Today I got an error in MySQL "InnoDB: Error: connot allocate bytes... you should increase swap"
I wanted to add more swap you can do it with a file like below or if you have space create a partition or logical volume (lv).
So, here's a simple step to add a swap space (Read more for details):
So, here's a simple step to add a swap space (Read more for details):
[1] create a new zeros file using dd command, since I'm adding more 1GB, the count parameter on dd should be 1024*1024=1048576 , here's the dd command (I named new swap file to /swapfile1):
[root@ns1 /]# dd if=/dev/zero of=/swapfile1 bs=1024 count=1048576[2] zeros file has been created, now we make it as swap file:
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB) copied, 45.5356 seconds, 23.6 MB/s
[root@ns1 /]# mkswap /swapfile1[3] change permissions
Setting up swapspace version 1, size = 1073737 kB
[root@ns1 /]# chmod 0600 /swapfile1[4] make it on!
[root@ns1 /]# swapon /swapfile1[5] check it using free
[root@ns1 /]# free

Yup, it's activated now.. you may add entry on your /etc/fstab so it will automounted when your server is rebooted, add this line
/swapfile1 swap swap defaults 0 0
That's it! Have fun with your server!
