Nginx8.x+uWSGI驱动 Trac

环境: CentOS 5.5 + Python2.6 + Nginx 0.8.54 + KTRAC 1.0(基于trac 0.11)

愿望

使用 Nginx+uWSGI 高效发布

思路

安装 uWSGI 服务器
用 uWSGI 带动 KTRAC 运行
通过 Nginx 的mod_uwsgi 发布

安装 uWSGI

# cd /data/app/_src
# wget http://projects.unbit.it/downloads/uwsgi-0.9.6.5.tar.gz
# tar xzvf...
# cd uwsgi-0.9.6.5
# make
    *** uWSGI linking ***
gcc -pthread -o uwsgi  utils.o pyutils.o protocol.o socket.o logging.o wsgi_handlers.o wsgi_headers.o uwsgi_handlers.o plugins.o main.o uwsgi_pymodule.o async.o nagios.o ini.o proxy.o http.o snmp.o sendfile.o xmlconf.o spooler.o -lpthread -rdynamic -lpthread -ldl -lutil -lm -lpython2.6 -L/usr/local/lib -lxml2 -lz -liconv -lm
*** uWSGI is ready, launch it with ./uwsgi ***
# cp uwsgi /usr/sbin/

运行 uWSGI

通过 trac-admin 工具生成 wsgi发布脚本
```
# trac-admin /data/app/tracs/trac deploy /data/app/tracs/
```
- 生成 /data/app/tracs/cgi-bin 目录
- 其中的 trac.wsgi 就是发布脚本

生成所有依赖目录信息:

# python

>>> import sys

...
pythonpath=/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg

pythonpath=/usr/lib/python2.6/site-packages/epydoc-3.0.1-py2.6.egg
...

编写 uWSGI 配置文件 vi /data/app/tracs/cgi-bin/uwsgi.ini:

[uwsgi]
uid=www
gid=www
socket=/usr/local/nginx/tmp/uwsgi_temp/trac.sock
processes=5
pidfile=/usr/local/nginx/run/trac.uwsgi.pid

pythonpath=/usr/lib/python2.6/site-packages/pytz-2010o-py2.6.egg

pythonpath=/usr/lib/python2.6/site-packages/psycopg2-2.3.0-py2.6-linux-i686.egg
pythonpath=/usr/lib/python2.6/site-packages/chardet-1.0.1-py2.6.egg
pythonpath=/usr/lib/python2.6/site-packages/supervisor-3.0a9-py2.6.egg
pythonpath=/usr/lib/python2.6/site-packages/meld3-0.6.7-py2.6.egg
pythonpath=/usr/lib/python26.zip
pythonpath=/usr/lib/python2.6
pythonpath=/usr/lib/python2.6/plat-linux2
pythonpath=/usr/lib/python2.6/lib-tk
pythonpath=/usr/lib/python2.6/lib-old
pythonpath=/usr/lib/python2.6/lib-dynload
pythonpath=/usr/lib/python2.6/site-packages

注意! 所有 pythonpath= 使用前述Py 交互环境的输出,以免Python 安装时的目录混乱,引发uWSGI 运行失败!

运行 uWSGI 守护:

# /usr/sbin/uwsgi --ini /data/app/tracs/cgi-bin/uwsgi.ini -d /usr/local/nginx/log/uwsgi.log

可以直接观察运行日志来确认是否正常:

# tail -f /usr/local/nginx/log/uwsgi.log
added /usr/lib/python2.6/site-packages to pythonpath.
initializing hooks...done.
application 0 () ready
setting default application to 0
spawned uWSGI master process (pid: 18956)
spawned uWSGI worker 1 (pid: 18957)

spawned uWSGI worker 3 (pid: 18959)
spawned uWSGI worker 4 (pid: 18960)
spawned uWSGI worker 5 (pid: 18961)
...

用Nginx 发布

配置/usr/local/nginx/conf/nginx.conf

     server {
        listen       80;
...
        location /trac {
            include     uwsgi_params;
            uwsgi_pass  unix:///usr/local/nginx/tmp/uwsgi_temp/trac.sock;
            # 确保以 http://foo.urs.org/trac 形式发布正常
            uwsgi_param SCRIPT_NAME /trac;  
            uwsgi_modifier1 30;
        }
...

测试配置:

# /usr/local/nginx/sbin/nginx -t
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful

发布KTRAC:

# kill -HUP `cat /usr/local/nginx/run/nginx.pid`

Supervisor: A Process Control System — supervisor v3.0a9 documentation

使用 Supervisor 可以统一管理所有 WSGI/FCGI/SCGI 动态应用的进程!
