CentOS 8 安装MySQL(各版本完美解决方案)
2024-05-20 02:05:17
CentOS 8 安装MySQL
- 首先,换yum源
- `wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo`
- 下面根据需求,安装对应版本的MySQL
- 安装mysql5.6
- 安装mysql5.7
- 安装mysql8.0
- 注意事项:
- MySQL5.7不能修改简单密码的问题
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
# yum clean all
# yum makecache
- 更新
# yum update -y
下面根据需求,安装对应版本的MySQL
安装mysql5.6
wget 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mysql5.7
wget 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mysql8.0
wget 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
[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’;
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：
在这里插入图片描述
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：
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
[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
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:
