Memory Allocation Error

时间:2021-10-01 21:15:37

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
Setting up swapspace version 1, size = 2047996 KiB
no label, UUID=385522ab-08b6-4941-9dc7-db5583fc78ac
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
