ajp1.3 config

[11年前 に gordon daniels によって更新されました。]

Could someone tell me if this config for port redirect is proper? I am having 503 errors after server runs for a while. Also, I commented out port 8080 in server.xml file. Is that proper?

thanks

<VirtualHost *:80>
ServerAdmin [e-mail]
ServerName example.com
ServerAlias www.example.com
Rewriteengine On
ErrorLog "/var/log/httpd/ajp.error_log"
CustomLog "/var/log/httpd/ajp.access_log" common
<Directory />
Options FollowSymlinks
AllowOverride None
</Directory>

ProxyPass / ajp://localhost:8009/
ProxyPassReverse / ajp://localhost:8009/
</VirtualHost>

bump: My server shutdowns after being up for about eight hours. I see this in the apache log:

[error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header

So, I was hoping someone could tell me if the above config is wrong.

Pretty sure that's wrong, don't see a need for the reverse for one and you probably only see proxy of unsecured requests on port 80 for another. I'd take it off the virtualhost and put in it's own scrap in /etc/httpd/conf.d/ like;

echo "# ajp proxy configuration
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
ProxyPass / ajp://localhost:8009/
" > /etc/httpd/conf.d/proxy_ajp.conf

and proxy everything.

Linus: thanks for the reply. Yes, that does not work. I installed mod_jk and configured it. It works great.

thanks again for taking the time to help

This was a while ago, and it looks like there was a workaround with mod_jk, but just in response, I had configured mod_proxy_ajp as below, with the actual server hostnames replaced by example.com:

<VirtualHost *:80>
ServerName example.com
<Proxy *>
Allow from all
</Proxy>
ProxyPass / ajp://example.com:8009/
</VirtualHost>

Also, commenting out 8080 in the Tomcat server.xml shouldn't be an issue, although I've never done it. I've found accessing the Tomcat server directly can be helpful for troubleshooting.

Jack: thanks. I had just read recently that approach might work. I really appreciate you sharing. I'm going to give it a try. BTW, mod_jk works really well but not as easy to configure I think as ajp.

Generally, the preferred method, or so I'm told, is to use mod_jk. Sometimes, there is the additional configuration, or even a compilation of the module itself on *nix systems, but for the most part, mod_jk has more flexibility than mod_proxy_ajp. You may want to experiment with the jkstatus and jkmanager page on some sandbox systems. It allows realtime manipulation of the ajp workers.

Jack: thanks for the input. Will give it a try. Really appreciate you taking the time.
