Bash, 명령은 기능으로 작동하지 않지만 수동은 작동합니다.

원격 컴퓨터의 mysql 덤프를 로컬 파일로 저장해야 하므로 ssh원격 컴퓨터에 연결하여 mysqldump원격 컴퓨터에서 스크립트를 실행하고 로컬 파일에 저장합니다.

내가 달릴 때

./export-db.sh ssc

그것은 나에게 그것을 보여주었습니다.

hosek@osw-backup:~/sofimon$ ./export-db.sh ssc
mkdir -p /mnt/export/ssc-osw-web
ssh -n sofimon@ssc-osw-web sudo mysqldump -uroot -pPASSWORD --max_allowed_packet=2147483648 --host=localhost --quote-names --ignore-table=mysql.event --opt --all-databases > /mnt/export/ssc-osw-web/20200221-110536-ssc-osw-web.mysqldump
20200221-110536|sofimon|export-db.sh|create export folder ssc-osw-web|true.
bash: /mnt/export/ssc-osw-web/20200221-110536-ssc-osw-web.mysqldump: No such file or directory
20200221-110538|sofimon|export-db.sh|dump database from ssc-osw-web|false!

그래서 command_mkdir괜찮지만 command_ssh작동하지 않습니다.

왜 잘못됐나요 No such file or directory?

$command_ssh터미널에서 수동으로 명령을 실행 하면 제대로 작동합니다.

ssh -n sofimon@ssc-osw-web sudo mysqldump -uroot -pPASSWORD --max_allowed_packet=2147483648 --host=localhost --quote-names --ignore-table=mysql.event --opt --all-databases > /mnt/export/ssc-osw-web/20200221-110536-ssc-osw-web.mysqldump

이 결과를 얻으려면 스크립트를 수정해 보십시오 echo $command_ssh.

ssh -n sofimon@ssc-osw-web "sudo mysqldump -uroot -pPASSWORD --max_allowed_packet=2147483648 --host=localhost --quote-names --ignore-table=mysql.event --opt --all-databases" > /mnt/export/ssc-osw-web/20200221-110536-ssc-osw-web.mysqldump

같은 오류입니다.

감사해요.

그러나 이것은 이것을 반환합니다.
