Chmod u + x jdk ***. binsudo./jdk ***. the bin screen continues to scroll until you enter yes/no. of course yes, press enter. After the installation is complete: add gedit/etc/profile at the end of the opened file: # set java environmentJAVA_HOME =/usr/lib/jvm/java/jdk1.6.0 _ 24 export JRE_HOME =/usr/lib/jvm/java/jdk1.6.0 _ 24/jreexport CLASSPATH =.: $ JAVA_HOME/lib: $ JRE_HOME/lib: $ CLASSPATHexport PATH = $ JAVA_HOME/bin: $ JRE_HOME/bin: $ PATH (configure the system java environment) restart to check java: java-version: java version "1.6.0 _ 24" Java (TM) SE Runtime Environment (build 1.6.0 _ 24-b07) Java HotSpot (TM) Server VM (build 19. 1-b02, mixed mode) indicates that the installation is successful.

Enter sudo sqldeveloper on the terminal to start the service. the following message is displayed: Type the full pathname of a J2SE installation (or Ctrl-C to quit ), the path will be stored and enter the jdk path. It is difficult to enter the jdk path for each startup. Modify the configuration file of sqldeveloper under/opt/sqldeveloper/bin, and restart the file (otherwise it may not take effect) # vi. /sqldeveloper/bin/sqldeveloper. conf: modify the SetJavaHome parameter to $ JAVA_HOME, and the installation is complete. The interface is good.
