查看是否安装tomcat及其版本

rpm -qa|grep tomcat

[root@iz2ze671n0mnfxavn3oh3fz bin]# rpm -qa|grep tomcat
tomcat-servlet-3.0-api-7.0.76-8.el7_5.noarch
[root@iz2ze671n0mnfxavn3oh3fz bin]# 

查看tomcat进程id

[root@iz2ze671n0mnfxavn3oh3fz bin]# ps -ef|grep tomcat
root      3823 25457  0 14:14 pts/0    00:00:00 grep --color=auto tomcat

查找文件位置路径

sudo find / -name *tomcat*

[root@localhost /]# sudo find / -name *tomcat*
/etc/selinux/targeted/active/modules/100/tomcat
/home/ucp/install_fusionsbc/fusionsbc/tomcat7

/home/ucp/fusionsbc/tomcat7
/home/ucp/fusionsbc/tomcat7/bin/tomcat-juli.jar
/home/ucp/fusionsbc/tomcat7/conf/tomcat-users.xml
/home/ucp/fusionsbc/tomcat7/lib/tomcat-api.jar
[root@localhost /]# 

查看进程

vim中查看文件编码格式：:set fileencoding
查看tomcat进程：ps -ef|grep tomcat
用于显示tcp，udp的端口和进程等相关情况：

[root@iz2ze671n0mnfxavn3oh3fz tomcat7]# netstat -tunlp

显示出所有的java进程，去处掉当前的grep进程：ps -ef|grep java|grep -v grep
查看历史命令：history
查看日志：tail -f 日志名
