在eclipse 安裝 OpenCV Java 作業環境 (centos7)

在eclipse 安裝 OpenCV Java 作業環境 (centos7)
Set up OpenCV for Java in Eclipse (centos7)

1. 執行eclipse
Command line:
#eclipse
or GUI:
Application >> Programming >> Eclipse.

2. 點選 Window(Menu) > Preferences >  Build Path > User Libraries 

3. 點選 New... 按鈕
輸入一個名稱 opencv ，按下OK完成後

4. 點選 opencv 後，再點選 [Add External JARs...] 按鈕
並且點選 opencv-320.jar 的資料夾，
(我的是放在 /usr/local/share/OpenCV/java)加入 jar 檔.

5. 加入 jar 檔後
點選 Native library location 再點選  [Edit]按鈕

6. 點選[External Folder...]按鈕，加入Location Path:/usr/local/share/OpenCV/java

vim顯示顏色設定

• 「.vimrc」檔案：

執行vim時會先去執行使用者家目錄下的「.vimrc」檔案(~/.vimrc)。

• 顏色方案(colorscheme)：

vim內建顏色方案功能，可以使用「colorscheme」指令來設定vim的配色主題。
vim內建顏色方案，存在「/usr/share/vim/vim??/colors」(「??」是vim的版本號碼)目錄中，副檔名為「.vim」。

$ ll /usr/share/vim/vim74/colors/

myOpenCV_Win10_Visual studio 2015

作業系統：Windows 10
開發工具：Visual Studio 2015
OpenCV版本：3.3.0   (opencv-3.3.0-vc14.exe 安裝位置為C:\opencv)

1. 修改環境變數

本機 → 內容 → 進階系統設定 → 環境變數 → path → 編輯

新增以下資料：
C:\OpenCV3.3\opencv\build\x64\vc14\bin


2. 開啟 Visual Studio 2015 並且新增專案

新增專案 → 左側「Visual C++」 → Win32 主控台應用程式→ 輸入專案名稱 → 確定 → 下一步 → 完成



3. 點選上方的「專案」→「屬性」→ 調整「平台」為“x64”



4. 對「VC++目錄」與「連結器」進行調整

設定VC++目錄 →在「Include目錄」增加“C:\OpenCV3.3\opencv\build\include”

設定VC++目錄 →在「程式庫目錄」增加“C:\OpenCV3.3\opencv\build\x64\vc14\lib”

設定連結器 →「輸入」 →在「其他相依性」增加

“opencv_world330d.lib”





5. 調整專案平台為「x64」



6. 新增 Visual C++檔於專案

「專案」 →「加入新項目」 →「C++檔(.cpp)」 →「新增」

7. 測試是否連結成功

撰寫一開啟圖檔的程式碼來測試是否連結成功

MariaDB基本安全性設定

MariaDB基本安全性設定：

安裝好 MariaDB 後，可執行 mysql_secure_installation 安全性設定工具：
mysql_secure_installation

設定 root 密碼、移除匿名登入帳號、禁止 root 從遠端登入、移除測試用的資料庫。

使用 root 帳號登入 MariaDB 伺服器：
mysql -u root -p

yum repolist - 基本 指令 用法與範例說明

列出所有的套件庫（repository）
yum repolist
yum -v repolist | less 

列出所有 EPEL 中的套件
yum --disablerepo="*" --enablerepo="epel" list available 

搜尋 EPEL 中的套件
yum --disablerepo="*" --enablerepo="epel" search mongodb 

安裝 EPEL 中的套件
 yum --disablerepo="*" --enablerepo="epel" install mongodb

 --disablerepo="*" 與 --enablerepo="epel" 參數
停用所有其他的套件庫，只使用 EPEL

chown: 無效的使用者: ‘mysql’

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/usr/bin/mysqladmin' -u root password 'new-password'
'/usr/bin/mysqladmin' -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

Please report any problems at http://mariadb.org/jira
