原因

由于使用的是openjdk，bin/tools.sh 依赖 ${JAVA_HOME}/lib/ext jar包 ，具体如下：

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m"
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"
JAVA_OPT="${JAVA_OPT} -cp ${CLASSPATH}"

所以通过定义JAVA_HOME

解决方法

rpm -qa | grep jdk
jdk1.8-1.8.0_291-fcs.x86_64

rpm -ql  jdk1.8-1.8.0_291-fcs.x86_64 |grep '/jre/lib/ext'
/usr/java/jdk1.8.0_291-amd64/jre/lib/ext

export JAVA_HOME=/usr/java/jdk1.8.0_291-amd64
