错误:致命错误:未捕获的异常 'PDOException' 带有消息 'SQLSTATE[28000] [1045] Access denied for user 'tech'@'localhost' (using password: YES)' in ....
我可以在命令行中远程连接,但不使用 php,有什么想法可以看吗?
以下是详细信息:
Webserver A: 1.1.1.1 保存 php 脚本:
$REGIS_DB_SERVER = "2.2.2.2"; //I've tried the IP as well as "pretendhostname.com"
$REGIS_DB_NAME = "db_name";
$REGIS_DB_USER = "tech"; // or any other user name
$REGIS_DB_PASSWORD = "password";
//connect to db
$db = new PDO("mysql:host = $REGIS_DB_SERVER; dbname=$REGIS_DB_NAME; charset=utf8", $REGIS_DB_USER, $REGIS_DB_PASSWORD);
print_r($db -> errorInfo());
echo "Connected<br>";
$sql = "CREATE TABLE Test(PersonID int,LastName varchar(255),FirstName varchar(255),Address varcha(255),City varchar(255))";
$result = $db->query($sql);
echo "$result <br>";
?>
网络服务器 B:2.2.2.2 保存 mySQL 数据库:运行 Ubuntu 11.04
在 /etc/mysql/my.cnf
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#Commented out to allow remote connections to this database
#bind-address = 216.70.81.240
我运行mysql> select Host,User from user;
并得到:
+-----------------------+------------------+
| Host | User |
+-----------------------+------------------+
| % | root |
| 127.0.0.1 | root |
| 1.1.1.1 | tech |
| localhost | debian-sys-maint |
| localhost | root |
| localhost | tech |
+-----------------------+------------------+
在 ubuntu 12.04 中打开端口 3306 以允许从任何 ip 连接到 mysql意味着这不是 iptable 问题并测试连接:
我通过 ssh 进入 Webserver A 1.1.1.1 并运行:
mysql -u tech -p -h 2.2.2.2
Enter password:
