mkdir data 目录文件夹 cd data 进入data文件夹 mkdir nginx 创建安装nginx的文件夹 mkdir server 存放代码的文件夹 mkdir logs 存放日志的文件夹 mkdir backup 备份代码的文件夹 mkdir softs 软件存放的位置 mkdir virtual 虚拟环境的位置 mkdir scripts 脚本的运行位置 mkdir scp_codes 上传的代码
apt-get install python-virtualenv （ubuntu已经安装过，可省略） virtualenv -p /usr/bin/python3 api_server (采用他，安装在本文件夹,) mkvirtualenv api_server(不要用它，它会自己安装到其他地方) source api_server/bin/activate (在虚拟环境的active进入虚拟环境) 安装的软件会在虚拟环境下的bin目录下
解压 cd ~/data/softs/ tar xf pcre-8.39.tar.gz 配置 cd ~/data/softs/pcre-8.39 ./configure 编译 make 安装 sudo make install
解压 cd ~/data/softs/ tar xf nginx-1.10.2.tar.gz 配置 cd nginx-1.10.2/ ./configure --prefix=/root/data/nginx 安装在root/data下面的nginx文件夹 编译 make 安装 make install 查看进程 ps aux | grep nginx

pip install gunicorn 复制代码
from werkzeug.contrib.fixers import ProxyFix app.wsgi_app = ProxyFix(app.wsgi_app) 复制代码
例：
from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello World!' if __name__ == '__main__': from werkzeug.contrib.fixers import ProxyFix app.wsgi_app = ProxyFix(app.wsgi_app) app.run() 复制代码 最简单的方式为
gunicorn 入口文件名:app 复制代码
默认是监听127.0.0.1:8000
如果是要处理高并发则要开多个进程和修改监听端口的画
gunicorn -w 4 -b 127.0.0.1:8000 入口文件名:app 复制代码保存在supervisord 里面的etc/supervisord.d目录下添加一个logo.ini配置文件
vim /etc/supervisord.d/logo.ini
[program:logo_api_server] directory = /data/api-service #代码存放的地方 command = /usr/local/python3/bin/gunicorn -w 4 -b :5005 LogoSeverApi:app #-w的参数根据CPU的核数来定，不要超过CPU的核数 #process_name = %(process_num)s ; process_name expr (default %(program_name)s) #process_name = %(process_num)s #numprocs = 4 ; number of processes copies to start (def 1) numprocs_start = 1 autostart = true ; start at supervisord start (default: true) autorestart = unexpected ; whether/when to restart (default: unexpected) startsecs = 10 ; number of secs prog must stay running (def. 1) startretries = 3 ; max # of serial start failures (default 3) user = dev redirect_stderr = true stdout_logfile_maxbytes = 20MB stdout_logfile_backups = 20 stdout_logfile = /data/api-service/logs/supervisor.log
这样就可以启动4个进程同时处理HTTP请求，提高系统的使用效率及性能。 还可以把端口8000改为其他
而在实际应用中，应使用后台执行的方式启动服务
nohup 启动服务的命令 & 复制代码
即
nohup gunicorn -w 4 -b 127.0.0.1:8000 入口文件名:app & 复制代码
这时你可以在本机的浏览器上访问127.0.0.1:8000，浏览器上就会出现Hello World!
注意：如果是想通过外网访问的话就要把ip改为内网的ip
配置改为
server { listen 80; server_name example.org; # 这是HOST机器的外部域名，用地址也行 location / { proxy_pass http://127.0.0.1:8000; # 这里是指向 gunicorn host 的服务地址 proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } 复制代码 这样启动之后80端口就可以转发到8000端口了
nginx -t 复制代码
若出现一下内容，则表示配置成功
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful 复制代码
nginx -s reload 复制代码
在已经运行了Gunicorn的前提下，在浏览器访问127.0.0.1就会出现Hello World!了
输入命令
pstree -ap|grep gunicorn
