这一篇将在Ubuntu 14.04系统上安装Oracle数据库管理软件SQL Developer。
这是搭建Oracle开发环境日志的第二篇。
第一篇是:Ubuntu 14.04搭建PHP5+Apache2+Oracle环境
这一篇将在Ubuntu 14.04系统上安装Oracle数据库管理软件SQL Developer。
参考教程如下:
整个过程思路如下:
1.检查本地的jdk版本,如果过旧,则重新配置JDK环境
2.从oralce官方下载对应版本的sqldeveloper
3.解决sqldeveloper中文显示乱码
4.设置从命令行运行
安装过程:
1.检查本地jdk版本:
java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
上面是我的系统上jdk版本,如果你的版本过低,强烈建议你升级jdk版本。否则下面安装最新版本的sqldeveloper过程中,启动会提示jdk版本过低。
重新配置jdk的教程:
目前oracle官网上给出的最新版本jdk是1.8,我们直接访问下面网址下载对应版本的jdk:
具体版本需要依据你的系统来定,例如我的系统是ubuntu X64 14.04,则下载jdk-8u31-linux-x64.tar.gz版本。切记不要下载rpm格式的安装包。我们是debian/ubuntu类型的系统,不支持rpm安装文件。
下载完成,解压该文件,然后检查你的系统是否有安装过jdk,也即检查你的系统有没有如下目录:
/usr/lib/jvm
如果没有,使用
sudo mkdir /usr/lib/jvm
创建目录。如果有,则直接将我们下载下来解压好的jdk文件夹整个复制到该目录下。
接下来,配置jdk的环境变量:
sudo vim ~/.profile
在该文件下面添加如下语句:
##For jdk1.8.0_31 PATH
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_31
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
JAVA_HOME常量的路径需要依据你的实际情况进行配置。
然后是使得该配置立即生效:
source ~/.profile
不出意外,此时你再次通过java -version命令查看你的jdk版本,就可以看到和我上面一致的输出了。
即使你的系统原来已经安装过了旧版本的jdk,也不必对原来的jdk进行处理。这一过程会自动将系统的jdk设置为最新安装的版本。
2.从oracle官方下载最新版本的oracle sqldeveloper安装包:
下载时,由于是ubuntu系统,在版本选择时,请选择Other Platform版本。
下载完成后解压,将其放置在用户的主目录下,例如我的是~/giantchan/。
然后通过命令行进入该文件夹:
cd ~/用户名/sqldeveloper
运行sqldeveloper.sh
sudo ./sqldeveloper.sh
在第一次启动时,会提示你输入jdk的路径。如何查看jdk的路径呢?
which javac
我们可以通过该命令打印出jdk的目录:
/usr/lib/jvm/jdk1.8.0_31/bin/javac
我们截取到jdk1.8.0_31/这里的路径,也即:
/usr/lib/jdk1.8.0_31
切记不要带“/bin/javac”,否则会报错,原因是sqldeveloper.sh会自动寻找该目录下的bin目录。如果加上bin目录的路径,就会重复。
如果不小心添加了bin目录,,我们可以到/home/用户名/.sqldeveloper/4.1.0(版本号)/product.conf
sudo vim /home/用户名/.sqldeveloper/4.1.0(版本号)/product.conf
找到如下语句,将后面的路径修改真正的jdk的路径:
SetJavaHome /usr/lib/jvm/jdk1.8.0_31
修改完成后保存退出。
重新运行./sqldeveloper.sh文件。此时发现可以正常启动sqldeveloper了。但是客户端的界面仍然会出现中文乱码。接下来第三步是解决乱码问题。
3.解决sqldeveloper在ubuntu下的乱码问题:
我们从网上下载任何一个中文的字体ttf文件(一定是要ttf)。
然后按照教程一步一步操作:
cd JAVA_HOME/jre/lib/fonts
sudo mkdir fallback
cd fallback
cp msyh.ttf ./ #此处的msyh.ttf是字体文件,此处使用的是微软雅黑,也可以用其他字体文件,只要支持中文即可。
sudo mkfontdir
sudo mkfontscale
然后重启sqldeveloper即可。至此,sqldeveloper已经成功安装到了ubuntu上,可以正常运行了。
4.从命令行运行:
我们可以在~/.bashrc文件中添加如下命令:
#oracle sqldeveloper
alias sqld='cd ~/用户名/sqldeveloper && sudo ./sqldeveloper.sh'
然后通过source命令使设置立即生效:
source ~/.bashrc
以后就可以通过sqld命令来启动sqldeveloper软件了。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
