操作系统：Linux wiki 2.6.32-131.0.15.el6.x86_64

nginx版本： nginx-1.5.7 

uwsgi版本：uwsgi-2.0.8

大致流程参考：http://www.linuxyw.com/353.html

(官方文档：http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html)

下面主要介绍安装过程中出现的几个问题

1. uwsgi安装中，由于openssl 源码升级过导致的问题

ssl.c:(.text+0x4a4): undefined reference to `EC_KEY_new_by_curve_name‘ssl.c:(.text+0x4e6): undefined reference to `EC_KEY_free‘collect2: error: ld returned 1 exit status*** error linking uWSGI ***make: *** [all] Error 1

 常叔说是由于找到了头文件，但是没有找到头文件的函数的定义导致的，google一把，果然如此：

From the error shown it looks like you have new openssl headers but still old libssl.so library in the library path. Make sure to remove old openssl library (and install new library if there are no new libssl.so available).  http://trac.nginx.org/nginx/ticket/169

下面问题似乎明朗了，由于我之前给openssl升级过，升级命令如下：

./config --prefix=/usr/ --openssldir=/usr/local/opensslmakemake testmake install

 再看下系统现在rpm包的安装情况和调用的动态链接库的情况：

root@192.168.100.252:/data/installs/uwsgi-2.0.8# rpm -qa | grep openssl openssl-1.0.0-10.el6.x86_64openssl-devel-1.0.0-10.el6.x86_64openssl098e-0.9.8e-17.el6.x86_64root@192.168.100.252:/data/installs/uwsgi-2.0.8# ll /usr/lib64/ | grep ssl lrwxrwxrwx.  1 root root       27 Aug 20 01:15 libnss_compat_ossl.so.0 -> libnss_compat_ossl.so.0.0.0-rwxr-xr-x.  1 root root    84672 Mar 17  2010 libnss_compat_ossl.so.0.0.0-rwxr-xr-x.  1 root root   215792 Apr 22  2011 libssl3.so-rw-r--r--   1 root root   676230 Jan 22 12:52 libssl.alrwxrwxrwx.  1 root root       21 Aug 20 01:17 libsslcommon.so.5 -> libsslcommon.so.5.0.0-rwxr-xr-x.  1 root root   209904 Apr  6  2011 libsslcommon.so.5.0.0lrwxrwxrwx.  1 root root       15 Aug 20 01:15 libssl.so -> libssl.so.1.0.0-rwxr-xr-x.  1 root root   324680 Apr 21  2010 libssl.so.0.9.8elrwxrwxrwx.  1 root root       15 Aug 20 01:14 libssl.so.10 -> libssl.so.1.0.0-rwxr-xr-x.  1 root root   374128 Feb 10  2011 libssl.so.1.0.0lrwxrwxrwx.  1 root root       16 Aug 20 01:19 libssl.so.6 -> libssl.so.0.9.8edrwxr-xr-x.  3 root root     4096 Aug 20 01:14 openssldrwxr-xr-x.  3 root root     4096 Aug 20 01:19 openssl098e

 稍等，那个1098e的rpm包应该可以先删掉了。。rpm -e openssl098e-0.9.8e-17.el6.x86_64

不行啊，这样还是找不到问题的根源，先找出我的虚拟机244，在上面装一把看看，内网服务器别搞崩溃了

244的小机器也是一样的openssl升级方法，安装uwsgi完全没报错，这下真迷惑了，继续google

http://www.111cn.net/sys/CentOS/61326.htm 大牛说需要加一个参数 shared zlib-dynamic

再次make clean ; ./config --prefix=/usr/ --openssldir=/usr/local/openssl shared zlib-dynamic ; make 还是报错

 好熟悉的感觉，可能是源码被污染了，删掉重来。。

2. nginx安装，这个比较简单，就不介绍了

cd /data/var/nginx-1.5.7./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-pcre=/data/var/pcre-8.11 --with-openssl=/data/installs/openssl-1.0.0m/  makemake install

 3. uwsgi配置

 3.1 参照官方文档，先写一个test.py测试一下uwsgi运行情况

root@192.168.100.252:/usr/local/nginx# cat /data/forilen/Kikyou/Kikyou_web/test.py def application(env, start_response):    start_response(‘200 OK‘, [(‘Content-Type‘,‘text/html‘)])    #return [b"Hello World"] # python3    return ["Hello World"] # python2

 启动uwsgi

 3.2 再用uwsgi重新启动项目Kikyou_web，下面的Kikyou_web.wsgi不用存在

3.3 配置/usr/local/nginx/conf/nginx.conf，添加django资源处理配置部分

    server {        # the port your site will be served on        listen 8090;        server_name localhost;        charset     utf-8;        # max upload size        client_max_body_size 75M;   # adjust to taste        # Django media        location /media  {            alias /data/forilen/Kikyou/Kikyou_web/media;  # your Django project‘s media files - amend as required        }        location /static {            alias /data/forilen/Kikyou/Kikyou_web/static; # your Django project‘s static files - amend as required        }        # Finally, send all non-media requests to the Django server.        location / {            uwsgi_pass  django;            include     /usr/local/nginx/conf/uwsgi_params; # the uwsgi_params file you installed        }    }

 reload nginx配置，浏览器访问请求资源

3.4 修改nginx.conf

    upstream django {        server unix:///usr/local/nginx/uwsgi.sock; # for a file socket        #server 127.0.0.1:8001; # for a web port socket (we‘ll use this first)    }

 启动项目：root@192.168.100.252:/usr/local/nginx# uwsgi --socket /usr/local/nginx/uwsgi.sock --module Kikyou_web.wsgi --chmod-socket=664

此时只有静态页面可以访问 >_<

3.5 添加文件/usr/local/nginx/conf/uwsgi.ini

# uwsgi.ini file[uwsgi]# Django-related settings# the base directory (full path)chdir           = /data/forilen/Kikyou/Kikyou_web# Django‘s wsgi filemodule          = Kikyou_web.wsgi# the virtualenv (full path)# home            = /path/to/virtualenv# process-related settings# mastermaster          = true# maximum number of worker processesprocesses       = 2# the socket (use the full path to be safesocket          = /usr/local/nginx/uwsgi.sock# ... with appropriate permissions - may be needed# chmod-socket    = 664# clear environment on exitvacuum          = true

 root@192.168.100.252:/usr/local/nginx# uwsgi --ini /usr/local/nginx/conf/uwsgi.ini 

reload nginx，再次访问，此时静态页面和动态页面都能正常访问。。^_^
