Deploy TARO Documents to the 4 GB Memory Server

Jun 23rd, 2021 • Permalink

The official taro document build setting NODE_OPTIONS=--max-old-space-size=5120 in packages.json, but I would link to deploy a TARO documents to my 4 GB memory server, so here is how to.

Change NODE_OPTIONS settings

Change to NODE_OPTIONS=--max-old-space-size=2500 is reasonable in a 4GB memory server, but that's far from enough.

Enable the swap

sudo fallocate -l 1G /swapfile
# or sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
# To make it permanent
sudo echo '/swapfile swap swap defaults 0 0' >> /etc/fstab

Stop more services while building

sudo systemctl stop postgresql-12
sudo systemctl stop memcached
sudo systemctl stop nginx
sudo systemctl stop docker

It can be restart after reboot.

Install lib vips

The @docusaurus/core like 2.0.0-beta.1 require vips library, so need install vips at CentOS 7

Install lib vips

sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install yum-utils
sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum-config-manager --enable remi
sudo yum install vips vips-devel vips-tools

If in Ubuntu 20.04, just need install sudo apt-get install libvips-tools.
