Ubuntu中Swap分区挂载

Q：在Ubuntu系统安装成功之后，当Swap分区丢失或者修改大小之后，如何再挂载以及如何开机自动挂载Swap分区？ A：手动挂载Swap分区使用command：swapon eg: ~$ sudo swapon /dev/sda5 NAME swapon, swapoff - enable/disable devices and files for paging and swap‐ ping SYNOPSIS Get info: swapon -s [-h] [-V] Enable/disable: swapon [-f] [-p priority] [-v] specialfile... swapoff [-v] specialfile... Enable/disable all: swapon -a [-e] [-f] [-v] swapoff -a [-v] More information: man swapon 开机自动挂载：把Swap分区的UUID放到/etc/fstab文件中 # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=92182c1f-033f-4c75-a727-00294285a8d9 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda6 during installation UUID=aed858e1-2a3f-4b4a-b13c-656e1b24554b /boot ext4 defaults 0 2 # /home was on /dev/sda8 during installation UUID=0a63aa06-8adb-47ea-9116-ed2ea0e28a5c /home ext4 defaults 0 2 # swap was on /dev/sda5 during installation UUID=3ba1745f-1726-484f-a557-761a72073c04 none swap sw 0 0 查看UUID：ls -l /dev/disk/by-uuid zhujia@Zhujia:~$ ls -l /dev/disk/by-uuid/ total 0 lrwxrwxrwx 1 root root 11 2010-12-27 10:56 05f1c0af-2049-487a-bb45-77d0fc97c4bd -> http://www.cnblogs.com/sda10 lrwxrwxrwx 1 root root 10 2010-12-27 10:56 0a63aa06-8adb-47ea-9116-ed2ea0e28a5c -> http://www.cnblogs.com/sda8 lrwxrwxrwx 1 root root 11 2010-12-27 10:56 1cb39900-56e0-49cd-b6ca-0380bbd68d3c -> http://www.cnblogs.com/sda11 lrwxrwxrwx 1 root root 10 2010-12-27 10:56 3ba1745f-1726-484f-a557-761a72073c04 -> http://www.cnblogs.com/sda5 lrwxrwxrwx 1 root root 10 2010-12-27 10:56 92182c1f-033f-4c75-a727-00294285a8d9 -> http://www.cnblogs.com/sda7 lrwxrwxrwx 1 root root 10 2010-12-27 10:56 aed858e1-2a3f-4b4a-b13c-656e1b24554b -> http://www.cnblogs.com/sda6 lrwxrwxrwx 1 root root 10 2010-12-27 10:56 d9776b02-466b-4e20-8559-c34d1413df87 -> http://www.cnblogs.com/sda9
