ssh 비밀번호 사용하지 않기

client에서 할일

ssh-keygen -t rsa

1	ssh-keygen -t rsa

~/.ssh/id_rsa.pub 공개키 생성되면 접속할 서버에 ./ssh/authorized_keys 파일 안에 복사 해 넣는다.

ubuntu sudo 암호 사용하지 않게

관리자 권한으로 /etc/sudoers.d/init-users 파일 생성하여 다음과 같이 작성

# User rules for id
id ALL=(ALL) NOPASSWD:ALL

1 2	# User rules for id id ALL=(ALL) NOPASSWD:ALL

EF 내에 ForeignKey 구성에 따른 스키마 생성

ICollection 사용

public					ICollection<Student>		m_listLandSiteDataText		{ get; set; }

protected override void Up(MigrationBuilder migrationBuilder)
{
	migrationBuilder.AddColumn<int>(
		name: "CourseId",
		table: "Students",
		nullable: true);

	migrationBuilder.CreateIndex(
		name: "IX_Students_CourseId",
		table: "Students",
		column: "CourseId");

	migrationBuilder.AddForeignKey(
		name: "FK_Students_Courses_CourseId",
		table: "Students",
		column: "CourseId",
		principalTable: "Courses",
		principalColumn: "CourseId",
		onDelete: ReferentialAction.Restrict);
}

public ICollection<Student> m_listLandSiteDataText { get; set; }

protected override void Up(MigrationBuilder migrationBuilder)

{

migrationBuilder.AddColumn<int>(

table: "Students",

nullable: true);

migrationBuilder.CreateIndex(

table: "Students",

column: "CourseId");

migrationBuilder.AddForeignKey(

table: "Students",

column: "CourseId",

principalTable: "Courses",

principalColumn: "CourseId",

onDelete: ReferentialAction.Restrict);

}

Index와 ForeignKey 없이 생성

[ForeignKey("Course")]
public					int							CourseId					{ get; set; }

[ForeignKey("CourseId")]
public					int							CourseId					{ get; set; }

protected override void Up(MigrationBuilder migrationBuilder)
{
	migrationBuilder.AddColumn<int>(
		name: "CourseId",
		table: "Students",
		nullable: false,
		defaultValue: 0);
}

[ForeignKey("Course")]

public int CourseId { get; set; }

[ForeignKey("CourseId")]

public int CourseId { get; set; }

protected override void Up(MigrationBuilder migrationBuilder)

{

migrationBuilder.AddColumn<int>(

table: "Students",

nullable: false,

defaultValue: 0);

}

virtual 사용시

public					int							CourseId					{ get; set; }
[ForeignKey("CourseId")]
public	virtual			Course						m_mvLandSiteDataImage		{ get; set; }

protected override void Up(MigrationBuilder migrationBuilder)
{
	migrationBuilder.AddColumn<int>(
		name: "CourseId",
		table: "Students",
		nullable: false,
		defaultValue: 0);

	migrationBuilder.CreateIndex(
		name: "IX_Students_CourseId",
		table: "Students",
		column: "CourseId");

	migrationBuilder.AddForeignKey(
		name: "FK_Students_Courses_CourseId",
		table: "Students",
		column: "CourseId",
		principalTable: "Courses",
		principalColumn: "CourseId",
		onDelete: ReferentialAction.Cascade);
}

public int CourseId { get; set; }

[ForeignKey("CourseId")]

public virtual Course m_mvLandSiteDataImage { get; set; }

protected override void Up(MigrationBuilder migrationBuilder)

{

migrationBuilder.AddColumn<int>(

table: "Students",

nullable: false,

migrationBuilder.CreateIndex(

table: "Students",

migrationBuilder.AddForeignKey(
