Note my favicon:

I had been meaning to add a favicon (note the icon next to my address in the address bar on your browser) for quite some time, but hadn’t gotten around to it. The last time I tried to create something in the .ico format, I needed a special tool.

But then again, times change. I used the GIMP to make the .ico file and posted it to the root of my webserver directory.

Nothing happened when I refreshed the page.

Then I found out that I needed to tell Apache about .ico files, so I put the following in my /etc/httpd/conf/httpd.conf file:

AddType image/x-icon .ico

Make sure that the favicon.ico file has the executable bit set for everyone:

chmod a+x

and now it will show up.

You might need to clean out your cache and restart your browser to see it. Evidently this feature "sticks" to web pages.

I’ve been using makeself from http://megastep.org/makeself/.

This is an excellent tool for distributing self-extracting executables.

There is one issue that was not apparent to me. You can tell the resulting script to execute a file within the archive after extraction. Hence, the following will run test.sh after setup extracts everything:

./makeself.sh --compress ~/tmp setup "Test Installation Setup" ./test.sh

./test.sh is what is extracted. The leading ./ is necessary because the file is executed relative to the extracted directory.

If the Tikiwiki install generates a blank screen, it could be (it was for me) because you don’t have the php-mysql package installed.

CentOS 5 does not install the php-mysql package by default.

This is required by Tikiwiki if you are using mysql (obviously).

Setting up user directories for Apache (i.e. ~user) on CentOS 5:

1. Change the /etc/httpd/conf/httpd.conf and comment out:

   UserDir disable

   and un-comment:

   UserDir public_html

2. Restart Apache.
3. Create a public_html directory in the user’s home directory.
4. Make sure it has permissions 0755.
5. Make sure their home directory has permission 0711.
6. Make sure that public_html directory has SELinux context:

   user_u:object_r:httpd_sys_content_t

7. Make sure that the SELinux boolean

   httpd_enable_homedirs

   is set to "on".

Configuring CentOS 5 host for sharing home directories over samba.

Create a samba user:

smbpasswd -a smjones

Start Samba:

/sbin/service smb start

Make sure it will start on next boot:

/sbin/chkconfig --level 2345 smb on

Make sure SELinux doesn’t stop us from sharing home directories:

/usr/sbin/setsebool -P samba_enable_home_dirs on
