安装PHP7：
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
yum install -y php70w php70w-opcache
安装mysql
yum install mysql mysql-server mysql-devel -y
chkconfig mysqld on
service mysqld start
今天安装mysql 后面用navcat链接的时候报错
Navicat :1130-host . is not allowed to connect to this MySql server,MySQL
解决办法：
在mysql下输入命令：
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
即可，意思是myuser使用mypassword从任何主机连接到mysql服务器
