drools workbench

Drools 是一个 Java 的商业过程实现,这是 Bob McWhirter 所编写的一个开源项目,由 JBoss 和 Red Hat Inc 支持。 Drools 提供一个核心的 Business Rules Engine(BRE) 和一个网页编写规则的管理系统(Drools Workbench)和 一个 Eclipse IDE 的插件,一同构成完整的 Drools 生态。

而这篇文章则主要侧重于 Drools Workbench。



The workbench stores its data, by default in the directory $WORKING_DIRECTORY/.niogit, for example wildfly-8.0.0.Final/bin/.niogit, but it can be overridden with the system property -Dorg.uberfire.nio.git.dir.

Note In production, make sure to back up the workbench data directory.

18.1.3. System properties Here’s a list of all system properties:

org.uberfire.nio.git.dir: Location of the directory .niogit. Default: working directory

org.uberfire.nio.git.daemon.enabled: Enables/disables git daemon. Default: true

org.uberfire.nio.git.daemon.host: If git daemon enabled, uses this property as local host identifier. Default: localhost

org.uberfire.nio.git.daemon.port: If git daemon enabled, uses this property as port number. Default: 9418

org.uberfire.nio.git.ssh.enabled: Enables/disables ssh daemon. Default: true

Entware-ng 使用

Entware-ng 是一个适用于嵌入式系统的软件包库,使用 opkg 包管理系统进行管理。之前的路由器刷了 Openwrt 之后直接能用命令行安装相关命令,之后的路由器,NAS 也能安装 Entware-ng 。可以将 Entware-ng 想象成嵌入式设备的一个包管理软件,能方便的用来在嵌入式设备上安装软件,现在在官方的源上已经有超过 2000 个软件包。





在 QNAP 上安装


和普通 Linux 下的包管理一样,只要输入命令就能够联网下载相关软件。

opkg update
opkg install git

所有软件包列表可以查看 http://pkg.entware.net/binaries/armv7/Packages.html

通过 opkg 安装的软件启动脚本在 /opt/etc/init.d/ 目录

单个启动命令 /opt/etc/init.d/software_name start

每天学习一个命令:pidstat 查看进程消耗资源

pidstat 是 sysstat 工具包含的一个命令,主要用于监控 Linux Kernel 管理的进程资源占用情况,包括 CPU,IO,内存,线程等等。

The pidstat command is used for monitoring individual tasks currently being managed by the Linux kernel.

pidstat 首次运行会显示系统自开机起各项统计,之后运行将显示从上一次运行到该次运行的统计信息。


apt-get install sysstat


pidstat [options] [interval] [times]


  • -u 默认参数,显示各个进程的 CPU 统计信息
  • -r 显示各个进程的内存使用情况
  • -d 显示各个进程的 IO 使用
  • -w 显示各个进程的上下文切换
  • -p PID 指定 PID

比如常见的每一秒查看 IO 统计,统计 10 次

pidstat -d 1 10


所有进程的 CPU 统计信息

直接运行 pidstat 默认显示所有进程的 CPU 使用信息,等效于 pidstat -u -p ALL

pidstat -u 1 10

Result fields:

  • UID
  • PID
  • %usr: 进程在用户空间占用 cpu 的百分比
  • %system: 进程在内核空间占用 CPU 百分比
  • %guest: 进程在虚拟机占用 CPU 百分比
  • %wait: 进程等待运行的百分比
  • %CPU: 进程占用 CPU 百分比
  • CPU: 处理进程的 CPU 编号
  • Command: 进程名


Following command will display PID memory usage 10 times every 2 seconds:

pidstat -r 2 10

Result fields:

  • UID
  • PID
  • Minflt/s : 每秒次缺页错误次数 (minor page faults),虚拟内存地址映射成物理内存地址产生的 page fault 次数
  • Majflt/s : 每秒主缺页错误次数 (major page faults), 虚拟内存地址映射成物理内存地址时,相应 page 在 swap 中
  • VSZ virtual memory usage : 该进程使用的虚拟内存 KB 单位
  • RSS : 该进程使用的物理内存 KB 单位
  • %MEM : 内存使用率
  • Command : 该进程的命令 task name

显示 IO 统计信息

pidstat -d

Result field:

