linux 部署flask项目

news2024/9/23 21:22:07

linux python环境安装: https://blog.csdn.net/weixin_41934979/article/details/140528410

1.创建虚拟环境

python3.12 -m venv .venv

2.激活环境

 . .venv/bin/activate

3.安装依赖包(pip3.12 install -r requirements.txt)

pip3.12 install -r requirements.txt

4.测试启动项目

python3.12 app.py

5.在虚拟环境中安装gunicorn

pip install gunicorn

6.安装配置Supervisor

6.1安装Supervisor

CentOS

首先，安装 EPEL 扩展源（如果尚未安装）：

sudo yum install epel-release

然后，使用 yum 命令安装 Supervisor：

sudo yum install supervisor

Ubuntu

sudo apt install supervisor

查看版本，确认supervisor是否成功安装

supervisord --version

6.2配置supervisor

查看supervisor的配置

注意不同版本的Linux系统，不同版本supervisor，配置文件路径可能不同

CentOS

cat /etc/supervisord.conf

主要配置代码如下(主要看[include]下的文件路径):

; 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]
files = supervisord.d/*.ini

Ubuntu

cat /etc/supervisor/supervisord.conf

; 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]
files = /etc/supervisor/conf.d/*.conf

创建.ini配置文件或者.conf配置文件(具体要看[include]下面路径是*.ini,还是*.conf)，

文件要放进 [include]下的文件路径里

这里以Ubuntu为例

再次提醒.conf配置文件，文件要放进：[include]下的文件路径里，

放进/etc/supervisor/conf.d路径里

创建文件flaskapi.conf配置文件

 vi /etc/supervisor/conf.d/flaskapi.conf

内容如下：

[program:flaskapi] ; :右边是项目名称
command=/bin/bash -c ". .venv/bin/activate&&nohup python -m gunicorn -D -w 4 -b 0.0.0.0:8011 -t 120 app:app --access-logfile access.log --error-logfile error.log" ; 启动虚拟环境下的gunicorn，这里建议使用绝对路径
directory=/usr/projects/flask-api ; 程序的启动目录，这里是Flask网站根目录
user=root ; 用户名
autostart=true ; 在 supervisord 启动的时候也自动启动
autorestart=true ; 程序异常退出后自动重启
stopasgroup=true ; 它表示当该进程停止时，与该进程属于同一组的所有相关进程也会同时停止
killasgroup=true ; "杀死"整个组的进程
loglevel=info ; 日志级别设置为“信息”级别
