See which component contains ifconfig command
yum provides ifconfig
或
yum whatprovides ifconfig
ifconfig command depends on the net-tools, installation
yum install -y net-tools
Installation vim editor 3.3
yum install -y vim-enhanced3.4 install wget
yum install -y wget3.5 Close SELinux
SELinux configuration file editing
vim /etc/selinux/configComment out line 2, and the last line of code was added 1
#SELINUX=enforcing
#SELINUXTYPE=targeted
SELINUX=disabledSave and close the setting is enabled, it is best to restart the system, you can restart later
setenforce 0Close CentOS 3.6 comes with firewall firewall, enable iptables
# 停止firewall
[root@centos7 /]# systemctl stop firewalld
# 关闭firewall自动启动
