mariadb-libs is obsoleted by mysql-community-libs-compat-5.7.33-1.el7.x86_64
perl(JSON) is needed by mysql-community-test-5.7.33-1.el7.x86_64
因为mysql的server端须要perl语言的支持，所以咱们还须要在系统中安装perl支持：
安装依赖perl

安装完mysql后，修改data目录
方式一：
mysqld --default-file=/etc/my.cnf --datadir=/data01/mysql --user=mysql --initialize
在初始化的时候，就将路径指定到数据盘上，而不是默认的/var/lib/mysql下。
方式二：
my.cnf默认文件位置
# ll /etc/my.cnf
-rw-r--r-- 1 root root 960 Dec 10 2020 /etc/my.cnf
data默认文件位置
# ll /var/lib/mysql
total 122952
