解决办法：
一般是内存不足导致进程被杀死。
没办法增大物理内存的话可以考虑扩容 swap 分区。
参考如下：
composer 安装或者更新时报错killed ，因为当前内存不足。
free -m mkdir -p /var/_swap_ cd /var/_swap_ #Here, 1M * 2000 ~= 2GB of swap memory dd if=/dev/zero of=swapfile bs=1M count=2000 mkswap swapfile swapon swapfile echo “/var/_swap_/swapfile none swap sw 0 0” >> /etc/fstab #cat /proc/meminfo free -m
