CentOS7 64位下MySQL5.7安装与配置（YUM）

# 下载mysql源安装包
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
 
安装mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm
yum install mysql-community-server
 
systemctl start mysqld
开机启动
systemctl enable mysqld
systemctl daemon-reload
 
查看默认密码 
grep 'temporary password' /var/log/mysqld.log
mysql -uroot -p

修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
注意：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误
添加远程账号
GRANT ALL PRIVILEGES ON *.* TO 'maoxu'@'%' IDENTIFIED BY 'MaoXu100!' WITH GRANT OPTION;
