mysql 双机热备配置

1.下蝲mysql-noinstall-5.0.45-win32.zip
2.解压到E:\mysql,然后��文件夹E:\mysql\mysql-noinstall-5.0.45-win32改�ؓE:\mysql\master
3.再解压到E:\mysql,然后��文件夹E:\mysql\mysql-noinstall-5.0.45-win32改�ؓE:\mysql\slave
4.复制E:\mysql\master\my-small.ini为E:\mysql\master\my.ini
�~�辑内容:,增加log-bin和binlog-do-db参数
�C�Z��如下:
#skip-networking
server-id = 1

# Uncomment the following if you want to log updates
#log-bin=mysql-bin

log-bin=mysql-bin
binlog-do-db = testdb1 #需同步数据�?nbsp; testdb1
binlog-do-db = testdb2 #需同步数据�?nbsp; testdb2

5.复制E:\mysql\slave\my-small.ini为E:\mysql\slave\my.ini
�~�辑内容:,修改端口,
port = 3310

�C�Z��如下:

[client]
#password = your_password
port = 3310
socket = /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port = 3310
socket = /tmp/mysql.sock
skip-locking
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K

#skip-networking
server-id = 2

# Uncomment the following if you want to log updates
#log-bin=mysql-bin

master-host=127.0.0.1
master-user=root
master-password=
master-port=3306
replicate-do-db=testdb1
replicate-do-db=testdb2

6.保存 E:\mysql\master\my.ini.和E:\mysql\slave\my.ini

7.在命令行下运行E:\mysql\master\bin\mysqld.exe,

Microsoft Windows XP [版本 5.1.2600]
(C) 版权所�?1985-2001 Microsoft Corp.

E:\mysql\master\bin>mysqld

8.再新开命��o�?�q�行E:\mysql\slave\bin\mysqld.exe

Microsoft Windows XP [版本 5.1.2600]
(C) 版权所�?1985-2001 Microsoft Corp.

E:\mysql\slave\bin>mysqld
071013 21:41:06 [Warning] The syntax for replication startup options is deprecat
ed and will be removed in MySQL 5.2. Please use 'CHANGE MASTER' instead.

9.用mysql 客户�?HeidiSQL�q�接�?127.0.0.1�?306,创徏数据库testdb1和testdb2,
�q�在数据库中新徏�?然后插入一些数�?

10.客户端连�?�?127.0.0.1�?310,可以看见数据库testdb1和testdb2,且数据库中的数据与master的数据库数据一�?

11.t查看 E:\mysql\master\data\mysql-bin.000001 和E:\mysql\master\data\mysql-bin.index,可以看到被记录的sql操作,

Tomcat,Squid,Lighttpd的https配置

Sat, 13 Oct 2007 05:50:00 GMT

4.4.6 Tomcat HTTPS配置
在server.xml里配�|�：
tomcat普通的https配置
                   maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS"
           keystoreFile="conf/.keystore"
           keystorePass="lizongbo">

Tomcat使用apr之后的ssl双向认证配置如下:

                 maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
              enableLookups="false" disableUploadTimeout="true"
              acceptCount="100" scheme="https" secure="true"
              clientAuth="true"
              SSLEngine="on" bufferSize="8192"
              SSLEnabled="true"
              SSLProtocol="all"
              SSLCipherSuite="ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL"
              SSLCertificateFile="..\conf\ca\www.crt"
              SSLCertificateKeyFile="..\conf\ca\www.key"
              SSLCACertificateFile="..\conf\ca\ca.crt"
              SSLCACertificatePath="..\conf\ca"
              SSLVerifyDepth="15"
              SSLVerifyClient="require"
               />

4.6.6 Squid HTTPS
squid.conf中加上：
https_port 3443 cert=D:/ca/www.crt key=D:/ca/www.key

4.7.6 LightTPD HTTPS
首先使用copy命��o�?key和crt合�ƈ��Z��个文�Ӟ��
D:\ca>copy /b www.key+www.crt www.pem

然后配置如下�Q?br /> $SERVER["socket"] == ":443" {
ssl.engine = "enable"
ssl.pemfile = "D:/ca/www.pem"
ssl.ca-file = "D:/ca/ca.crt"
server.name = "www"
server.document-root = "D:/httpsdosc"
server.errorlog = "httpserror.log"
accesslog.filename = "httpsaccess.log"
}
(下面的双向验证没有测试是否可�?
如需启用双向验证�Q�则�q�需下面的配�|�参敎ͼ�
ssl.verify-peer = "enable"
ssl.verify-depth = 1
参考：http://trac.lighttpd.net/trac/ticket/921

在smack中实�?Jabber-RPC (XEP-0009)

Mon, 04 Dec 2006 10:16:00 GMT

1.首先扩展一个IQ:
源代码来�?
java代码�?
http://cvs.codehaus.org/viewrep/groovy/groovy/modules/xmlrpc/src/main...

import org.jivesoftware.smack.packet.IQ;

