1.创建分区
Command (m for help): n Command action l logical (5 or over) p primary partition (1-4) l First cylinder (641-1566, default 641): Using default value 641 Last cylinder or +size or +sizeM or +sizeK (641-890, default 890): Using default value 890
Command (m for help): p
Disk /dev/sda: 12.8 GB, 12884901888 bytes 255 heads, 63 sectors/track, 1566 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sda1 * 1 6 48163+ 83 Linux /dev/sda2 7 515 4088542+ 83 Linux /dev/sda3 516 1566 8442157+ 5 Extended /dev/sda5 891 1015 1004031 83 Linux/dev/sda6 1016 1566 4425876 83 Linux /dev/sda7 516 640 1004031 83 Linux /dev/sda8 641 890 2008093+ 83 Linux
2.指定分区类型为linux swap，这里的/dev/sda5就是我们要做swap的分区。Command (m for help): t Partition number (1-8): 5 Hex code (type L to list codes): 82
Command (m for help): p
Disk /dev/sda: 12.8 GB, 12884901888 bytes 255 heads, 63 sectors/track, 1566 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/sda1 * 1 6 48163+ 83 Linux /dev/sda2 7 515 4088542+ 83 Linux /dev/sda3 516 1566 8442157+ 5 Extended /dev/sda5 516 640 1004031 82 Linux swap /dev/sda6 641 890 2008093+ 83 Linux /dev/sda7 891 1015 1004031 83 Linux /dev/sda8 1016 1566 4425876 83 Linux 3.用mkswap命令设置交换分区 [root@libydwei /]# mkswap /dev/sda5 Setting up swapspace version 1, size = 1028120 kB
4.swapon激活swap分区
[root@libydwei /]# swapon /dev/sda5
5.为了能够在系统启动是自动挂载，我们需编辑/etc/fstab配置文件。
在文件末尾处增加：
/dev/sda5 swap swap defaults 0 0
