让JBoss允许外部电脑连接

/opt/app/bin/cfg # ip addr show eth0 up 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 22:05:7f:74:91:04 brd ff:ff:ff:ff:ff:ff inet 192.168.0.113/24 brd 192.168.0.255 scope global eth0 valid_lft forever preferred_lft forever /opt/app/bin/cfg # ip addr show eth0 up | grep -q 192.168.0.113/24 并没有返回真，为什么

ip addr show | grep -w inet | grep -v "inet6" | awk '{print $2}' 赋予变量

debian网络配置

JBoss只能localhost或127.0.0.1访问无法用ip地址

使用 Dockerfile 完成一个 Nginx 镜像，要求 Dockerfile 文件中体现以下内 容： （1）基于基础镜像centos； （2）Dockerfile 中添加标记或者维护者信息 （3）在线下载软件包 nginx‐1.23.3.tar.gz，解压后删除 nginx 的下载包； （4）编译安装 nginx 后，删除 nginx 解压的文件夹； （5）设置 nginx 执行路径的环境变量； （6）将nginx里 index.html的文件内容是

Welcome to nginx!
