MySQL-Cluster-gpl-test-7.1.4b-1.rhel5.x86_64
MySQL-Cluster-gpl-tools-7.1.4b-1.rhel5.x86_64

2. 於/home/MySQL Cluster Package目錄中, 執行 rpm -Uhv *.rpm (建議全部機器都做), 若遇到 conflict 請將既有的 mysql 移除: yum -y remove mysql*

3. MGM Node Setting

a. mkdir -p /var/lib/mysql-cluster
b. vi /var/lib/mysql-cluster/config.ini (這裡有 config.ini 的基本範例http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-config-example.html)
c. 將以下內容貼上
[ndbd default]
NoOfReplicas=2
DataMemory=80M
IndexMemory=18M
[tcp default]
portnumber=2202
[ndb_mgmd]
hostname=192.168.152.139
id=1
datadir=/var/lib/mysql-cluster
[ndbd]
hostname=192.168.152.142
datadir=/var/lib/mysql-cluster
id=4
[ndbd]
hostname=192.168.152.141
datadir=/var/lib/mysql-cluster
id=3
[mysqld]
hostname=192.168.152.140
id=2
[mysqld]
hostname=192.168.152.143
id=5

4. SQL Node Setting

a. vi /etc/my.cnf (這裡有 my.cnf 的基本範例http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-config-example.html)
b. 將以下內容貼上:

[mysqld]
ndbcluster # run NDB storage engine
ndb-connectstring=192.168.152.139 ## MGM Node IP Address
[mysql_cluster]
ndb-connectstring=192.168.152.139 ## MGM Node IP Address

5. 啟動 MySQL Cluster

a. 注意啟動順序: MGM Node > Data Node > SQL Node
b. 於 MGM Node: ndb_mgmd -f /var/lib/mysql-cluster/config.ini --initial
c. 於兩台 Data Node: ndbd --initial
d. 於兩台 SQL Node: service mysql start

6. 檢查目前狀況

a. 於MGM Node: ndb_mgm -e show
b. 畫面會出現:

Connected to Management Server at: localhost:1186

Cluster Configuration

---------------------

[ndbd(NDB)] 2 node(s)

id=3 @192.168.152.141 (mysql-5.1.44 ndb-7.1.4, Nodegroup: 0)

id=4 @192.168.152.142 (mysql-5.1.44 ndb-7.1.4, Nodegroup: 0, Master)

[ndb_mgmd(MGM)] 1 node(s)

id=1 @192.168.152.139 (mysql-5.1.44 ndb-7.1.4)

[mysqld(API)] 2 node(s)

id=5 @192.168.152.143 (mysql-5.1.44 ndb-7.1.4)

7. 簡單測試

a. 資料庫要設為 Cluster 有些重點必須先知道：

Table 的 storage engine 須設為 NDBCLUSTER。

Table 必須有一個 primary key，若沒有，系統會自動新增一個隱藏的 primary key。

新增資料庫時，需在 Cluster 的每個 SQL node 手動執行新增該資料庫名稱。

新增 SQL node 時，需在該 node 手動新增那些要作同步的資料庫名稱。

b. 新增資料庫至其中一台SQL NODE:

mysql -u root -p

Enter password:

mysql> create database testDB;

mysql> use testDB;

mysql> create table testTable (id mediumint unsigned not null auto_increment primary key, name varchar(20) not null default '') engine = ndbcluster default charset utf8;

mysql> insert into testTable value(1,'test1');

mysql> insert into testTable value(2,'test2');

**注意要達到兩台同步化一定要在table建立時加入: engine = ndbcluster

c. 兩台SQL Node 均出現以下資料

mysql> select * from testTable;

+----+-------+

| id | name |

+----+-------+

| 1 | test1 |

| 2 | test2 |

+----+-------+

2 rows in set (0.04 sec)

8. 其他常用指令集:

a. MGM Node:

