Tomcat调优及启动脚本

实验平台:CentOS 6.8
实验IP:10.113.128.1
Tomcat版本:



一、JAVA_OPTS参数

JAVA_OPTS="
-server             #一定要作为第一个参数,在多个CPU时性能佳
-Xms1024m           #初始Heap堆大小,使用的最小内存,cpu性能高时此值应设的大一些
-Xmx1024m           #java heap最大值,使用的最大内存
#上面两个值是分配JVM的最小和最大内存,取决于硬件物理内存的大小,建议均设为物理内存的一半。
-XX:PermSize=169m   #设定内存的永久保存区域
-XX:MaxPermSize=169m    #设定最大内存的永久保存区域
-Xmn678m        #young generation的heap大小,一般设置为Xmx的3、4分之一
-Xss256K        #每个线程的Stack大小
-XX:+CMSClassUnloadingEnabled
-XX:+UseParNewGC        #缩短minor收集的时间
-XX:+CMSParallelRemarkEnabled
-XX:SoftRefLRUPolicyMSPerMB=0
-XX:+UseFastAccessorMethods
-XX:+UseConcMarkSweepGC         #缩短major收集的时间
-XX:+DisableExplicitGC
-XX:ParallelGCThreads=10
-XX:CMSFullGCsBeforeCompaction=0
-XX:+UseCMSCompactAtFullCollection
-XX:SurvivorRatio=4
-XX:LargePageSizeInBytes=128m
-XX:+UseCMSInitiatingOccupancyOnly
-XX:CMSInitiatingOccupancyFraction=70
-XX:+UseCompressedOops
-XX:+CMSScavengeBeforeRemark
-XX:MaxTenuringThreshold=15
-XX:TargetSurvivorRatio=90
-XX:+HeapDumpOnOutOfMemoryError
-XX:+ShowMessageBoxOnError
-Djava.rmi.server.hostname=10.113.128.1     #使用JAVA自带工具查看jvm使用情况
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=10001
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-XX:+UnlockCommercialFeatures

-Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000
-Dsun.lang.ClassLoader.allowArraySyntax=true
-Djava.awt.headless=true"
#待续。。。

二、Tomcat几个通用启动脚本

echo "执行备份"

#集成备份,更新功能
