mysql을 설치하자.. 요건 좀 어려울라나~ 우선 고고~~~

그런데 이상하다. 아래처럼 설치하니 뭔가 이상함  항상 쓰던 mysql 접속에서

...그래서 우선 삭제 요점은 맨밑에

/*---------------------------------------------------------------------------------------*/

[root@localhost ~]# yum -y install mysql

mariadb?? 이게 뭐지.. 검색해보니 centos7에서 mysql은 다운받아서 써야됨 젠장

그럼 다운받아주지..아래 그림설명해놔야징..

/*---------------------------------------------------------------------------------------*/

/*---------------------------------------------------------------------------------------*/

mysql 홈페이지 다운로드->yum  들어가서 centos7이니까 linux7 다운로드 하자

그담에 받은 패키지를 올려볼까~~ 경로는 맘대로 /usr/etc 요기에 넣었당. 

/*---------------------------------------------------------------------------------------*/

/*---------------------------------------------------------------------------------------*/

자 올렸다.. 올리는 방법은 툴을 이용하는게 좋을듯. 하는김에 툴도 올려놓자 sshclient 아주 자주 사용하니까

그럼 다시 설치 시작

/*---------------------------------------------------------------------------------------*/

여까지 했으면 재부팅 해보는것도 나쁘지 않을듯. 정말 작동되는지도 확인해보고..

그럼 이제 작동하는지 확인해 볼까~~! 시작..

너무 길어졌다. query문은 고만~

요점정리 하자.. 또 필요하거나 주석달일 생기면 계속업데이트 해놔야징... 

/*---------------------------------------------------------------------------------------*/

 1.  mysql.com에서 패키지 다운 받아서 /usr/etc에 저장
 2. [root@localhost ~]# yum -y install /usr/etc/mysql-community-release-el7-5.noarch.rpm

 3. [root@localhost ~]# yum -y install mysql-community-server
 4. [root@localhost ~]# systemctl start mysqld  <-(요건 뭐 mysql 실행하는거야) 

 5. [root@localhost ~]# systemctl enable mysqld <-(요것도 뭐 당연히 해야 재부팅시 자동으로 올라온다)

 6. [root@localhost ~]# mysql -u root -p mysql

 7. mysql> update user set password=password('알아서넣자') where user='root';

 8. mysql> flush privileges;

 9. mysql> exit
10.[root@localhost ~]#
