openstack日志汉化

openstack日志已经有汉化的模块，只需要做一些配置已经bug修复

1.配置nova.conf

log_config_append=/etc/nova/logging.conf

2.配置logging.conf

[loggers]

keys = root,compute

[formatters]

keys = context,default

[logger_root]

level = NOTSET

handlers = translator

[logger_compute]

handlers = translator

qualname = nova-compute

[handlers]

keys = translatedlog, translator

[handler_translatedlog]

class = handlers.WatchedFileHandler

args = ('/var/log/nova/compute.log',)

formatter = context

[handler_translator]

class = nova.openstack.common.gettextutils.TranslationHandler

target = translatedlog

args = ('zh_CN',)

level = INFO

[formatter_context]

format = %(asctime)s.%(msecs)03d %(process)d %(levelname)s %(name)s %(roles)s [%(request_id)s %(user)s %(tenant)s] %(message)s

[formatter_default]

format = %(asctime)s.%(msecs)03d %(process)d %(levelname)s %(name)s [-] [-] %(message)s

3.配置环境变量或者使用默认的/usr/share/locale/

如果没有配置环境变量，代码里会默认找该文件

/usr/share/locale/zh_CN/LC_MESSAGES/nova.mo

4.生成mo文件

mkdir -p /usr/share/locale/zh_CN.gb2312/LC_MESSAGES/

cd /usr/lib/python2.6/site-packages/nova/locale/zh_CN/LC_MESSAGES/

msgfmt --statistics --verbose -o nova.mo nova.po 

ln -s /usr/lib/python2.6/site-packages/nova/locale/zh_CN/LC_MESSAGES/nova.mo /usr/share/locale/zh_CN/LC_MESSAGES/nova.mo

5.修改bug

/usr/lib/python2.6/site-packages/nova/openstack/common/gettextutils.py
