本文介绍了如何在CentOS 7中调整网卡启动顺序，将jbod的e1000e驱动调整到主柜的igb驱动之后。通过拷贝initramfs镜像、解压、编辑modules.dep文件、删除和添加驱动、重新压缩img文件，并更新grub配置来实现。

主柜的网卡的驱动是igb,jbod的网卡的驱动是e1000e。每次启动的时候都jbod的网卡的名称为eth0,eth1。需要调整

1 拷贝/home/initramfs-3.10.0-123.el7.x86_64.img到/home/images下

/usr/lib/dracut/skipcpio /home/images/initramfs-3.10.0-123.el7.x86_64.img | gunzip -c | cpio -i -d

2 解压后的目录情况

bin dev etc init lib lib64 proc root run sbin shutdown sys sysroot tmp usr var

3 查看modules.dep文件

cat usr/lib/modules/3.10.0-123.el7.x86_64/modules.dep

在usr/lib/modules/3.10.0-123.el7.x86_64/modules.dep文件中有e1000e驱动的加载

4 删除kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko: kernel/drivers/ptp/ptp.ko kernel/drivers/pps/pps_core.ko这一行

5 删除e1000e 驱动

rm -rf usr/lib/modules/3.10.0-123.el7.x86_64/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko

6 增加igb驱动

把kernel/drivers/net/ethernet/intel/igb/igb.ko: kernel/drivers/ptp/ptp.ko kernel/drivers/pps/pps_core.ko kernel/drivers/i2c/algos/i2c-algo-bit.ko kernel/drivers/dca/dca.ko kernel/drivers/i2c/i2c-core.ko

这一行添加到usr/lib/modules/3.10.0-123.el7.x86_64/modules.dep
