上面最后会输出swap分区的新的uuid,把这个新的uuid填到/etc/fstab就能够了。git
debian下使用#!/bin/bash替换#!/bin/shgithub
打包的容量从5.1G降低到2.3G,效果仍是很明显的。ubuntu
上面打包获得的镜像文件,这个在编译文件的时候遇到问题:bash
解决: g++: internal compiler error: Killed (program cc1plus)app
g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, 主要缘由大致上是由于内存不足,有点坑 临时使用交换分区来解决吧 sudo dd if=/dev/zero of=/swapfile bs=64M count=16 sudo mkswap /swapfile sudo swapon /swapfile After compiling, you may wish to Code: sudo swapoff /swapfile sudo rm /swapfile
最后发现是vagrant镜像从新初始化后,swap分区没有挂载上致使上面的状况出现,咱们要从新挂载这个swap分区。less
1. 肯定swap分区没有挂载:curl
cat /proc/swaps Filename Type Size Used Priority
上面没有显示挂载的分区,那就是没有挂载上。ide
2.肯定swap分区所在:
#fdisk -l Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 40136703 40134656 19.1G 83 Linux /dev/sda2 40138750 41940991 1802242 880M 5 Extended /dev/sda5 40138752 41940991 1802240 880M 82 Linux swap / Solaris
能够看到/dev/sda5 的分区类型是linux swap / Solaris,这个就是咱们要挂载的swap分区。
3. 肯定swap分区的uuid,
# blkid /dev/sda5 /dev/sda5: UUID="c41a274b-d2b4-4f33-8188-e75da63adade" TYPE="swap" PARTUUID="1abd93b2-05"
/dev/sda5 的uuid就是c41a274b-d2b4-4f33-8188-e75da63adade
4.修改/etc/fstab,使系统自动挂载上。添加下面的选项:
UUID=c41a274b-d2b4-4f33-8188-e75da63adade none swap sw 0 0
5.挂载全部分区,
mount -a
或者重启就能够了。
