在centos7下安裝mysql

1.一般centos7預設安裝了mariadb,這裡把它解除安裝。

rpm -qa|grep mariadb

rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

rpm -ivh mysql-community-common-5.7.24-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.24-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.30-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.24-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.24-1.el7.x86_64.rpm

臨時：

setenforce 0

/etc/selinux/config

selinux=disabled

/etc/my.cnf

5.啟動mysql服務

systemctl start mysqld

grep password /

var/log/mysqld.log

mysql -uroot –p

set global validate_password_policy=0;

set password = password(

"yfbzx,./"
);

grant all privileges on *

.* to 'test'@'%' identified by '123456'
;

flush privileges;
