I have to say, my server is performing beyond my initial expectations! I think I have everything tweaked to not use massive amounts of RAM (coughMySQLcough.) Here’s how the free -m currently looks: $ free -m total used free shared buffers cached Mem: 121 90 31 0 2 46 -/+ buffers/cache: 41 80 Swap: 1121 14 1107 As you can see, it’s doing pretty good. I’ve even upped the maximum simultaneous Apache connections since it seems to be able to handle that a better now (rather then bringing the server to its knees when something like 10-15 people tried to access it at once.
So, I recently set a link to my discussion of Linux, GNU, and OS’s to someone on Identi.ca. I made a point not to add groups to !linux and !gnu because I knew my server would probably get hit hard (if you’ve looked at my server’s specs, you’ll know it doesn’t take much to be considered hit hard.) Well, they read it, after which they posted a link to my blog with the groups !
So, I’ve only been up for about three weeks and I’ve already got my first spam comment (which is why I moderate all comments ATM.) Also, it was kind of strange, I went to go here at work today and I wasn’t able to connect. So, I logged into my router. I thought that my iptables were screwy again, so I started trying to fix them by hand. Deleted a rule and BAM no more connectivity to my router (at all.
Well now that the system is live, I think there’s going to be a few things I’m going to need to fix. Most all of them are from using mod_chroot. Most aren’t anything critical, but things that should be addressed (sooner rather than later.) For instance, I think DNS lookups are failing from inside WordPress. I breifly read in the mod_chroot caveates that this may happen, and I think this is happening now.
Well, my server is pretty much ready I now. Apache is chrooted and seems to be working well. I also did a self-signed cert in hopes that’ll make my remote logins even more secure to WordPress. SSH access is limited to keyed logins. Ntpd is running in hopes of keeping the system’s clock sane. I’ve moved all my Git repos here and even have my CGit vhost running/working. Git daemon is also running.
As I prepare to have my server public, I’ve chrooted my server’s Apache with mod_chroot. This allows me to have the advantages of a chroot environment without as many of the draw backs. There is still some strangeness to work out. For instance “Warning: timezone_open() [function.timezone-open]: Unknown or bad timezone (America/Chicago) in /wp/wp-includes/functions.phpon line 3160” I’ll get this figured out, but honestly, it’s not a huge deal. I may have to have Apache load the zoneinfo file, or perhaps not… Really, the only change I had to make to WordPress was to have it connect to the MySQL database on 127.
