=> Appending bash_completion source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
[root@discord-bot-test ~]#



# bash profile 적용
[root@discord-bot-test ~]# source .bash_prrofile

 

 

(1) node.js 설치

 

> 버전을 지정하여 설치 (본인의 경우 Local에 12.15버전이 설치되어있어서 동일하게 설치함)

[root@discord-bot-test ~]# nvm install v12.15.0

[root@discord-bot-test ~]#

 

> 설치 후 버전 확인

[root@discord-bot-test ~]# node -v
v12.15.0
[root@discord-bot-test ~]# npm -v
6.13.4
[root@discord-bot-test ~]#

 

(2) 외부 접근을 위한 Port 허용

 

> Nodejs에서 사용할 포트를 추가하기 위함.

기본적을 3000번 포트를 사용하며 본인이 앞으로 사용할 포트를 추가하면 됨.

 

시작에 앞서 현재 허용중인 포트 상태 확인

[root@discord-bot-test ~]# iptables -L -v

Chain INPUT (policy ACCEPT 117 packets, 8050 bytes)
 pkts bytes target     prot opt in     out     source               destination

    0     0 ACCEPT     tcp  --  any    any     anywhere             anywhere             tcp dpt:rfb

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination


Chain OUTPUT (policy ACCEPT 90 packets, 21052 bytes)
 pkts bytes target     prot opt in     out     source               destination
