执行ps -ef |grep tomcat 输出如下
sun 5144 1 0 10:21 pts/1 00:00:06 /java/jdk/bin/java -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/java/tomcat/common/endorsed -classpath :/java/tomcat/bin/bootstrap.jar:/java/tomcat/bin/commons-logging-api.jar -Dcatalina.base=/java/tomcat -Dcatalina.home=/java/tomcat -Djava.io.tmpdir=/java/tomcat/temp org.apache.catalina.startup.Bootstrap start
说明tomcat已经正常启动， 5144 就为进程号 pid = 5144
杀死
kill -9 5144
