How do I downgrade from apache 2 back to apache 1.3?

If you need to go back to apache 1.3 after installing apache 2, you’ll need to do the following:

1) Restore the old httpd.conf file:

cp -f /etc/httpd/conf/httpd.conf.1.3.backup /etc/httpd/conf/httpd.conf


2) Get DirectAdmin to use the old httpd.conf files for the users. Edit the /usr/local/directadmin/conf/directadmin.conf file and change apache_ver=2.0 to apache_ver=1.3. Then type

echo "action=rewrite&value=ips" >> /usr/local/directadmin/data/task.queue
echo "action=rewrite&value=httpd" >> /usr/local/directadmin/data/task.queue
echo "action=directadmin&value=restart" >> /usr/local/directadmin/data/task.queue

3) Now you can recompile apache 1.3

rm -f /usr/lib/apache/*
cd /usr/local/directadmin/customapache
./build clean
./build all

4) Fix the modules link:

cd /etc/httpd
rm -f modules
ln -s /usr/lib/apache modules


5) Restore the old boot script:
FreeBSD:

cp -f /usr/local/directadmin/customapache/httpd_freebsd /usr/local/etc/rc.d/httpd
chmod 755 /usr/local/etc/rc.d/httpd
/usr/local/etc/rc.d/httpd restart


RedHat:

cp -f /usr/local/directadmin/customapache/httpd /etc/init.d/httpd
chmod 755 /etc/init.d/httpd
/etc/init.d/httpd restart
