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  http://www.linuxidc.com/Linux/2016-06/132691.htm

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。
