Mysql安裝rpm文件

最近安裝tar文件（https://blog.csdn.net/zhaofengdeng/article/details/80367535），安裝失敗

所以選擇安裝rpm文件

下載地址

https://dev.mysql.com/downloads/mysql/

下載 comon ,libs,client,server

運行命令，有安裝順序

rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

相關命令

# 啓動mysql
service mysqld start

# 停止mysql
service mysqld stop

# 重啓mysql
service mysqld restart

查看臨時密碼

grep password /var/log/mysqld.log

修改密碼：

設置密碼策略爲低，要不可能修改的密碼簡單修改失敗

set global validate_password_policy=LOW; 
alter user 'root'@'localhost' identified by '密碼';

設置允許遠程連接數據庫，命令如下：

use mysql;
update user set user.Host='%' where user.User='root'; 

刷新權限，命令如下：

flush privileges;