  • UID
  • PID
  • kB_rd/s: 每秒进程从磁盘读取的数据量 KB 单位 read from disk each second KB
  • kB_wr/s: 每秒进程向磁盘写的数据量 KB 单位 write to disk each second KB
  • kB_ccwr/s: 每秒进程向磁盘写入,但是被取消的数据量,This may occur when the task truncates some dirty pagecache.
  • iodelay: Block I/O delay, measured in clock ticks
  • Command: 进程名 task name

T 选项来打印更详细信息

使用 -T [TASK|CHILD|ALL] 来报告打印更详细的信息,默认 pidstat 使用 TASK,表示监控独立的任务信息。

  • TASK 报告独立的进程
  • CHILD 报告进程下所有线程的情况
  • ALL 输出进程及线程统计信息

Specific PID

To show CPU, memory, IO:

pidstat -u -p PID
pidstat -r -p PID
pidstat -d -p PID

比如要查看 PID 为 12002 的进程的 CPU 使用情况,并且要查看所有子线程,每隔 1 秒输出一次,输出 10 次,则可以

pidstat -T ALL -u -p 12002 1 10

每天学习一个命令:pidof 查找进程 PID

pidof finds the process id’s(pids) of the names programs.


pidof [name]


find chrome pid

pidof chrome
pidof -s chrome


  • -s instructs the program to only return one pid.


  • pgrep

威联通折腾篇十五:rtorrent-Pro 使用

QNAP CLUB 中淘到很多不错的应用,rtorrent-Pro 就是一款,现在作者升级了 rtorrent-pro 付费 15 欧元。这又是一款 BT 下载工具,界面非常美观。

rtorrent development for QNAP was started in 2008. Today after 10yrs from its 1st build, we provide you best Torrent app ever. rtorrent is an high performance and extra featured bittorrent client combined with simple and elegant user interface. rtorrent differentiates itself from other implementations by transferring data directly between file pages mapped to memory by the mmap() function and the network stack. On high-bandwidth connections, it claims to be able to seed at 3 times the speed of the official client. We strive to make rtorrent the best torrent client you could ever want!

rtorrent ui

支持的 QNAP 型号

  • armv7l - ARM processors: TS-x28/x31P/x31P2/x41 and more…
  • x86_64 - Intel/AMD64 CPU: TS-x51 and all higher (x53/61/63/70/71/73/77/78/80/82/88…)

如果不确定自己的 QNAP 型号,登录后台运行 uname -m 输出 CPU 架构如果是上面提到的两个就是支持的。


安装非常简单,下载应用,在后台上传安装即可。安装后默认的用户名是:rtorrent 密码是:admin.

rtorrent pro splash screen


/etc/init.d/rtorrent.sh [start|stop|restart]

Things to do





vi /share/CACHEDEV1_DATA/.qpkg/rtorrent/etc/rtorrent.conf

需要注意的是如果之前安装过其他 BT 下载工具,比如 Transmission 之类,可能会造成端口冲突 (DHT 端口),需要手工调整一下端口设置。

rtorrent 用到的端口:

  • 6881 DHT, 可在配置文件修改
  • 42000 连入端口
  • 19000

Change Paths

注意到该路径,rtorrent 相关的内容都安装在了该路径中。安装完毕之后 rtorrent 会在 Download 目录下创建名为 rtorrent 的文件夹,并且创建软链接 /share/Rdownload,rtorrent 下载的内容都会在该目录中。

In stock QNAP applications, a default Download share is used to save downloaded data from the Internet. Download share location is always static and only on the first initiated disk volume. In the default configuration, Rtorrent also uses the Download network share.

可以自定义 Rtorrent 存储的路径,创建共享文件夹名为 Rdownload,指定一块硬盘,当创建共享文件夹时,记得关闭 Rtorrent-Pro,创建成功后再启动。这样 rtorrent-Pro 就会使用新的路径。

Watch 监控目录

Transmission 之前的文章 也提到过监控某个文件夹,一旦有文件新加进去自动下载。

rtorrent 同样可以实现,默认的配置已经有配置,如果想要更加详细的了解,可以参考这里

Schedule 的语法:

# Schedule syntax: id,start,interval,command call cmd every interval seconds


schedule = watch_directory_1,20,10,"load.start=/downloads/watched/*.torrent"