啟動: ndb_mgmd -f /var/lib/mysql-cluster/config.ini --initial
檢視目前狀況: ndb_mgm -e show
停止: ndb_mgm -e shutdown (它會把所有 MGM Node 和所有 Data Node 的 ndb_mgmd 和 ndbd 都停止掉, 但是mysqld 還留著)

b. Data Node:

啟動: ndbd

c. SQL Node:

啟動: service mysql start
停止: service mysql stop
重啟: service mysql restart

How to deal with XSS - Reflected issue

XSS-Reflected critical error detected by Fority, as follows:

JSP Page1 transmits some parameters to JSP page2, then page2 displays these parameters by <%=para1%> method. However, Forfity will detect some XSS Reflected critical errors

Example:

<a href="logmgt.jsp?orderName=<%=orderName%>&cateName=<%=cateName%>">Go to Another Page</a>

where, orderName and cateName come from Pasge1

References:

Recommendations from above references: Using the structured output mechanism (such as <bean:write ……> or JSTL(<c:outvalue=”……”/>) instead of using (<%=……%>)

Hence, the above source code can be recoded, as follows:

<a href="logmgt.jsp?orderName=<%c:out value="${param.orderName}"/>&cateName=<c:out value="${param.cateName}"/>">Go to Another Page</a>

Difference:

<%=orderName%> ------- <%c:out value="${param.orderName}"/>

where, the orderName can be save into request.setAttribute("orderName",request.getParameter("orderName"))

Finally, all the XSS-Reflected errors have been solved by JSTL tag.

How to use JSTL:

1. Download the required jar files (jstl-impl-1.2.jar, jstl-api-1.2.jar) from http://jstl.java.net/download.html

2. Put these jar files into WEB-INF/lib folder

3. To define the tag (<%c/> ), you should add this line (<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>) in the top of your page

Install VMC under Windows

Install rubyinstaller-1.9.2-p290.exe from http://www.rubyinstaller.org (make sure to check the boxes to add the ruby directory to your command path)
In console mode, Type: gem install vmc
If you are behind a firewall, you will get a nasty error message:
ERROR: Could not find a valid gem 'vmc' (>=0) in any repository
Install vmc gem through a proxy server, type:
gem install --http-proxy http://proxy.vmware.com:3128 (this proxy url is proxy server of your company) vmc
Tell Cloud Foundry which cloud you want to connect to. Type:
vmc target api.cloudfoundry.com (in general, you have to set the hosts info in your hosts document)

the hosts document located in C:\Windows\System32\drivers\hosts
add localhost name and its DNS, for example
11.111.111.22 api.cf-controller.test.com.tw
11.111.111.22 test.cf-controller.test.com.tw

To communicate with Cloud Foundry through a proxy server, set the environment variable "http_proxy". In the command window, type
set http_proxy=http://proxy.vmware.com:3128 (this proxy url is proxy server of your company) vmc target api.cloudfoundry.com
Login to Cloud Foundry
vmc login
Enter your email address and password
Create a simple Ruby application.
- c:\> md helloTest
- c:\> cd helloTest
- c:\helloTest\> copy nul helloTest.rb
- type the following sample code in helloTest.rb using a test editor :
- require 'sinatra'
  get '/' do
  "Hello from Cloud Foundry"
  end
Publish the application to the cloud. Type:
- c:\helloTest>vmc push helloTest (helloTest only without extension (.rb))
Would you like to deploy from the current directory? [Yn]: y
- Application Deployed URL: 'helloTest.cf-controller.cht.com.tw'? y
- Detected a Sinatra Application, is this correct? [Yn]: y
- Memory Reservation [Default:128M] (64M, 128M, 256M, 512M or 1G)
- Creating Application: OK
- Would you like to bind any services to 'helloTest'? [yN]: n
- Uploading Application:
- Checking for available resources: OK
- Packing application: OK
- Uploading (0K): OK
- Push Status: OK
- Staging Application: OK
- Starting Application: OK
modify C:\Windows\System32\drivers\hosts and add your application info:
- 11.111.111.22 helloTest.cf-controller.testcom.tw
Launch a web browser and go to your Application Deployment URL (helloTest.cf-controller.testcom.tw)
