Nginx 配置

2018-05-26

安装nginx

1	brew install nginx

配置nginx

配置文件: /usr/local/etc/nginx/nginx.conf

将 http 部分修改成下面的配置

http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;

  log_format    main  '$remote_addr - $remote_user [$time_local] "$request" '
  '$status $body_bytes_sent "$http_referer" '
  '"$http_user_agent" "$http_x_forwarded_for"';

  access_log    /var/log/nginx/access.log  main;    #日志文件存放位置

  sendfile      on;

  keepalive_timeout  65;

  gzip on;
  gzip_http_version  1.0;
  gzip_disable       "MSIE [1-6].";
  gzip_min_length    512;
  gzip_types         text/plain application/x-javascript text/css text/javascript application/javascript application/xml application/json;

  include servers/*.conf;
}

如果日志文件的路径不存在, 则需要先创建: sudo mkdir -p /var/log/nginx/

修改访问权限: sudo chmod -R a+rw /var/log/nginx/

如果出现没有权限访问access.log文件, 可手工创建, 并修改权限:

touch /var/log/nginx/access.log && sudo chmod a+rw /var/log/nginx/access.log

代理配置

配置文件: /usr/local/etc/nginx/proxy.conf

proxy.conf的内容如下:

proxy_redirect          off;
proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr;
client_max_body_size    10m;
client_body_buffer_size 128k;
proxy_connect_timeout   300;
proxy_send_timeout      300;
proxy_read_timeout      300;
proxy_buffer_size       4k;
proxy_buffers           4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

配置转发

配置文件: /usr/local/etc/nginx/servers/food.conf

注意:

请将配置文件中的 /root/workspace/project/src 修改为本地路径

#测试服务器

upstream sandbox {
  server sandbox.com:80;
}

#正式服务器

upstream deploy {
  server deploy.com;

server {
  listen 80;
  server_name  localhost 127.0.0.1; #可通过这二个地址访问

#日志文件的存放位置
  access_log    /var/log/nginx/food-access.log  main;
  error_log     /var/log/nginx/food-error.log;

  index index.html;

  location /api {
    proxy_pass              http://sandbox.com/api;
    # Host限定
    proxy_set_header        Host sandbox.com;
    include proxy.conf;
  }

  location /admin {
    proxy_pass              http://sandbox.com/admin;
    # Host限定
    proxy_set_header        Host sandbox.com;
    include proxy.conf;
  }

  location / {
    root        /root/workspace/project/src;  #将该地址指向正确的项目路径
    index       index.html index.htm;
  }

  location @badrequest {
    default_type "application/json; charset=utf-8";
    if ($http_x_locale ~* "^zh") {
      return 400 "{\"error\":{\"code\":96,\"message\":\"请求不正确\"}}";
    }
    return 400 "{\"error\":{\"code\":96,\"msg\":\"Bad request\"}}";

    }

  }

    if ($http_x_locale ~* "^zh") {

    }
    return 500 "{\"error\":{\"code\":98,\"message\":\"Unknown error, please retry later\"}}";
  }
  location @maintenance{
    default_type "application/json; charset=utf-8";
    if ($http_x_locale ~* "^zh") {
      return 503 "{\"error\":{\"code\":99,\"message\":\"很抱歉，服务器维护中，请稍后重试\"}}";
    }
    return 503 "{\"error\":{\"code\":99,\"message\":\"The server is under maintenance, please retry later\"}}";
  }
  error_page 400 = @badrequest;
  error_page 404 = @versiontooold;
  error_page 500 = @servererror;
  error_page 502 503 504 = @maintenance;
}
