lighttpd and WordPress

admin — Wed, 08 Jun 2011 16:45:00 +0000

By default, lighttpd will not support your WordPress installation and it won’t give you any information about why not. It’s a total pain but here’s how to get it up and running.

lighttpd.conf
Make sure “mod_fastcgi” is enabled in the server.modules section.
Make sure you have the following lines:

fastcgi.server = ( “.php” => ((
“bin-path” => “/usr/bin/php-cgi”,
“socket” => “/tmp/php.socket”,
“max-procs” => 2,
“bin-environment” => (
“PHP_FCGI_CHILDREN” => “16″,
“PHP_FCGI_MAX_REQUESTS” => “10000″
),
“bin-copy-environment” => (
“PATH”, “SHELL”, “USER”
),
“broken-scriptfilename” => “enable”
)))

You may need to change some things around for your environment. Restart lighttpd and make sure it’s still working.
Try reloading your WordPress site, for example and you’ll likely see Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
You can solve this one of a number of ways. I just ran sudo apt-get install php5-mysql.
Restart lighttpd.
Assuming you have the correct database credentials, you should now be good to go. .

MyISAM table corruption causes

Even though the MyISAM table format is very reliable (all changes to a table made by an SQL statement are written before the statement returns), you can still get corrupted tables if any of the following events occur:

* The mysqld process is killed in the middle of a write.
* An unexpected computer shutdown occurs (for example, the computer is turned off).
* Hardware failures.
* You are using an external program (such as myisamchk) to modify a table that is being modified by the server at the same time.
* A software bug in the MySQL or MyISAM code.

MySQL has some additional documentation on this topic.

Forgotten MySQL Root Password

admin — Fri, 18 Jun 2010 11:35:45 +0000

It happens to the best of us all the time. (Three times in a 24-hour period is my record…) On my Ubuntu VPSs, this is what I do when that happens:
$-> /etc/init.d/mysql stop $-> mysqld_safe --skip-grant-tables & $-> mysql -u root
Use the ‘msyql’ database to issue this query:
UPDATE user set password=PASSWORD("ice_cream") where User='root';
Flush privs and then stop and start MySQL (normally).

Is MySQL OK?

There are always many ways to skin a cat but here’s a neat way to check on MySQL:

root@aleida:/home/aleida# mysqladmin -p ping Enter password: mysqld is alive

Kinda neat, no?
