我在 Centos 7 上通过命令安装 mysql
yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
在那之后：
yum install mysql-community-server
这是进程运行后的错误：

请帮我解决这个问题，我搜索了很多页面但仍然没有找到解决方案
已解决：我尝试yum remove Percona*;
重新安装 mysql，成功了。但不确定接下来会不会有什么问题。谢谢大家。
答案1
这可能是因为您的系统上安装了 percona 服务器。
yum list installed | grep -i percona
您可以将 repoquery 与“--file”标志一起使用，以便查看该文件属于哪个包：
repoquery --file /usr/bin/mysql
尝试卸载 percona 服务器，然后尝试重新安装 mysql。
