Error

1. 3306 port 개방

   
   vsCode에서도 동일한 오류 발생.

   Solution

   https://myjamong.tistory.com/7

   • 모든 포트 개방하기

     jsx language-javascript

     sudo iptables -F

   • • 필자는 먹히지 않았었음. 그래서 아래의 코드를 작성함.
     jsx language-javascript

     $ sudo firewall-cmd --zone=public --add-port=3306/tcp --permanent
     $ sudo firewall-cmd --reload
     $ sudo firewall-cmd --list-ports

   • 오픈중인 port 목록이 나옴. 아래 이미지처럼 나오면 해결.

     

   • 이미지는 없지만 다시 연결하니 연결이 잘 됨.

2. Current charset is UTF-8. If password has been set using other charset, consider using option 'passwordCharacterEncoding'] with root cause

• 이제 연결해서 localhost:80/test 에 연동된 데이터가 뜨나 싶었는데 해당 오류가 발생.
• 내일 해당 문제에 대해 고찰해 보고 해결하려고 함.
