在本地确可以正常启动，检查配置文件读的同一套nacos配置，在其他服务器上部署此应用可以正常启动，执行命令jsp -l
发现无此命令，怀疑是jdk安装有问题,检查jdk版本为openjdk 重新安装jdk,最终解决问题

卸载openjdk

yum remove *openjdk*
1

安装jdk

vim /etc/profile
1

增加以下

export JAVA_HOME=/usr/local/java/jdk1.8.0_152
export JAVA_BIN=/usr/local/java/jdk1.8.0_152/bin
export JRE_HOME=${JAVA_HOME}/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
