安装mysql前要先删除本机安装的mariadb
检查已经安装的mariadb列表
[root@iZ1i4qd6oynml0Z ~]# rpm -qa | grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64
然后执行删除
[root@iZ1i4qd6oynml0Z ~]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64
下面开始安装mysql
更新yum源
yum update
下载mysql yum包
wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
安装软件源
rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
安装mysql，后面的一直输入y就好了
yum install mysql-community-server
启动mysql
service mysqld start
查看MySQL运行状态
service mysqld status
查看mysql默认密码，最后那一串就是默认的密码
grep ‘temporary password‘ /var/log/mysqld.log
登录mysql，输入上面步骤得到的默认密码
[root@iZ1i4qd6oynml0Z ~]# mysql -u root -p
