环境

1、Ubuntu 服务器

2、python3.7.5

安装

1、python3.7.5

安装的话还是比较简单,流程大致是
./configure ->make && make install ->创建python软连接  pip软连接

安装起来倒是简单,安装完成运行才会遇到各种各样的问题,缺少插件啥的。

1.1、下载包  python3.7.5

1.2、问题

  a、No module named '_ctypes'

  sudo apt-get install libffi-dev 需不需要重新安装看ok不

  b、No module named _ssl

  安装之前修改下安装包里面的modules里面的setup.dist文件的内容

  ex:  /usr/web/tornadoTest/package/Python-3.7.5/Modules/Setup.dist   我的安装目录

  大约 206行左右,去掉注释即可

  

  然后再重新安装,等pip这些可以用起来了在开始下一步。

2、安装所需的package

需要的包有mysqldb  tornado  torndb,看你用的是pymysql还是mysqldb

 2.1  普通安装  pip install

 2.2 mysqldb 安装

  安装mysqldb 之前需要配置mysql_config

  sudo apt-get install libmysqlclient-dev

  sudo apt-get install python-dev

  

  然后安装。

3、启动错误

3.1 torndb的错误

  if MySQLdb is not None:

  # Fix the access conversions to properly recognize unicode/binary

  FIELD_TYPE = MySQLdb.constants.FIELD_TYPE

  FLAG = MySQLdb.constants.FLAG

  CONVERSIONS = copy.copy(MySQLdb.converters.conversions)

  field_types = [FIELD_TYPE.BLOB, FIELD_TYPE.STRING, FIELD_TYPE.VAR_STRING]

  if 'VARCHAR' in vars(FIELD_TYPE):

  field_types.append(FIELD_TYPE.VARCHAR)

  #for field_type in field_types:

  # CONVERSIONS[field_type] = [(FLAG.BINARY, str)] + CONVERSIONS[field_type]

  注释掉这个

 3.2 然后启动成功查询数据时可能还会原道这种错误。

4、nginx 配置

 4.1、tornado服务可以运行

  python server.py --port 8888

  nohup python server.py 登出也不会停止。

 4.2、配置

  

  default.conf

5、supervisor 配置

5.1、安装supervisor

  sudo apt-get install supervisor

  创建配置文件
  echo_supervisord_conf > /etc/supervisord.conf

  

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment
; variables can be expanded using this syntax: "%(ENV_HOME)s".
; - Quotes around values are not supported, except in the case of
; the environment= options as shown below.
; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
;
; Warning:
; Paths throughout this example file use /tmp because it is available on most
; systems. You will likely need to change these to locations more appropriate
; for your system. Some systems periodically delete older files in /tmp.

 再建一个配置文件

tornado.conf

[group:tornadoes]
programs=tornado-8888 [program:tornado-8888]
command=/usr/bin/python /usr/web/tornadoTest/server.py --port=8888 ##python tornado启动py
directory=/usr/web/tornadoTest
user=root
autorestart=true
redirect_stderr=true
stdout_logfile=/usr/web/tornadoTest/logs
loglevel=info

5.2 启动

  启动 supervisord -c /etc/supervisord.conf  指定配置文件

  supervisorctl shutdown  关闭supervisor

  

  至此。

附上api的代码

  server.py

#!/usr/bin/env python
# -*- coding:utf-8 -*- import tornado.ioloop
