1.修改主机名
hostnamectl set-hostname
2.ssh连接慢的问题解决
vim /etc/ssh/sshd_config
UseDNS=no
GSSAPIAuthentication
重启sshd
systemctl restart sshd
3.安装系统要做的事情
关闭selinux
vim /etc/selinux/config
SELINUX=disabled
关闭防火墙
systemctl stop firewalld systemctl disable firewalld
修改网卡名字
cd /etc/sysconfig/network-scripts/ mv ifcfg-enp0s3 ifcfg-eth0 mv ifcfg-enp0s8 ifcfg-eth1
并修改内容，定制静态IP
修改网卡配置文件中的 DEVICE=参数的关于 eth0 ，eth1等
因 CentOS7 采用 grub2 引导，还需要对 grub2 进行修改，编辑/etc/default/grub 配置文件，在 GRUB_CMDLINE_LINUX这个参数后面加入 net.ifnames=0 biosdevname=0
[[email protected] network-scripts]# vi /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed ‘s, release .*$,,g‘ /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0" GRUB_DISABLE_RECOVERY="true"
用 grub2-mkconfig 命令重新生成GRUB配置并更新内核
[[email protected] network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-327.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-4dd6b54f74c94bff9e92c61d669fc195 Found initrd image: /boot/initramfs-0-rescue-4dd6b54f74c94bff9e92c61d669fc195.img done
