使用Chef

Question

我尝试在超市使用Chef mysql cookbook在 CentOS7 上安装 MySQL社区服务器： https://supermarket.chef.io/cookbooks/mysql

我的食谱文件：

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

我执行了：

berks install
kitchen test -d never

并出现以下错误：

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

Chef::Exceptions::Package

     22:         action :install
     23:       end
     24:

    yum_package("mysql-community-server") do

      action [:install]

      cookbook_name "obiwan"
      version "5.7.11-1.el7"
      flush_cache {:before=>false, :after=>false}
    end

    x86_64-linux

看起来像这个问题：https://github.com/chef-cookbooks/mysql/issues/443

谢谢你的时间！

Answer 1

我怀疑你可能需要使用不同的食谱，因为下面的命令并没有在centos 7 repo中显示mysql-community-server。也许尝试mariadb食谱。

yum provides mysql*

但是如果你真的必须安装mysql-community-server，你可能需要修改你的配方看起来像这样

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   

请记住，启动mysql-community时可能会遇到systemctl init脚本的一些问题。

Answer 2

我设法通过以下更改来修复此设置：

<强> metadata.rb

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

<强> 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

存在问题是因为https://supermarket.chef.io/cookbooks/mysql尚不支持

cookbook 'mysql', '~> 8.0'

我添加了以下依赖项，并且运行良好。

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

这里要注意的另一件事是记住在食谱中提供 package_name 。我的食谱如下：

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

希望有帮助！
