plone4安装ZMySQLDA

我的安装环境：

系统：ubuntu10.04

plone版本：plone4.0

 

按该文档 http://xiaolin0199.iteye.com/blog/775118  的安装并没有错：

写道

1.编辑 buildout.cfg文件，在eggs=后面添加Products.ZMySQLDA

2.运行 sudo ./bin/buildout -v

3.运行后可看到安装成功信息，

MySQL-python = 1.2.3
Products.ZMySQLDA = 3.1

 

安装后，在zmi后台，并没有出现所谓的'Z MYSQL DATABASE CONNECTION'

 

google了下，欣然发现网上有类似的问题：

http://plone.293351.n2.nabble.com/Plone-4-ZMySQLDA-heartache-td5617267.html

 

解决方法：

 

1.编辑 buildout.cfg，除了eggs=后面添加Products.ZMySQLDA，还要将debug-mode设置成on(主要为了看到错误信息)

写道

eggs = ...
Products.ZMySQLDA

debug-mode = on

 

2.运行 sudo ./bin/buildout -v

写道

liwei@liwei-desktop:/usr/local/Plone/zeocluster$ sudo ./bin/buildout -v

 

 

3.启动plone后，发现打不开，查看相应日志文件/usr/local/Plone/zeocluster/var/client1/event.log

发现正是缺少这个gif才导致不能导入Products.ZMySQLDA

 

4.添加DBAdapterFolder_icon.gif

就是这个图： 

 

 

下载这个图片，直接放到 Plone/buildout-cache/eggs/Zope2-2.12.10-py2.6-linux-i686.egg/Shared/DC/ZRDB/www/ 下面即可。

再次访问plone，发现神奇的‘Z MYSQL DATABASE CONNECTION’出现了
