| 91 |
If there is something wrong with your Apache, but you have no idea how to |
| 92 |
figure out what's wrong, your first clues will be in the log files. |
| 93 |
</p> |
| 94 |
|
| 95 |
<p> |
| 96 |
There are a few log files around. All of them are located inside |
| 97 |
<path>/var/log/apache2/</path>. Not all of the following log files will be |
| 98 |
on your system: this depends on what modules you have enabled. |

As you can see, this file can contain a lot of stuff, depending on the |
| 178 |
<c>ErrorLevel</c> directive in your <path>httpd.conf</path> file. It tells you |
| 179 |
if apache started up correctly, what errors it has run into, ... In general it |
| 180 |
will tell you what went wrong. If something isn't working right, this should |
| 181 |
be the first file you check for more information. |

<title>I installed a module, but it's not working!!!</title> |

Just installing a module is not enough - you have to explicitly turn it on. We |
| 213 |
do this so that it's easy to turn on and off individual modules, which makes |
| 214 |
it easy to find which module is causing problems and let's you test |
| 215 |
modules and disable them easily. |
| 216 |
</p> |
| 217 |
|
| 218 |
<p> |
| 219 |
When you install a module, it should display a message similar to this: |
| 220 |
</p> |
| 221 |
|
| 222 |
<pre caption="Post-installation message from emerge"> |
| 223 |
* |
| 224 |
* To enable mod_layout, you need to edit your /etc/conf.d/apache2 file and |
| 225 |
* add '-D LAYOUT' to APACHE2_OPTS. |
| 226 |
* |
| 227 |
* |
| 228 |
* Configuration file installed as |
| 229 |
* /etc/apache2/modules.d/15_mod_layout.conf |
| 230 |
* You may want to edit it before turning the module on in /etc/conf.d/apache2 |
| 231 |
* |
| 232 |
</pre> |
| 233 |
|
| 234 |
<p> |
| 235 |
This is pretty straightforward. It tells you exactly what you need to do to |
| 236 |
enable this module. |
| 237 |
</p> |
| 238 |
|
| 239 |
<p> |
| 240 |
If you missed this message, there is another way to find out what you need to |
| 241 |
add to <c>APACHE2_OPTS</c> in <path>/etc/conf.d/apache2</path>: simply |
| 242 |
check the configuration file the module installed. The module's |
| 243 |
configuration file should be added to <path>/etc/apache2/modules.d/</path>. |
| 244 |
Look for it there and find a line that has <c>IfDefine</c>: |
| 245 |
</p> |
| 246 |
|
| 247 |
<pre caption="An excerpt from 15_mod_layout.conf"> |
| 248 |
<IfDefine LAYOUT> |
| 249 |
<IfModule !mod_layout.c> |
| 250 |
LoadModule layout_module modules/mod_layout.so |
| 251 |
</IfModule> |
| 252 |
</IfDefine> |
| 253 |
</pre> |
| 254 |
|
| 255 |
<p> |
| 256 |
The <c>IfDefine</c> block is ran when you add <c>-D LAYOUT</c> to |
| 257 |
