我在Ubuntu 14.04上安装了rabbitmq。在阅读配置文档时，我想在/etc/rabbitmq/rabbitmq.config中创建自己的rabbitmq.config文件，因此我搜索了/usr/share/doc/rabbitmq-server/rabbitmq.config.example.gz下的配置文件示例。
我在/etc/rabbitmq/rabbitmq.config解压缩并开始取消注释许多选项。一旦我尝试通过sudo service rabbitmq-server restart重启rabbitmq就失败了。我查看了日志，发现以下错误：
==> /var/log/rabbitmq/startup_log <==
{"could not start kernel pid",application_controller,"error in config file \"/etc/rabbitmq/rabbitmq.config\" (214): syntax error before: ']'"}
所以我虽然没有正确地编写其中一个选项，但我试图修复第214行，但第214行是第一部分的配置字典的结尾。我删除了文件，并从头开始重新思考，我会逐行取消注释，重新启动每个取消注释之间的rabbitmq，以找到我在哪一行发生错误。
我做的第一件事就是取消注释我不需要像这样修改的一行：
%% {reverse_dns_lookups, true}, %% I only removed the % signs
它没有改变任何它无法重启rabbitmq-server在第214行抛出完全相同的语法错误。我检查了列表和字典的开始和结束的位置，一切看起来都很好。顺便说一句，如果你保持文件不变，它将允许你重新启动rabbitmq。
我忘记取消注释此文件中的内容吗？

%% Network Connectivity
%% ====================
%%
%% By default, RabbitMQ will listen on all interfaces, using
%% the standard (reserved) AMQP port.
%%
%% {tcp_listeners, [5672]},
%% To listen on a specific interface, provide a tuple of {IpAddress, Port}.
%% For example, to listen only on localhost for both IPv4 and IPv6:
%%
%% {tcp_listeners, [{"127.0.0.1", 5672},
%% {"::1", 5672}]},
%% SSL listeners are configured in the same fashion as TCP listeners,
%% including the option to control the choice of interface.
%%
%% {ssl_listeners, [5671]},
%% Log levels (currently just used for connection logging).
%% One of 'info', 'warning', 'error' or 'none', in decreasing order
%% of verbosity. Defaults to 'info'.
%%
%% {log_levels, [{connection, info}]},
%% Set to 'true' to perform reverse DNS lookups when accepting a
%% connection. Hostnames will then be shown instead of IP addresses
%% in rabbitmqctl and the management plugin.
%%
%% {reverse_dns_lookups, true},
%%
%% Security / AAA

%% {fail_if_no_peer_cert, false}]},
%% Choose the available SASL mechanism(s) to expose.
%% The two default (built in) mechanisms are 'PLAIN' and
%% 'AMQPLAIN'. Additional mechanisms can be added via
%% plugins.
%%
%% See http://www.rabbitmq.com/authentication.html for more details.
%%
%% {auth_mechanisms, ['PLAIN', 'AMQPLAIN']},
%% Select an authentication database to use. RabbitMQ comes bundled
%% with a built-in auth-database, based on mnesia.

%% Configurations supporting the rabbitmq_auth_mechanism_ssl and
%% rabbitmq_auth_backend_ldap plugins.
%%
%% NB: These options require that the relevant plugin is enabled.
%% See http://www.rabbitmq.com/plugins.html for further details.
%% The RabbitMQ-auth-mechanism-ssl plugin makes it possible to
%% authenticate a user based on the client's SSL certificate.
%%
%% To use auth-mechanism-ssl, add to or replace the auth_mechanisms
%% list with the entry 'EXTERNAL'.
%%
%% {auth_mechanisms, ['EXTERNAL']},
%% The rabbitmq_auth_backend_ldap plugin allows the broker to
%% perform authentication and authorisation by deferring to an
%% external LDAP server.
%%
%% For more information about configuring the LDAP backend, see
%% http://www.rabbitmq.com/ldap.html.
%%
%% Enable the LDAP auth backend by adding to or replacing the
%% auth_backends entry:
%%
%% {auth_backends, [rabbit_auth_backend_ldap]},
%% This pertains to both the rabbitmq_auth_mechanism_ssl plugin and
%% STOMP ssl_cert_login configurations. See the rabbitmq_stomp

%% ====================
