Question

我有两个服务器名为server1和server2.both有不同的静态IP地址。我想从server1访问server2数据库。我安装了PHPmyadmin.In Server1操作系统是Ubuntu，在server2 fedora12。

我已经完成了这个..mysql错误13即将到来

server2中的

my.cnf包含

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0
# To allow mysqld to connect to a MySQL Cluster management daemon, uncomment
# these lines and adjust the connectstring as needed.
#ndbcluster
#ndb-connectstring="nodeid=4;host=localhost:1186"
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[ndbd]
# If you are running a MySQL Cluster storage daemon (ndbd) on this machine,
# adjust its connection to the management daemon here.
# Note: ndbd init script requires this to include nodeid!
connect-string="nodeid=2;host=localhost:1186"
[ndb_mgm]
# connection string for MySQL Cluster management tool
connect-string="host=localhost:1186"

Answer 1

首先，您需要在MySql Server2上启用远程访问。

然后你就可以这样做：

mysql_connect("xxx.xxx.xxx.xxx", "username", "password") or die(mysql_error());

Answer 2

如果您的问题是与远程mysql数据库的连接，那么您可以尝试以下代码：

$link = mysql_connect('example.com:3307', 'mysql_user', 'mysql_password');

曾为我工作过一次！

Answer 3

尝试使用以下内容在connect_server2.php上创建server1文件：

<?
    $server2 = '1.2.3.4'; // the IP of server2
    echo mysql_connect($server2, 'username', 'password') ? 'you have been connected' : 'cannot connect to server2';
?>

Answer 4

这取决于您希望如何访问server2上的数据库。

假设你只是想通过mysql客户端连接试试这个：

mysql -h <server2ip or hostname> -u <username> -p

在提示时输入密码。

如果你想通过php尝试这样的话，用server2中的ip替换server_ip，用mysql server2中的值替换username和password：

<?php
$link = mysql_connect('server_ip', 'user', 'password');
 if (!$link) {
die('Error connecting to db: ' . mysql_error());
}
echo 'Successful conntected to database';
mysql_close($link);
?>

我想将一个服务器数据库连接到另一个服务器
