Rocky Linux优化

一、修改网卡名称为eth
1、方法一（在安装系统时修改）：

# 进入启动菜单后按Tab键，在quiet后添加net.ifnames=0 biosdevname=0
> vmlinuz initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 quiet net.ifnames=0 biosdevname=0

2、方法二（安装完系统修改）
[root@Rocky9 ~]# cat /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="resume=UUID=399b90b6-59a3-4416-b248-3edfc297c32f biosdevname=0 net.ifnames=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

[root@Rocky9 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
[root@Rocky9 ~]# reboot
二、网卡配置
[root@Rocky9 ~]# cat /etc/NetworkManager/system-connections/eth0.nmconnection

[connection]

[root@Rocky9 ~]# nmcli con down eth0 && nmcli con up eth0
