Linux下如何查看tomcat是否启动，并杀死重启
在Linux系统下，遇到过这样的问题，项目中使用
./shutdown.sh
关闭Tomcat失败
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.7.0_80
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

首先，查看Tomcat是否以关闭
ps -ef|grep java
如果显示以下相似信息，说明Tomcat还没有关闭

这里有很多，根据自己配置的查看就行。
杀死Tomcat进程
kill -9 28107
再次查看Tomcat是否关闭

可以看到这里关闭了一个Tomcat的进程了，再启动
[root@instance-5f71uexu bin]# cd /usr/local/tomcat/bin
[root@instance-5f71uexu bin]# ./startup.sh
