這篇文章主要為大家詳細介紹了linux下使用RPMlinuxlinux5.7.17的相關代碼，具有一定的參考價值，感興趣的小伙伴們可以參考一下
linux下MySQL5.7 rpm安裝方式記錄，供大家參考，具體內容如下
linux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 -p mysql> set password='Pwd@123456'; mysql> grant all privileges on *.* to 'root'@'%' identified by 'Pwd@123456';
密碼復雜度linux：
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，linux。）
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）
