<p>4、使用记事本开始，在末尾添加：</p>

<p><strong>export JRE_HOME=/usr/local/java/jdk1.7.0_79/jre</strong></p>
<p><strong>export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH</strong></p>
<p><strong>export PATH=$JAVA_HOME/bin: $PATH</strong></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201702/201702120926204.png" /> </p>
<p>5、使用<strong>source命令</strong>使其生效。命令：<strong><font color="#ff0000">source /etc/profile</font></strong></p>
