搜索了一些相关资料，应该是perl-Data-Dumper模组没有安装，导致安装过程中，初始化数据库失败，所以启动MySQL服务时，找不到相关系统表。具体参考官方文档MySQL-server RPM does not install perl-Data-Dumper as a dependency
Description:
MySQL-server requires perl-Data-Dumper to function. However, perl-Data-Dumper is not listed by the MySQL-server RPM as a dependency. So if a linux server does not have perl-Data-Dumper installed, the install-mysql-db will fail. And because of missing the initial database, the mysql service could not be started.
How to repeat:
On a linux server, make sure there is no perl-Data-Dumper installed. Install MySQL-server using yum. There should be error message complaining database could not be created.
Suggested fix:
Add perl-Data-Dumper as a dependency of the RPM package
解决方法：
1：安装perl-Data-Dumper模组。
[root@azrlnx06 mysql]# yum install -y perl-Data-Dumper
2：初始化数据库
[root@azrlnx06 mysql]# sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
[root@azrlnx06 mysql]# service mysql start Starting MySQL. SUCCESS! [root@azrlnx06 mysql]# /usr//bin/mysqladmin -u root password 'Qwe!23' Warning: Using a password on the command line interface can be insecure.
当然也可以卸载MySQL，然后重新安装，就能看到安装过程输出的Detail信息输出了。
