基本上开源的软件都支持三种安装方式，即rmp方式安装，源码安装和二进制方式安装。在实际生成环境中用到最多的方式莫过于二进制方式安装或者rmp方式安装。其中rmp方式安装是最常见的，比如Linux的Redhat/CentOS法相版本的yum管理工具，其实就是基于rpm方式安装，只不过它能帮我们解决rpm包的依赖关系即可。我在之前的笔记中介绍过MySQL5.7版本的以上三种安装方式。最近在学习MySQL8.0的一些心特性，顺手整理一下学习笔记，本片博客我们一起来学习一下MySQL8.0版本的yum安装方式。
我个人并不喜欢yum方式安装，虽然它的安装方式比较简单 ，官方说需要配置yum源即可。但是yum方式安装的可移植性相当差，官方参考地址：https://dev.mysql.com/doc/refman/8.0/en/linux-installation-yum-repo.html。
一.安装MySQL前准备工作
1>.操作环境
[root@node101 ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@node101 ~]# [root@node101 ~]# uname -r 3.10.0-327.el7.x86_64 [root@node101 ~]# [root@node101 ~]# uname -m x86_64 [root@node101 ~]# [root@node101 ~]# hostname node101.yinzhengjie.org.cn [root@node101 ~]# [root@node101 ~]# hostname -i 172.30.1.101 [root@node101 ~]# [root@node101 ~]# free -h total used free shared buff/cache available Mem: 3.5G 124M 3.1G 8.4M 232M 3.2G Swap: 2.0G 0B 2.0G [root@node101 ~]# [root@node101 ~]#
2>.卸载与mysql相关的服务
[root@node101 ~]# ls /etc/my.cnf #我们查看mysql的默认配置文件存放路径，发现我们还没有安装就已经又它存在啦！ /etc/my.cnf [root@node101 ~]# [root@node101 ~]# rpm -qa | grep mysql #果不其然， 我们发现的确安装了mysql相关的安装包 pcp-pmda-mysql-3.10.6-2.el7.x86_64 [root@node101 ~]# [root@node101 ~]# rpm -qa | grep mariadb #原来我们在安装CentOs操作系统时，我的虚拟化软件默认的安装方式就帮我安装了mariadb呀！ mariadb-libs-5.5.44-2.el7.centos.x86_64 [root@node101 ~]#
