CentOS Network Problem Summary

One, unable to access the CentOS network under Windows

1. View the firewall

#/etc/init.d/iptables status

#/etc/init.d/iptabels Stop//firewall off

#iptables-I input-p TCP--dport 80-j ACCEPT

2. View httpd Status

#/etc/init.d/httpd status

#/etc/init.d/httpd Restart//Direct restart

3. Try to refresh the webpage. (check if IP is wrong)

Second, CentOS7 minimal installation on no ifconfig command

#yum provides ifconfig

Or

#yum Whatprovides Ifconfig

#yum-y Install Net-tools

#ifconfig-A Can

Third, CentOS can ping through windows, but Windows cannot ping CentOS. (under VirtualBox virtual machine)

WORKAROUND: Set the network as a bridge network card, then perform

#service Network Restart

At this point, Windows has access to CentOS, but CentOS cannot ping windows.

D. Enable Apache to boot with the system

#chkconfig--levels 235 httpd on

Or

#chkconfig httpd on

Configuration complete, restart Apache

#/etc/init.d/httpd restart

In CentOS, the default root directory for Apache is/var/www/html, configuration file/etc/httpd/conf/httpd.conf, and other configurations stored in the/etc/httpd/conf.d/directory.
