我这里是RHEL6.5的系统，因此选择RedHat 6 x86,64bit操作系统---下载第一个RPM Bundle即可--MySQL-8.0.11-1.el6.x86_64.rpm-bundle.tar。
目前MySQL8.0.11社区版提供了多种多样的安装方式，但是并未发现针对Linux Generic安装包包含的mysql_secure_installation的安装说明。
MySQL官网地址：https://dev.mysql.com/downloads/mysql/
因此这里使用推荐的RPM安装：
一、mysql-8.0.11-1.el6.x86_64.rpm-bundle.tar解压后有如下7个文件：
-rw-r--r-- 1 root root 28987588 Apr 9 01:06 mysql-community-client-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 672184 Apr 9 01:06 mysql-community-common-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 4443296 Apr 9 01:06 mysql-community-devel-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 2579460 Apr 9 01:06 mysql-community-libs-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 1902676 Apr 9 01:06 mysql-community-libs-compat-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 395918848 Apr 9 01:07 mysql-community-server-8.0.11-1.el6.x86_64.rpm
-rw-r--r-- 1 root root 49092596 Apr 9 01:07 mysql-community-test-8.0.11-1.el6.x86_64.rpm
然后创建mysql用户：
useradd mysql
passwd mysql
二、安装顺序为：（建议装之前先把之前的mysql相关包全部卸载，rpm -e --nodeps <包名>即可）
