linux install jdk1.8 error bash: export JAVA_HOME = / usr / local / java / jdk1.8.0_144: No such file or directory

Yesterday the company a single physical machine configuration environment, install jdk1.8 download from the official website of oracle 1.8 tar pack and unpack, and configure the environment variables
but execution source / etc / profile encounter problems following screenshot:

bash: export JAVA_HOME=/usr/local/java/jdk1.8.0_144: 没有那个文件或目录
-bash: export JAVA_BIN=/usr/local/java/jdk1.8.0_144/bin: 没有那个文件或目录
-bash: export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/bin: 没有那个文件或目录
-bash: export CLASSPATH=.:/lib/dt.jar:/lib/tools.jar: 没有那个文件或目录
bash: export JAVA_HOME JAVA_BIN PATH CLASSPATH: 未找到命令...

See this issue, I think the unpacked directory

Confirmation, and then let the operation and maintenance colleagues to help look at the issue is not resolved, with a puzzled, at home, in their own virtual machine configuration, but no problems were encountered.
This morning, the company still came to the investigation, from the Baidu search, said jdk version median follow-digit system can lead to inconsistency, but I do not have a problem.

The trouble should end it, my software over the wall by FreeVPN Plus, google it and see the results

Open the first article, found that even with my environment variable configuration is not the same

# gedit /etc/profile
在最后添加下面代码：

export JAVA_HOME=/usr/local/java/jdk1.8.0_144
export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
export PATH=${JAVA_HOME}/bin:$PATH

The figure is a google search out, and then try to change it, do source / etc / profile

My original configuration:

[root@localhost jdk1.8.0_144]# java -version                                                   
java version "1.8.0_144"                                                                       
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)                                          
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

Sure enough success.
