删除用不到的rpm包
rm -rf ~/soft/mysql/mysql-community-debuginfo-8.0.31-1.el7.x86_64.rpm rm -rf ~/soft/mysql/mysql-community-devel-8.0.31-1.el7.x86_64.rpm rm -rf ~/soft/mysql/mysql-community-embedded-compat-8.0.31-1.el7.x86_64.rpm rm -rf ~/soft/mysql/mysql-community-server-debug-8.0.31-1.el7.x86_64.rpm rm -rf ~/soft/mysql/mysql-community-test-8.0.31-1.el7.x86_64.rpm
删除下载的rpm-bundle tar包
[hadoop@node3 installfile]$ rm -rf mysql-8.0.31-1.el7.x86_64.rpm-bundle.tar
安装
切换到解压目录，并创建安装脚本install_mysql.sh
[hadoop@node3 installfile]$ cd ~/soft/mysql/ [hadoop@node3 mysql]$ vim install_mysql.sh
脚本内容如下：
#!/bin/bash
set -x
[ "$(ls *.rpm | wc -l)" = "7" ] || exit 1
