我正在尝试使用openldap for rabbitmq auth。 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:
如何使用shell输入启动rabbitmq-server,因此可以在线调试。默认情况下,ps -ef显示rabbitmq以noshell
开头。如何改变?
yus-iMac:ebin yuchen $ ps -ef | grep erl

我检查了启动脚本“rabbitmq-server”
exec ${ERL_DIR}erl \
-pa ${RABBITMQ_EBIN_ROOT} \
${RABBITMQ_START_RABBIT} \

-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 "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

listen_arg: -rabbit tcp_listeners [{"127.0.0.1",5672}]
只有'没有输入',但不存在“noshell
”,ps -ef
的输出noshell
来自何处?
我用新的替换了“rabbit_auth_backend_ldap.beam”。但重新启动rabbitmq-server后,连接它,但调试信息不在rabbitmq日志中。 似乎我的新工作不起作用。

更改后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.
在rabbitmq-server重启后日志没有变化。

答案 0 :(得分:0)
虽然此错误可能与其他内容有关,但是在RabbitMQ 3.3.5上可能导致此错误的一个条件是包含感叹号的密码用户名:&#34;!&#34;