用简短的一句话来总结上面的配置含义就是,定义了一个定时器,名叫 watch_directory_1, rTorrent 启动后 20 秒开始,每隔 10 秒执行一次命令,这个命令是从给定的目录中加载 torrent 文件。

  • schedule 的语法用逗号分隔四段,分别是 ID,启动,间隔时间,执行的命令
  • id 可以自行定义
  • start,rTorrent 启动后多久开始执行
  • interval ,间隔多长时间执行,如果是 0 则表示执行一次
  • load.start 表示从给定的目录(该目录必须要存在)加载 torrent 文件,这个地方除了 load.start 还可以用
    • load.start_verbose = file
    • load.verbose = file, verbose 会在终端将任何错误打印出来
    • load.normal

BT 下载的工具有很多,qBittorrent,Transmission,rtorrent, uTorrent,等等,非常多,wiki 有一张非常详细的对比图,在不同系统上都有着各自的最佳选择。对占用资源,下载效率的测试还没有来得及验证,等使用一段时间后再来更新吧。

Android Client

记得启用之后可以使用 Transdroid Android 客户端来管理 rtorrent-pro. 可以从 Google Play Store 下载,或者从官网:

安装之后在设置中添加 Server,名字,服务器类型,IP,HOST NAME,User name, password 没啥好说,这里的用户名和密码和界面上的用户名和密码一致。

在高级设置中,记得将 Port Number 设置为 6009, 或者使用 Use SSL 的话,输入 6008.

威联通折腾篇十三:替换默认 shell 为 zsh

默认 SSH 登录到 QNAP 的 login shell 可以通过 echo $SHELL 来查看到是


默认的这个 bash 是 QNAP 自带的

/bin/sh --version
GNU bash, version 3.2.57(1)-release (x86_64-QNAP-linux-gnu)
Copyright (C) 2007 Free Software Foundation, Inc.

也是一个相对比较简陋的版本,自动补全很难用,也没有语法高亮。所以想能不能把 QNAP 自带的 shell 换成日常使用的 ZSH,QNAP 本质上就是一个 Linux,所以理所当然的应该是可行的。


首先要要解决的问题是安装问题,普通的 Linux 发行版直接使用一行命令就可以完成,QNAP 可以使用 QNAP club 别人提供的版本,直接安装即可

wget https://cdn.qnapclub.eu/qpkg_artifacts/ZSH_5.7.0_x86_64/ZSH_5.7.0_x86_64.qpkg
sh ZSH_5.7.0_x86_64.qpkg

如果你参考过我之前的文章 你应该知道添加了 QNAP Club 的地址可以直接在 App Center 中直接搜索下载。

安装好之后,默认的 zsh 会安装到



SSH 登陆 QNAP 之后直接在终端输入 zsh 即可进入 zsh。

ZSH 一些强大的功能:

  • 强大的补全功能
  • 错误检查以及自动更正
  • 命令别名、路径别名
  • 强大的提示信息

默认的配置在 /opt/ZSH 中,可以自己做一些微调,比如

vi /opt/ZSH/zshrc.zsh-template
vi /root/.zshrc





如果在使用过程中发现,delete功能异常,比如delete虽然删除了字符但是向右多显示一个空格,而且不显示移动光标 那么可以编辑zsh配置文件

vi ~/.zshrc



保存, 然后执行, 使配置生效

source ~/.zshrc

Cinnamon alt+f2 命令

很早就开始用 Cinnamon 作为 Linux 的主要桌面环境,还折腾过 Cinnamon 的主题,但是其实一直没怎么关注 Alt + F2 的功能,唯一知道的命令就是 r 用来重启 Cinnamon。所以这里就总结总结 Alt+F2 可以用的命令。


-‘r’ - restart Cinnamon

  • ‘rt’ - reload the current Cinnamon theme
  • ‘lg’ - start the Looking Glass debugger (which itself seems not to be documented anywhere)

任何 Xwindows 应用

在 Alt + F2 下运行无界面的命令,比如 ls 可能得不到任何结果,但是可以运行比如 firefox 这样有窗口的命令。该命令需要在 PATH 下。


在 Alt + F2 窗口下输入文件目录可以快速使用默认文件浏览器打开该目录。
