一、报错

二、解决方案

打x的为原文本，√ 为需要替换成的内容

在Nacos-Server的 bin / startup.sh
由JAVA_OPT_EXT_FIX 配置引起启动报错

在startup.sh文件中替换下方配置

x JAVA_OPT_EXT_FIX="-Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"
√ JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"

x echo "$JAVA $JAVA_OPT_EXT_FIX ${JAVA_OPT}"
√ echo "$JAVA ${JAVA_OPT}"

x echo "$JAVA $JAVA_OPT_EXT_FIX ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out 2>&1 &
x nohup "$JAVA" "$JAVA_OPT_EXT_FIX" ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 &
√ echo "$JAVA ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out 2>&1 &
√ nohup $JAVA ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 &
