解決方法

使用rpm 安裝jdk

下載jdk-8u201-linux-x64.rpm

chmod 755 jdk-8u201-linux-x64.rpm

rpm -i jdk-8u201-linux-x64.rpm

配置環(huán)境變量：

export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar

export PATH=$PATH:$JAVA_HOME/bin
