nginx+uwsgi+flask配置记录

nginx部分： nginx使用nginx官方yum源 详情：http://nginx.org/en/download.html nginx的配置文件： server { listen

nginx部分：

nginx的配置文件：

server {    listen       80;    server_name  www.iday.me;    access_log  /var/log/nginx/iday.me.access.log  main;    error_log  /var/log/nginx/iday.me.error.log ;    location / {	   include uwsgi_params;           uwsgi_pass  unix:/dev/shm/iday.me;    }	location =/favicon.ico {      alias /www/iday.me/static/img/favicon.ico;       }     location /static {                alias /www/iday.me/static ;        }      }

uwsgi部分：

uwsgi通过pypi来来装：

pip install uwsgi

配置uwsgi有些麻烦,把uwsgi源码里的用于cenots的init.d script文件提取出来，稍作修改：

#!/bin/bash# uwsgi - Use uwsgi to run python and wsgi web apps.## chkconfig: - 85 15# description: Use uwsgi to run python and wsgi web apps.# processname: uwsgi# author: Roman Vasilyev# Source function library.. /etc/rc.d/init.d/functionsPATH=/opt/uwsgi:/sbin:/bin:/usr/sbin:/usr/binprog=/usr/local/bin/uwsgiOWNER=nginxNAME=uwsgiDESC=uwsgiDAEMON_OPTS="--emperor '/etc/uwsgi/*.ini'  --listen 1024  -d /var/log/uwsgi/$NAME.log --uid $OWNER -M --pidfile /var/run/$NAME.pid"[ -f /etc/sysconfig/uwsgi ] && . /etc/sysconfig/uwsgilockfile=/var/lock/subsys/uwsgistart () {  echo -n "Starting $DESC: "  daemon $prog $DAEMON_OPTS  retval=$?  echo  [ $retval -eq 0 ] && touch $lockfile  return $retval}stop () {  echo -n "Stopping $DESC: "  killproc $prog  retval=$?  echo  [ $retval -eq 0 ] && rm -f $lockfile  return $retval}reload () {  echo "Reloading $NAME"   killproc $prog -HUP  RETVAL=$?  echo}force-reload () {  echo "Reloading $NAME"   killproc $prog -TERM  RETVAL=$?  echo}restart () {    stop    start}rh_status () {  status $prog}rh_status_q() {  rh_status >/dev/null 2>&1}case "$1" in  start)    rh_status_q && exit 0    $1    ;;  stop)    rh_status_q || exit 0    $1    ;;  restart|force-reload)    $1    ;;  reload)    rh_status_q || exit 7    $1    ;;  status)    rh_status    ;;  *)      echo "Usage: $0 {start|stop|restart|reload|force-reload|status}" >&2    exit 2    ;;  esac  exit 0

然后用chkconfig 把uwsgi加入服务。这里我使用--emperor '/etc/uwsgi/*.ini' 参数即用 emperor模式来运行虚拟主机

配置uwsgi最麻烦的是虚拟主机的配置，uwsgi有virtualHosting模式，但是该模式只适合你有少量网站，而且它以一种相当复杂的方式运行，并且很不安全。uwsgi建议使用emperor模式替代virtualhosting模式。

接下来只要把虚拟主机的配置文件放入/etc/uwsgi/目录下就可以了，附上一个配置文件：iday.me.ini

[uwsgi]mastermax-requests =10000processes = 2 pythonpath =/www/%nmodule =maincallable=appenable-threadssocket = /dev/shm/%nuid = nginxpost-buffering=4096logto=/var/log/uwsgi/%n.logpidfile=/var/run/uwsgi/%n.piddisable-logginglisten=10240ignore-sigpipe

 module=main 说的是flask项目的入口文件，main.py文件：

# -*- coding: utf-8 -*-import sysfrom models import *from views import *from app import appreload(sys)sys.setdefaultencoding('utf-8')if __name__ == '__main__':    app.run(host='0.0.0.0',port=81)

最后讲下面的uwsgi文件放入logrotate.d以便处理打包uwsgi产生的日志:

"/var/log/uwsgi/*.log" {  copytruncate  daily  rotate 5  compress  delaycompress  missingok  notifempty}
