缘
过了个周末,舒舒服服,把家里捣鼓了下,自己编了一个网格照片墙,把来做客的家具都安排好位置,本日,继承上班啦。
情况
开始之前,老生常谈,起首看看我服务器的信息:
- [root@VM-16-11-centos ~]# uname -a
- Linux VM-16-11-centos 3.10.0-1160.99.1.el7.x86_64 #1 SMP Wed Sep 13 14:19:20 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
复制代码 下载
虽然每次写MySQL教程都会写下载链接,这次依然附带上。提供两种方式下载,
** 下载地址:**直接下载mysql数据库tar格式,官网下载地址
** 下载页面:**在页面找自己想要的版本举行安装,官网下载页面
安装
- 离线服务器下载后放到服务器上,联网服务器直接使用下令下载:
- wget https://dev.mysql.com/get/mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar
复制代码- [root@VM-16-11-centos mysqls]# tar -xvf mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar

3. 安装解压出来的rpm安装包。如下:
- [root@VM-16-11-centos mysqls]# rpm -ivh *.rpm --nodeps --force
- warning: mysql-community-client-8.0.36-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID a8d3785c: NOKEY

4. 使用下令查看安装是否乐成,如下:
- [root@VM-16-11-centos mysqls]# systemctl status mysqld
- ● mysqld.service - MySQL Server
- Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
- Active: inactive (dead)
- Docs: man:mysqld(8)
- http://dev.mysql.com/doc/refman/en/using-systemd.html
- [root@VM-16-11-centos mysqls]#
复制代码 截图如下:

5. 启动mysql服务,如下:
- [root@VM-16-11-centos mysqls]# systemctl status mysqld
- ● mysqld.service - MySQL Server
- Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

- Mar 04 16:59:31 VM-16-11-centos systemd[1]: Started MySQL Server.
- [root@VM-16-11-centos mysqls]#
复制代码 截图如下:

6. 查看数据库密码,和往常一样依然是随机密码,有日志可知本次密码为k*;2bsNU)&Oo,如下:
- 2024-03-04T08:59:22.920568Z 0 [System] [MY-013169] [Server] /usr/sbin/mysqld (mysqld 8.0.36) initializing of server in progress as process 22031

复制代码 截图如下:

7.测试数据库链接,下令如下:
- [root@VM-16-11-centos ~]# mysql -u root -p
- Enter password:
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 8
- Server version: 8.0.36
- Copyright (c) 2000, 2024, Oracle and/or its affiliates.

- affiliates. Other names may be trademarks of their respective
- owners.
- Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
- mysql>
复制代码 截图如下:
可以毗连以后,记得修改密码,下令:
- ALTER USER USER() IDENTIFIED BY 'Root@123';
复制代码 截图如下:
如果有修改配置文件的需求,使用以下下令修改配置文件,修改后重启生效:
- [root@VM-16-11-centos ~]# vim /etc/my.cnf
复制代码 截图如下:
问题集锦
- 修改密码时报错:ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
解决方案:
意思是密码强度不敷,试试大小写数字加符号。
或者执行以下下令后重试:
- #查看密码配置
- show variables like 'validate_password%';
- #设置密码强度
- SET GLOBAL validate_password.policy=LOW;
- SET GLOBAL validate_password.length=0;
- SET GLOBAL validate_password.mixed_case_count=0;
- SET GLOBAL validate_password.number_count=0;
- SET GLOBAL validate_password.special_char_count=0;
- FLUSH PRIVILEGES;
- ALTER USER USER() IDENTIFIED BY 'iceter';
复制代码 修改乐成,注意:不要修改成关键字,比如:root,依然会报错。
- 安装时间报错:error: unpacking of archive failed: cpio: Bad magic
解决方案:
查看mysql版本与Linux体系版本是否一致。重新下载版本一致的举行安装即可。
