一、准备工作 首先得准备好硬件设施、我这里是3台机器在做群集、结构如下： 管理节点(MGM) 172.16.0.162(db1) SQL节点1(SQL1) 172.16.0.161(db2) SQL节点2(SQL2) 172.16.0.202(db3) 数据节点1(NDBD1) 172.16.0.161(db4) 数据节点2(NDBD2) 172.16.0.202(db4)
一、准备工作
首先得准备好硬件设施、我这里是3台机器在做群集、结构如下：
管理节点(MGM) 172.16.0.162(db1)
SQL节点1(SQL1) 172.16.0.161(db2)
SQL节点2(SQL2) 172.16.0.202(db3)
数据节点1(NDBD1) 172.16.0.161(db4)
数据节点2(NDBD2) 172.16.0.202(db4)
这个硬件搞定了、现在搞软件
最好下载7以上的版本、因为性能好嘛，7.2这个版本的新特性上介绍说是：自适应查询本地化(AQL) 复杂连接速度提高70多倍。当然到底是不是这样我没有测试过不清楚。
二、安装软件
解压mysql-cluster-gpl-7.2.9-win32.zip包
Management node的安装配置。
Management node一定要安装在C盘下，并且是以下的目录(这是在运行此节点时报错，说找不到相对应的目录)。在IP为172.16.0.162的机子上
生成c:/mysql/bin、C:/mysql/mysql-cluster(第一次启动后在这个文件夹会生成类似ndb_1_config.bin.1的文件，好像是为了以后启动加载的配置)
和c:/mysql/bin/cluster-logs目录，在下载解压的文件目录mysql/bin中将ndb_mgmd.exe和ndb_mgm.exe复制到172.16.0.162的c:/mysql/bin目录下。
在172.16.0.162的c:/mysql/bin下生成两个文件，my.ini和config.ini。
my.ini的内容为：
[plain]view plaincopyprint?
[mysql_cluster]
# Options for management node process
config-file=C:/mysql/bin/config.ini
[mysql_cluster] # Options for management node process config-file=C:/mysql/bin/config.ini
config.ini的内容：(注：ID不能从0开始，必须大于0)
[html]view plaincopyprint?

Data nodes的安装配置
在IP为172.16.0.161 的机子上生成D:/Program Files/mysqlcluster/datanode/mysql/bin、D:/Program Files/mysqlcluster/datanode/mysql/cluster-data、
D:/Program Files/mysqlcluster/datanode/mysql/bin/cluster-data.在下载的的解压文件夹/bin中将ndbd.exe复制到
172.16.0.161 机子的D:/Program Files/mysqlcluster/datanode/mysql /bin目录下，
并在D:/Program Files/mysqlcluster/datanode/mysql/bin目录下生成my.ini文件，文件的内容为：
[html]view plaincopyprint?
[mysql_cluster]
# Options for data node process:
ndb-connectstring=172.16.0.162 # location of management server
[mysql_cluster] # Options for data node process:ndb-connectstring=172.16.0.162 # location of management server 同理在172.16.0.202机子上配置相同的配置，也可以直接复制到172.16.0.202机子上。
SQL node的安装配置
在IP为172.16.0.161的机子上生成D:/Program Files/mysqlcluster/sqlnode目录，将下载的解压文件夹直接整个复制到D:/ProgramFiles/mysqlcluster/sqlnode/mysql目录下，在D:/ProgramFiles/mysqlcluster/sqlnode/mysql下生成my.ini文件，文件内容为：
[html]view plaincopyprint?
[html]view plaincopyprint?
[mysqld]
# Options for mysqld process:ndbcluster
[mysqld] # Options for mysqld process:ndbcluster
[html]view plaincopyprint?
# run NDB storage engine
ndb-connectstring=172.16.0.154
# location of management server
# run NDB storage engine ndb-connectstring=172.16.0.154 # location of management server同理，将D:/Program Files/mysqlcluster/sqlnode整个文件夹复制到172.16.0.202机子的相同目录下。
三、启动集群
启动各个节点是有顺序的，先是Management node，然后是Data nodes，最后是SQL nodes。
a、启动Management node在172.16.0.162机子下进入命令行，，转到c:/mysql/bin目录下，输入:
ndb_mgmd -f config.ini
(
如果报如下错误：MySQL Cluster Management Server mysql-5.5.28 ndb-7.2.9
2013-05-03 10:13:10 [MgmtSrvr] INFO -- The default config directory 'C:/Prog
ram Files/MySQL/MySQL Server 5.5/mysql-cluster' does not exist. Trying to create
it...
Failed to create directory 'C:/Program Files/MySQL/MySQL Server 5.5/mysql-cluste
r', error: 3
2013-05-03 10:13:10 [MgmtSrvr] ERROR -- Could not create directory 'C:/Progra
m Files/MySQL/MySQL Server 5.5/mysql-cluster'. Either create it manually or spec
ify a different directory with --configdir=
则在创建如下文件夹：C:Program FilesMySQLMySQL Server 5.5
)
b、启动Data node
在172.16.0.161机子下进入命令行，转到D:/Program Files/mysqlcluster/datanode/mysql/bin目录下，输入:
ndbd --connect-string="nodeid2;host=172.16.0.162:1186"
同理启动172.16.0.202机子,nodeid2是根据管理节点的配置文件
config.ini中的id决定的，如果id为2，则为nodeid2，配置文件中未指定
id，则按顺序执行。
(注)此时可通过在Management node中新开一命令行，转到
c:/mysql/bin目录下输入命令：
ndb_mgm
启动ndb_mgm.exe，之后输入命令：
ALL STATUS
查看到Data node连接是否成功.之后启动正常之后才能继续启动
SQLnode
c、启动SQL node
在172.16.0.161机子下进入命令行，转到D:/Program
Files/mysqlcluster/sqlnode/mysql/bin目录下，输入:
mysqld --console
按相同方式启动172.16.0.202下的SQL node。
(注)：可通过在Management node节点的机器下，转到c:/mysql/bin目录
下输入命令：
ndb_mgm
启动ndb_mgm.exe，之后输入命令：
SHOW
即可查看到各个节点的连接情况。
Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
