MYSQL数据库备份还原，并还原到最新状态(mysqldump,xtrabackup)
启用二进制日志文件
vim /etc/my.cnf 配置文件位置及文件名根据实际状况肯定
sql_log_bin=ON|OFF:是否记录二进制日志，默认为ON //在须要的时候设置为OFF
log_bin=/PATH/BIN_LOG_FILE:指定二进制日志文件位置; 一般单独存放到与数据库不一样的机器中 mysql
清理二进制日志文件
show master logs; 查看二进制日志文件列表
flush logs; 切换二进制日志文件(mysql命令),建立新的二进制日志
mysqladmin flush-logs 切换二进制日志文件(bash命令)
purge binary logs to 'mysqlbin.000005'; 删除除mysqlbin.000005日志以前的全部日志，保留mysqlbin.000005及之后的日志
reset master logs; 从新001开始记数二进制日志(老版本)。从MariaDB10.1.6开始支持TO #,指定从#开始记数 sql
一 彻底备份，并还原到最新状态(mysqldump)
前提条件：启用二进制日志，并单独存放。在mysql数据丢失时，能够还原最新备份到丢失时刻的数据
1 彻底备份 数据库
mysqldump -A --single-transaction --master-data=1 > /data/backup/all_mysql.sql
彻底备份数据库文件，并存放多份到安全的地方
2 修改数据库(在数据表中添加多条记录。模拟数据增长，但尚未备份时数据丢失的状况。能够经过二进制日志还到最新的数据) vim
mysql> insert TABLENAME(col_name,...)value(value,...)
3 数据库文件丢失 安全
rm -rf /data/mysql/*
测试效果，清空mysql数据目录，数据所有丢失，但开启了二进制日志，并单独存放在其余的硬盘中
4 中止mysql服务 bash
service mysqld stop
5 查看彻底备份时二进制日志备份的最后位置,实验时备份的最后位置为：CHANGE MASTER TO MASTER_LOG_FILE='mariadb.000001', MASTER_LOG_POS=8944;
经过less 命令查看最新的备份文件all_mysql.sql获取此信息 app
-- MySQL dump 10.16 Distrib 10.2.23-MariaDB, for Linux (x86_64) -- -- Host: localhost Database: -- ------------------------------------------------------ -- Server version 10.2.23-MariaDB-log /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; /*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */; /*!40103 SET TIME_ZONE='+00:00' */; /*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */; /*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */; /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */; /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */; -- -- Position to start replication or point-in-time recovery from -- -- CHANGE MASTER TO MASTER_LOG_FILE='mariadb.000001', MASTER_LOG_POS=8944; -- -- GTID to start replication from -- /data/backup/all_2019-05-06.sql . .
重启mysql服务：less
service mysqld restart
登陆mysql :socket
mysql -uroot -p
临时关闭二进制日志,还原彻底备份：ide
mysql> set sql_log_bin=off; mysql> soruce /data/backup/all_mysql.sql
6 还原没有备份的新数据
新开一个终端：用mysqlbinlog工具导出存放在二进制日志中没有备份的新记录，开始位置为第4步中查询到的位置(实验时为8944)
mysqlbinlog --start-position=8944 /data/bin/mariadb.000001 > /data/backup/inc.sql
在原终端中继续还原
mysql> source /data/backup/inc.sql
到此已经还原所有数据
二 xtrabackup(2.4.13)
新版xtrabackup彻底备份及还原(MariaDB5.5.60)
安装xtrabackup ,下载的rpm包，由于有依赖，因此用yum安装
[root@Centos7 ~]#yum install percona-xtrabackup-24-2.4.13-1.el7.x86_64.rpm -y

再添加一条记录，测试第二次增量备份
xtrabackup --backup --target-dir=/data/inc2 --incremenal-basedir=/data/inc1
- 将备份数据传送到目标主机
scp -r /data/* 192.168.37.17:/data/
在目标主机还原数据
- 预准备彻底备份 --apply-log-only 阻止回滚未完成的事务，最后一次合并不用添加 xtrabackup --prepare --apply-log-only --target-dir=/data/backup 合并第一次增量备份到彻底备份 --incremental-dir 增量备份的目录 xtrabackup --prepare --apply-log-only --target-dir=/data/backup --incremental-dir=/data/inc1合并第二次增量备份到彻底备份，由于实验时第二次增量为最后增量，全部不用阻止回滚选项 xtrabackup --prepare --target-dir=/data/backup --incremental-dir=/data/inc2 复制到数据库目录，数据库目录必须为空，mysql服务不能启动 xtrabackup --copy-back --target-dir=/data/backup 还原属性：chown -R mysql.mysql /var/lib/mysql 启动服务，能够查询到增长的新数据
