取代mysqldump的新工具mydumper

Posted 2020-08-21

下载地址：https://launchpadlibrarian.net/225370879/mydumper-0.9.1.tar.gz

# yum -y install glib2-devel mysql-devel zlib-devel pcre-devel cmake

# tar xf mydumper-0.9.1.tar.gz

# cd mydumper-0.9.1

# cmake .

# make && make install

解压的安装的mysql server 报错：

[[email protected] mydumper-0.9.1]# mydumper -h

mydumper: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

拷贝库到/lib64/下：

# cp /home/data/mysql-5.6.32/lib/libmysqlclient.so.18 /lib64/

备份性能比较：

# time mydumper -u root -p "123456"  -B zabbix -o /usr/local/src/bak/1/

real 0m2.733s

user 0m1.075s

sys 0m0.158s

# time /data/mysql-5.6.32/bin/mysqldump -u root -p"123456" -q --single-transaction -B zabbix > zabbix.sql

real 0m15.019s

user 0m1.495s

sys 0m0.271s

用myloader导入该XXDB数据库

# time myloader -u root -p 123456 -d /usr/local/src/bak/1/

导出 mydumper 要比mysqldump快一倍

导入 myloader 要比自带的mysql快一倍
