1) 키페어 생성
~/.ssh/id_rsa # private key
~/.ssh/id.rsa.pub # public key ( 다른 서버에 복사해야할 파일)
2) pub 키를 접속할 호스트로 복사
scp ~/.ssh/id_rsa remoteuser@remotehost:id_rsa.tmp
3) ssh 접속후 키 복사 (기존 파일에 붙여 넣기 )
cat id_rsa.tmp >> ~/.ssh/authorized_keys
4) 이후 패스워드 없이 접속
ssh remoteuser@remotehost
1) Install brew
home page: https://brew.sh/
2 ) Install python3
$> brew install python3
3) Install virtualenv
$> pip3 install virtualenv
4) check installed python version
ls -l /usr/local/bin/python*
5) make Local Env
$> python3 -m virtualenv venv310 --python=/usr/local/bin/python3.10
// venv310 : directory which contains python3.10 data
// --python={installed path} : source path which is selected python version
1) define function in app level
function. custom_event (key, event) {
// this is custom function
console.log ("call custom function ") ;
}
2) passing custom function to child by property
when click item , item calls internalClick
custom_event function is called by name "customFunction" in internalClick function
// in app.js
function. custom_event (key, event) {
// this is custom function
console.log ("call custom function ") ;
}
<BoardList customFunction= { this.props.custom_event } />
// in BoardList.js
// some loop ...
<BoardRow keyField={ this.props.keyField} customFunction = { this.props.customFunction} />
// in BoardRow.js
<BoardItem keyField={ this.props.keyField} customFunction = { this.props.customFunction} />
// in BoardItem.js
internalClick = (e) => {
console.log ( "click item ") ;
this.props.customFunction(this.props.keyField , e) ;
}
render() {
return (<button onClick = { this.internalClick } > click </button>)
}
