怎么在mysql建立数据库

大概类似海宇安全这种软件吧，包括以下一些功能：

文档安全管理

· 监控文档的各项 *** 作

详细记录所有文档 *** 作，对重要文档做了违规 *** 作后，系统会迅速向控制台报警，并阻止该 *** 作

· 防止利用移动存储泄露机密

通过对文档的访问设置读写权限，防止将文档复制到移动存储设备中

· 防止通过网络共享泄露机密

防止将文档通过网络共享的方式传送到网络上

· 防止利用外接设备泄露机密

通过禁用各种外部设备（如软驱、U盘等移动存储设备及红外、USB等通讯设备）来防止非法复制和传送数据

· 防止利用互联网泄露机密

控制通过邮件、FTP、P2P软件、即时通讯工具等传送文档，防止企业的机密资料通过互联网传递到外界

· 防止非法接入内网窃取机密

对于未授权的外来计算机即使非法互联，也无法访问共享文件夹或进行通信，有效杜绝任何泄密可能

· 通过自动加密e799bee5baa6e79fa5e98193e58685e5aeb931333431373862机制加强安全防护

存储文档自动加密，只有在授信的环境中才能打开，即使被泄露出去，非授信环境中也无法读取

行为管理

· 应用程序管控

记录并统计各类应用软件的使用情况，有效地评估工作效率。对于禁止使用的软件及时报警，并终止使用

· 网站浏览管控

对上网行为进行监控，详细记录访问过的网址，并对网站浏览进行统计，从而分析互联网资源的使用情况

· 详细事件日志

详细记录计算机的每项 *** 作，便于管理者做相关的审计工作

· 网络流量管控

通过对上传下载的网络通讯进行统计，控制网络流量，合理分配互联网带宽资源，同时可以对网络通讯的端口和地址进行控制，限制或彻底禁止网络游戏、在线试听、聊天及BT下载

· 屏幕监控

实时查看计算机的屏幕活动画面。便于在发生违规 *** 作后重现当时景象，追根溯源

· 邮件内容管控

记录所有发送和接收的邮件的详细内容，包括附件

· 即时通讯管控

监控各种即时通讯工具的聊天内容，以及通过其传递的文档

系统管理

· 资产管理

详细记录每台计算机的软硬件资产信息，还可以定义各项资产的厂商、规格、版权等辅助信息

记录硬件设备的异动，软件的安装和卸载，并能对异动情况及时报警

自动汇总硬件配置，统计软件资产

快速部署和安装第三方软件到企业内各台计算机，例如ERP系统的客户端，办公插件，Office补丁程序

派发文件或通告等文档到客户端指定的位置，减轻管理员的工作，提高效率

· 补丁管理

定时检查和下载系统安全补丁，并在网络内自动分发和安装

· 远程维护

管理员可以远程实时查看计算机，例如进程列表，服务列表等，帮助管理员分析和解决远程计算机故障

能够像 *** 作本机一样 *** 作远程计算机，快速解决远程计算机故障

管理员可以和远程计算机进行文件互传，方便传递诊断工具和获取信息文档

用MD5加密以下为MD5文件内的源代码，然后在别的网页中嵌入，用md5(字段名)就可以实现加密效果了

在etc/nginx目录下，新建一个文件夹server,在文件夹里面新建conf文件。然后把下面的代码拷贝进去就好了，如图： 然后在etc/nginx/nginixconf 主配置文件里用Include引入这个文件就好了。如图：然后重启一下服务就好了，重启Nginx就好了，重启命令：service nginx restart。是不是很简单， `(∩_∩)′。 此外还有，另外一个编译的小细节要注意的是，开发是的模式是dev,编译部署之前要把模式修改为prod,除了要改conf里面的，还要改main函数里面的，不然会有问题。
