安装部署mysql8.0

  1. #1、解压
  2. [root@mysql-36 src]# tar xf mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar
  3. [root@mysql-36 src]# ls
  4. mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar                mysql-community-devel-8.0.28-1.el7.x86_64.rpm            mysql-community-libs-compat-8.0.28-1.el7.x86_64.rpm

  9. #2、安装前环境监测
  10. 在MySQL被收购后，MySQL最初的作者担心MySQL存在闭源的风险，在MySQL的分支上开发了mariadb。后来一些Linux分发版就将mariadb作为系统默认安装的数据库系统，理论上mariadb兼容MySQL，甚至某些方面性能更好。（当然，我没有测试过）
  11. root@mysql-36 src]# rpm -qa|grep mariadb
  12. mariadb-libs-5.5.56-2.el7.x86_64
  13. [root@mysql-36 src]# yum remove mariadb* -y
