I have setup Zope with ZEO on CentOS4.4, with the intention of running a Plone site. I previously used the same configuration to get Zope 2.9.3 with ZEO running on CentOS 3.7 * CentOS is setup without SELinux. * Python 2.5 is installed in /opt/python * Zeo starts fine, using /opt/zope/zeo/bin/zeoctl start I have created three zope instances in /opt/zope/pub0 /opt/zope/mem0 /opt/zope/sec0 When I try to start any of them, I get: [zope@centos4 zope]$ pub0/bin/zopectl start Traceback (most recent call last): File "/opt/zope/zope/lib/python/Zope2/Startup/zopectl.py", line 322, in <module> main() File "/opt/zope/zope/lib/python/Zope2/Startup/zopectl.py", line 280, in main options.realize(args) File "/opt/zope/zope/lib/python/Zope2/Startup/zopectl.py", line 91, in realize ZDOptions.realize(self, *args, **kw) File "/opt/zope/z2.9.6-p2.5/lib/python/zdaemon/zdoptions.py", line 273, in realize self.load_schema() File "/opt/zope/z2.9.6-p2.5/lib/python/zdaemon/zdoptions.py", line 321, in load_schema self.schema = ZConfig.loadSchema(self.schemafile) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/loader.py", line 31, in loadSchema return SchemaLoader().loadURL(url) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/loader.py", line 65, in loadURL return self.loadResource(r) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/loader.py", line 159, in loadResource schema = ZConfig.schema.parseResource(resource, self) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/schema.py", line 27, in parseResource xml.sax.parse(resource.file, parser) File "/opt/python/lib/python2.5/xml/sax/__init__.py", line 33, in parse parser.parse(source) File "/opt/python/lib/python2.5/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/opt/python/lib/python2.5/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/opt/python/lib/python2.5/xml/sax/expatreader.py", line 207, in feed self._parser.Parse(data, isFinal) File "/opt/python/lib/python2.5/xml/sax/expatreader.py", line 301, in start_element self._cont_handler.startElement(name, AttributesImpl(attrs)) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/schema.py", line 99, in startElement getattr(self, "start_" + name)(attrs) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/schema.py", line 475, in start_schema keytype, valuetype, datatype = self.get_sect_typeinfo(attrs) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/schema.py", line 201, in get_sect_typeinfo datatype = self.get_datatype(attrs, "datatype", "null", base) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/schema.py", line 194, in get_datatype return self._registry.get(dtname) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/datatypes.py", line 398, in get t = self.search(name) File "/opt/zope/z2.9.6-p2.5/lib/python/ZConfig/datatypes.py", line 423, in search package = __import__(n, g, g, component) File "/opt/zope/z2.9.6-p2.5/lib/python/Zope2/Startup/datatypes.py", line 21, in <module> import OFS.Uninstalled File "/opt/zope/z2.9.6-p2.5/lib/python/OFS/Uninstalled.py", line 20, in <module> import SimpleItem, Globals, Acquisition File "/opt/zope/z2.9.6-p2.5/lib/python/OFS/SimpleItem.py", line 26, in <module> import AccessControl.Role, AccessControl.Owned, App.Common File "/opt/zope/z2.9.6-p2.5/lib/python/AccessControl/__init__.py", line 17, in <module> from Implementation import setImplementation File "/opt/zope/z2.9.6-p2.5/lib/python/AccessControl/Implementation.py", line 98, in <module> setImplementation("C") File "/opt/zope/z2.9.6-p2.5/lib/python/AccessControl/Implementation.py", line 51, in setImplementation from AccessControl import ImplC as impl File "/opt/zope/z2.9.6-p2.5/lib/python/AccessControl/ImplC.py", line 18, in <module> from cAccessControl import rolesForPermissionOn, \ File "/opt/zope/z2.9.6-p2.5/lib/python/AccessControl/SimpleObjectPolicies.py", line 82, in <module> from DocumentTemplate.DT_Util import TemplateDict File "/opt/zope/z2.9.6-p2.5/lib/python/DocumentTemplate/__init__.py", line 21, in <module> from DocumentTemplate import String, File, HTML, HTMLDefault, HTMLFile File "/opt/zope/z2.9.6-p2.5/lib/python/DocumentTemplate/DocumentTemplate.py", line 112, in <module> from DT_String import String, File File "/opt/zope/z2.9.6-p2.5/lib/python/DocumentTemplate/DT_String.py", line 19, in <module> from DT_Util import ParseError, InstanceDict, TemplateDict, render_blocks, str File "/opt/zope/z2.9.6-p2.5/lib/python/DocumentTemplate/DT_Util.py", line 19, in <module> from html_quote import html_quote, ustr # for import by other modules, dont remove!
