使用Chef在CentOS上安装MySQL Community Server

Question

I try to install MySQL Community Server on CentOS7 using Chef mysql cookbook from supermarket: https://supermarket.chef.io/cookbooks/mysql

My cookbook files:

metadata.rb

depends 'mysql', '~> 8.0.4'

default.rb

mysql_service 'db_some_data' do
  port '3306'
  version '5.7'
  initial_root_password 'abc123'
  action [:create, :start]
end

I executed:

berks install
kitchen test -d never

and got following error:

================================================================================
Error executing action `install` on resource 'yum_package[mysql-community-server]'
================================================================================

Chef::Exceptions::Package

     22:         action :install
     23:       end
     24:

It looks like this issue: https://github.com/chef-cookbooks/mysql/issues/443

Thanks for your time!

Answer 1

I suspect you may need to use a different cookbook for this as the command below doesn't show mysql-community-server in the centos 7 repo. Perhaps try the mariadb cookbook.

yum provides mysql*

However if you really have to install mysql-community-server, you probably need to modify your recipe to look like so

execute 'mysql-community-repo' do
 command 'yum localinstall https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
 action :run
end

 mysql_service 'db_some_data' do
  port '3306'
  version '5.7'
  initial_root_password 'abc123'
  action [:create, :start]
 end   

Keep in mind, you may encounter some issues with the systemctl init script when starting mysql-community.

Answer 2

I managed to fix this setup with following changes:

metadata.rb

depends 'mysql'
depends 'mysql2_chef_gem'
depends 'database'

default.rb

mysql_client 'default' do
  action :create
end

mysql_service 'db_some_data' do
  port '3306'
  version '5.7'
  initial_root_password 'abc123'
  action [:create, :start]
end

mysql2_chef_gem 'default' do
  action :install
end

Answer 3

The problem exists because https://supermarket.chef.io/cookbooks/mysql doesn't yet support for

cookbook 'mysql', '~> 8.0'

I added the following dependencies and it worked fine.

cookbook "yum-mysql-community", '~> 4.0.1'
cookbook 'mysql', '~> 6.0'
cookbook 'yum-centos', '~> 3.0.0'

Another thing to note here is to remember providing the package_name in the recipe. My recipe looks like this:

mysql_service 'foo' do
  port '3306'
  version '5.7'
  package_name 'mysql-server' 
  initial_root_password 'root'
  action [:create, :start]
end

Hope it helps!
