看有相似贴已解决，就关闭了，结果按照该贴子并没有解决我的问题

需要设置 $JAVA_HOME的环境变量。检查是否已设置：

echo $JAVA_HOME

已解决，以下是步骤，前提示yum安装jdk1.8 注:$表示命令行
[root@localhost ~]# which java
/usr/bin/java
[root@localhost ~]# ls -lrt /usr/bin/java
lrwxrwxrwx 1 root root 22 9月 19 15:32 /usr/bin/java -> /etc/alternatives/java
[root@localhost ~]# ls -lrt /etc/alternatives/java
lrwxrwxrwx 1 root root 73 9月 19 15:32 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre/bin/java

[root@localhost ~]# vi /etc/profile
内容:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

保存退出执行 source /etc/profile（重要）
[root@localhost ~]# echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64

./as.sh ok了
谢谢！
