-version to let node works.

• Whole install chain is:

  • brew install nvm, to install nvm, which is environment/version management for node.

  • nvm install 10.3.0, to install node and npm

  • npm install -g yarn, to install yarn

  • use node -v, npm -v, nvm -v, yarn -v to check if they all works.

I've tried to replicate your issue on my test project and found that:

• persistent disk was created and mounted in read-write mode as expected;

Solution: remove the installation folder directly. It's totally safe.

brew cleanup requires the latest version to be installed. This is reported in issue 412. But not any improvement has been done.

What is the reason behind disallowing the cleanup of older versions of formulas when the most recent is not installed?

Technically, Homebrew doesn't consider a formula to be installed unless the latest version it knows of is installed. And because only installed formulae (in the sense I explained here) are checked for older versions that could be cleaned up, this isn't happening.

unfortunately, you have run into a known issue here, and you are right it is to do with the perl-DBD-MySQL package

You should be able to remedy this by running this

mysql is already uninstalled. See these lines in the middle of your output:

After a lot of work I was able to find the culprit. MySQL 8.0.11 is not stable enough and breaks several of my gems.

In the end it was enough to:

$ brew info mysql (to get info about the installed versions)

$ brew switch mysql 5.7.21 (to switch to a stable version)

Now the server, the mysql gems as well as DB connections are working again…

There was no need to uninstall mysql 8 in my case.

Copying Laurynas's answer here so this question can be marked "answered": This is best asked on bugs.mysql.com/bug.php?id=67906 (note that Percona patch cannot be taken MySQL directly due to their contribution rules). – Laurynas Biveinis

Open the terminal and run the following command:

apt-get install apt-transport-https lsb-release ca-certificates

Get the gpg key:

wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

Add the new repository to your sources:

echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list

Install PHP5.6

apt-get update apt-get install php5.6

Update

Workaround for line echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list:

Run this, and take note of the output:

lsb_release -sc

Open up /etc/apt/sources.list.d/php.list in your editor of choice and append this to the bottom:

deb https://packages.sury.org/php/ OUTPUT_FROM_LSC_COMMAND main
