Digital Ocean 上的流星 (mup) 内存问题

Question

我找不到与我的问题相关的现有帖子。在 Digital Ocean Droplet 上，mup 设置正常，但是当我尝试部署时，出现以下错误。有任何想法吗？谢谢！

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

Meteor Up: Production Quality Meteor Deployments

Building Started: /root/TS/

以下是日志。 node -v 表示我使用的是 0.10.31。如何检查哪个脚本因错误而退出？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 后，我现在在命令行输出中得到了这个

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

这在日志中：

Answer 1

内存问题源于使用 DigitalOcean 的 5 美元 Droplet。为了解决这个问题，我added swap到服务器，下面详细解释。

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”指定文件名。在这种情况下，名称是交换文件。

接下来通过创建一个 linux 交换区来准备交换文件：

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

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存在，直到机器重新启动。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

粘贴到以下行：

 /swapfile       none    swap    sw      0       0 

文件中的 Swappiness 应设置为 10。跳过这一步可能会导致性能下降，而将其设置为 10 会导致 swap 充当紧急缓冲区，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

Answer 2

只有将交换空间增加到 1gb 才对我有用：

Make all swap off
sudo swapoff -a

Resize the swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=1024

Make swapfile usable
sudo mkswap /swapfile

Make swapon again
sudo swapon /swapfile
