Build a Python + Nginx + Tornado + Mysql environment using Centos

The combination of PythonTornado is gaining more and more attention. Like Nginx, Tornado uses epoll for process scheduling. The non-blocking call method easily solves the problem of high concurrency. In addition, Python is an artifact for lightweight and multi-concurrency program development. Therefore, this group looks pretty good. Next I will introduce

Therefore, this group looks pretty good.
Next I will introduce how to quickly build a running environment for UNIX (LINUX and MAC are configured in the same way:
1. Install 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. Install the Python package management tool setuptools, pip, and packaging tool 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. Install Readline

sudo pip install readline

4. Install Mysql

# Install cmake wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gztar Xvfz cmake-2.8.8.tar.gzcd./configuremakesudo make install # install 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-keys = 1-DSYSCONFDIR =/etc-DEXTRA_CHARSETS = all-DDEFAULT_CHARSET = utf8-DDEFAULT_COLLATION = utf8_unicode_ci-DWITH_DEBUG = 0 makesudo make install # download and install mysql-python 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 # modify site. path of mysql_config in py (/bin/mysql_config under mysql installation path), site. pymysql_config =/usr/local/mysql/bin/mysql_config # compile and install python setup. py buildsudo python setup. py install # Add the lib under the mysql installation path to the environment variable LD_LIBRARY_PATH export LD_LIBRARY_PATH =/usr/local/mysql/lib/: $ LD_LIBRARY_PATH

5. install some common Python modules and tornado

pip install tornadopip install torndb pip install requestspip install markdown

6. Configure 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. Install 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. Configure nginx and edit the/usr/local/nginx/conf/nginx. conf file.

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. Create a project

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. Run this project
# Start the project nohup python demo. py & # restart Nginx/usr/local/nginx/sbin/nginx-s reload

Enter http: // 127.0.0.1 in the browser to view the page output hello word!
