1. 首先弄懂下面几个东西的含义：

wsgi

uwsgi

gunicorn

supervisor

nginx

2.web之环境搭建

1) 创建虚拟环境：

virtualenv shan_env

source shan_env/bin/activate

2) 安装python 相关：

pip install -U bottle

pip install gevent

pip install gunicorn

3) index.py

from bottle import Bottle, run

app = Bottle()

@app.route('/')

@app.route('/hello')

def hello():

return "hello world"

@app.route('/login')

def login():

return "hello login"

#run(app, host='0.0.0.0', port=5003, debug=True)

4) 配置gunicorn：

# gunicorn.conf

# 并行工作进程数

workers = 4

# 指定每个工作者的线程数

threads = 2

# 监听内网端口5000

bind = '0.0.0.0:5003'

# 设置守护进程,将进程交给supervisor管理

daemon = 'false'

# 工作模式协程

worker_class = 'gevent'

# 设置最大并发量

worker_connections = 2000

# 设置进程文件目录

pidfile = '/var/run/gunicorn.pid'

# 设置访问日志和错误信息日志路径

accesslog = '/var/log/gunicorn_acess.log'

errorlog = '/var/log/gunicorn_error.log'

# 设置日志记录水平

loglevel = 'warning'

5) 通过gunicron启动web：

/home/user.dan/www/project_shan/shan_env/bin/gunicorn -c gunicorn.conf index:app

6)nginx 配置nginx.conf：

server {

listen  80;

root /home/user.dan/www/project_shan;

server_name shan.com;

access_log /home/user.dan/logs/access.log;

error_log /home/user.dan/logs/error.log;

location / {

proxy_pass http://127.0.0.1:5003;

proxy_set_header Host $host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

7)supervisor使用进程管理：

/etc/supervisor/conf.d/shan.ini

[program:shan]

command=/home/user.dan/www/project_shan/shan_env/bin/gunicorn -c gunicorn.conf index:app

directory=/home/user.dan/www/project_shan

autostart=true

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

/usr/bin/python2.7 ./supervisord

supervisorctl status

supervisorctl stop shan

supervisorctl update

#更新新的配置到supervisord

supervisorctl update

#重新启动配置中的所有程序

supervisorctl reload

#启动某个进程(program_name=你配置中写的程序名称)

supervisorctl start program_name
