ubuntu初始化python3+postgresql+uwsgi+nginx+django

一. postgresql 数据库

安装

apt-get update
apt-get install postgresql

进入psql客户端

sudo -u postgres psql
创建数据库,修改默认用户密码

CREATE DATABASE dbname;
ALTER USER postgres WITH PASSWORD '123456';
q

跨服务器复制数据库

参考:http://www.cnblogs.com/xiangnan/p/6687029.html

二. Python3 + virtualenv + uwsgi + django 开发环境

安装pip

apt-get install build-essential python-dev python-pip python3-dev python3-pip libpq-dev

安装 virtualenv + uwsgi

pip install virtualenv
pip3 install uwsgi

参考:http://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

建立环境

假设工程目录~/venv/app

virtualenv -p python3 venv
cd venv && source bin/activate 
pip install django==1.9 jinja2 xlrd pillow pypinyin psycopg2
cd app
python manage.py collectstatic
python manage.py makemigrations
python manage.py migrate

最后退出virtualenv
deactivate

三. 其他

uwsgi守护进程

这样在使用诸如uwsgi uwsgi.ini的命令时,uwsgi进程将在后天进行.不占用当前shell.
daemonize = /some-path/access.log

uwsgi新开线程问题

需要 enable-threads = true
参考:http://stackoverflow.com/questions/15308718/how-can-i-use-uwsgi-web-py-to-run-background-function

uwsgi配置文件示例

[uwsgi]
uid = root
gid = root
chmod-socket = 666
chown-socket = root:root
#socket       = 127.0.0.1:3000
#below in nginx: uwsgi_pass unix:///path-to-socket/proj.sock;
socket       = /path-to-socket/proj.sock 

chdir           = /path-to-project/app
module          = proj.wsgi
home            = /path-to-project
chmod-socket    = 666
env             = DJANGO_SETTINGS_MODULE=proj.settings
master          = true
processes       = 1
vacuum          = true
pidfile         = /tmp/app
daemonize       = /path-to-project/app/access.log
# uwsgi --reload /tmp/app
