main process exited, code=exited, status=203/EXEC

问题描述：

Oct 13 20:01:08 c_3.50 systemd[1]: Started etcd.
Oct 13 20:01:08 c_3.50 systemd[1]: Starting etcd...
Oct 13 20:01:08 c_3.50 systemd[1]: etcd.service: main process exited, code=exited, status=203/EXEC  //203不能执行
Oct 13 20:01:08 c_3.50 systemd[1]: Unit etcd.service entered failed state.
Oct 13 20:01:08 c_3.50 systemd[1]: etcd.service failed.

问题解决：

01、查看exe执行在配置的路径中存在不

02、脚本是否加#!/bin/bash

 注意：截图中的环境变量不允许${}，必须用实体替换或者写到EnvironmentFile中
