我在一个网站上安装了Plone 4.3.3。首先,buildout配置为使用var / filestorage中的Data.fs文件和var / blobstorage中的共享blob存储。然后我在buildout中添加了一个Relstorage,并将Data.fs文件的内容转换为底层的MySQL数据库。现在Plone正在使用Relstorage而不是Data.fs。
但是现在我还想使用Relstorage而不是blobstorage。因为我对Plone而言比较新,特别是Relstorage的东西,我的想法是首先设置一个新的空Plone。然后我将buildout.cfg和base.cfg从第一个复制到新的。然后我创建了一个新的数据库userZodb并更改了base.cfg以使用新数据库,我还更改了zeoserver和clients的端口。下一步是重新配置relstorage而不使用基于文件的blobstorage。
rel-storage =
type mysql
db userZodb
user zodbuser
passwd innzop
blob-dir ${buildout:var-dir}/blobstorage
shared-blob-dir false
# shared blobs are much faster if we're on the same server.
# if not, turn it off.
shared-blob = off
然后我跑了扩建。一切都建成了。启动zeoserver后,我从客户端收到此错误:
user@server:~/Plone433-dev/zeocluster3$ ./bin/zeoserver start
.
daemon process started, pid=35136

不幸我不知道问题出在哪里。有人建议吗? 谢谢!

如果你正在使用relstorage
,blob目录仍然用于缓存(Check for more infos)。在您的情况下,您的目录布局存在问题。
您可以删除$ {buildout:directory}中的洞var
目录并重新运行buildout。
这将创建一个新的var目录。启动实例后,您应该有一个具有正确布局的新blob目录。
OR
您可以修改$ {buildout:directory} / var / blobstorage中的.layout
文件,并将值从bushy
更改为zeocache
说明:
第一次启动Plone实例时,它会使用给定的布局创建blobstorage目录 - 在您的情况下,它是默认的bushy
。由于您更改了存储空间,因此需要zeocache
。但标记文件.layout
不会自动更改。
如果这没有帮助,请发布完整的buildout.cfg。

解决方案是再次使用zodbconvert。正确配置它可以从一个存储转换为另一个存储,例如从Blobstorage到Relstorage。在我的情况下,配置看起来像:
<filestorage source>
path /home/user/Plone433-dev/zeocluster/var/filestorage/Data20141230.fs
blob-dir /home/user/Plone433-dev/zeocluster/var/blobstorage
</filestorage>
<relstorage destination>
shared-blob-dir false
# ZODB Cache Dir
blob-dir ./var/cacheblob
blob-cache-size 10mb
<mysql>
host localhost
db Zodb
user zodbuser
passwd XXXXXXXXX
</mysql>
</relstorage>
之后,您必须更改base.cfg和buildout.cfg以仅使用relstorage。您可以在此处找到有关其运作方式的更多信息:https://www.techidiots.net/notes/plone-1/plone-4-3-3-relstorage
