+====Symbolic Links====
+By default symbolic links may not work on Apache on CentOS. Assuming the symlink we are considering points to /example, then use the following command. This will add the appropriate SELinux context to the /exampledirectory and all its contents
+<code>chcon -Rv --type=httpd_sys_content_t /example</code>
+Replace <code>httpd_sys_content_t</code> with <code>public_content_t</code> if you want it to work with ftp as well.
+====XAuth====
+When using an xauth, you may get this error
+<code>ERROR = /usr/bin/xauth:  timeout in locking authority file /home/username/.Xauthority</code>
+The solution is to fix the SELinux permissions
+<code>chcon unconfined_u:object_r:user_home_dir_t:s0 /home/username</code>
+====Allow Perl to Connect To MySQL====
+Run this command to allow Perl to connect to Database server while still having SELinux enabled.
+<code>semanage boolean -m --on httpd_can_network_connect_db</code>
