我尝试了以下步骤来解决该问题，

1. 重新安装mysql最新版本8.0.36。

2. 还尝试执行以下步骤：mysql2 0x0000000000000000 处的分段错误

   sudo apt remove libmariadbd-dev
   sudo apt install libmariadbd-dev
   gem install mysql2 -v '0.5.6' 
   

但是没有任何作用，仍然是同样的问题。如有任何帮助，我们将不胜感激。

Answer 1

如果有人遇到同样的问题，可以尝试以下步骤。希望它对某人有用

从此文档安装 openssl https://deanpcmad.com/2022/installing-older-ruby-versions-on-ubuntu-22-04/

2）如果您使用的是rvm，您可以在从上面的文档安装openssl-1.1.1g后执行以下命令来安装ruby以获得此ssl版本支持

 rvm install "ruby-2.5.3" --with-openssl-dir=$HOME/.openssl/openssl-1.1.1g
