在企业环境中，将tomcat里的日志和程序包统一到不同的路径，
自定义全局变量，自定义JAVA_OPTS都是很常见的操作。
现将相关文件作一示例，
以后可照猫画虎了。
（有时，tomcat日志的时间不对，系统的时间是对的，这里就要用GMT+8参数）
bin/setenv.sh
CLASSPATH=$CLASSPATH:/xxx/webconfigs
LOG_DIR="/xxx/weblogs/${MY_POD_NAMESPACE}_${MY_POD_NAME}"
JAVA_OPTS="$JAVA_OPTS -Duser.timezone=GMT+08"
JAVA_OPTS="$JAVA_OPTS -Dlog.home=${LOG_DIR}"
JAVA_OPTS="$JAVA_OPTS -Dxxx.log=${LOG_DIR}"
JAVA_OPTS="$JAVA_OPTS -Xms4096m -Xmx6144m -XX:MaxNewSize=512m -XX:MaxPermSize=512m"
JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=85 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps"
JAVA_OPTS="$JAVA_OPTS -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${LOG_DIR} -verbose:gc -Xloggc:${LOG_DIR}/gc.log"
