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>

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!!!
最新修改,为了方便日志的查看,在搜索的时候会将搜索的内容进行高亮显示,如上图。这个底层返回纠结了下子,因为要可以有星号。
