有谁用过金蝶的Apusic应用服务器，说说感受

金蝶Apusic应用服务器60新特性
在金蝶Apusic应用服务器60旧有版本的基础上，金蝶Apusic应用服务器60具备了更多的新的特性和对以前特性的增强，情况如下。
对RIA（Rich Internet Application）的更全面支持
金蝶Apusic应用服务器60在JSF 12及标准EL的基础上作了重要扩充，在容器级别提供JSF 托管Bean与JPA实体、Spring Bean之间的双向注入管理，结合全球独创的OperaMasks SDK及一体化开发与管理环境OperaMasks Studio，真正实现基于Java EE技术RIA应用开发的全生命周期管理。
提供增强SOA基础设施
金蝶Apusic应用服务器60在50的基础上，进一步强化了SOA基础设施能力，实现对SCA/SDO技术的良好支持，并实现对第三方Web Services框架的良好兼容性，为面向SOA系统提供更为平滑的支撑能力。
实现增强的可靠性
金蝶Apusic应用服务器60不仅支持应用的垂直扩展和水平扩展，并且能够适应复杂环境下系统的扩展需求，提供配对算法、全复制算法等，实现对F5、Radware等硬件负载均衡设备及常规Web Server的全面兼容。
性能优化及提升
金蝶Apusic应用服务器60在50的基础上，进行了大量性能优化工作，包括静态资源缓存、NIO InputStream算法及长连接管理优化、>可以考虑将richtextBox里的内容在服务器端保存成一个文档，例如保存为WORD文档，WORD文档是可以同时存文字和的。数据库里只放地址。如果你非要把文字和都保存在数据库里，那就要看你用的是什么数据库了，用SQL或者ORACL或许还行，MYSQL也还可以。不过，即便是能够保存如此大的数据，读取起来也不是很方便，占用服务器资源太多。还是考虑保存成文件。另外还有一个方法，不用richtextBox，该用类似第三方的控件，比如：ewebediter什么的，都可以保存文字和。

好你要经过三次握手吧

CentOS系统安装DNS服务器方法
DNS 安装配置
在 RHEL5、6 中 DNS 都是用的是 bind 软件包，而在 RHEL/CentOS 7 用的是 unbound 安装包，配置文件也有了改变。我们来看一下：
21安装：
代码如下:
[root@linuxprobe ~]# yum -y install unbound
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management You can use subscription-manager to register
Resolving Dependencies
---> Running transaction check
---> Package unboundx86_64 0:1420-19el7 will be installed
---> Finished Dependency Resolution
·····
启动服务
代码如下:
[root@linuxprobe ~]# systemctl restart unbound //启动DNS服务
[root@linuxprobe ~]# systemctl enable unbound
ln -s ‘/usr/lib/systemd/system/unboundservice‘ ‘/etc/systemd/system/multi-usertargetwants/unboundservice‘
//下次系统重启自动启动DNS服务
22修改配置文件
unbound 安装好之后，缺省配置文件在 /etc/unbound/unboundconf。
221修改端口监听地址
相当于 RHEL6 配置文件中的：listen-on port 53 { any; };
查看默认监听地址
代码如下:
[root@linuxprobe ~]# netstat -tunlp |grep unbound
tcp 0 0 127001:53 0000: LISTEN 3333/unbound
tcp 0 0 127001:8953 0000: LISTEN 3333/unbound
tcp6 0 0 ::1:53 ::: LISTEN 3333/unbound
tcp6 0 0 ::1:8953 ::: LISTEN 3333/unbound
udp 0 0 127001:53 0000: 3333/unbound
udp6 0 0 ::1:53 ::: 3333/unbound
//默认监听本地回环地址，也就是现在只有自己能访问DNS服务，其它主机不能访问本机的DNS服务
修改监听地址代码如下:
[root@linuxprobe ~]# vim /etc/unbound/unboundconf
……
38 # interface: 0000
39 interface: 0000
……
//找到38行，复制去掉注释行，打开监听全网功能。
重启服务查看
代码如下:
[root@linuxprobe ~]# systemctl restart unbound
[root@linuxprobe ~]# netstat -tunlp |grep unbound
tcp 0 0 0000:53 0000: LISTEN 3461/unbound
tcp 0 0 127001:8953 0000: LISTEN 3461/unbound
tcp6 0 0 ::1:8953 ::: LISTEN 3461/unbound
udp 0 0 0000:53 0000: 3461/unbound
//现在53号端口监听的是0000，即所有网段都监听。
222修改允许查询的范围
在 RHEL6 中，DNS 配置文件中有这样一句：allow-query { localhost; };。此句定义的是允许向本机查询(迭代 & 递归)的主机范围，localhost 代表只有本机可以向本机查询。而在配置中，经常改 localhost 为 any，让所有主机能够向本机查询 DNS。所以，在 RHEL7 中，也要做这样的修改，只不过修改内容不同而已，如下：
代码如下:
[root@linuxprobe ~]# vim /etc/unbound/unboundconf
……
177 # access-control: 0000/0 refuse
178 access-control: 0000/0 allow
179 # access-control: 127000/8 allow
……
找到配置文件/etc/unbound/unboundconf的第177行，缺省为注释行，把内容改为允许访问，然后保存退出，重启服务即可。
223创建解析文件
RHEL/CentOS 5、6系统中，DNS 的解析文件分正向和反向两个解析文件，并且有解析文件的模板文件。但是在 RHEL7中，正反向解析文件合并为一个，并且无模板文件，需自己创建，路径可以在主配置文件中查看：
代码如下:
[root@linuxprobe ~]# vim /etc/unbound/unboundconf
……
453 # You can add locally served data with
454 # local-zone: "local" static
455 # local-data: "mycomputerlocal IN A 1920251"
//正向解析可参考语法
456 # local-data: ‘mytextlocal TXT "content of text record"‘
457 #
458 # You can override certain queries with
459 # local-data: "adserverexamplecom A 127001"
460 #
461 # You can redirect a domain to a fixed address with
462 # (this makes examplecom, >
