首先,换yum源下载对应版本的repo文件wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo清除旧的yum缓存并生成新的yum缓存代码语言：javascript复制# yum clean all
# yum makecache更新代码语言：javascript复制# yum update -y下面根据需求,安装对应版本的MySQL安装mysql5.6wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install mysql-server -y
service mysqld start
service mysqld status
systemctl enable mysqld.service
grep “password” /var/log/mysqld.log找初始密码，如果报找不到文件那就试试grep “password” /var/log/mysql/mysqld.log
mysqladmin -uroot -p password NewPassword回车输入初始密码来重置密码
安装mysql5.7wget http://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpm
rpm -ivh mysql57-community-release-el7-11.noarch.rpm
yum install mysql-server -y
service mysqld start
service mysqld status
systemctl enable mysqld.service
grep “password” /var/log/mysqld.log找初始密码，如果报找不到文件那就试试grep “password” /var/log/mysql/mysqld.log
mysqladmin -uroot -p password NewPassword回车输入初始密码来重置密码
安装mysql8.0wget http://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm
rpm -ivh mysql80-community-release-el7-3.noarch.rpm
yum install mysql-server -y
service mysqld start
service mysqld status
systemctl enable mysqld.service
配置8.0版本
修改密码,默认也是没有密码的直接回车输入新密码
代码语言：javascript复制 [root@localhost ~]# mysqladmin -uroot -p password
Enter password:
New password:
Confirm new password:
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.方法一:
Mysql默认不允许远程登录，所以需要开启远程访问权限
可以先查看user表
select user,authentication_string,host from user;
默认都是localhost
update user set host = ‘%’ where user = ‘root’;
代码语言：javascript复制flush privileges;
如果没有开放连接权限，使用navicat等客户端连接数据库时会报如下错误：
3、还原密码验证插件，将MySQL8的密码认证插件由caching_sha2_password更换成mysql_native_password：
代码语言：javascript复制ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'passowrd';如果没有更换插件，连接时会报如下错误：
注意事项:
如果报以下错误,可根据提示删除掉对应的冲突包
代码语言：javascript复制[root@localhost ~]# rpm -ivh mysql57-community-release-el7-11.noarch.rpm
警告：mysql57-community-release-el7-11.noarch.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY
错误：依赖检测失败：
mysql-community-release 与 mysql57-community-release-el7-11.noarch 冲突代码语言：javascript复制 命令如下格式:
rpm -e --nodeps 后面加上冲突的文件名,如下:
rpm -e --nodeps mysql-community-release之后在执行安装程序即可完整安装
另外,针对学习阶段,
MySQL5.7不能修改简单密码的问题,我这里做了总结,请参考:
MySQL5.7修改密码问题解决方案
最后献上我今天安装MySQL的过程指令:
代码语言：javascript复制Activate the web console with: systemctl enable --now cockpit.socket
