Webmin搭建说明

1、下载安装包

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.840_all.deb

2、安装依赖包

apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python libapt-pkg-perl

3、安装webmin

dpkg --install webmin_1.840_all.deb

4、访问地址http://localhost:10000/
用户名:root,密码:系统root密码

VirtualBox的几种联网方式

VirtualBox有四种联网方式:

NAT:
虚拟机通过网络地址转换协议来访问宿主机网络,虚拟机可以访问宿主机可以访问的所有网络
宿主机和虚拟机之间无法通讯
而在宿主机局域网其他主机看来,虚拟机是不存在的
虚拟机之间不可以相互访问

Bridged:
虚拟机通过桥接,把自己虚拟为宿主机同一局域网的一台设备,虚拟机可以访问宿主机可以访问的所有网络
对于宿主机来说,虚拟机就是同一局域网的一台设备
而在宿主机局域网其他主机看来,虚拟机就是同一局域网的一台设备
虚拟机之间可以相互访问

HostOnly:
虚拟机宿主机可以相互访问,默认虚拟机不可以访问宿主机所在网络(宿主机可以共享网络给虚拟机,但一般不会这么用)。
虚拟机之间可以相互访问

Internal:
只有虚拟机之间可以相互访问。

具体情况如下(假设网段设置都正确):

通讯 Internal HostOnly NAT Bridge
虚拟机到宿主机 NO YES YES YES
宿主机到虚拟机 NO YES NO YES,部分网络服务受限
虚拟机到其他主机 NO NO YES YES,部分网络服务受限
其他主机到虚拟机 NO NO NO YES
虚拟机到虚拟机 YES YES NO YES

如何为不再有更新支持的Debain6安装软件

Debain6已经没有更新支持了

#会提示找不到更新源
apt-get update

为了继续按照软件,需要做两件事情:
1、修改/etc/apt/sources.list文件

# deb http://ftp.debian.org/debian/ squeeze-updates main contrib
# deb http://http.us.debian.org/debian/ squeeze contrib non-free main
# deb-src http://ftp.debian.org/debian/ squeeze-updates main contrib
deb http://archive.debian.org/debian squeeze main
deb http://archive.debian.org/debian squeeze-lts main

2、增加/etc/apt/apt.conf文件

Acquire::Check-Valid-Until false;

VBoxManage常用命令

1、常用命令

#列出全部虚拟机
VBoxManage list vms
#列出全部运行中的虚拟机
VBoxManage list runningvms
#列出虚拟机信息
VBoxManage showvminfo uuid|vmname
#开启虚拟机
VBoxManage startvm uuid|vmname
#开启虚拟机,无GUI模式
VBoxManage startvm uuid|vmname --type headless
#暂停虚拟机
VBoxManage controlvm uuid|vmname pause
#继续运行虚拟机
VBoxManage controlvm uuid|vmname resume
#按下机箱重启按钮
VBoxManage controlvm uuid|vmname reset
#断电
VBoxManage controlvm uuid|vmname poweroff
#按下机箱电影按钮
VBoxManage controlvm uuid|vmname acpipowerbutton
#按下机箱睡眠按钮
VBoxManage controlvm uuid|vmname acpisleepbutton

Windows创建符号连接

1、mklink
该命令可以创建符号链接、硬链接及快捷方式。

MKLINK [[/D] | [/H] | [/J]] Link Target

        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    specifies the new symbolic link name.
        Target  specifies the path (relative or absolute) that the new link
                refers to.

2、fsutil hardlink
该命令可以创建硬链接。

create          Create a hardlink
list            Enumerate hardlinks on a file

3、junction
该工具是SYSINTERNALS提供的,可以新增或删除符号链接。

The first usage is for displaying reparse point information, the
second usage is for creating a junction point, and the last for
deleting a junction point:
usage: junction.exe [-s] [-q] <file or directory>
       -q     Don't print error messages (quiet)
       -s     Recurse subdirectories

usage: junction.exe <junction directory> <junction target>
       example: junction d:\link c:\windows

usage: junction.exe -d <junction directory>

JMX获取Tomcat管理信息

1、首先配置JVM
JVM要放到NTFS卷中,在JVM路径下找到jmxremote.access及jmxremote.password.template两个文件。
将jmxremote.password.template复制一份为jmxremote.password,对运行用户可读,对普通用户不可读。

2、配置Tomcat启动参数
修改catalina.bat,增加下面一行

SET "JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=8686 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true"

Tomcat指定native library路径

一般,指定JVM的native library路径,只需要用下面的参数就好了

-Djava.library.path=PATH_TO_NATIVE_LIBRARY

Tomcat指定native library路径时,还是不要使用这边参数的好。
建议直接修改PATH环境变量,将dll或so放到环境变量PATH的路径下就好了。
TOMCAT默认将PATH赋值给-Djava.library.path参数的。

AXIS2跳过HTTPS证书验证的几种方式

AXIS2启用HTTPS,只需要设置truststore及密码,然后对于HTTPS协议,就会自动启用SSL通信了。

System.setProperty("javax.net.ssl.trustStore", PATH_TO_TRUSTSTORE);        
System.setProperty("javax.net.ssl.trustStorePassword", PASSWORD_OF_TRUSTSTORE);

但有时,基于种种原因,比如证书链有问题,比如证书HOST有问题,比如证书本身就有问题,说多了都是泪,这是后就要绕过HTTPS的证书验证了。总起来说,AXIS2有下面几种方式可以跳过HTTPS证书验证:

1、通过设置TrustAllTrustManager来绕过证书验证
这是一种局部设置方式,方式适合用wsdl2java生成stub代码的程序来执行,比如,客户端可以:

SSLContext sslCtx = SSLContext.getInstance("TLS");
sslCtx.init(null, new TrustManager[] {new TrustAllTrustManager()}, null);
stub._getServiceClient().getOptions().setProperty(HTTPConstants.CUSTOM_PROTOCOL_HANDLER,
    new Protocol("https",(ProtocolSocketFactory)new SSLProtocolSocketFactory(sslCtx),443));

2、通过设置CUSTOM_PROTOCOL_HANDLER来绕过证书验证
这是一种全局设置的方式。

Protocol myProtocolHandler = new Protocol("https", new NeoSecureSocketFactory(), 443);
//中心端注册CUSTOM_PROTOCOL_HANDLER
messageContext.getOptions().setProperty(HTTPConstants.CUSTOM_PROTOCOL_HANDLER, myProtocolHandler);
//客户端注册CUSTOM_PROTOCOL_HANDLER
stub._getServiceClient().getOptions().setProperty(HTTPConstants.CUSTOM_PROTOCOL_HANDLER, myProtocolHandler); 

3、注册Protocol来绕过证书验证
这是一种全局设置的方式。

Protocol.registerProtocol("https", new Protocol("https", new NeoSecureSocketFactory(), 443)); 

4、最后是NeoSecureSocketFactory.java
