本文介绍在Linux使用Python+Nginx+web2py+uWSGI搭建一个web服务器的过程。

Python 2.7.11

解压安装包 

 tar -zxvf Python-2.7.11.tgz    cd Python-2.7.11    yum install sqlite-devel    ./configure --enable-loadable-sqlite-extensions

会提示错误 

 Python build finished, but the necessary bits to build these modules were not found:    _ssl _tkinter bsddb185    bz2 dl imageop    sunaudiodev    To find the necessary bits, look in setup.py in detect_modules() for the module's name.

需要安装相应的依赖包 

 yum install openssl-devel
按照依赖包操作，具体可以参照这篇 文档

继续安装 

 make    make install    rm /usr/bin/python    ln -s /usr/local/bin/python2.7 /usr/bin/python

python

Python 2.7.11 (default, Feb 2 2016, 14:33:40)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2

安装Nginx

tar -zxvf nginx-1.8.0.tar.gz   tar -xzvf zlib-1.2.8.tar.gz  tar -zxvf pcre-8.37.tar.gz  groupadd nginx  useradd nginx  ./configure \  --prefix=/usr/local/nginx \  --user=nginx \  --group=nginx \  --with-pcre=/opt/web/pcre-8.37 \  --with-zlib=/opt/web/zlib-1.2.8 \  --with-http_addition_module \  --with-http_realip_module  make  make install    cd /usr/local/nginx  ./nginx

安装uWSGI

tar -zxvf uwsgi-latest.tar.gz  cd uwsgi-2.0.12  python uwsgiconfig.py --build  cp uwsgi /usr/sbin

配置uWSGI

创建配置文件 /etc/uwsgi/web2py.ini ，并在配置文件中输入以下内容。 

 [uwsgi]    socket = 127.0.0.1:9090    pythonpath = /var/www/html/web2py/    mount = /=wsgihandler:application    processes = 4    master = true    harakiri = 60    reload-mercy = 8    cpu-affinity = 1    stats = /tmp/%n.stats.socket    max-requests = 5000    limit-as = 1024    reload-on-as = 256    reload-on-rss = 192    cron = 0 0 -1 -1 -1 python /var/www/html/web2py/web2py.py -Q -S welcome -M -R scripts/sessions2trash.py -A -o    no-orphans = true    chmod-socket = 666

创建uWSGI开关命令。 

 '#!/bin/sh    '# Autor: Nilton OS -- www.linuxpro.com.br    '#    '#    '### BEGIN INIT INFO    '# Provides: uwsgi    '# Required-Start: $syslog $remote_fs    '# Should-Start: $time ypbind smtp    '# Required-Stop: $syslog $remote_fs    '# Should-Stop: ypbind smtp    '# Default-Start: 3 5    '# Default-Stop: 0 1 2 6    '### END INIT INFO

'# Source function library.. /etc/rc.d/init.d/functions

'# Check for missing binaries (stale symlinks should not happen)

UWSGI_BIN= which uwsgi

test -x \(UWSGI_BIN || { echo "\) UWSGI_BIN not installed";

if [ "$1" = "stop" ]; then exit 0;

else exit 5; fi; }

UWSGI_EMPEROR_MODE=true

UWSGI_VASSALS="/etc/uwsgi/"

UWSGI_OPTIONS="--enable-threads --logto /var/log/uwsgi/uwsgi.log"

lockfile=/var/lock/subsys/uwsgi

UWSGI_OPTIONS="$UWSGI_OPTIONS --autoload"

if [ "$UWSGI_EMPEROR_MODE" = "true" ] ; then

UWSGI_OPTIONS="$UWSGI_OPTIONS --emperor $UWSGI_VASSALS"

fi

case "$1" in

start)

echo -n "Starting uWSGI "

daemon $UWSGI_BIN $UWSGI_OPTIONS &

;;

stop)

echo -n "Shutting down uWSGI "

killproc $UWSGI_BIN

;;

restart)

$0 stop

$0 start

;;

status)

echo -n "Checking for service uWSGI "

status $UWSGI_BIN

;;

*)

echo "Usage: $0 {start|stop|status|restart}"

exit 1

;;

esac

exit 0

根据上面的开关命令，还需要增加一个uWSGI的日志文件。 

 mkdir -p /var/log/uwsgi    touch /var/log/uwsgi/uwsgi.log

web2py安装

所谓的安装只需要将web2py的包解压到指定目录就可以，从 官网 可以下载二进制包。 

mkdir /var/www/html  unzip web2py_src.zip  mv web2py/handlers/wsgihandler.py web2py/wsgihandler.py  chown -R nginx:nginx web2py  cd web2py  sudo -u nginx python -c "from gluon.main import save_password; save_password('password',443)"

配置NginX

增加一个server模块，监听80端口，将访问使用uWSGI转移到web2py。 

 server {     listen 80;     server_name YOUR_SERVER_FQDN;
    '#to enable correct use of response.static_version      location ~* /(\w+)/static(?:/_[\d]+\.[\d]+\.[\d]+)?/(.*)$ {          alias /var/www/html/web2py/applications/$1/static/$2;          expires max;      }      location / {          uwsgi_pass      127.0.0.1:9090;          uwsgi_pass      unix:///var/www/html/web2py/logs/web2py.socket;          include         /etc/nginx/uwsgi_params;      }

}

启动Nginx和uWSGI

注意：web2py本身不需要启动，只用被uWSGI被动调用即可。

/usr/local/nginx/sbin/nginx    /etc/init.d/uwsgi start

以上执行完后，在浏览器访问服务器的IP地址，若需要以下页面则说明部署成功。
