Proc_open (): fork failed-Cannot allocate memory after installing composer

1. Problem description:

"proc_open (): fork failed-Cannot allocate memory" appears when the linux server deploys the yii project using composer

That is, the prompt "out of memory", we can solve this problem by creating a swap partition.

two。 Solution:

Run free-m first to see how much space it is.

Run the following three commands in turn in the command line environment

Dd if=/dev/zero of=/var/swap.1 bs=1M count=1024mkswap / var/swap.1swapon / var/swap.1

For example: [the following is the result of my running on the server]

Dd if=/dev/zero of=/var/swap.1 bs=1M count=1024 / / the first instruction 10240records in / / this is the returned content 1024400records out / / this is the returned content 1073741824 bytes (1.1GB) copied, 10.0607 s, 107MB/s / / this is the returned content mkswap / var/swap.1 / / the second instruction Setting up swapspace version 1, size = 1048572 KiB / / this is the returned content no label UUID=f6280c41-21b4-4039-bc3e-c26284b47b0c / / this is the returned content swapon / var/swap.1 / / the third instruction swapon: / var/swap.1: insecure permissions 0644, 0600 suggested. / / this is the returned content

Explanation:

Dd copies a 1G file from / dev/zero device / var/swap.1mkswap format / var/swap.1swapon hangs the swap partition to the file system and type free-m to view memory usage information

Finally, the composer update is executed again and it is successful.
