我的nginx配置

先说一下我的项目的背景，

首先我采用的docker，一台服务器，采用docker-compose编排工具，我计划的是api一个docker(取名-lot-webapi)，前端静态页面一个docker(取名：lot-front)，后端静态页面一个docker(取名：lot-admin)，一个docker的nginx做分流（取名： lot-nginx）

1、首先是分流的docker-nginx

user  nginx;            #运行用户
worker_processes  1;        #启动进程,通常设置成和cpu的数量相等

#全局错误日志及PID文件
#error_log  /usr/local/nginx/logs/error.log;
#error_log  /usr/local/nginx/logs/error.log  notice;
#error_log  /usr/local/nginx/logs/error.log  info;
#pid        /usr/local/nginx/logs/nginx.pid;

# 工作模式及连接数上线
events 
{
    use epoll;            #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能

    worker_connections  1024;    #单个后台worker process进程的最大并发链接数
}

#设定http服务器,利用它的反向代理功能提供负载均衡支持
http 
{
    include       mime.types;
    default_type  application/octet-stream;

    #设定请求缓冲
    server_names_hash_bucket_size  128;
    client_header_buffer_size   32K;
    large_client_header_buffers  4 32k;
    # client_max_body_size   8m;
    
    #sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
    #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
    sendfile        on;
    tcp_nopush     on;
    tcp_nodelay    on;

    #连接超时时间
    keepalive_timeout  65;

    #开启gzip压缩，降低传输流量
    gzip  on;
    gzip_min_length    1k;
    gzip_buffers    4 16k;
    gzip_http_version  1.1;
    gzip_comp_level  2;
    gzip_types  text/plain application/x-javascript text/css  application/xml;
    gzip_vary on;

    #添加tomcat列表，真实应用服务器都放在这
    upstream webapi 
    {
       #server tomcat地址:端口号 weight表示权值，权值越大，被分配的几率越大;
       #server 192.168.0.223:8080 weight=4 max_fails=2 fail_timeout=30s;
       #server 192.168.0.224:8080 weight=4 max_fails=2 fail_timeout=30s;
       server lot-webapi:8000 fail_timeout=1;
    }

    upstream webapp{
     server lot-front:80 fail_timeout=1;
    }

    upstream webadmin{
     server lot-admin:80 fail_timeout=1;
    }

    server 
    {
        listen       80;        #监听端口    
        server_name api.dodododo.club localhost 47.92.33.70;
    
        #默认请求设置
        location / {
            proxy_pass http://webapi;    #转向.netcore处理

            proxy_set_header Host $proxy_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Via "nginx";

#            add_header ‘Access-Control-Allow-Origin‘ $http_origin;
#            #add_header ‘Access-Control-Allow-Origin‘ *;
#            add_header ‘Access-Control-Allow-Credentials‘ ‘true‘;
#            add_header ‘Access-Control-Allow-Methods‘ ‘GET, POST, OPTIONS‘;
#            add_header ‘Access-Control-Allow-Headers‘ ‘DNT,Authorization,Accept,Origin,Keep-Alive,User-Agent,X-Mx-ReqToken,X-Data-Type,X-Auth-Token,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,tkn,platform‘;
#            add_header ‘Access-Control-Expose-Headers‘ ‘Content-Length,Content-Range‘;
#            if ($request_method = ‘OPTIONS‘) {
#                add_header ‘Access-Control-Max-Age‘ 1728000;
#                add_header ‘Content-Type‘ ‘text/plain; charset=utf-8‘;
#                add_header ‘Content-Length‘ 0;
#                return 204;
#            }
        }
    }

    server
    {
        listen     80;
        server_name lot.dodododo.club;
        location / {
        proxy_pass http://webapp;    #转向.netcore处理

            proxy_set_header Host $proxy_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Via "nginx";
        }
    }

     server
    {
        listen     80;
        server_name admin.dodododo.club;
        location / {
        proxy_pass http://webadmin;    #转向.netcore处理

            proxy_set_header Host $proxy_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Via "nginx";
        }
    }
}

简单说一下配置，其他都没什么说的，网上一说一大巴，主要说一下三个upstream吧，三个upstream对应了三个server，每个server我分别绑定了三个域名，根据域名的不同做到分流的目的（其实就分到了三个docker）

关于注释的部分，其实就是跨域的配置，这里其实还绕了不少弯路，因为其实我的webapi里面已经做了跨域的设置，Nginx不应该在做配置。但是我做了，倒是我的前端页面一直请求失败。去掉Nginx的配置（就是注释部分）就行了

前端和后端因为都是静态页面，用Nginx做服务器，所以配置基本差不多，就贴一个就是了

user  nginx;            #运行用户
worker_processes  1;        #启动进程,通常设置成和cpu的数量相等

#全局错误日志及PID文件
#error_log  /usr/local/nginx/logs/error.log;
#error_log  /usr/local/nginx/logs/error.log  notice;
#error_log  /usr/local/nginx/logs/error.log  info;
#pid        /usr/local/nginx/logs/nginx.pid;

# 工作模式及连接数上线
events 
{
    use epoll;            #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
    worker_connections  1024;    #单个后台worker process进程的最大并发链接数
}

#设定http服务器,利用它的反向代理功能提供负载均衡支持
http 
{
    include       mime.types;
    default_type  application/octet-stream;

    #设定请求缓冲
    server_names_hash_bucket_size  128;
    client_header_buffer_size   32K;
    large_client_header_buffers  4 32k;
    # client_max_body_size   8m;
    
    #sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
    #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
    sendfile        on;
    tcp_nopush     on;
    tcp_nodelay    on;

    #连接超时时间
    keepalive_timeout  65;

    #开启gzip压缩，降低传输流量
    gzip  on;
    gzip_min_length    1k;
    gzip_buffers    4 16k;
    gzip_http_version  1.1;
    gzip_comp_level  2;
    gzip_types  text/plain application/x-javascript text/css  application/xml;
    gzip_vary on;

    server 
    {
        listen       80;        #监听端口
        server_name admin.dodododo.club;
        #默认请求设置
        location / {
            root /home/app;
            index index.html;
        }
    }
}
