Graylog with Nginx Reverse Proxy (Centos 7)


(Adam Birds) #1

My Setup is as follows:

    server {

            server_name graylog.example.com;

    ############################
    # GRAYLOG CONFIGURATION FILE
    ############################
    #
    # This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
    # Characters that cannot be directly represented in this encoding can be written using Unicode escapes
    # as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
    # For example, \u002c.
    # 
    # * Entries are generally expected to be a single line of the form, one of the following:
    #
    # propertyName=propertyValue
    # propertyName:propertyValue
    #
    # * White space that appears between the property name and property value is ignored,
    #   so the following are equivalent:
    # 
    # name=Stephen
    # name = Stephen
    #
    # * White space at the beginning of the line is also ignored.
    #
    # * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
    #
    # * The property value is generally terminated by the end of the line. White space following the
    #   property value is not ignored, and is treated as part of the property value.
    #
    # * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
    #   For example:
    #
    # targetCities=\
    #         Detroit,\
    #         Chicago,\
    #         Los Angeles
    #
    #   This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
    # 
    # * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
    # 
    # * The backslash character must be escaped as a double backslash. For example:
    # 
    # path=c:\\docs\\doc1
    #

Fixed it, turns out it was Elasticsearch 6 that was causing the issue. Downgraded to 5 something and that fixed it.
