Nginx + gunicorn + Flask部署

安装gunicorn

pip install gunicorn

查看命令选项

guniorn -h

调试执行命令

gunicorn -w 4 -b 192.168.31.113:5000 --access-logfile ./logs/log api:app

运维终端执行命令

# cd 到目录
gunicorn -w 4 -b 192.168.31.113:5000 -D --access-logfile ./logs/log api:app

gunicorn 查看后台进程

ps aux | grep gunicorn

杀死gunicorn进程

# 延迟时间较长，耐心等待
kill -9 28075

Nginx配置，在http中找到以下配置信息，upstream配置自带的参数，表示上游信息

    # 多服务配置 代码在http里面，server 外面
    upstream flask {
        server 192.168.199.208:5000;
        server 192.168.199.208:5001;
    }

    server {
        listen       8000;  # 端口不能用80和8080，已经被nginx占用，除非更改默认
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://flask; #收到的请求进行转发
            proxy_set_header Host $host; 
            proxy_set_header X-real-IP $remote_addr;
            
            root   html;
            index  index.html index.htm;
        }

brew 操作nginx命令：启动，重启，关闭

# 启动
brew services start nginx
# 重启
brew services restart nginx
# 关闭
sudo brew services stop nginx

nginx 配置文件 测试

# 测试配置文件
nginx -t

# 出现一下代码则表示测试通过
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful

查看端口是否被占用

sudo lsof -i:8080
