二、基于官方源代码RMP构建自定义MySQLRPM（一般用于企业内部开发，生产中还是MySQL包的方式安装）
创建一个普通用户，用于构建自定义的RPM包
# useradd tubeliu
# cp mysql-community-5.7.22-1.el7.src.rpm /home/tubeliu/
# chown tubeliu.tubeliu /home/tubeliu/ -R
# yum list | grep rpm-build
# yum -y install rpm-build
# su - tubeliu
ls
mysql-community-5.7.22-1.el7.src.rpm
$ rpmbuild ~
错误：文件 /home/tubeliu 不是常规文件。
$ ls
mysql-community-5.7.22-1.el7.src.rpm rpmbuild
