解决方法，建立swap
# dd if=/dev/zero of=/root/myswapfile bs=1M count=1024 1024+0 records in 1024+0 records out # ls -l /root/myswapfile -rw-r--r-- 1 root root 1073741824 Aug 14 23:47 /root/myswapfile
# chmod 600 /root/myswapfile
# mkswap /root/myswapfile Setting up swapspace version 1, size = 1073737 kB
# swapon /root/myswapfile
# cat /etc/fstab # 添加下面这句 /root/myswapfile swap swap defaults 0 0
