首先查找tomcat进程id

ps -ef|grep java

可能会查出很多例如：

root      1974     1  0 17:47 ?        00:00:03 ../jdk1.6.0_16/bin/java -Djava.security.policy=./policy.all -Djava.rmi.server.codebase=file:../dist/bca.jar com.bca.agent.dagent.DAgent
root      2042     1  0 17:47 ?        00:00:05 ../jdk1.6.0_16/bin/java -Djaer.useLocalHostname=true -Djava.security.policy=./policy.all com.bca.agent.cms.BcaCms
root      2162     1  0 17:47 ?        00:00:04 ../jdk1.6.0_16/bin/java -Djava.rmi.server.useLocalHostname=true -Djava.security.policy=./policy.all com.bca.agent.ivr.IVR
root      2242     1  0 17:47 ?        00:00:02 ../jdk1.6.0_16/bin/java -Djava.security.policy=./policy.all com.bca.agent.cms.ccdc.BcaCCDC
root      2716  2711  0 17:58 pts/1    00:00:03 /usr/java/jdk1.6.0_25/bin/java -Djava.util.logging.config.file=/usr/tomcat7.0.11/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/tomcat7.0.11/endorsed -classpath /usr/tomcat7.0.11/bin/bootstrap.jar:/usr/tomcat7.0.11/bin/tomcat-juli.jar -Dcatalina.base=/usr/tomcat7.0.11 -Dcatalina.home=/usr/tomcat7.0.11 -Djava.io.tmpdir=/usr/tomcat7.0.11/temp org.apache.catalina.startup.Bootstrap start
root      3498 30883  0 18:29 pts/1    00:00:00 grep java

可以看到红色字体的为tomcat进程，id为2716

然后运行命令：kill -9 2716即可
