lamp 独立mysql_lamp or lnmp 环境搭建之独立安装mysql数据库

lamp or lnmp 环境搭建,如果mysql 是独立安装的则需要授权：

单独一台服务器独立安装mysql

安装后，优化服务器。

授权

实例如下：

创建用户

CREATE USER demo IDENTIFIED BY “passwd123”;

授权使用mysql数据库下面的所有表

GRANT ALL PRIVILEGES ON mysql.* TO 'demo'@'%'IDENTIFIED BY 'passwd123'WITH GRANT OPTION;

FLUSH PRIVILEGES;

-------------------------------------------------------------------------------------------

实例二

授权所有的数据库给myuser连接

CREATE USER myuser IDENTIFIED BY “mypassword”;

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH PRIVILEGES;

实例三

授权所有的数据库给myuser从192.168.1.3上连接

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'10.89.1.30'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH PRIVILEGES;

4.web服务器连接测试

[root@weblnmp blog]# vi oldboy_mysql.php

$link_id=mysql_connect('10.89.1.30','myuser','mypassword') or mysql_error();

if ($link_id) {

echo "mysql _OK()";

}

else {

echo "mysql _error()";

}
