摘要：以為例系統初始化步驟初始化用戶豆瓣源，可以換成其他的源取消版本檢查，排除每次都報最新的具體配置文件后續說明添加開機自啟配置的情形，其實只要指

以ubuntu為例：

#!/bin/bash

#初始化用戶
sudo useradd -rm -s /bin/bash demo
sudo adduser demo sudo
sudo passwd demo

sudo apt-get install build-essential python-software-properties software-properties-common -y
sudo apt-get install vim nano -y
sudo apt-get install supervisor -y

sudo add-apt-repository ppa:nginx/stable 
sudo add-apt-repository -y ppa:rwky/redis
sudo apt-get update

sudo apt-get install nginx aria2 axel wget curl -y
sudo apt-get install  redis-server -y

sudo apt-get install build-essential libssl-dev libffi-dev python-dev python3-dev -y
sudo apt-get install python3-pip -y
sudo apt-get install  convmv libevent-dev libssl-dev libffi-dev libsasl2-dev libpq-dev  libxml2-dev libxslt1-dev libldap2-dev  -y

vim ~/.pip/pip.conf
#[global]
#index-url = https://pypi.douban.com/simple #豆瓣源，可以換成其他的源
#disable-pip-version-check = true          #取消pip版本檢查，排除每次都報最新的pip
#timeout = 120

sudo pip3 install virtualenv
mkdir venv && cd venv 
virtualenv mdwiki
source mdwiki/bin/activate

pip3 install gunicorn

#具體配置文件后續說明
sudo vim  mdwiki/gunicorn.conf.py
sudo vim /etc/supervisor/conf.d/default.conf
sudo vim /etc/nginx/conf.d/default.conf

#添加開機自啟
sudo vim /etc/rc.local
#/usr/bin/supervisord -c /etc/supervisor/supervisord.conf

sudo update-rc.d nginx disable

celery+virtualenv+supervisor的情形，其實只要指定celery程序為virtaulenv下面的那個即可，例如/home/xby/venv/mdwiki/bin/celery

如果在gunicorn下出現"ascii" codec can"t encode...報錯，那么請在supervisor加入environment如下

environment=LANG="en_US.utf8", LC_ALL="en_US.UTF-8", LC_LANG="en_US.UTF-8"
