linux下tomcat注意配置事项

一、加大tomcat启动时的内存大小

(1)tomcat\bin目录下面的catalina.sh这个文件。

(2)

# Set juli LogManager if it is present
if [ -r "$CATALINA_HOME"/bin/tomcat-juli.jar ]; then
  JAVA_OPTS="$JAVA_OPTS -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
  LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties"
else
  # Bugzilla 45585
  LOGGING_CONFIG="-Dnop"
fi

# ----- Execute The Requested Command -----------------------------------------

 

#add by duyf from 10.3.3.27
echo set JAVA_OPTS
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8139 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Xms1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"
echo JAVA_OPTS=$JAVA_OPTS
#add ends

 

# Bugzilla 37848: only output this if we have a TTY
if [ $have_tty -eq 1 ]; then
  echo "Using CATALINA_BASE:   $CATALINA_BASE"
  echo "Using CATALINA_HOME:   $CATALINA_HOME"
  echo "Using CATALINA_TMPDIR: $CATALINA_TMPDIR"
  if [ "$1" = "debug" -o "$1" = "javac" ] ; then
    echo "Using JAVA_HOME:       $JAVA_HOME"
  else
    echo "Using JRE_HOME:       $JRE_HOME"
  fi
fi

 

(3)或者下面这样的写法也可以。

CATALINA_OPTS="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8839
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Xms512m
-Xmx1024m
-Djava.awt.headless=true"

export CATALINA_OPTS

DISPLAY="127.0.0.1:0.0"
export DISPLAY

 

#add by duyf

JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=2048m -XX:MaxPermSize=2048m -Djava.awt.headless=true"
export  JAVA_OPTS

#end

# OS specific support.  $var _must_ be set to either true or false.
cygwin=false
os400=false
case "`uname`" in
CYGWIN*) cygwin=true;;
OS400*) os400=true;;
esac

 

二、项目放到tomcat下面来运行

(1)写个xml的配置文件放到D:\apache-tomcat-5.5.26\conf\Catalina\localhost下面，格式如下：

<?xml version="1.0" encoding="UTF-8"?>

<Context docBase="D:\project\momc2.0\java\moio\html" path="/moio" reloadable="false" privileged="true"/>

注意这里的docBase所指的目录是到WEB-INF这个目录的上面即可。因为WEB-INF这个目录下有classes源码。

<?xml version="1.0" encoding="UTF-8"?>

<Context docBase="D:\project\momc2.0\java\momc2" path="/momc2" reloadable="false" privileged="true"/>

或者这样

<?xml version="1.0" encoding="UTF-8"?>

<Context docBase="D:\solodu\workspace\momc3\WebRoot" path="/momc3" reloadable="false" privileged="true" antiResourceLocking="false" antiJARLocking="false"/>

 

(2)也可以这样来配置在tomcat/conf/server.xml文件里面：

<Context path="/momc" docBase="/mimsm/momc/test/momctest_szty"  debug="0"  reloadable="true" crossContext="true"/>
<Context path="/aaaa" docBase="/mimsm/momc/test/moiotest_szty" debug="0" reloadable="ture" crossContext="true"/>

在</Host>标签的上发紧挨着放即可！
