前提說明
OS信息：
Linux rel65 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Tomcat版本信息：
apache-tomcat-8.5.34
JDK版本信息：
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
錯誤描述
執行startup.sh腳本啓動tomcat服務時正常，但是使用相同用戶執行shutdown.sh腳本關閉tomcat服務時報錯，錯誤信息
ERROR: transport error 202: bind failed
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
修復辦法
將tomcat/bin/catalina.sh中的JAVA_OPTS去除遠程調試用的-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005，並增加到屬性CATALINA_OPTS中。
原因分析
這裏需要看下JAVA_OPTS和CATALINA_OPTS在catalina.sh腳本中的作用。
先查看下備註：
# CATALINA_OPTS (Optional) Java runtime options used when the "start",
# "run" or "debug" command is executed.
# Include here and not in JAVA_OPTS all options, that should
# only be used by Tomcat itself, not by the stop process,
# the version command etc.
# Examples are heap size, GC logging, JMX ports etc.
# JAVA_OPTS (Optional) Java runtime options used when any command
# is executed.
# Include here and not in CATALINA_OPTS all options, that
# should be used by Tomcat and also by the stop process,
# the version command etc.
# Most options should go into CATALINA_OPTS.
由註釋信息可知， CATALINA_OPTS屬性裏面的參數只會在start,run和debug時被執行調用，而JAVA_OPTS在執行任何命令時均會被調用。
因此當啓動時，兩個屬性裏面的參數均會被調用，所以原先遠程調試的參數均有效。但是當調用關閉服務命令時，JAVA_OPTS的參數會被再次調用，但此時端口號已經被佔用，所以會報端口占用的錯誤。而CATALINA_OPTS則不會有影響。
所以如註釋所說，大部分參數應當放到CATALINA_OPTS中。
