| 导读 | MySQL是一种关系数据库管理系统（RDBMS），作为服务器运行，提供对多个数据库的多用户访问。 这是指导，如何在Fedora 28/27/26，CentOS 7.5 / 6.10和Red Hat（RHEL）7.5 / 6.10上安装或升级MySQL社区服务器最新版本8.0（8.0.12）/5.7(5.7.23）。 本指南当然也适用于Oracle Linux和Scientific Linux。 |
注意：如果要升级MySQL（从早期版本），请确保备份（转储和复制）数据库和配置。 记得运行mysql_upgrade命令。
安装 MySQL YUM 仓库源
## Fedora 28 ## dnf install https://dev.mysql.com/get/mysql80-community-release-fc28-1.noarch.rpm ## Fedora 27 ## dnf install https://dev.mysql.com/get/mysql80-community-release-fc27-1.noarch.rpm ## Fedora 26 ## dnf install https://dev.mysql.com/get/mysql80-community-release-fc26-1.noarch.rpm CentOS 和 Red Hat (RHEL) ## CentOS 7 and Red Hat (RHEL) 7 ## yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm CentOS 6 and Red Hat (RHEL) 6 ## yum localinstall https://dev.mysql.com/get/mysql80-community-release-el6-1.noarch.rpm
安装和更新
1.安装
Fedora 28/27/26 dnf install mysql-community-server CentOS 7.5/6.10 and Red Hat (RHEL) 7.5/6.10 yum install mysql-community-server
2.安装 MySQL 5.7.23
Fedora 28/27/26 dnf --disablerepo=mysql80-community --enablerepo=mysql57-community install mysql-community-server CentOS 7.5/6.10 and Red Hat (RHEL) 7.5/6.10 yum --disablerepo=mysql80-community --enablerepo=mysql57-community install mysql-community-server
3. 开启 MySQL server 并设置开机自启
Fedora 28/27/26 CentOS 7.5 Red Hat (RHEL) 7.5 systemctl start mysqld.service use restart after update systemctl enable mysqld.service CentOS 6.10 and Red Hat (RHEL) 6.10 /etc/init.d/mysql start use restart after update
OR ##
service mysql start ## use restart after update chkconfig --levels 235 mysqld on
4. 获取初始的随机密码
grep 'A temporary password is generated for root@localhost' /var/log/mysqld.log |tail -1
Example Output:
2018-11-20T21:11:44.229891Z 1 [Note] A temporary password is generated for root@localhost: -et)QoL4MLid
And root password is: -et)QoL4MLid
5.重置密码
alter user root@localhost identified by '自定义密码'; 新密码必须大小学数字特殊符号全部具备。
6. 连接本地mysql服务器
mysql -u root -p OR ## mysql -h localhost -u root -p
