5 软件安装
5.1 NBU客户端软件安装
1) 在NBU Master Server，Media Server的/etc/hosts中添加MySQL服务器的主机名解析：

#mysql db

192.168.232.51 yhzd-db1

192.168.232.52 yhzd-db2
192.168.232.53 yhzd-db3 yhzd-

2) 在MySQL服务器的/etc/hosts中添加NBU Master Server，Media Server的主机名解析：

192.168.238.21 NBU-PRIMARY1
192.168.238.22 NBU-PRIMARY2
192.168.238.16 NBU-QUCHONG2
192.168.238.17 NBU-QUCHONG
192.168.238.23 NBUVIP-em1 NBUMASTER

3) 登陆NBU Master Server，进行客户端软件推送：

[root@NBU-PRIMARY1 RedHat2.6.18]# ./sftp_to_client yhzd-db3 root
Connecting to 192.168.232.53...
root@192.168.232.53's password:

sftp completed successfully.

The root user on 192.168.232.53 must now execute the command
"sh /tmp/bp.10261/client_config [-L]". The optional argument, "-L",
is used to avoid modification of the client's current bp.conf file.
[root@NBU-PRIMARY1 RedHat2.6.18]#

4) 推送完成后，登陆客户端yhzd-db3进行NBU客户端软件安装：

root@yhzd-db3 tmp]# cd bp.10261/
[root@yhzd-db3 bp.10261]# ls
bin_net.tar client_config openv
[root@yhzd-db3 bp.10261]# ./client_config

5) 等待客户端软件安装完成；
5.2 安装MEB插件
Netbackup通过Oracle提供的MEB（MySQL Enterprise Backup）对MySQL数据库进行备份，在MySQL服务器上需要安装MEB插件；
1) 下载MEB插件并上传到MySQL服务器上；
2) 安装MEB插件：

[root@yhzd-db3 tmp]# rpm -ivh meb-3.12.2-el6.x86_64.rpm
warning: meb-3.12.2-el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing... ########################################### [100%]
1:meb #### [100%]
[root@yhzd-db3 tmp]# rpm -qa | grep -i meb
meb-3.12.2-1.x86_64

6 备份配置
6.1 创建备份脚本
6.1.1 MySQL备份说明
1) 使用MEB备份MySQL数据库分为全备份和增量备份；
2) 全备份是一份完整的备份数据；
3) 增量备份通过参数：--incremental-base来控制此次增量备份依据什么时候的数据来进行：
history:backup， 依据上一次成功的备份中的lsn
dir: dir>， 依据上一次成功备份的目录中的meta data文件中的lsn

在这里我们通过dir: 来实现每次增量备份都使用上一次成功的全备份中的meta data文件的lsn进行增量，从而达到累计增量备份的效果；
4) 增量备份参数：--incremental-with-redo-log-only
此参数使得增量备份时通过MySQL的redo log来判断此次增量部分数据；由于redo要求log是循环使用的，因此使用此参数要求redo log的大小必须能容纳上次备份到此次备份之间的数据变化；
6.1.2 备份脚本
1) 在MySQL服务器上创建以下目录：

# mkdir -p /usr/openv/scripts/
# mkdir -p /usr/openv/scripts/logs/

2) 创建全备份脚本：

#!/bin/sh
