tar -xvf mysql-8.0.16-2.el7.x86_64.rpm-bundle.tar
mysql-8.0.16-2.el7.x86_64.rpm-bundle.tar解压后有如下8个文件:

建议装之前先把之前的mysql相关包全部卸载,rpm -e --nodeps <包名>即可
按如下顺序依次安装:

显示如下信息说明安装成功

ll /etc/my.cnf
-rw-r--r-- 1 root root 1243 May 3 05:11 /etc/my.cnf
vim /etc/my.cnf
添加如下信息:
#配置MYSQL大小写敏感(1-不敏感,0-敏感) lower_case_table_names=1
注意!MySQL8.0想要 大小写不敏感,必须在安装好MySQL后未启动之前 修改MySQL配置文件设置为不敏感,一旦启动后,再设置是无效的,而且启动会报错。
如果已经晚了,那必须把MySQL数据库文件全部 删除,修改配置文件再启动。
如果数据不重要,可以先关闭服务删掉数据,再执行以上操作:
service mysqld stop rm -rf /var/lib/mysql
mysqld --initialize --console
chown -R mysql:mysql /var/lib/mysql/
systemctl start mysqld
备注:
停止命令:service mysqld stop
service mysqld status
