数字海洋上流星(mup)的内存问题

Question

我找不到与我的问题相关的现有帖子.在数字海洋Droplet上,mup设置很好,但是当我尝试部署时,我收到以下错误.有任何想法吗？谢谢!

root@ts:~/ts-deploy# mup deploy

Meteor Up: Production Quality Meteor Deployments

Building Started: /root/TS/
Bundling Error: code=137, error:

Figuring out the best package versions to use. This may take a moment.

-------------------STDERR-------------------

以下是日志.node -v表示我使用的是0.10.31.如何检查哪个脚本正在退出并显示错误？还有其他想法吗？谢谢!

在我回到DO Droplet的旧备份,并重新运行mup setup和mup deploy之后,我现在在命令行输出中得到这个

Building Started: /root/TS
Bundling Error: code=134, error:
-------------------STDOUT-------------------

这在日志中:

内存问题源于使用DigitalOcean的5美元Droplet.为了解决这个问题,我在服务器上添加了swap,如下面详细说明的那样.

使用dd命令创建并启用交换文件:

sudo dd if=/dev/zero of=/swapfile bs=1024 count=256k

"of =/swapfile"指定文件的名称.在这种情况下,名称是swapfile.

接下来通过创建linux交换区域来准备交换文件:

sudo mkswap /swapfile

结果显示:

Setting up swapspace version 1, size = 262140 KiB
no label, UUID=103c4545-5fc5-47f3-a8b3-dfbdb64fd7eb

通过激活交换文件完成:

sudo swapon /swapfile

然后,当您查看交换摘要时,您将能够看到新的交换文件.

swapon -s
Filename                Type        Size    Used    Priority
/swapfile                               file        262140  0   -1

此文件将在虚拟专用服务器上持续,直到计算机重新启动.您可以通过将交换添加到fstab文件来确保交换是永久性的.

打开文件:

sudo nano /etc/fstab

粘贴在以下行:

 /swapfile       none    swap    sw      0       0 

文件中的Swappiness应设置为10.跳过此步骤可能会导致性能不佳,而将其设置为10将导致交换充当紧急缓冲区,从而防止内存不足崩溃.

您可以使用以下命令执行此操作:

echo 10 | sudo tee /proc/sys/vm/swappiness
echo vm.swappiness = 10 | sudo tee -a /etc/sysctl.conf
To prevent the file from being world-readable, you should set up the correct permissions on the swap file:

sudo chown root:root /swapfile 
sudo chmod 0600 /swapfile
