Why 80% of the code can not do farming architect? >>>  

MySQL database backup, you need to take into account the data engine, data size, whether the lock table, whether online, time-consuming backup and other factors. For different data engine back up differently, some backup methods are not compatible with other engines. Recommended Percona xtrabackup tool to back up MySQL database. Percona xtrabackup related content can be found in: http: //www.ttlsa.com/ s = xtrabackup? . Here to tell you at mylvmbackup backup tool, as the name implies, can be seen from the name is for the use of LVM disk backup tool mysql database. The basic principle is to first flush tables with read lock, established lvm snapshots, unlock table, copy files, delete lvm snapshot. One. Prerequisites perl-5 perl-DBD perl- DBI perl-Config-IniFiles // reads the program global configuration file perl-TimeDate perl-DBD-MySQL II. Download and install

# wget http://lenzg.net/mylvmbackup/mylvmbackup-0.13.tar.gz
# tar zxvf mylvmbackup-0.13.tar.gz

three. Configuration [Mysql] // user defined database connection = root password = password host = localhost port = 3306 socket = / tmp / mysql.sock mycnf = / etc / my.cnf # [lvm] // lvm defined parameters, refer to the actual environmental vgname = VolGroup00 lvname = lvmydata backuplv = // define the snapshot volume name, the default is _sanpshot # lvsize must be able to cope with differences lvsize = 5G // define snapshot size # [fs] xfs = 0 mountdir = / var / tmp / mylvmbackup / mnt / // mount directory. The default backupdir = / var / tmp / mylvmbackup / backup / // backup directory can be backed up to a remote host. The default relpath = // logical volume associated with the mysql data directory. Default is null # [tools] // use the command definition lvcreate = / usr / sbin / lvcreate lvremove = / usr / sbin / lvremove lvs = / usr / sbin / lvs mount = / bin / mount tar = / bin / tar compress = / bin / gzip # alternative tar backup compression tools # compress = lzma # compress = bzip2 # or (for no compression): four. practice
