关于远程debug
原因：一般公司集群只有三种环境，开发，集成，生产。而开发库往往数据量比较少或者没有数据，导致无法调试，需要连接到集成打日志。但每次打日志都要修改代码，并重启。给我带来了不小的麻烦，浪费开发时间。
解决：通过远程连接到集成服务器，代码debug调试，监听。
步骤：
- 首先确保本地和服务器的代码一致（入不一致需要替换jar包）
- 集成库替换/data/platform-web-server/bin/catalina.sh

Instead put them into a script # setenv.sh in CATALINA_BASE/bin to keep your customizations separate. # # CATALINA_HOME May point at your Catalina "build" directory. # # CATALINA_BASE (Optional) Base directory for resolving dynamic portions # of a Catalina installation. If not present, resolves to # the same directory that CATALINA_HOME points to. # # CATALINA_OUT (Optional) Full path to a file where stdout and stderr # will be redirected. # Default is $CATALINA_BASE/logs/catalina.out # # CATALINA_OUT_CMD (Optional) Command which will be executed and receive # as its stdin the stdout and stderr from the Tomcat java # process. If CATALINA_OUT_CMD is set, the value of # CATALINA_OUT will be ignored. # No default. # Example (all one line) # CATALINA_OUT_CMD="cronolog $CATALINA_BASE/logs/catalina.%Y-%m-%d.out >/dev/null 2>&1" # # 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. # # CATALINA_TMPDIR (Optional) Directory path location of temporary directory # the JVM should use (java.io.tmpdir). Defaults to # $CATALINA_BASE/temp. # # JAVA_HOME Must point at your Java Development Kit installation. # Required to run the with the "debug" argument. # # JRE_HOME Must point at your Java Runtime installation. # Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME # are both set, JRE_HOME is used. # # 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. # # JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories # containing some jars in order to allow replacement of APIs # created outside of the JCP (i.e. DOM and SAX from W3C). # It can also be used to update the XML parser implementation. # This is only supported for Java <= 8. # Defaults to $CATALINA_HOME/endorsed. # # JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start" # command is executed. The default is "dt_socket". # # JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start" # command is executed. The default is localhost:8000. # # JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start" # command is executed. Specifies whether JVM should suspend # execution immediately after startup. Default is "n". # # JPDA_OPTS (Optional) Java runtime options used when the "jpda start" # command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS, # and JPDA_SUSPEND are ignored. Thus, all required jpda # options MUST be specified. The default is: # # -agentlib:jdwp=transport=$JPDA_TRANSPORT, # address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND # # JSSE_OPTS (Optional) Java runtime options used to control the TLS # implementation when JSSE is used. Default is: # "-Djdk.tls.ephemeralDHKeySize=2048" # # CATALINA_PID (Optional) Path of the file which should contains the pid # of the catalina startup java process, when start (fork) is # used # # LOGGING_CONFIG (Optional) Override Tomcat's logging config file # Example (all one line) # LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties" # # LOGGING_MANAGER (Optional) Override Tomcat's logging manager # Example (all one line) # LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager" # # UMASK (Optional) Override Tomcat's default UMASK of 0027 # # USE_NOHUP (Optional) If set to the string true the start command will # use nohup so that the Tomcat process will ignore any hangup # signals. Default is "false" unless running on HP-UX in which # case the default is "true" # ----------------------------------------------------------------------------- #Version 20190118 # OS specific support. $var _must_ be set to either true or false. export JAVA_OPTS='-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999' cygwin=false darwin=false os400=false hpux=false case "`uname`" in CYGWIN*) cygwin=true;; Darwin*) darwin=true;; OS400*) os400=true;; HP-UX*) hpux=true;; esac # resolve links - $0 may be a softlink PRG="$0" while [ -h "$PRG" ]; do ls=`ls -ld "$PRG"` link=`expr "$ls" : '.*-> \(.*\)$'` if expr "$link" : '/.*' > /dev/null; then PRG="$link" else PRG=`dirname "$PRG"`/"$link" fi done # Get standard environment variables PRGDIR=`dirname "$PRG"` # Only set CATALINA_HOME if not already set [ -z "$CATALINA_HOME" ] && CATALINA_HOME=`cd "$PRGDIR/.." >/dev/null; pwd` # Copy CATALINA_BASE from CATALINA_HOME if not already set [ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME" # Ensure that any user defined CLASSPATH variables are not used on startup, # but allow them to be specified in setenv.sh, in rare case when it is needed.
