<>常用命令
<>查看进程与端口号
查看某个应用的进程号,比如查看tomcat的进程号(tomcat是否启动)
ps -ef | grep tomcat
ps -ef的意思是以长格式显示所有进程,grep tomcat是在所有进程里查找与字符tomcat有关的进程,并显示出来。
第一个root代表启动该tomcat的用户,第二个32298是该进程ID,第三个 是占用CPU的百分比,第四个是占用内存的百分比.
另外上面的那个21379代表的是你使用grep的这个进程。
根据进程号(PID)查看所占端口号:
netstat -anop | grep 32298
得知tomcat占用端口号80,这里面还有8009和8005,这个都是默认对tomcat做监听的一些端口,比如8005,当执行shutdown.sh关闭tomcat时就是连接8005端口执行“SHUTDOWN”命令。
<>查看端口占用情况
lsof -i:80 查看80端口占用的进程信息等
<>防火墙相关
查看防火墙状态 systemctl status firewalld
关闭防火墙 systemctl stop firewalld
开启防火墙 systemctl start firewalld
<>查找所在目录
