Ubuntu 开放指定端口
2021-05-27
一般情况下，ubuntu安装好的时候，iptables会被安装上，如果没有的话先安装sudo apt-get install iptables
添加开放端口
# sudo iptables -I INPUT -p tcp --dport [端口号] -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT
# 临时保存配置，重启后失效
sudo iptables-save安装 iptables-persistent工具，持久化开放端口配置sudo apt-get install iptables-persistent
sudo netfilter-persistent save
sudo netfilter-persistent reloadRecommend
