### 提供了创建交换空间的方法 ###

### proc\_open(): fork failed errors[\#][Link 1] ###

If composer shows proc\_open() fork failed on some commands:

`PHP Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar`

This could be happening because the VPS runs out of memory and has no Swap space enabled.

free -m
    
    total used free shared buffers cached
    Mem: 2048 357 1690 0 0 237 -/+ buffers/cache: 119 1928 Swap: 0 0 0

To enable the swap you can use for example:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024 /sbin/mkswap /var/swap.1 /sbin/swapon /var/swap.1 下面是整个过程
