1. MySQL 8.0.29版本下载

直接官网下载：

https://dev.mysql.com/downloads/mysql/

选择版本：

2. 安装MySQL

2.1 删除原有的mariadb

先查看一下是否已经安装了

rpm -qa | grep mysql
rpm -qa | grep mariadbrpm -e --nodeps mariadb-libs
rpm -e mariadb-server --nodeps
yum -y remove mysql*
yum -y remove mariadb*

删除mariadb，命令：

rpm -e --nodeps mariadb-libsrpm -e mariadb-server --nodeps

2.2 解压缩mysql离线安装包

[root@localhost MYSQL安装包]# tar xvf mysql-8.1.0-1.el8.aarch64.rpm-bundle.tar

逐个安装，命令如下：

必须安装

[root@localhost MYSQL安装包]# rpm -ivh mysql-community-common-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-client-plugins-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-libs-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-client-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-icu-data-files-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-server-8.1.0-1.el8.aarch64.rpm[root@localhost MYSQL安装包]# rpm -ivh mysql-community-devel-8.1.0-1.el8.aarch64.rpm

查看mysql

[root@localhost MYSQL安装包]# rpm -qa |grep mysqlmysql-community-client-8.1.0-1.el8.aarch64
mysql-community-server-8.1.0-1.el8.aarch64
mysql-community-client-plugins-8.1.0-1.el8.aarch64
mysql-community-icu-data-files-8.1.0-1.el8.aarch64
mysql-community-common-8.1.0-1.el8.aarch64
mysql-community-devel-8.1.0-1.el8.aarch64
mysql-community-libs-8.1.0-1.el8.aarch64

3. 初始化mysql服务

3.1 查看服务状态

命令：

[root@localhost MYSQL安装包]# systemctl status mysqld● mysqld.service - MySQL ServerLoaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor pres>Active: inactive (dead)Docs: man:mysqld(8)http://dev.mysql.com/doc/refman/en/using-systemd.html

接下来要启动MySQL，通过执行以下命令启动：

[root@localhost MYSQL安装包]# systemctl start mysqld

启动过程并不会返回任何信息即为成功。

再次查询状态

[root@localhost MYSQL安装包]# systemctl status mysqld● mysqld.service - MySQL ServerLoaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor pres>Active: active (running) since Mon 2023-07-31 14:52:26 CST; 11s agoDocs: man:mysqld(8)http://dev.mysql.com/doc/refman/en/using-systemd.htmlProcess: 9165 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0>Main PID: 9242 (mysqld)Status: "Server is operational"Tasks: 38Memory: 596.7MCGroup: /system.slice/mysqld.service└─9242 /usr/sbin/mysqld

激活状态Active显示为active，则表示启动成功。

3.2 配置MySQL

MySQL安装完成后需要对MySQL做基础配置，包括首次登录修改用户密码、数据文件位置调整、redo log大小与数量调整、undo 表空间调整、ibdata表空间调整、binlog+errorlog+slowlog+pid+socket等文件调整、性能参数调整，这些调整都可以通过修改my.cnf参数文件实现。

在MySQL安装完成第一次启动MySQL服务后，会自动为MySQL的root用户生成一个随机初始化密码，并在MySQL的errorlog文件中记录下来，我们要找到它并用它登录MySQL，修改root用户密码后才能执行任何其它操作：

• 找到初始化密码

[root@localhost MYSQL安装包]# grep password /var/log/mysqld.log2023-07-31T06:52:18.907755Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: #SL7tAyY5ih)

#SL7tAyY5ih)即为初始化密码，注意是冒号后面的所有字符都是密码

• 使用上面的初始化密码登录MySQL

[root@localhost MYSQL安装包]# mysql -uroot -p

• 修改root密码

使用初始化密码登录MySQL后只能执行修改密码的操作，其他任何操作都是不可能的，使用以下命令修改密码：

mysql> alter user user() identified by 'LaoGeDB123!';Query OK, 0 rows affected (0.02 sec)

密码修改成功后，执行以下命令查看MySQL基本信息：
