9. 查詢指令
man ps
# 刪除資料夾↓

# 改名↓
sudo mv foo foo_ori_1012
sudo mv webpack.config.js webpack.config.js_1012
# 查詢使用port↓
sudo lsof -i :3000 | grep LISTEN
# 移除佔用port↓
sudo kill $(sudo lsof -t -i:3000)
# 列出所有程序↓
ps aux
sudo kill 16406
# 傳送資料夾↓
pscp -r -pw password C:\ssm\locales user@127.0.0.1:/home/social/ssm

#pscp root@192.168.2.8:/srv/docker/gitlab d:\gitlab
# = = = 防火牆設定(centOS 7) = = =
# 開啟6379port --permanent為設置永久
firewall-cmd --zone=public --add-port=6379/tcp --permanent
# 確認防火牆是否開啟
firewall-cmd --zone=public --list-all

修改網路設定 $ sudo vi /etc/network/interfaces
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
# post-up iptables-restore < /etc/iptables.up.rules
auto eth1
iface eth1 inet static
address 192.168.2.184
netmask 255.255.255.0
# geteway 192.168.2.1
網路重啟
sudo /etc/init.d/networking restart
sudo ifdown eth0 && sudo ifup eth0
sudo ifdown eth1 && sudo ifup eth1
