innobackupex增量备份测试

1、全备
/opt/mysql/product/5.5/bin/innobackupex –defaults-file=/etc/my.cnf –no-timestamp –socket=/var/run/mysqld/mysqld.sock –user=root –password=passw0rd /opt/mysql/mysql_bak/full
2、修改库中数据
mysql> create database fei;
Query OK, 1 row affected (0.03 sec)
mysql> use fei;
Database changed
mysql> create table t_1 as select * from information_schema.tables;
Query OK, 83 rows affected (0.20 sec)
Records: 83 Duplicates: 0 Warnings: 0
mysql> create table t_2 as select * from information_schema.tables;
Query OK, 84 rows affected (0.03 sec)
Records: 84 Duplicates: 0 Warnings: 0
mysql> create table t_3 as select * from information_schema.tables;
Query OK, 85 rows affected (0.04 sec)
Records: 85 Duplicates: 0 Warnings: 0

3、增量备份
/opt/mysql/product/5.5/bin/innobackupex –defaults-file=/etc/my.cnf –no-timestamp –socket=/var/run/mysqld/mysqld.sock –user=root –password=passw0rd –incremental –incremental-basedir=/opt/mysql/mysql_bak/full /opt/mysql/mysql_bak/inc

4、恢复全备
/opt/mysql/product/5.5/bin/innobackupex /opt/mysql/mysql_bak/full –apply-log

5、恢复增量备份
/opt/mysql/product/5.5/bin/innobackupex /opt/mysql/mysql_bak/full –incremental –incremental-dir=/opt/mysql/mysql_bak/inc –apply-log

6、还原数据库到默认目录
/opt/mysql/product/5.5/bin/innobackupex –defaults-file=/etc/my.cnf /opt/mysql/mysql_bak/full/ –copy-back

7、启动数据库测试
结论为:所有新创建的对象都没恢复成功
后来创建的库和表结构都不存在,在执行增量恢复的时候,有如下错误提示:
110719 11:49:57 InnoDB: Operating system error number 2 in a file operation.
InnoDB: The error means the system cannot find the path specified.
xtrabackup: error: cannot open /opt/mysql/mysql_bak/full/fei/t_2.ibd
xtrabackup: Error: xtrabackup_apply_delta() failed.
xtrabackup: page size for /opt/mysql/mysql_bak/inc/fei/t_3.ibd.delta is 16384 bytes
110719 11:49:57 InnoDB: Operating system error number 2 in a file operation.
InnoDB: The error means the system cannot find the path specified.
xtrabackup: error: cannot open /opt/mysql/mysql_bak/full/fei/t_3.ibd
xtrabackup: Error: xtrabackup_apply_delta() failed.
xtrabackup: page size for /opt/mysql/mysql_bak/inc/fei/t_1.ibd.delta is 16384 bytes
110719 11:49:57 InnoDB: Operating system error number 2 in a file operation.
InnoDB: The error means the system cannot find the path specified.
xtrabackup: error: cannot open /opt/mysql/mysql_bak/full/fei/t_1.ibd
xtrabackup: Error: xtrabackup_apply_delta() failed.
fei.*对象是在全备之后创建的,全备份集中并不存在,因此应用增量时就报了错,此时如果原始数据文件已经损坏,那么fei.*的数据就无法恢复了,因为缺少了其数据文件。innobackupex增量备份和恢复功能还不完善,有新增对象时会出错

mysql-cluster 7.x安装(linux)

一、整体规划
192.168.11.10(ndb)
192.168.11.11(ndb)
192.168.11.12(mgm)
192.168.11.13(sql)
192.168.11.14(sql)

二、安装mysql-cluster软件(root)
所有节点相同操作,如果没有mysql用户请创建mysql用户和组
groupadd mysql
useradd -g mysql mysql

上传至/tmp目录,开始解压安装
cd/tmp
tarxzvftarxzvfmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz
mvmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23/opt/mysql_cluster
chownmysql.mysql-R/opt/mysql_cluster

