centos7安装mysql8_/usr/sbin/restorecon: lstat(/home/rzrk/mysql) fail

#下载安装包
到官网确定一下最新包
https://dev.mysql.com/downloads/mysql/
这里不是为了追求新的，只是因为mysql官网会删掉老的包，不找版本号，下面的全是404

如图最新版本是8.0.13

版本号自己替换

#卸载自带的libs

[root@yg2q-f01-02-tyss-02 mysql8]# rpm -qa | grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64
[root@yg2q-f01-02-tyss-02 mysql8]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

这里顺序无所谓，报错再跑一边

因为是rpm安装，所以安装路径是默认的，
但是通常系统盘都很小，所以要修改数据目录

cat /etc/my.cnf 内容如下
这里要注意的就是server-id，自己修改一下，主从不能一致

[mysqld]

#basedir= /data/data/mysql/
datadir= /data/data/mysql/data/
port = 3306
socket = /data/data/mysql.sock