/**
* @author John Wilson
*
*/

public class JabberRPC extends IQ {

private final String xml;

public JabberRPC(final String xml) {
this.xml = "\n" + xml + "\n";
}

public String getChildElementXML() {
return this.xml;
}

}

2.扩展一个IQProvider.
源代码来�?
http://cvs.codehaus.org/viewrep/groovy/groovy/modules/xmlrpc/src/main...
java代码�?
import org.jivesoftware.smack.packet.IQ;
import org.jivesoftware.smack.provider.IQProvider;
import org.jivesoftware.smack.util.StringUtils;
import org.xmlpull.v1.XmlPullParser;

/**
* @author John Wilson
*
*/

public class JabberRPCProvider implements IQProvider {

public IQ parseIQ(final XmlPullParser parser) throws Exception {
final StringBuffer buffer = new StringBuffer();

// skip the tag by calling parser.next()
while (true) {
switch (parser.next()) {
case XmlPullParser.TEXT:
// We need to escape characters like & and <
buffer.append(StringUtils.escapeForXML(parser.getText()));
break;

case XmlPullParser.START_TAG:
buffer.append('<' + parser.getName() + '>');
break;

case XmlPullParser.END_TAG:
if ("query".equals(parser.getName())) {
// don't save the end tag
return new JabberRPC(buffer.toString().trim());
} else {
buffer.append("');
break;
}
default:
}
}
}

}

3.在smack中注册IQProvider .
java代码�?
org.jivesoftware.smack.provider.ProviderManager.addIQProvider("query",
"jabber:iq:rpc", new JabberRPCProvider());

4.smack客户端例�?

try {
XMPPConnection con = new XMPPConnection("127.0.0.1", 5222);
con.login("username", "password");
//注册IQProvider
org.jivesoftware.smack.provider.ProviderManager.addIQProvider(
"query", "jabber:iq:rpc", new JabberRPCProvider());
// 监听所有的�?
con.addPacketListener(new PacketListener() {
public void processPacket(Packet packet) {
if (packet instanceof org.jivesoftware.smack.packet.IQ) {
org.jivesoftware.smack.packet.IQ iq =
(org.jivesoftware.smack.packet.IQ) packet;
System.out.println("rpc内容�?" + iq.getChildElementXML());
}
}

}, new org.jivesoftware.smack.filter.PacketFilter() {
public boolean accept(Packet arg0) {
return true;
}

});
con.createChat("xmlrpc.lizongbo.im").sendMessage("��试发�?");
JabberRPC jp = new JabberRPC("xmlrpc");
jp.setType(org.jivesoftware.smack.packet.IQ.Type.SET);
jp.setTo("xmlrpc.lizongbo.im");
con.sendPacket(jp);
Thread.sleep(25000);
con.close();
} catch (Exception e) {
e.printStackTrace();
}

5.服务端回应一个xmlrpc�?
wildfire中通过插�g�q�行响应:
public void processPacket(Packet p) {
if (p instanceof IQ) {
IQ iq =(IQ)p;
IQ niq=IQ.createResultIQ(iq);
Element responseElement=niq.setChildElement("query",
"jabber:iq:rpc");
try {
java.util.Vector v=new java.util.Vector();
v.add("lizongbo xmpp");
v.add("jabber-rpc lizongbo");
v.add("xep-0009 lizongbo");
XmlRpcResponseProcessor xrrp=new XmlRpcResponseProcessor();
String rs= new String( xrrp.encodeResponse(v, "UTF-8"));
org.dom4j.Document re=org.dom4j.DocumentHelper.parseText(rs);
responseElement.add(re.getRootElement());
componentManager.sendPacket(this, niq);
} catch (Exception e) {
e.printStackTrace();
}
}
}

6.客户端输出结果�ؓ:

rpc内容�?
lizongbo
xmppjabber-rpc lizongboxep-0009
lizongbo

在javaeye上看到关于sna的一些讨论，于是对sna很有好奇心，但是google了半天也没有搜烦到java webapp中关于sna的开源项目�?br />于是�l�合和同学交��之后，动手写了几个java文�g�Q�通过�q��o器对HttpSession的包装，实现java web应用的sna架构�?br />使用 snafilter之后�Q�即使web服务器挂了，只要用户�q�能讉K��其它web服务器，则可以照常维持session�?br />代码很简单，但是惛_��sf上面没有相关的东西，于是昨晚快睡觉的时候就�ȝ��请了一个项目，
刚才��d��sf的时候，没想��C��天就已经被批准了�Q�）

目前实现的snafilter是，sna会话id��Z��cookie�Q��用Memcached Server存放sna信息�?br />通过snafilter可以避免session复制的消耗，而且不需要黏性会话的配置�Q�就可以使得多个servlet容器�Q�可以同时包含不同的servlet容器�Q�比如tomcat和resin同时使用�Q�可以结合在一起实现类似failover的效果�?br />基本上可以随旉��起tomcat而不影响客户端用��P��Q?br />
在发布第一个版本之后，打算再加入其它的一些特性，�Ƣ迎大家交流意见�?br />ps1:我不太会使用sf的一些功能，�Ƣ迎大家分��n�l�验�?br />ps2:前段旉��向tomcat反映的一个小意见�Q�被新版本的tomcat采纳了，很开心：�Q?
