1.官网下载安装包
找到自己要的版本，centos用red hat的
2.通过vmware共享文件夹或者远程软件传包到/root下
3.清除centos7自带的mariaDB
找到有关Mariaadb的软件
rpm -qa | grep -i mariadb
卸载检测出来的软件，检测出多少卸载多少
rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
查找是否有相关配置目录及文件，如有，则 rm -rf 删除
find / -iname mariadb
4.将安装包解压
tar -xvf MySQL-5.6.47-1.el7.x86_64.rpm-bundle.tar
按顺序安装下面三个rpm
rpm -ivh /root/MySQL-server-5.6.47-1.el7.x86_64.rpm
rpm -ivh /root/MySQL-devel-5.6.47-1.el7.x86_64.rpm
rpm -ivh /root/MySQL-client-5.6.47-1.el7.x86_64.rpm
启动mysql
service mysql start
5.mysql初始化配置
之前安装第一个rpm的时候有提示语
You will find that password in ‘/root/.mysql_secret’.
按照提示找到初始密码并复制下来
cat /root/.mysql_secret
按照之前提升初始化mysql
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
/usr/bin/mysql_secure_installation
会让及输入之前查看的初始密码
之后问你怎么设置只管y就够了
第一个y是设置新密码
