亲测可用centos7.4 + python3.6+ ngnix+ uwsgi flask环境安装配置

磕磕绊绊初学者踩过所有的坑69开了一年阿里云服务器

安装之前需要依赖依赖，yum安装就完事了，网上很多这种

nginx安装编译

习惯在这个目录下安装程序

cd /usr/local

wget http://nginx.org/download/nginx-1.6.2.tar.gz

 tar -zxvf nginx-1.6.2.tar.gz

cd /usr/local/nginx-1.6.2

./configure --prefix=/usr/local/nginx

make && make install

做个测试

/usr/local/nginx/sbin/nginx

ps -aux | grep nginx
查看是否启动

也可以访问浏览器访问 公网ip:80，看见欢迎ngnix
关闭

killall -9 nginx

修改配置文件能更便捷启动关闭

vim /etc/profile

文件末尾添加

	PATH=$PATH:/usr/local/nginx/sbin
	export PATH

更新配置文件

source /etc/profile

相当于ls软连接

	nginx # 启动
	nginx -s stop # 关闭
	nginx -s reload # 重启

修改nginx.conf

vim /usr/local/nginx/conf/nginx.conf

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            include uwsgi_params;   # *主要加这两行，复制完删除这两行#*注释
            uwsgi_pass 私网ip:8008; # *主要加这两行,其他能不动就不动吧
            root   html;
            index  index.html index.htm;
        }

uwsgi安装

pip install uwsgi  # 就行了

这是我项目目录
__pycache__目录没什么用
spider.py 是Crawl目录下的爬虫文件
manage.py 是flask主文件
log 日志
uwsgi.ini 新建uwsgi配置

    └── hub0415

创建uwsgi.ini文件

vim  /home/projectFlask/hub0415/uwsgi.ini

socket = 私网ip:8008
# python 启动程序文件
wsgi-file = /home/projectFlask/hub0415/manage.py
#  获取uwsgi统计信息的服务地址
stats = 私网ip:8080
# 在python文件中 app = Flask(__name__) 的app，否则500
callable = app
#  保存pid信息，方便停止服务和重启的时候用
pidfile = ./log/uwsgi.pid        
#  后台运行时记录uwsgi的运行日志
daemonize = ./log/uwsgi.log  
#更新py文件后重启wsgi
python-autoreload = 1

uwsgi软连接

ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi

uwsgi --ini /home/projectFlask/hub0415/uwsgi.ini

nginx -s reload

ps -aux | grep nginx
ps -aux | grep uwsgi
killall -9 uwsgi
killall -9 nginx

公网 39.100.20.111/lj/zf/bj/1

简易flask文件manage.py，就把pycharm基础helloworld模板改了一点点

from flask import Flask
from Crawl import spider

app = Flask(__name__)


@app.route('/lj/zf/bj/')
def lj_rent(p):
    '''
    area = xihu/    xiacheng/   jianggan/   gongshu/    shangcheng/     binjiang/       yuhang/     xiaoshan/
    fuyang/     linan/      qiantangxinqu/
    '''
    url = "https://hz.lianjia.com/zufang/binjiang/pg{}".format(p)
    response = spider.page_get(url=url)
    data = spider.page_parse(response)

    return data


if __name__ == '__main__':
    app.run(debug=True)
