django+nginx+xshell简易日志查询,接上<关于《rsyslog+mysql+loganalyzer搭建日志服务器<个人笔记>》的反思>
纠正一下之前在<关于《rsyslog+mysql+loganalyzer搭建日志服务器<个人笔记>》的反思>中说到的PHP+MySQL太慢，这里只是说我技术不好，没有技术可以修改这个开源的php日志程序罢了，当然，在做这个的时候，也是菜鸟一个，只是想自己尝试一下。高手可以直接跳过.....
首先，写在前面，因为上班空闲时间不多，只有忙里偷闲或自己回家的时间弄下，所以这个前后的时间就比较久了。
之前在上篇写到，是准备使用apache+django来搭建的，但是真的，我折腾了几次apache+wsgi的，我始终没有成功，无耐，我就没有再使用这个了。最终改为使用nginx+django来进行环境的搭建，这个搭建的相关的教程，如有意向的同学可以看这个.<nginx+uwsgi<django web环境的搭建>,个人感觉使用nginx+uwsgi，搭建的速度更快，而且几乎不用考虑什么版本的问题。真心为自己之前准备使用apache+wsgi而心痛自己。但是不得不说，有之前的经历所以看到这个nginx+uwsgi的思路，也一下子就清楚需要怎么操作了。
然后其它的就是一些代码相关的了，这里也当是记录下自己的搭建的步骤吧！大晚上的写得详细些吧！
首先是settings.py的文件：<导入log,还有最底下面的静态路径的设置，这里稍微注意一下>

urls.py<就几个url,没有什么特殊的>,好吧,我不得不说,那个The Django Book 我只看了下前面的7章,而且还不认真.<http://djangobook.py3k.cn/2.0>
from django.conf.urls import include, url from django.contrib import admin from log import views from django.conf import settings urlpatterns = [ url(r‘^admin/‘, include(admin.site.urls)), url(r‘^$‘,views.login), url(r‘^login/$‘,views.login), url(r‘^loginsuccess/$‘,views.loginsuccess), url(r‘^logout/$‘,views.logout), ]
log/views.py--------现在目前还没有加上一些判断之类的.比较菜.只是简单的.

恩，好吧，大概就是这样一个页面的东西了，没有什么其它的东西了！回想起来还是非常简单的，最麿人的事情是在apache+wsgi的时候，好了！那都是后话了，这样试了下，每天大概有几百M的日志，这样查没有什么问题，响应速度还是不错的。好吧，是好垃圾个，暂时时间与能力有限，先这样，后面再慢慢的进行修改优化下！！！
