I am trying to install wordpress into my system at fedora 17. I am getting error with database connectivity:

Error establishing a database connection

I have done below troubleshooting.

  1. I have tried with command prompt to connect mysql database with same credentials and its connected successfully.

  2. Than I tried to connect to database directly using php using below code.

    <?php
$db = @mysql_connect('localhost', 'wpuser', 'wppassword');
if (!$db) echo "connection failed --". mysql_error();
else echo "connection succeeded";
?>

I received error:

connection failed --No such file or directory

Than I have recompiled php with apache2 and mysql than the same code is throwing error:

connection failed --The server requested authentication method umknown to the client

mysql conf file is as below.

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

also at php.ini I have set 

mysql.default_socket = /var/lib/mysql/mysql.sock

Please let me know how to proceed further.I am still getting the same error for wordpress.

第一个错误

没有这样的文件或目录

是因为mysqld.sock文件路径不对。这可能已经修复，因为您稍后会指出您收到的另一个错误是

服务器请求客户端未知的身份验证方法

此错误已在 ServerFault 上进行了解释

MySQL 在（我认为）4.1 版中引入了更长的密码哈希，您的服务器可能仍在使用它们（检查 mysql 用户表中的 16 字节密码哈希）。较新的版本使用较长的密码哈希。您的服务器同时支持两者，但您的客户端 (php) 似乎只支持此版本（及更高版本）中的新客户端。

如果可能，请使用第一行链接中的解决方案，并使用新哈希再次设置密码，但请注意，如果您使用的任何其他（旧）客户端依赖于旧密码，兼容性可能会中断。还尝试在 PHP 中寻找对 MySQL 的旧密码支持，但我不确定。
