nacos 开启启动不起来

1，开机启动增加脚本 

/etc/rc.local

/opt/soft/nacos/bin/./startup-port.sh 8848

2，但是reboot机器之后，那nacos没有启动起来，java -version，echo $JAVA_HOME 都是有值的

3，检查/va/log/message 报如下错误

4，原因应该是root启动的时候，JAVA_HOME环境变量没有设置进去，或者就没有读到

5，修改开机启动命令

source /etc/profile
/opt/soft/nacos/bin/./startup-port.sh 8848
