本文提供了MySQL 8.0.15的下载链接，并详细介绍了如何在Linux上配置和部署MySQL，包括解压、创建系统账号、配置my.cnf、设置环境变量、解决libaio.so.1错误、初始化数据库、修改默认密码等步骤。

由于直接在网上下载mysql的文件太慢了，本人就直接把自己下载好的东西，分享给大家。提供给大家下载。

接下来，本人将介绍该怎么配置和部署mysql
因为首先下载下来的文件是xz格式，所以需要用此命令将文件改为tar格式

xz -d  mysql-8.0.15-linux-glibc2.12-x86_64.xz

接下来，就可以正常解压tar文件，正常情况下，需要将mysql解压并移动到/usr/local/mysql文件夹

tar xf mysql-8.0.15-linux-glibc2.12-x86_64.tar /usr/local/mysql

在这里插入图片描述
接下来需要建立一个mysql系统账号

adduser mysql      //mysqls是账号名字，可自行取

之后需要在 /etc/my.cnf中进行配置

之后需要建立各种文件夹存储文件

最后需要在/etc/profile文件末尾添加配置mysql变量方便启动

接着初始化

mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

在运行此命令时，本人遇到了这个问题
mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
读者可以执行这种命令

yum install -y libaio

就可以解决了
最后把/mysql/support-files/mysql.sever文件移动到/etc/init.d/mysqld

cp  mysql.server /etc/init.d/mysqld

初始化

/etc/init.d/mysqld start

运用ps命令查看mysql进程状态

ps -ef | grep mysql

在这里插入图片描述
之后进行密码修改

cd sql_log
grep password mysql-error.log

在这里插入图片描述

之后修改密码

alter user user() identified by '123456'

在这里插入图片描述
之后再次mysql -uroot -p输入123456就可以进入了
