Mysql veri dizinini docker kabında nasıl taşıyabilirim?

Question

Anasistem veri hacmine sahip mysql-5.5 çalışan bir docker kabı var. Kapsayıcımı mysql-5.6'ya yükseltiyorum. Aynı ana bilgisayar hacmine sahip yeni bir kap başlıyorum. MySQL, mysql.user tablosunun çökmesi nedeniyle kapsayıcıda çöküyordu.

[ERROR] Fatal error: Can't open and lock privilege tables: 
Incorrect key file for table 'user'; try to repair it 
160523 12:04:13 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended 

bunu düzeltmeye aşağıdaki çalıştı:

root@container# mysqld --skip-grant-tables; 
root@container# mysql -uroot -ppassword

Answer 1

Sana mysql başlamadan önce mysql-upgrade çalıştırmak için dockerfile değiştirmeniz gerekir inanıyoruz. Sağladığınız referanslarda belirtildiği gibi onarmanız gerekebilir. Sadece bir kez çalıştırmanız gerekir, ardından dockerfile'dan kaldırabilirsiniz. (Ben veritabanı gerçekte ana dosya sisteminde depolanan ve docker monte edilir varsayalım.)

Answer 2

Sen 5.5 görüntü kullanılarak MySQL başlar ve

docker run --rm --link mysqld mysql:5.5 \ 
     mysqldump -h mysqld --all-databases > /your/host/machine/ 

karşı Mysqldump çalıştırmak Sonra kullanarak yeni bir kapsayıcı başlayabileceğini 5.6 görüntü ve komut kullanabilirsiniz sonrasında gerçekleşmektedir ne SQL dökümü

docker run -v /data/your_dump.sql:/docker-entrypoint-initdb.d/dump.sql mysql:5.6
