Looking to redirect path /blog to another server using Apache - apache

Question

I want to host my blog on it's own server, but have the URL be at mysite.com/blog
Should I do this using mod_proxy or an apache redirect, and how would I set this up on apache?
My first pass attempt looks like so in the vhost file, but failed:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass /blog http://blog.server's.ip.address/
ProxyPassReverse /blog http://blog.server's.ip.address/
ServerAdmin me#myemail.com
ServerName mysite.com
DocumentRoot /var/www
<Directory /var/www>
Order allow,deny
allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
With this is place I get the following error when restarting apache:
Restarting web server apache2 /sbin/start-stop-daemon: warning: failed to kill 11306: Operation not permitted
[fail]
The apache2 configtest failed, so we are trying to kill it manually. This is almost certainly suboptimal, so please make sure your system is working as you'd expect now!

Answer 1

mod_proxy needs to be enabled before working >_<
Once I enabled it my config worked as expected.
a2enmod proxy_http
