mysql_connect prompts 'No such file or directory' error_PHP tutorial

Some friends will get the No such file or directory error message when using mysql connection. Let me summarize the solutions below.

Connection code

2. Write a phpinfo page and find mysql.default_socket, mysqli.default_socket, and pdo_mysql.default_socket. 3. Start mysql and execute the command STATUS; note the value of the UNIX socket.

The code is as follows  代码如下 复制代码 $this->linkid = @mysql_pconnect($host, $user, $password) or die(mysql_error());

Copy code

$this->linkid = @mysql_pconnect($host, $user, $password) or die(mysql_error()); Make a phpinfo() page. Look for ‘mysql.default_socket‘, ‘mysqli.default_socket‘, and ‘pdo_mysql.default_socket‘. Remember their value; this is where PHP is trying to connect to MySQL. Solution 1. First of all, it is determined that it is a problem with mysql_connect() and mysql_pconnect(). The fault phenomenon is that the function returns empty and mysql_error() returns "No such file or directory".

4. If the values ​​​​of 2 and 3 are different, open php.ini (the location of php.ini can be found from the phpinfo page, the default is /private/etc/php.ini)

, change the values ​​of the three configuration items mentioned in 2 to the values ​​of 3.