三、管理节点(mgm)配置(mysql)
配置mgm节点的config.ini文件
[NDBDDEFAULT]
NoOfReplicas=2
[NDB_MGMD]
NodeId=1
hostname=192.168.11.12
[NDBD]
NodeId=11
hostname=192.168.11.11
datadir=/opt/mysql_cluster/ndbdata
[NDBD]
NodeId=12
hostname=192.168.11.10
datadir=/opt/mysql_cluster/ndbdata
[MYSQLD]
NodeId=21
hostname=192.168.11.13
[MYSQLD]
NodeId=22
hostname=192.168.11.14

启动mgm节点
/opt/mysql_cluster/bin/ndb_mgmd -f /opt/mysql_cluster/config.ini –configdir=/opt/mysql_cluster

四、数据节点配置(mysql)
配置ndb节点参数(/opt/mysql_cluster/my.cnf)
[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]
ndb-connectstring=192.168.11.12

创建ndbdata文件夹
mkdir /opt/mysql_cluster/ndbdata

启动ndb节点
/opt/mysql_cluster/bin/ndbd –defaults-file=/opt/mysql_cluster/my.cnf –initial

五、SQL节点配置(mysql)
初始化sql节点
/opt/mysql_cluster/scripts/mysql_install_db –user=mysql –datadir=/opt/mysql_cluster/data –basedir=/opt/mysql_cluster/

配置my.cnf文件(root)
mv /opt/mysql_cluster/my-large.cnf /etc/my.cnf
添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]
ndb-connectstring=192.168.11.12

修改mysql.server(mysql)
/opt/mysql_cluster/support-files/mysql.server中的datadir和basedir为
basedir=/opt/mysql_cluster
datadir=/opt/mysql_cluster/data

启动sql节点(mysql)
/opt/mysql_cluster/support-files/mysql.server start

六、查看集群状态(msyql)
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
———————
[ndbd(NDB)] 2 node(s)
id=11 @192.168.11.11 (mysql-5.1.56 ndb-7.1.15, Nodegroup: 0, Master)

mysql-cluster 7.x安装(windows)

mysql 集群配置(windows2台机器模拟)
1、环境规划
win7 192.168.1.1(管理节点,存储节点,sql节点)
win03 192.168.1.2(存储节点,sql节点)

2、安装cluster(zip包)
win7机器安装在D:\mysql-cluster中
win03机器安装在C:\mysql-cluster中
存储节点存储路径分别为:D:\mysql-cluster\ndbdata和C:\mysql-cluster\ndbdata

3、win7机器配置
创建D:\mysql-cluster\config.txt文件,内容为:
[NDBD DEFAULT]
NoOfReplicas=2
[NDB_MGMD]
ID=1
hostname=192.168.1.1
datadir=D:\mysql-cluster\data
[NDBD]
ID=21
hostname=192.168.1.1
datadir=D:\mysql-cluster\ndbdata
[NDBD]
ID=22
hostname=192.168.1.2
datadir=C:\mysql-cluster\ndbdata
[MYSQLD]
ID=11
hostname=192.168.1.1
[MYSQLD]
ID=12
hostname=192.168.1.2

复制D:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

4、win03机器配置
复制C:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

5、启动
5.1)启动管理节点(win7 上)
D:\mysql-cluster\bin>ndb_mgmd.exe –config-file=D:\mysql-cluster\config.txt –co
nfigdir=D:\mysql-cluster

5.2)启动存储节点(无先后顺序,第一个启动使用–initial)
win7
D:\mysql-cluster\bin>ndbd.exe –initial
win03
C:\mysql-cluster\bin>ndbd.exe

5.3)启动sql节点(无先后顺序)
win03
C:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini
win7
d:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini

6、查看是否启动成功
6.1)查看状态
D:\mysql-cluster\bin>ndb_mgm.exe
– NDB Cluster — Management Client –
ndb_mgm> show
Connected to Management Server at: 192.168.1.1:1186
