这个错误可能是因为MySQL未能创建默认的数据目录/var/lib/mysql。您可以尝试手动创建该目录并授予MySQL用户适当的权限,然后再次尝试安装MySQL。
以下是可以尝试的步骤:
1. 在终端中执行以下命令以创建/var/lib/mysql目录:
sudo mkdir /var/lib/mysql
2. 授予MySQL用户适当的权限:
sudo chown -R mysql:mysql /var/lib/mysql
sudo chmod -R 755 /var/lib/mysql
3. 重新运行MySQL安装程序。
如果您仍然遇到问题,请检查MySQL安装程序的日志文件以获取更多信息,或者尝试使用备用的MySQL安装程序。
