XtraBackup enables MySQL to redo master-slave replication without stopping services You can use mysqldump to implement MySQL master-slave synchronization without stopping services, but this efficiency is relatively low. XtraBackup is used to achieve this, which is more efficient! Xtrabackup installation:Yum-y install perl-devel libaio-devel perl-Time-HiRes perl-DBD-MySQLRpm-ivh percona-xtrabackup-2.2.12-1.el6.x86_64.rpm Install libenv:Wget ftp://rpmfind.net/linux/atrpms/el6-x86_64/atrpms/stable/

the data file is copied, the log replication thread ends. In this way, the data copies at different time points and the transaction logs after the backup start are obtained. After completing the preceding steps, you can use the InnoDB crash recovery code to execute the transaction log (redo log) to achieve data consistency. There are two backup processes: Backup, backup phase, tracking transaction logs and copying data files (physical backup ). Preparing: replays transaction logs, so that all d

JDK provides very convenient base64encoder and base64decoder, which can be used to conveniently complete base64-based encoding and decoding. The following are two small functions compiled by myself for base64 encoding and decoding: // Encode s with base64Public static string getbase64 (string s ){If (S = NULL) return NULL;Return (new sun.
