PHP-FPM和Nginx：502坏网关(PHP-FPM and Nginx: 502 Bad Gateway)

 组态 
 

     
 
  •  Ubuntu Server 11.10 64位 
    •  
 
  •  亚马逊AWS，Ec2，托管在云端 
    •  
 
  •  t1.micro实例 
    •  

 

 在我写任何其他内容之前，我想表示，我已经检查了nginx 502坏网关和Nginx + PHP-FPM 502坏网关线程，这不幸没有帮助我在这方面。 
 

 这个问题似乎很常见：nginx或php-fpm的配置错误可能会导致502 Bad Gateway错误，这是我无法摆脱的错误。 请注意， 即使我进入我的域根 ，也没有指定任何特定的目录。 
 

 我正在运行一个Amazon EC2网络服务器，启用端口9000，端口80打开等。 
 

 特别是这个问题，我该如何摆脱这个讨厌的错误？ 或者更好的是，如何让php5-fpm 实际工作 。 
 

 我已经尝试了甚么 
 

 大多数编辑配置文件，特别是php-fpm.conf和nginx.conf 。 
 

 一世。 PHP-fpm.conf 
 

 我添加了以下内容，这并没有太大帮助： 
 

;;;;;;;;;;;;;
; Fpm Start ;
;;;;;;;;;;;;;

;pm.start_servers = 20
;pm.min_spare_servers = 5
;pm.max_spare_servers = 35

 

 现在，我尝试包括我的配置文件： 
 

 include=/etc/php5/fpm/*.conf 
 

 这只是使我更进一步。 
 

 完全配置

 ii 。 nginx.conf 
 

 诚然，这个配置是我访问过的几个网站的一小部分，但是我可以告诉你，在这个502 Bad Gateway业务之前，服务器运行正常（没有PHP工作）。 
 

 这个问题主要在于一件事情是非常可怕的，非常错误的。 而现在，当我尝试service php5-fpm restart ，它挂起在我猜测是一个无限循环或者什么，我甚至不能CTRL - C出来。

Configuration
 

     
 
  • Ubuntu Server 11.10 64 bit
    •  
 
  • Amazon AWS, Ec2, hosted on the cloud
    •  
 
  • t1.micro instance
    •  

 

Before I write anything else, I'd like to state that I've checked both nginx 502 bad gateway and Nginx + PHP-FPM 502 Bad Gateway threads, which unfortunately haven't helped me in this regard.
 

The issue appears to be rather common: a misconfiguration of nginx or php-fpm can lead to a 502 Bad Gateway error, which is something that I haven't been able to get rid of. Note that this appears even when I go to my domain root, without specifying any particular directory. 
 

I'm running an Amazon EC2 webserver, with port 9000 enabled, port 80 open, etc.
 

The question in particular is, how can I get rid of this nasty error? Or, better yet, how can I get php5-fpm to actually work.
 

What I Have Attempted so Far
 

Mostly consistent editing of configuration files, notably php-fpm.conf and nginx.conf.
 

i. php-fpm.conf
 

I've added the following, which hasn't quite helped much:
 

;;;;;;;;;;;;;
; Fpm Start ;
;;;;;;;;;;;;;

;pm.start_servers = 20
;pm.min_spare_servers = 5
;pm.max_spare_servers = 35

 

Now, afterward I tried including my configuration files:
 

include=/etc/php5/fpm/*.conf
 

Which only screwed me even further.

ii. nginx.conf
 

In all honesty this configuration is a smattering of a few websites I've visited, but I can tell you that before this 502 Bad Gateway business, the server was running fine (without PHP working. Period.).
 

The issue primarily lies in the fact that something is terribly, terribly wrong. And now, when I try to do a service php5-fpm restart, it hangs in what I'm guessing is an infinite loop or something, which I can't even CTRL-C out of.

最满意答案

 如果您已经具有数值特征并且不需要其他转换，则可以使用VectorAssembler组合包含独立变量的列： 
 

from pyspark.ml.feature import VectorAssembler

assembler = VectorAssembler(
    inputCols=["your", "independent", "variables"],
    outputCol="features")

transformed = assembler.transform(parsedData)

 

 接下来你可以简单地映射： 
 

from pyspark.mllib.regression import LabeledPoint
from pyspark.sql.functions import col

(transformed.select(col("outcome_column").alias("label"), col("features"))
  .rdd
  .map(lambda row: LabeledPoint(row.label, row.features)))

 

 从Spark 2.0 ml和mllib API不再兼容，后者正在进行弃用和移除。 如果你仍然需要这个，你必须将ml.Vectors转换为mllib.Vectors 。 
 

from pyspark.mllib import linalg as mllib_linalg
from pyspark.ml import linalg as ml_linalg

def as_old(v):
    if isinstance(v, ml_linalg.SparseVector):
        return mllib_linalg.SparseVector(v.size, v.indices, v.values)
    if isinstance(v, ml_linalg.DenseVector):
        return mllib_linalg.DenseVector(v.values)
    raise ValueError("Unsupported type {0}".format(type(v)))

 

 和地图： 
 

lambda row: LabeledPoint(row.label, as_old(row.features)))


If you already have numerical features and which require no additional transformations you can use VectorAssembler to combine columns containing independent variables:
 

from pyspark.ml.feature import VectorAssembler

assembler = VectorAssembler(
    inputCols=["your", "independent", "variables"],
    outputCol="features")

transformed = assembler.transform(parsedData)

 

Next you can simply map:
 

from pyspark.mllib.regression import LabeledPoint
from pyspark.sql.functions import col

(transformed.select(col("outcome_column").alias("label"), col("features"))
  .rdd
  .map(lambda row: LabeledPoint(row.label, row.features)))

 

As of Spark 2.0 ml and mllib API are no longer compatible and the latter one is going towards deprecation and removal. If you still need this you'll have to convert ml.Vectors to mllib.Vectors. 
 

from pyspark.mllib import linalg as mllib_linalg
from pyspark.ml import linalg as ml_linalg

def as_old(v):
    if isinstance(v, ml_linalg.SparseVector):
        return mllib_linalg.SparseVector(v.size, v.indices, v.values)
    if isinstance(v, ml_linalg.DenseVector):
        return mllib_linalg.DenseVector(v.values)
    raise ValueError("Unsupported type {0}".format(type(v)))

 

and map:
 

lambda row: LabeledPoint(row.label, as_old(row.features)))
