[root@localhost soft]# getconf -a | grep glibc
GNU_LIBC_VERSION glibc 2.38

1.查看操作系统
[root@localhost soft]# uname -a
Linux localhost.localdomain 6.6.0-32.7.v2505.ky11.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Jul 4 13:31:43 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost soft]# cat /etc/os-release
NAME="Kylin Linux Advanced Server"
VERSION="V11 (Swan25)"
ID="kylin"
VERSION_ID="V11"
PRETTY_NAME="Kylin Linux Advanced Server V11 (Swan25)"
ANSI_COLOR="0;31"

2.获取mysql安装介质
mysql-8.4.5-linux-glibc2.28-x86_64.tar.xz

3.创建mysql用户和用户组(系统已经创建不需要创建)
[root@localhost soft]#groupadd mysql
[root@localhost soft]#useradd -g mysql mysql
[root@localhost soft]#passwd mysql

4.创建安装主目录
[root@localhost soft]#mkdir -p /home/middle/

5.下载解压安装
[root@localhost soft]# tar -xvf mysql-8.4.5-linux-glibc2.28-x86_64.tar.xz
[root@localhost soft]# mv mysql-8.4.5-linux-glibc2.28-x86_64 /home/middle/mysql8

6.创建相应的目录
[root@node1 mysql8]# cd /home/middle/mysql8
[root@localhost mysql8]# mkdir data ##数据文件目录
[root@localhost mysql8]# mkdir conf ## 配置文件目录
[root@localhost mysql8]# mkdir -p mysqllog/relaylog ##主从环境relaylog
[root@localhost mysql8]# mkdir -p mysqllog/logfile ##错误日志文件
[root@localhost mysql8]# mkdir -p mysqllog/binlog ##binlog文件
[root@localhost mysql8]# mkdir -p secure_file ##secure_file_priv参数指定路

7.初始化数据库
root账户下
[root@localhost bin]# cd /home/middle/mysql8/bin
[root@localhost bin]# ./mysqld --initialize --lower-case-table-names=1 --user=mysql --basedir=/home/middle/mysql8 --datadir=/home/middle/mysql8/data
2025-09-18T02:27:01.984381Z 0 [System] [MY-015017] [Server] MySQL Server Initialization - start.
2025-09-18T02:27:01.985878Z 0 [System] [MY-013169] [Server] /home/middle/mysql8/bin/mysqld (mysqld 8.4.5) initializing of server in progress as process 8838

2025-09-18T02:27:02.384836Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2025-09-18T02:27:04.442315Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: GzVozCwHA7;W
2025-09-18T02:27:07.346873Z 0 [System] [MY-015018] [Server] MySQL Server Initialization - end.

8.准备配置文件

9.生成错误日志文件
[root@localhost conf]# echo>/home/middle/mysql8/mysqllog/logfile/mysql-err.log

10.修改目录权限
[root@localhost mha]# cd /home/middle
[root@localhost opt]# chown -R mysql:mysql ./mysql8

11.启动
(在root用户下执行)
[root@node1 opt]# /home/middle/mysql8/bin/mysqld_safe --defaults-file=/home/middle/mysql8/conf/my.cnf --user=mysql &

12.登陆数据库修改相应用户密码
[root@localhost middle]# /home/middle/mysql8/bin/mysql -h localhost -uroot -P13306 -p

mysql> select version();
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

提示修改密码
alter user 'root'@'localhost' identified by 'mysql';
flush privileges;

14.创建数据库
mysql> create database db_test;
Query OK, 1 row affected (0.02 sec)

15.创建开发用户
create user 'hxl'@'%' identified by 'mysql';
grant all privileges on db_test.* to 'hxl'@'%' with grant option;

创建完成后查看加密方式:
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

mysql>

修改密码认证方式,确保旧版本的navicate能够登录
alter user 'hxl'@'%' identified with mysql_native_password by 'mysql';
