我正在尝试使用innobackupex从远程计算机进行备份.

./innobackupex --host=<mysql_server> --user=<username> <backup_dir>.

它失败了,因为它无法在服务器中找到目录.

 (Errcode: 2 - No such file or directory)

我假设它正在本地机器中搜索目录.请告诉我们如何远程运行备份？

恢复备份后mysql服务器无法启动。

quit without updating PID file

备份命令行

innobackupex --user=root --password=pass --databases="the_database" --stream=tar ./ 2> /var/log/innobackupex.log | gzip -c -1 > /var/bak/backup.tar.gz

恢复命令行

tar -izxf /var/bak/db/2013-11-16-2300_mysql.tar.gz -C /var/bak/db_import
innobackupex --defaults-file=/var/ini/my.cnf --use-memory=1G --apply-log /var/bak/db_import
service mysql stop
mv /var/lib/mysql /var/lib/mysql-old
mkdir /var/lib/mysql
innobackupex --defaults-file=/var/ini/my.cnf --copy-back /var/bak/db_import
chown -R mysql:mysql /var/lib/mysql
service mysql start
