求问阿里云服务器上ECS为什么下载不了halo的jar包？

johnniang

islandlxl 不行的意思是？有错误信息还是什么错误表现。

islandlxl

johnniang 具体提示是这样
[root@izwz92ujq5zpxw3v4vxv5vz _]# sudo systemctl daemon-reload
sudo: systemctl: command not found
[root@izwz92ujq5zpxw3v4vxv5vz _]# sudo service halo start
Redirecting to /bin/systemctl start halo.service
/sbin/service: line 87: /bin/systemctl: No such file or directory

johnniang

islandlxl 你的系统是什么版本，似乎没有 systemctl 命令。

islandlxl

johnniang 阿里云服务器centos7.X版本

johnniang

islandlxl 你是通过 root 用户登录的，不加 sudo 试试呢。

islandlxl

johnniang 去掉sudo
[root@izwz92ujq5zpxw3v4vxv5vz _]# systemctl daemon-reload
-bash: systemctl: command not found

johnniang

islandlxl 你可能需要重新装 systemctl

islandlxl

johnniang 但是我用whereis systemctl以及ps -ef|grep systemctd 是有systemd的进程和systemctl的安装目录的啊，网上也说centos7.x是自带的systemctl的

johnniang

islandlxl 真的好奇怪啊，建议你去搜索一下相关的解决方案。

islandlxl

johnniang 好的我问问别人吧

johnniang

islandlxl 抱歉了，如果晚点儿还没有解决，可以联系我。 me#johnniang.me

islandlxl

johnniang 使用whereis systemctl命令可以看到对应的giz包安装目录，但是还是无法使用systemctl命令
