While we're working on trying to find alternate solutions, we've decided to go back to Zope 2.6.0 to serve the data in the system we've developed over the last year and a half. We took a box, running RedHat 9, and installed Zope 2.6.0 as follows: Install directory: /usr/local/zprod python: # export CC="gcc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/kerberos/include" # ./configure --prefix=/usr/local/zprod/python --with-threads # make # make install Zope: # cd /usr/local/zprod # tar -zxvf /web/zsup/src/Zope-2.6.0-src.tgz # mv Zope-2.6.0-src Zope-2.6.0 # ln -s Zope-2.6.0 zope # chown -R apache:zopeadmins Zope-2.6.0 # cd zope # su apache -s /bin/sh -c "/usr/local/zprod/python/bin/python2.1 ./wo_pcgi.py" # /usr/local/zprod/python/bin/python2.1 ./zpasswd.py inituser and testrun: # su apache -s /bin/sh -c "./start" Works like a charm. We used the exact same steps for Zope 2.6.4. FTP downloads run at 10k/sec. Anyone see any problems with this? Anyone else using RedHat 9? We're going to try an install on Debian tomorrow. Ed
