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
##
# you should look at the following url's in order to grasp a solid understanding
# of nginx configuration files in order to fully unleash the power of nginx.
# http://wiki.nginx.org/pitfalls
# http://wiki.nginx.org/quickstart
# http://wiki.nginx.org/configuration
#
# generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. or just disable in sites-enabled.
#
# please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

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.
; notably, if the socket file defined in the [unix_http_server] section below
; is deleted, supervisorctl will be unable to connect to supervisord.

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。
