Thank you for your interest in Piwik. However, we can’t provide this level of MySQL support. Please try the MySQL forums.

If I edit the config/config.ini.php and put double-quotation marks around the host line:

```
host = “localhost;unix_socket=/home/myusername/mysql/socket”
```

then Piwik can connect to the MySQL server. However, when Piwik rewrites the configuration file it quickly reverts back to:

```
host = localhost;unix_socket=/home/myusername/mysql/socket
```

which is parsed as:

```
host = localhost
```

Line 128 of core/Config.php indicates you’ve already dealt with this problem for another key. Please encapsulate any field with an embedded ; character. My proof-of-concept looks like this:

```
if (strpos($value, ‘;’) !== false) {
$value = ‘"’.$value.‘"’;
} else
```

although I’d recommend that Piwik actually escape values and handle strings of any type.

Rolled requirements into #481 (username should be in quotes).

thanks
