环境:
OS:kylin SP3
mysql:8.4.5 glibc2.17,建议安装glibc.2.28版本

查看系统glibc版本
[root@localhost ~]# ldd --version

[root@localhost ~]# getconf -a | grep glibc
GNU_LIBC_VERSION glibc 2.28

 

1.查看操作系统
[root@localhost ~]# uname -a
Linux localhost.localdomain 4.19.90-89.11.v2401.ky10.x86_64 #1 SMP Tue May 7 18:33:01 CST 2024 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# cat /etc/os-release
NAME="Kylin Linux Advanced Server"
VERSION="V10 (Halberd)"
ID="kylin"
VERSION_ID="V10"
PRETTY_NAME="Kylin Linux Advanced Server V10 (Halberd)"
ANSI_COLOR="0;31"

 

2.获取mysql安装介质
mysql-8.4.5-linux-glibc2.17-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-glibc2.17-x86_64.tar.xz
[root@localhost soft]# mv mysql-8.4.5-linux-glibc2.17-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
2025-09-17T09:21:30.029762Z 0 [System] [MY-015017] [Server] MySQL Server Initialization - start.
2025-09-17T09:21:30.030640Z 0 [System] [MY-013169] [Server] /home/middle/mysql8/bin/mysqld (mysqld 8.4.5) initializing of server in progress as process 30947
2025-09-17T09:21:30.046981Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2025-09-17T09:21:30.733139Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2025-09-17T09:21:32.492961Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: :dU&Wh;Qp8f6
2025-09-17T09:21:34.618698Z 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

Database changed
mysql> select host,user,plugin from user;
+-----------+------------------+-----------------------+
| host | user | plugin |
+-----------+------------------+-----------------------+
| % | hxl | caching_sha2_password |
| localhost | mysql.infoschema | caching_sha2_password |
| localhost | mysql.session | caching_sha2_password |
| localhost | mysql.sys | caching_sha2_password |
| localhost | root | caching_sha2_password |
+-----------+------------------+-----------------------+
5 rows in set (0.01 sec)

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';
