Memory Allocation Error

Memory allocation error happened when I tried to install MySQL 5.7.13 in my server, which has 2G memory.

Obviously, I know that there is not enough memory for me to install it.

But I figure out a sollution that I can make a swap for my server so that I can install it. Here are the steps as

following:

shell#  free -m

                  total       used       free     shared    buffers     cached

Mem:          2002        179       1822          0          6         87

-/+ buffers/cache:         85       1916

Swap:            0          0          0

shell# touch /opt/swap

shell# dd if=/dev/zero of=/opt/swap bs=1024 count=2048000

2048000+0 records in

2048000+0 records out

2097152000 bytes (2.1 GB) copied, 41.2271 s, 50.9 MB/s

shell# mkswap /opt/swap

shell# swapon /opt/swap

shell# free -m

                  total       used       free     shared    buffers     cached

Mem:          2002       1930         71          0          1       1793

-/+ buffers/cache:        135       1866

Swap:         1999          0       1999

If I want close swap, I can execute the commands:

shell# swapoff /opt/swap

shell# rm -f /opt/swap
