第一步:下載RPM包

wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm

第二步:安裝軟件源

rpm? -Uvh mysql57-community-release-el7-10.noarch.rpm

第三步:安裝服務(wù)端

yum install -y mysql-community-server

第四步:啟動(dòng)mysql

service mysqld start

systemctl start mysqld.service

第五步:查找默認(rèn)密碼

grep 'temporary password' /var/log/mysqld.log

第六步:登陸并修改密碼

修改密碼: ALTER USER 'root'@'localhost' IDENTIFIED BY '密碼';

密碼過于簡(jiǎn)單:

(1),修改validate_password_policy參數(shù)的值

set global validate_password_policy=0;

(2),再修改密碼的長(zhǎng)度

set global validate_password_length=1;

(3),修改密碼

ALTER USER 'root'@'localhost' IDENTIFIED BY '密碼';

第七步:授權(quán)其他機(jī)器登陸

GRANT ALL PRIVILEGES ON *.* TO 'root' @ '%' IDENTIFIED BY '數(shù)據(jù)庫密碼' WITH GRANT OPTION;

FLUSH PRIVILEGES;

第八步:數(shù)據(jù)庫重啟

service mysqld restart

systemctl restart mysqld.service
