h3blog linux+python虚拟环境下flask使用gunicorn+nginx高并发部署

背景

总有人问我h3blog博客怎么部署，这里简单写下过程

1、下载源码

$ git clone https://gitee.com/pojoin/h3blog.git
$ cd h3blog
$ python -m venv venv  #创建python虚拟环境
$ source venv/bin/activate
$ 
$ pip install -r requirements.txt # 安装项目依赖，可能不全，根据提示自行安装即可

2、修改配置文件

$ vim .env

FLASK_CONFIG=production
DATABASE_URL=mysql+pymysql://root:123456@127.0.0.1/h3blog?charset=utf8

H3BLOG_UPLOAD_TYPE=qiniu
QINIU_CDN_URL=http://cdn.h3blog.com/
QINIU_BUCKET_NAME=h3blog
QINIU_ACCESS_KEY=Kio7HR9o7mUpSFdLjLwJvKxAaeTAgnXpJ4hT-h_J
QINIU_SECRET_KEY=eEHXUpudwApbuTRWQl0k1mbJZwO1Pv-iWx77Mltd

H3BLOG_DOMAIN=https://www.h3blog.com
BAIDU_PUSH_TOKEN=TagL7I7By8xm4Nm5

SITEMAP_URL_SCHEME=https

3、安装gunicorn

pip install gunicorn
pip install gevent

4、配置gunicoren开机自启

# vim /etc/systemd/system/gunicorn_h3blog.service

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=root
Group=www-data
WorkingDirectory=/data/h3blog
ExecStart=/data/h3blog/venv/bin/gunicorn -c /data/h3blog/gunicorn.py  wsgi:app

[Install]
WantedBy=multi-user.target

gunicorn.py内容如下：

import logging
import logging.handlers
from logging.handlers import WatchedFileHandler
import os
import multiprocessing

project_path = os.path.dirname(__file__)
print(project_path)

bind = f'unix:{project_path}/h3blog.sock' #绑定ip和端口号
# daemon = True  # 是否开启守护进程模式
backlog = 512   #监听队列
chdir = f'{project_path}'  #gunicorn要切换到的目的工作目录
timeout = 30  #超时
worker_class = 'gevent' #使用gevent模式，还可以使用sync 模式，默认的是sync模式
workers = multiprocessing.cpu_count() * 2 + 1    #进程数
threads = 2 #指定每个进程开启的线程数
loglevel = 'info' #日志级别，这个日志级别指的是错误日志的级别，而访问日志的级别无法设置
access_log_format = '%(t)s %(p)s %(h)s "%(r)s" %(s)s %(L)s %(b)s %(f)s" "%(a)s"'    #设置gunicorn访问日志格式，错误日志无法设置

"""
其每个选项的含义如下：
h          remote address
l          '-'
u          currently '-', may be user name in future releases
t          date of the request
r          status line (e.g. ``GET / HTTP/1.1``)
s          status
b          response length or '-'
f          referer
a          user agent
T          request time in seconds
D          request time in microseconds
L          request time in decimal seconds
p          process ID
"""
capture_output = True # 是否捕获输出
accesslog = f"{project_path}/logs/gunicorn_access.log"      #访问日志文件
errorlog = f"{project_path}/logs/gunicorn_error.log"        #错误日志文件

开机自启

# systemctl enable gunicorn_h3blog.service

启动gunicorn

# systemctl start gunicorn_h3blog.service

5、安装nginx

apt install nginx

6、配置nginx

# vim /etc/nginx/sites-available/h3blog.com

    listen 80;
    server_name www.h3blog.com h3blog.com;

    }

        }

    location / {
        include proxy_params;
        proxy_pass http://unix:/data/h3blog/h3blog.sock;
    }

    #return 301 https://$server_name$request_uri;
}
