在Linux上使用web2py_uwsgi_nginx搭建web服務器

本文介紹在Linux使用Python+Nginx+web2py+uWSGI搭建一個web服務器的過程。

Python 2.7.11

解壓安裝包

 tar -zxvf Python-2.7.11.tgz

cd Python-2.7.11
yum install sqlite-devel
./configure --enable-loadable-sqlite-extensions</pre> 
 
會提示錯誤 

 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.</pre> 
 
需要安裝相應的依賴包 

 yum install openssl-devel
 按照依賴包操作，具體可以參照這篇 
 文檔 
 
繼續安裝 

 make

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

安裝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</pre> 
 
安裝uWSGI

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

 創建配置文件 /etc/uwsgi/web2py.ini ，并在配置文件中輸入以下內容。 
 [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</pre> 
 
創建uWSGI開關命令。 

 '#!/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</pre> 
 
'# 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

 
根據上面的開關命令，還需要增加一個uWSGI的日志文件。 
 mkdir -p /var/log/uwsgi

touch /var/log/uwsgi/uwsgi.log</pre> 
 
web2py安裝

 所謂的安裝只需要將web2py的包解壓到指定目錄就可以，從 官網 可以下載二進制包。 
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

增加一個server模塊，監聽80端口，將訪問使用uWSGI轉移到web2py。 
 server {

listen 80;
server_name YOUR_SERVER_FQDN;</pre> 
 
    '#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;
    }
 
 
} 

啟動Nginx和uWSGI
注意：web2py本身不需要啟動，只用被uWSGI被動調用即可。
/usr/local/nginx/sbin/nginx

/etc/init.d/uwsgi start</pre> 
 
以上執行完后，在瀏覽器訪問服務器的IP地址，若需要以下頁面則說明部署成功。
