Centos搭建Python+Nginx+Tornado+Mysql环境

来源：互联网发布：笨办法学python百度云编辑：程序博客网时间：2024/06/16 06:45

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!
