5) commercial 인증서 Zimbra 복사
mkdir /opt/zimbra/ssl/letsencrypt
cp /etc/letsencrypt/live/mail.ycis.co.kr/* /opt/zimbra/ssl/letscnrypt/
chown zimbra.zimbra /opt/zimbra/ssl/letsencrypt/*
ls -al /opt/zimbra/ssl/letsencrypt/
mkdir /opt/zimbra/ssl/letsencrypt
cp /etc/letsencrypt/live/mail.ycis.co.kr/* /opt/zimbra/ssl/letscnrypt/
chown zimbra.zimbra /opt/zimbra/ssl/letsencrypt/*
ls -al /opt/zimbra/ssl/letsencrypt/
6) private key 를 Zimbra SSL 경로로 복사, ssl 배포 (zimbra 유저로)
su – zimbra
cd /opt/zimbra/ssl/letsencrypt
zmcertmgr verifycrt comm privkey.pem cert.pem chain.pem
~
Valid certificate chain: cert.pem: OK
~
cp /opt/zimbra/ssl/letsencrypt/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.key
/opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem chain.pem
~ ssl 배포 ~
zmcontrol restart
exit
6. Comodo SSL 설치 (방법2. 상용 SSL)
* 서버에서 csr 키를 생성하지 않고 자동 생성값으로 Comodo SSL 신청하여 사용하는 방법 입니다. *
1) 4개의 인증서 서버에 다운로드
AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt
mail_orlinux_com.crt
mail_orlinux_com_SHA256WITHRSA.key
2) CA 인증서 하나로 합치기
cat AddTrustExternalCARoot.crt COMODORSAAddTrustCA.crt COMODORSADomainValidationSecureServerCA.crt > /tmp/commercial_ca.crt
cp mail_orlinux_com_SHA256WITHRSA.key /opt/zimbra/ssl/zimbra/commercial/commercial.key
3) SSL 인증서 복사
cp mail_orlinux_com.crt /tmp/commercial.crt
4) 인증서 점검
su – zimbra
/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key /tmp/commercial.crt /tmp/commercial_ca.crt
~ 생략 ~
Valid Certificate: /tmp/commercial.crt: OK
5) 인증서 배포
su – zimbra
/opt/zimbra/bin/zmcertmgr deploycrt comm /tmp/commercial.crt /tmp/commercial_ca.crt
6) zimbra 재시작
zmcontrol restart
7. 서비스 점검
