Ubuntu10.04 history from installation to setup of Java Development Environment

1. Cut out an 80 GB hard drive for Ubuntu. I use lossless partitioning tools and there are many online tools. I am using acronis. disk. Director. Suite.

2. I installed Ubuntu at the cainiao level, so I only divided it into two zones, one swap, one/, I have 6 GB of memory, and four GB of swap, all of which are /.

3. After my laptop is installed, many drivers are directly driven. The video card is OK, the sound card is OK, the network is OK, and Chrome browser and some plug-ins are installed.

4. Install the input method. I installed fcitx4.0.

First put the PPA Source
Deb http://ppa.launchpad.net/wengxt/fcitx-nightly/ubuntu maverick main
The Deb-Src http://ppa.launchpad.net/wengxt/fcitx-nightly/ubuntu maverick main
Add to source list:
Sudo gedit/etc/APT/sources. List
Sudo apt-Get update // update the source Cache
Then start the installation:
Sudo apt-Get install fcitx // Of course, I have uninstalled the built-in ibus, so you do not need to set the default input method. If you do not want to uninstall
// Students can use sudo im-switch-A fcitx to set the default input method. If the input method is ineffective, another method is

// System-> Administration-> language support, In the keyboard input method system One option: fcitx

5. After installing the input method, JDK is installed, go to the Oracle official website to download, I download is jdk-6u34-linux-x64.bin.

First, create the directory where you want to install JDK. I will install JDK in/usr/lib/JVM/Java (use the mkdir password) (RM-RF is used to delete non-empty folders)

After creating the file, move the BIND file to the Java folder and use the MV password.

Next, we started to install the binfile first,Sudo chmod U + x/usr/lib/JVM/Java/jdk1.6.0 _ 34.bin

Then run,Sudo/usr/lib/JVM/Java/jdk1.6.0 _ 12.bin

Text appears until done appears.

Then configure the environment: What I configured is Profile
In /Etc Of Profile Add the last file

Java_home = "/usr/Java/jdk1.6.0 _ 21"

Export java_home

Path = $ java_home/bin: $ path

Export path

Classpath =.: $ java_home/lib/dt. jar: $ java_home/lib/tools. jar: $ classpath

Export classpath

Save close

Ubuntu may have a default JDK. To use the JDK we installed by default, perform the following operations:

Update-alternatives -- install/usr/bin/Java/usr/lib/JVM/Java/jdk1.6.0 _ 34/bin/Java 300 (the front is fixed, the following is the corresponding path of the Java you have installed)

Update-alternatives -- install/usr/bin/javac/usr/lib/JVM/Java/jdk1.6.0 _ 34/bin/javac 300

Add the installed JDK to the Java menu through this step.

Then execute

Update-alternatives -- config Java

In this step, select the default JDK



The rest is the editor and IED, and I like it!
