nginx uwsgi 部署集群方案

upstream myapp {
    server xx.xx.xx.xx:xxxx;
    server xx.xx.xx.xx:xxxx;
}

server {
    listen 80;
    listen 443 ssl;
    server_name xxx.xxx.xxx;

    ssl_stapling on;
    ssl_stapling_verify on;

    ssl_certificate /data/www/https/fullchain.crt;
    ssl_certificate_key /data/www/https/private.pem;

    ssl_session_timeout 5m;

    #请按照以下协议配置
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    #请按照以下套件配置，配置加密套件，写法遵循 openssl 标准。
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
    ssl_prefer_server_ciphers on;

    client_max_body_size 100m;

    location / {
        include uwsgi_params;
        proxy_pass http://myapp;
    }
}

upstream配置说明

upstream myapp1 {
        server srv1.example.com weight=3;
        server srv2.example.com;
        server srv3.example.com down;
        server srv4.example.com backup;
}
 
server {
        location / {
            proxy_pass http://myapp1;
        }
}

在这个配置中，srv1.example.com被赋予了3倍的权重，srv3.example.com被标记为down，意味着它当前不可用，srv4.example.com被标记为backup，意味着它只在所有其他服务器都宕机时才会被使用。
