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_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.#                   Defaults to $CATALINA_HOME/endorsed.##   JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"#                   command is executed. The default is "dt_socket".##   JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"#                   command is executed. The default is 8000.##   JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"#                   command is executed. Specifies whether JVM should suspend#                   execution immediately after startup. Default is "n".##   JPDA_OPTS       (Optional) Java runtime options used when the "jpda start"#                   command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,#                   and JPDA_SUSPEND are ignored. Thus, all required jpda#                   options MUST be specified. The default is:##                   -agentlib:jdwp=transport=$JPDA_TRANSPORT,#                       address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND##   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"# -----------------------------------------------------------------------------JAVA_OPTS='-Xms8192m -Xmx8192m' ---设置内存大小export JAVA_HOME=/usr/java/jdk1.8.0_20# OS specific support.  $var _must_ be set to either true or false.cygwin=falsedarwin=falseos400=falsecase "`uname`" inCYGWIN*) cygwin=true;;Darwin*) darwin=true;;OS400*) os400=true;;esac
