hint: use 'git pull' before pushing again.

是由于本地和远程仓库两者代码文件不同步，因此需要先pull，进行合并然后再进行push

一、先使用pull --rebase，拉取远程仓库文件同步到本地,--rebase参数将当前分支的更改重新应用到获取的最新提交上

[root@localhost newccdeploy]# git pull --rebase origin
Username for 'https://172.28.17.127': xxxxx
Password for 'https://xxxx@172.28.17.127': 
Successfully rebased and updated refs/heads/main.

二、再使用push，更新远程仓库

[root@localhost newccdeploy]# git push origin
