CentOS 6에서 rpm 설치(wkhtmltopdf 설치 기준)

2020년 11월 30일부로 CentOS 6의 지원이 종료되었다. 그래서 yum으로 rpm을 설치시 다음과 같은 오류가 발생한다.

====================================================================

[root@localhost opt]# yum install wkhtmltox-0.12.6-1.centos6.x86_64.rpm 
Loaded plugins: fastestmirror

====================================================================

이를 해결하기위해 다음 명령어를 모두 실행한후 위 설치를 다시 실행하면 정상적으로 설치될것이다.(2021.02.15일 정상 작동)
