Erlang 如何调试rabbitmq ldap代码？

我正在尝试将openldap用于rabbitmq身份验证。 但是在监视openldap日志时，它总是有错误信息

计划通过替换ebin文件将调试代码插入rabbitmq的源代码中

两个问题:

如何使rabbitmq服务器以shell输入启动，以便可以在线调试。默认情况下，ps-ef show rabbitmq从noshell开始。如何改变它

yus iMac:ebin yuchen$ps-ef | grep erl

我已经检查了rabbitmq服务器的启动脚本

exec ${ERL_DIR}erl \
    -pa ${RABBITMQ_EBIN_ROOT} \
    ${RABBITMQ_START_RABBIT} \
    -sname ${RABBITMQ_NODENAME} \
    -boot "${SASL_BOOT_FILE}" \
    ${RABBITMQ_CONFIG_ARG} \
    +W w \
    ${RABBITMQ_SERVER_ERL_ARGS} \
    ${RABBITMQ_LISTEN_ARG} \
    -sasl errlog_type error \
    -sasl sasl_error_logger false \
    -rabbit error_logger '{file,"'${RABBITMQ_LOGS}'"}' \
    -rabbit sasl_error_logger '{file,"'${RABBITMQ_SASL_LOGS}'"}' \
    -rabbit enabled_plugins_file "\"$RABBITMQ_ENABLED_PLUGINS_FILE\"" \
    -rabbit plugins_dir "\"$RABBITMQ_PLUGINS_DIR\"" \
    -rabbit plugins_expand_dir "\"$RABBITMQ_PLUGINS_EXPAND_DIR\"" \
    -os_mon start_cpu_sup false \
    -os_mon start_disksup false \
    -os_mon start_memsup false \
    -mnesia dir "\"${RABBITMQ_MNESIA_DIR}\"" \
    ${RABBITMQ_SERVER_START_ARGS} \
    "$@" 

添加以下调试代码

echo "erl dir:" ${ERL_DIR}
echo "pa:" ${RABBITMQ_EBIN_ROOT} 
echo "ebin_root:" ${RABBITMQ_EBIN_ROOT}
echo "boot:" ${SASL_BOOT_FILE}
echo "start rabbit:"  ${RABBITMQ_START_RABBIT}
echo "config_args:" ${RABBITMQ_CONFIG_ARG}
echo "server_erl_args:" ${RABBITMQ_SERVER_ERL_ARGS}
echo "listen_arg:"  ${RABBITMQ_LISTEN_ARG}

调试结果如下：

erl dir: /usr/local/Cellar/rabbitmq/3.1.5/erts-5.10.2/bin/
pa: /usr/local/Cellar/rabbitmq/3.1.5/ebin
ebin_root: /usr/local/Cellar/rabbitmq/3.1.5/ebin
boot: /usr/local/Cellar/rabbitmq/3.1.5/releases/3.1.5/start_sasl
start rabbit: -noinput -s rabbit boot
config_args: -config /usr/local/etc/rabbitmq/rabbitmq
server_erl_args: +K true +A30 +P 1048576 -kernel inet_default_connect_options [{nodelay,true}]
listen_arg: -rabbit tcp_listeners [{"127.0.0.1",5672}]

只有“无输入”，但不存在noshell，ps-ef的输出noshell从何而来

我已经用新的替换了rabbit\u auth\u backend\u ldap.beam。但重启rabbitmq服务器并连接后，调试信息不在rabbitmq日志中。 看来我的新工作不顺利

yus iMac:ebin yuchen$pwd /usr/local/ceral/rabbitmq/3.1.5/plugins/expand/rabbitmq\u auth\u backend\u ldap-3.1.5/ebin

更改的文件部分代码如下，我在模板后添加了111：

log(_Fmt, _Args, #state{log = false}) -> ok;
log( Fmt,  Args, _State)              -> rabbit_log:info(Fmt ++ "~n", Args).

fill(Fmt, Args, State) ->
    ?L2("filling template111 \"~s\" with~n            ~p", [Fmt, Args], State),
    R = rabbit_auth_backend_ldap_util:fill(Fmt, Args),
    ?L2("template result: \"~s\"", [R], State),
    R.

rabbitmq服务器重新启动后，日志不会更改

虽然此错误可能与其他错误有关，但在RabbitMQ 3.3.5上可能导致此错误的一个条件是用户名的密码包含感叹号：
