python+tornado的组合正在得到越来越多人的关注。tornado和nginx一样采用epoll的方式进行进程的调度。非阻塞的的调用方式轻易就解决了大并发的问题，再加上python是开发轻量级、多并发程序的神器。所以，这个组给看上去相当不错。
下面我将介绍在unix（linux、mac下的配置方法其本一致）下如何快速搭建其运行环境：
1、安装python
wget http://www.python.org/ftp/python/2.7.5/python-2.7.5.tgz tar xvfz python-2.7.5.tgzcd python-2.7.5 ./configuremakesudo make install
2、安装python的包管理工具setuptools、pip和打包工具distribute
wget http://peak.telecommunity.com/dist/ez_setup.py python ez_setup.pywget http://python-distribute.org/distribute_setup.py python distribute_setup.pywget https://github.com/pypa/pip/raw/master/contrib/get-pip.py python get-pip.py
3、安装readline
sudo pip install readline
4、安装mysql
#安装cmake wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gztar xvfz cmake-2.8.8.tar.gzcd cmake-2.8.8./configuremakesudo make install #安装mysql wget http://cdn.mysql.com/downloads/mysql-5.5/mysql-5.5.29.tar.gztar xvfz mysql-5.5.29.tar.gzcd mysql-5.5.29cmake . -dcmake_install_prefix=/usr/local/mysql -dmysql_datadir=/usr/localmysql/data/ -dmysql_unix_addr=/usr/localmysql/data/mysqld.sock -dwith_innobase_storage_engine=1 -dsysconfdir=/etc -dextra_charsets=all -ddefault_charset=utf8 -ddefault_collation=utf8_unicode_ci -dwith_debug=0makesudo make install #下载安装mysql-python wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/mysql-python-1.2.3.tar.gztar xvfz mysql-python-1.2.3.tar.gzcd mysql-python-1.2.3 #修改site.py中mysql_config的路径（为mysql安装路径下的/bin/mysql_config）， site.pymysql_config = /usr/local/mysql/bin/mysql_config #更改完进行编译和安装 python setup.py buildsudo python setup.py install #将mysql安装路径下的lib加入到环境变量ld_library_path中 export ld_library_path=/usr/local/mysql/lib/:$ld_library_path
5、安装一些python的常用模块和tornado
pip install tornadopip install torndb pip install requestspip install markdown
6、配置mysql
groupadd mysql useradd -g mysql mysql chown mysql.mysql -r /service/mysql/ /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
7、安装nginx
wget http://nginx.org/download/nginx-0.8.33.tar.gz tar zxvf nginx-0.8.33.tar.gzcd nginx-0.8.33 ./configuremake make install
8、配置nginx，编辑/usr/local/nginx/conf/nginx.conf文件
user nobody;worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; upstream snail { server 127.0.0.1:8888; } sendfile on; #tcp_nopush on; keepalive_timeout 65; proxy_read_timeout 200; tcp_nopush on; tcp_nodelay on; gzip on; gzip_min_length 1000; gzip_proxied any; server { listen 80; server_name localhost; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location / { proxy_pass_header server; proxy_set_header host $http_host; # proxy_redirect false; proxy_set_header x-real-ip $remote_addr; proxy_set_header x-scheme $scheme; proxy_pass http://snail; } }}
9、创建一个项目
vi demo.pyimport tornado.ioloop import tornado.web class mainhandler(tornado.web.requesthandler): def get(self): self.write(hello, world)application = tornado.web.application([ (r/, mainhandler),]) if __name__ == __main__: application.listen(8888) tornado.ioloop.ioloop.instance().start()
10、运行这个项目
#启动项目 nohup python demo.py & #重启nginx /usr/local/nginx/sbin/nginx -s reload
在浏览器中输入http://127.0.0.1 看到页面输出hello word!
