linux下MySQL5.7 rpm安裝方式記錄，供大家參考，具體內容如下
刪除舊包：
# rpm -qa | grep -i mysql# rpm -ev mysql-libs-* --nodeps
安裝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
啟動、停止：
# service mysqld start# service mysqld stop# service mysqld status
初始隨機密碼：
# cat /var/log/mysqld.log | more
修改初始密碼及授權遠程訪問：
# mysql -uroot -pmysql> set password='Pwd@123456';mysql> grant all privileges on *.* to 'root'@'%' identified by 'Pwd@123456';
密碼復雜度屬性：
mysql> set global validate_password_policy=0;
validate_password_policy有以下取值：（默認是1，即MEDIUM，所以剛開始設置的密碼必須符合長度，且必須含有數字，小寫或大寫字母，特殊字符。）
修改數據目錄：
新目錄需要給mysql用戶授權，mysqld_safe日志文件授權，關閉selinux（沒找到相關策略設置的方法）

其他命令：
# mysqladmin -u root -p passwordmysql> select version();# chkconfig --list# chkconfig --level 345 mysqld on# netstat -na | grep 3306
