$ ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "dreamtails@pixnet.cc"

Command:
$ git clone https://192.168.100.100/dreamtails/Dreamtails_Project.git

Error Message：
fatal: unable to access 'https://192.168.100.100/dreamtails/Dreamtails_Project.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

How to Resolve?

[For Git]

$ git config --global http.sslVerify false

[For Linux]

$ export GIT_SSL_NO_VERIFY=1

[For Windows]

$ set GIT_SSL_NO_VERIFY 1

使用Crontab去定時備份GitLab的資料到遠端的NFS Server (192.168.100.100:/backup/gitlab)

1. Check crond service.
# systemctl list-unit-files

2. 若crond.service是disabled，請將它enable，這樣OS啟動後才會自動執行
# systemctl enable crond.service

3. 手動啟動crond service
# systemctl start crond.service

4. 編輯crontab設定
# crontab -e

環境：
    OS: CentOS 7.6
    原本的GitLab IP: 1.1.1.1
    新的GitLab IP: 2.2.2.2
