之前已经有域名为aaa.bbb.com的网站，现在想在aaa.bbb.com/bbs/下建一个Discuz X2.5，然后在aaa.bbb.com/tomcat/下建一个java程序。服务器的环境是LNMP，配置的过程中需要不断地学习Nginx，下面做一个简要的整理。

=========================   搭建 Discuz X 2.5   ================================

参考：http://blog.163.com/cobyeah@126/blog/static/140137653201151815916438/

- 系统： Ubuntu 10.04   |  all Linux
- 软件： nginx 0.7.65

说实话我并不十分了解wordpress，但看着网上的教程设置nginx的配置就觉得无奈，nnd他们到底研究过nginx的没有啊？！
if/rewrite的一大堆，需要么？

下面是我的方案，简单得很！

location /wp/ { 
        index  index.php; 
        try_files $uri $uri/ /wp/index.php?$args; 
    } 

wp是wordpress的目录 

够简单吧？

Python版本3.6

测试语句：

select * from FOO;

mysql终端直接执行:

46410 rows in set (0.10 sec)

python程序需安装profilehooks进行调用耗时分析

pymysql驱动测试程序：

# 安装：pip install pymysql

from profilehooks import profile
import pymysql.cursors
import pymysql
connection = pymysql.connect(host='localhost', user='root', db='foo')
c = connection.cursor()

@profile(immediate=True)
def read_by_pymysql():
    c.execute("select * from FOO;")
    res = c.fetchall()
