linux下MySQL5.7 rpm安装方式记录，供大家参考，具体内容如下
删除旧包：
# rpm -qa | grep -i mysql # rpm -ev mysql-libs-* --nodeps
安装rpm包：
# rpm -ivh mysql-community-common-5.7.17-1.el7.x86_64.rpm # rpm -ivh mysql-community-libs-5.7.17-1.el7.x86_64.rpm # rpm -ivh mysql-community-client-5.7.17-1.el7.x86_64.rpm # rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm
启动、停止：
# service mysqld start # service mysqld stop # service mysqld status
初始随机密码：
# cat /var/log/mysqld.log | more
修改初始密码及授权远程访问：
# mysql -uroot -p mysql> set password='Pwd@123456'; mysql> grant all privileges on *.* to 'root'@'%' identified by 'Pwd@123456';
密码复杂度属性：
mysql> set global validate_password_policy=0;
validate_password_policy有以下取值：（默认是1，即MEDIUM，所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。）
修改数据目录：
新目录需要给mysql用户授权，mysqld_safe日志文件授权，关闭selinux（没找到相关策略设置的方法）

SELINUXTYPE=targeted */ # service mysqld start
其他命令：
# mysqladmin -u root -p password mysql> select version(); # chkconfig --list # chkconfig --level 345 mysqld on # netstat -na | grep 3306
