centos7安装mysql

1.yum install mysql

yum install mysql-server(这个可能报错，执行yum install mariadb-server mariadb，启动systemctl start mariadb，再登录mysql---mysql -u root -p )

yum install mysql-devel

2.修改数据库密码

grant all privileges on *.* to 'root' @'%' identified by 'root';  ---密码改为root

flush privileges;

3.开放3306端口

firewall-cmd --zone=public --add-port=3306/tcp --permanent

firewall-cmd --reload----重启防火墙

到此mysql安装设置完成。

 

PS---执行wget命令报错，可以执行yum -y install wget
