背景介绍:
系统 rockey linux 9.4
mysql 8.4.0
我一开始想在系统上安装5.7的着,因为我有这个包,但是通过rpm安装的时候,到最后一步提示我没有/usbin/chkconfig 这个目录,怀疑是系统的问题,然后想安装chkconfig,最后也没弄上,没办法了,升级mysql吧,去官网下载最新版本了,最后安装成功。
1.下载mysql
下载地址:MySQL :: MySQL Community Downloads
2.安装
将下载好的mysql上传到服务,并解压
执行rpm安装命令:
按照下面的顺序执行,因为包会互相依赖
rpm -ivh mysql-community-common-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-libs-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-client-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-icu-data-files-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-server-8.4.0-1.el9.x86_64.rpm
执行启动命令:
systemctl start mysqld
systemctl status mysqld
3.修改密码,修改连接权限
grep 'temporary password' /var/log/mysqld.log
3.1执行登录命令:
mysql -uroot -p
输入日志中的密码
3.2执行修改密码的sql语句
//必须符合数据库的密码要求
alter user root@localhost identified by ‘Ldy_2024';
3.3修改root的链接权限
use mysql;
update user set host = '%' where user = 'root';
flush privileges;
4.利用navicat连接
