进入Mysql官网获取RPM包的下载地址:https://dev.mysql.com/downloads/repo/yum/
2.1.先安装wget,避免下载时未找到命令
yum -y install wget
2.2.下载mysql源安装包
[root@localhost ~]# wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
2.3.安装mysql源
yum -y localinstall mysql57-community-release-el7-11.noarch.rpm
2.4.在线安装mysql
yum -y install mysql-community-server
2.5.启动mysql服务并设置开机启动
systemctl start mysqld
systemctl enable mysqld
systemctl daemon-reload
方法1: 用SET PASSWORD命令
mysql -u root
mysql> SET PASSWORD FOR ‘root‘@‘localhost‘ = PASSWORD(‘newpass‘);
方法2:用mysqladmin
mysqladmin -u root password "newpass"
如果root已经设置过密码,采用如下方法
mysqladmin -u root password oldpass "newpass"
方法3: 用UPDATE直接编辑user表
mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD(‘newpass‘) WHERE user = ‘root‘;
mysql> FLUSH PRIVILEGES;
在丢失root密码的时候,可以这样
mysqld_safe --skip-grant-tables&
mysql -u root mysql
mysql> UPDATE user SET password=PASSWORD("new password") WHERE user=‘root‘;
mysql> FLUSH PRIVILEGES;
[mysqld]
character_set_server=utf8
init_connect=‘SET NAMES utf8‘
[root@localhost ~]# vi /etc/my.cnf
