我已经启动了一个容器,打开了一些端口,并试图通过浏览器访问Tomcat的web接口,但它不起作用。
1)docker run -ti --rm --name server -p 3456:5678 tomcat:8.0 // not working with localhost:3456
2)docker run -ti --rm --name server -expose 8080 tomcat:8.0 //not working localhost:8080
3)docker inspect server // to see the ip:port and tried to access
我已经按照命令在CentOS7中安装了httpd服务。
sudo yum install epel-release -y
sudo yum update -y
sudo yum install httpd -y

Failed to start httpd.service: Activation of org.freedesktop.systemd1 timed out
See system logs and 'systemctl status httpd.service' for details.
尝试使用sudo systemctl start httpd.ser

host all all 0.0.0.0/0 md5
host all all ::/0
