Supervisor托管Flask项目，supervisor托管flask
1 环境需求
- Ubuntu
- pip
- virtualenv
- Flask
- Gunicorn
2 环境部署
2.1Ubuntu环境部署
pip部署
安装
sudo apt-get install python-pip
sudo apt-get install pyhton3-pip
查看版本
pip -V
pip3 -V
2.2 viurtualenv部署
安装
sudo apt-get install virtualenv
新建指定py版本虚拟环境
virtual -p /usr/bin/python2 py2env
virtual -p /usr/bin/python3 py3env
激活虚拟环境
cd 新建虚拟环境的路径
source py2env/bin/activate
source py3env/bin/activate
停用虚拟环境
deactivate
修改虚拟环境用户
# 进入虚拟环境文件夹
cd py2env
cd py3env
# 修改该文件夹的用户为当前用户
# 这样就可以直接pip安装文件
# 如果用sudo是全局安装，不是在虚拟环境安装
sudo chown xindq -R *
sudo chown xindq -R *
2.3 Flask部署
安装
(py2env)pip install flask
(py2env)pip install flask
框架
from flask import Flask
app = Flask(__name__)
@app.route('/api', methods=[GET,POST])
def api():
return 'Api test！'
if __name__ == '__main__':
app.run(host='0.0.0.0', port=8080, debug=True)
运行
(py2env)python app.py
(py3env)python app.py
访问
http://127.0.0.1:8080/api
2.4 gunicorn部署
安装
(py2env)pip install gunicorn
(py3env)pip install gunicorn
配置
gunicorn -w 4 -b [inetIP]:[port] [fileName]:[serverName]
w:gunicorn开启的进程数；
b:绑定服务地址及端口；
inetIP：内网IP；
port:绑定运行端口；
fileName:需要监控的py文件(包含运行的服务)；
serverName：服务的名称；
查看内网地址
ifconfig
例子
#输入，即可运行app服务
gunicorn -w 4 -b 127.0.0.1:8080 chatbot:app
源码chatbot.py
from flask imprort Flask
app = Falsk(__name__)
@app.route('/connect', methods=[GET])
return 'Service is runing...'
if __name__ == '__main__':
app.run(host='0.0.0.0', port=8080, debug=True)
2.5 supervisor部署
2.5.1 安装
#python2环境
sudo apt-get install supervisor
2.5.2 配置supervisord.conf
- /etc/supervisor/supervisord.conf
; supervisor config file
[unix_http_server]
file=/var/run/supervisor.sock ; (the path to the socket file)
chmod=0700 ; sockef file mode (default 0700)
[supervisord]
nodaemon=true
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)
; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///var/run//supervisor.sock ; use a unix:// URL for a unix socket
; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
[include]
;单个程序
files = /etc/supervisor/conf.d/chatbot.conf
;多个程序，同时写入conf.d文件夹中
;如有chatbot和face_recognition两个程序
;程序设计如下
;chatbot.conf和face_recognition.conf
files = /etc/supervisor/conf.d/*.conf
;注意，python中的文件后缀，可以更改
;经验：A用py2，B用py3
;使用的conf不兼容
;有后缀隔离自己配置：如*.ini, *.txt
;supervisor控制台
[inet_http_server]
port=*:8080
username=xindaqi
password=123456
2.5.３ 配置程序文件chatbot.conf
- /etc/supervisor/conf.d/chatbot.conf
[program:app]
#执行gunicorn命令
command=/sourcePath/py3envinstall/bin/gunicorn -w 4 -b 127.0.0.1:8080 chatbot:app
directory=/sourcePath
#必须添加用户
user=xindq
#自动启动
autostart=true
#自动重启
autorestart=true
#日志
stdout_logfile=/sourcePath/logs/gunicorn_supervisor.log
2.5.4 supervisor使用
#进入/etc/supervisor目录
#启动服务
sudo supervisord -c supervisord.conf
#查看supervisor状态
sudo supervisordctl -c supervisord.conf status
#重新载入
sudo supervisorctl -c supervisord.conf reload
#开启服务
supervisorctl -c supervisord.conf start
#关闭服务
supervisorctl -c supervisord.conf stop
2.5.6 supervisor使用
#重新载入
sudo supervisorctl reload
#启动
sudo service supervisor start
#重启
sudo service supervisor restart
#查看supervisor当前状态
sudo supervisorctl
#启动app
start app
#停用app
stop app
3 测试
#启动supervisor
sudo supervisord -c supervisord.conf
#查看状态
sudo supervisorctl
#启动app
start app
#启动Postman测试
# 查看supervisor状态
0.0.0.0:8080
- supervisor登录
- supervisor监控界面
4 安装supervisor问题总结
- 问题1
$ sudo supervisorctl reload
$ sudo supervisord -c supervisord.conf
error: <class 'socket.error'>, [Errno 111] Connection refused: file: /usr/lib/python2.7/socket.py line: 228
$ sudo supervisorctl
unix:///var/run/supervisor.sock no such file
$ sudo supervisorctl
unix:///var/run/supervisor.sock refused connection
解决方案
#修改xhchatbot.conf文件
[program:app]#app为服务的名称
user= xindq#服务器用户名称
- 问题2
app FATAL Exited too quickly (process log may have details)
app: ERROR (spawn error)
【原因】
未在虚拟环境下启动app。
【解决方案】
在虚拟环境下启动app。
source py3env/bin/activate
sudo supervisorctl
start app
