A CA file has been bootstrapped using certificates from the system

and run
  /usr/local/opt/openssl@1.1/bin/c_rehash

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.

If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

설치후 익명상태로 mysql 명령을 사용하여 쓸 수 있지만, 보안에 취약합니다.

완전히 삭제후 다시 설치했기 때문에 다음과 같이 실행 됩니다.

$ brew services start mysql

MySQL 서비스를 시작하고 접속해 봅니다. 현재는 root 사용자의 비밀번호가 없는 상태입니다.
이제 MySQL 설정하기 위해서

"mysql_secure_installation" 명령어를 입력해주세요.

레퍼런스에 나온 설명보면서 설정

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No: no

패스워드를 입력하라고 하니 입력합니다.

New password:

Re-enter new password:
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.


Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.

"Remove anonymous users? (Press y|Y for Yes. any other key for No)"

사용자 설정을 묻는 질문입니다.

Yes 또는 No를 입력해주세요.

Yes - 접속하는 경우 "mysql -uroot"처럼 -u 옵션 필요

No - 접속하는 경우 "mysql"처럼 -u 옵션 불필요

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

"Remove test database and access to it? (Press y|Y for Yes, any other key for No)"

Test 데이터베이스를 설정하는 질문입니다.

Yes - Test 데이터베이스 제거

No - Test 데이터베이스 유지

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!

"Reload privilege tables now? (Press y|Y for Yes, any other key for No)"

변경된 권한을 테이블에 적용하는 설정에 대한 질문입니다.

Yes - 적용시킨다.

No - 적용시키지 않는다.

*저는 "Yes"로 설정하였습니다.

(해당 질문은 무조건 "Yes" 하시기 바랍니다.)

일단은 빠르게 설치합니다.

터미널을 켜서
mysql -u root -p 명령어를 입력합니다.
위에 root비밀번호를 입력한 비밀번호로 접속할 수 있습니다.

mysql 설정파일을 수정하기로 했음.
리눅스에 vi ( 에디터 설치 )
sudo apt-get install vim 수퍼유저라면 #이 붙어있다면 sudo 빼면됩니다.
