Centos安装mysql8-tar.gz的方式

下载安装包

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.19-el7-x86_64.tar

清理原有mysql

查找mysql列表

[lidengyin@ldy ~]$ sudo rpm -pa | grep mysql

使用一下命令删除mysql列表

sudo yum mysql-*

如果不存在列表则省略

如果存在则删除

rm -rf 目录

查看是否安装mariable并卸载

rpm -qa | grep mariadb

安装mysql依赖包

yum install libaio

sudo tar -vxf mysql-8.0.19-el7-x86_64.tar

sudo tar -zxvf mysql-8.0.19-el7-x86_64.tar.gz -C /usr/local/software/mysql/

[lidengyin@ldy mysql-8.0.19-el7-x86_64]$ sudo mkdir mysqldb

chmod -R 777 /usr/local/software/mysql/mysql-8.0.19-el7-x86_64
chmod -R 777 /usr/local/software/mysql/mysql-8.0.19-el7-x86_64/mysqldb

创建mysql安装初始化文件，加入一下配置保存

sudo /etc/my.cnf

[lidengyin@ldy support-files]$ sudo cp mysql.server /etc/init.d/mysqld
[lidengyin@ldy support-files]$ service mysqld restart
