其中 Could not generate RSA private key required for X509 certificate. 这一条报错不知道怎么解决，求各位大佬指点

mysql5.7.30是从官网下的rpm包安装，其中的mysql-community-test-5.7.30-1.el6.x86_64.rpm包未安装


-----------------------------------------------
手动执行数据库初始化后
mysqld --initialize --user=mysql

又提示一下报错

他是要访问哪个目录没有权限？ 我是用root用户执行的启动为啥会没有权限呢？怎么解决？

问题解决了，因为新装的系统没有禁用selinux导致，把selinux禁用后重启就好了。
