Movable Type is already doing my head in somewhat! First it took me forever to figure out why I couldn't add an entry. Now I can't delete! I click Rebuild Site and nothing happens. Why? Read the rest of this entry »

I had a real struggle getting Movable Type to work after I'd installed it. The problem, and the solution are described below (from a Movable Type Support Forum):

"Permission Denied" but permissions are 777, MT can't write files

alistairc Posted: Dec 1 2004, 02:51 PM   Group: Members Posts: 4 Member No.: 28429 Joined: 1-December 04 I've installed MT 3.1 Everything seems to be okay, except when I try to add an entry. The cgi files are installed in /var/www/cgi-bin/mt/ Other MT files are in /var/www/html/mt/ which I've blown wide open with chmod -R 777 /var/www/html/mt/ I have set NoTempFiles 1 in mt.cfg I created a new weblog, but when I edit the Core Setup and click Rebuild My Site I get: Writing to '/var/www/html/mt/index.html' failed: Opening local file '/var/www/html/mt/index.html' failed: Permission denied I don't understand this, as this directory has 777 permissions. Can anyone help? I've trawled about in Google but everything suggested has had not effect. I've tried deleting the weblog, deleting the mySQL database, re-running mt-load.cgi - but I get the same problem. shelley Posted: Dec 1 2004, 07:04 PM   Group: Six Apart Posts: 17192 Member No.: 22617 Joined: 8-November 01 Do you have an index.html that already exists in that folder? Perhaps try deleting it? alistairc Posted: Dec 2 2004, 04:10 AM   Group: Members Posts: 4 Member No.: 28429 Joined: 1-December 04 Nope, no index file in that folder. I did have the static files/folders there. I tried moving them elsewhere (and changing the config file) but I get the same error message when I try to rebuild: Writing to '/var/www/html/mt/index.html' failed: Opening local file '/var/www/html/mt/index.html' failed: Permission denied alistairc Posted: Dec 2 2004, 04:29 AM   Group: Members Posts: 4 Member No.: 28429 Joined: 1-December 04 I get the feeling this might be an Apache thing - something stopping CGI scripts writing files. I moved the CGI files from /var/www/cgi-bin/mt/ to /var/www/cgi-bin/ just in case Apache was particular about where Perl scripts are run from, but that didn't help - same error message. It seems like something is blocking mt.cgi from writing files, even though permissions are wide open. alistairc Posted: Dec 2 2004, 05:44 PM   Group: Members Posts: 4 Member No.: 28429 Joined: 1-December 04 OK, I finally found out what my problem was. I wasn't an Apache problem as such, but I was close. The problem was caused by using SELinux in Fedora Core 3. (I don't know what SELinux is, except that it's something to do with security. I'll be reading up on it in the very near future.) I found the answer while searching for help with another problem I was having (namely how to get past the error: "Can't connect to local MySQL server through socket /var/lib/mysql/mysql.sock" when trying to start up phpMyAdmin). Google led me to this page: http://groups-beta.google.com/group/alt.php.sql/...a983b3d20a60eda where the answer is: "adjust settings SELinux for httpd/apache" As soon as I read that I reckonned these two problems might have a common cause. Sure enough, once I'd disabled SELinux, both problems were solved. To disable SELinux (using the Gnome desktop), go to: Applications > System Settings > Security Level This opens the Security Level Configuration dialog box. Go to the SELinux tab and clear the selection on the check boxes: "Enabled (Modification Requires Reboot)" and "Enforcing Current: Permissive". You don't need to reboot, or restart httpd, the fix works as soon as you click OK. However, I'm not happy about having to disable something that was obviously designed to increase security (even if I don't know much about SELinux yet). And I don't much care for having a subdirectory of my html directory that has 777 permissions. But at least it all works now!

At some point, I really must get round to designing this weblog. There is some interesting information about using stylesheets on an MT blog here: http://weblog.burningbird.net/archives/2004/06/30/mary-janes-and-site-design/ I like the idea of being able to choose your preferred style, particularly if the site uses a cookie to remember the style you chose for next time you visit. But right now, I need to find out how to delete all the spam comments I've been getting. The standard design I chose for this blog when I set it up had a comment facility turned on. I didn't think it would get much use, but I thought there was no harm in having it there. WRONG! People set up irritating scripts that go around searching for weblog comment forms and post comments automatically with links to their sites (usually porn sites). Why? Well, when Google is working out how to rank sites found in a search it takes into consideration the number of other sites that link to the site. So the BBC get a high rank, because lots of sites contain links to the BBC website, but www.itauthor.com gets a low rank because (as of today) no one has linked to it. So far I've found out how to remove comments in MT if your blog is saved in a mySQL database, but mine isn't (my ISP doesn't allow it) so I need to keep looking. I will also remove the comments form. What I'm also looking for is a form that will email comments to me, so that I can vet them and add them to the blog if I choose. I could write this myself in Perl, but there must be an MT module out there that I can use.

The following link is nothing to do with technical authoring and only marginally anything to do with IT (in that it's a really nicely designed site – using MovableType): http://bigwhiteguy.com I stumbled upon this interesting (bloggish) site while writing a tender response for a possible customer out in Hong Kong. I wanted to use some plausible Chinese names in the search examples I'm including and Google threw up this site. Lovely design! It reminds me (again) that I really must get round to redesigning these pages.

Ignore this. I'm just testing Trackback to see what happens when I link to the previous entry (ITauthor notes: Trackback in Movable Type).
