本篇文章详细讲解如何在银河麒麟 V10 （Kylin V10）系统中离线安装 MySQL 8.0 数据库。

本文适用于银河麒麟服务器操作系统V10 aarch64 版。

MySQL 安装包下载地址：

百度网盘：mysql_8.0_arm64.zip

下载以后，把压缩包上传到服务器并解压。

按顺序安装如下六个 rpm 包：

rpm -ivh mysql-community-common-8.0.46-1.el8.aarch64.rpm
rpm -ivh mysql-community-client-plugins-8.0.46-1.el8.aarch64.rpm
rpm -ivh mysql-community-libs-8.0.46-1.el8.aarch64.rpm
rpm -ivh mysql-community-client-8.0.46-1.el8.aarch64.rpm
rpm -ivh mysql-community-icu-data-files-8.0.46-1.el8.aarch64.rpm
rpm -ivh mysql-community-server-8.0.46-1.el8.aarch64.rpm

# 启动 MySQL
systemctl start mysqld

# 设置开机启动
systemctl enable mysqld

# 查看运行状态（可选）
systemctl status mysqld

在 /var/log/mysqld.log 日志文件中找到 mysql 临时密码，类似如下的一行日志：

1
A temporary password is generated for root@localhost: O*!srpLCo0We

使用如下命令：

1
cat /var/log/mysqld.log

从日志中寻找临时密码：

使用临时密码登录 MySQL:

1
mysql -uroot -p

输完以上命令，按回车以后，粘贴密码，再按回车，就登录 MySQL 了。

登录 MySQL 以后执行 SQL 修改 root 密码:

-- 首先改一个强密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'Abcd@1234';

-- 策略改为LOW：只校验密码长度，不再要求大小写、特殊字符（临时）
SET GLOBAL validate_password.policy = LOW;
-- 把最小密码长度从默认8改为4（临时）
SET GLOBAL validate_password.length = 6;

-- 再修改为实际正在使用的密码（此处为示例密码，请改为实际使用的密码）
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

停止 MySQL：

1
systemctl stop mysqld

打开 MySQL 配置文件：

1
vim /etc/my.cnf

在原有 my.cnf 的 [mysqld] 下面接着粘贴如下几行配置：

1
2
3
4
5
6
[mysqld]
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
default-authentication-plugin=mysql_native_password
default-time-zone='+8:00'

在 my.cnf 的最末尾追加如下几行配置（可选）：

1
2
3
[client]
default-character-set=utf8mb4

保存退出。启动 MySQL：

1
systemctl start mysqld

登录MySQL，使用以下几个SQL语句查看配置是否正确：

1

4
5
6
7
8
SHOW VARIABLES LIKE '%character%';

SHOW VARIABLES LIKE '%collation%';

SHOW VARIABLES LIKE 'default_authentication_plugin';

SELECT user,host,plugin FROM mysql.user WHERE user='root';

主要验证打印的配置项和下面列出的配置项是否一致。

到此，MySQL 8.0 的安装和配置就搞好了。
