Centos 7常用操作记录

进程相关

搜索某一个进程(以进程Server为例)

ps -ef | grep 进程名 # 根据进程名查看进程信息

netstat -tunlp | grep 端口号 # 根据端口查看对应进程，查看占用8080端口的进程id

举例

ps -ef | grep Server

netstat -tunlp | grep 8080

关闭进程

kill -9 端口号

举例：例如要关闭端口号为8088的进程

kill -9 8088

防火墙相关

放行端口

firewall-cmd --zone=public --add-port=4568/tcp --permanent   # 开放4568端口

firewall-cmd --zone=public --remove-port=4567/tcp --permanent  #关闭4567端口

firewall-cmd --reload   # 配置立即生效

基本命令

查看当前命令

pwd

用管理员权限打开文件管理器

sudo nautilus

chmod +x /etc/rc.d/init.d/xiaomiqiu_start.sh
cd /etc/rc.d/init.d
chkconfig --add xiaomiqiu_start.sh
sudo chkconfig --level 345 xiaomiqiu_start.sh on
sed -i 's/\r$//'  xiaomiqiu_start.sh

sudo chmod +x /etc/rc.d/rc.local
sudo chmod +x /etc/rc.d/init.d/xiaomiqiu_start.sh
ps -ef | grep xiaomiqiu
