Linux开启Swap分区

创建要作为swap分区的文件:增加1GB大小的交换分区，则命令写法如下，其中的count等于想要的块的数量（bs*count=文件大小）。

$ dd if=/dev/zero of=/root/swapfile bs=1M count=1024

格式化为交换分区文件:

$ mkswap /root/swapfile #建立swap的文件系统

启用交换分区文件:

$ swapon /root/swapfile #启用swap文件

使系统开机时自启用，在文件/etc/fstab中添加一行：

/root/swapfile swap swap defaults 0 0
