###Now we need install nodejs via npm as the repo package is too old.这一步网络差的话，隔一段时间尝试一下
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
source ~/.bash_profile
nvm list-remote
nvm install v14.18.1 # as of this writing check the result of the list-remote to see all choices
### start redis and set it to start on reboot
systemctl start redis
systemctl enable redis
### clone the NodeBB repository，也可以直接从https://github.com/NodeBB/NodeBB下载对应版本的zip包，到本地解压
cd /export/nodebb
git clone -b v1.18.x https://github.com/NodeBB/NodeBB nodebb
cd nodebb
###Initiate the setup script by running the app with the setup flag:
[nodebb@oracledb nodebb]$ ./nodebb setup
