求问阿里云服务器上ECS为什么下载不了halo的jar包？

islandlxl

wget https://github.com/halo-dev/halo/releases/download/v1.1.1/halo-1.1.1.jar -O halo-latest.jar
使用这个地址下载就下载很慢

johnniang

islandlxl 稍等

johnniang

islandlxl 从错误详情上看，是配置文件的错误配置导致的。

建议贴出你的配置文件。

islandlxl

johnniang 我是使用mysql数据库进行配置的，然后按照要求把H2的一些配置注释了

你可以把原文本贴出来（去掉密码即可）。

johnniang

islandlxl 因为你忘记更改 driver-class-name 了，所以导致了启动失败。

islandlxl

johnniang 哦哦，谢谢了

islandlxl

johnniang 你好，请问下 # 修改 halo.service

sudo vim /etc/systemd/system/halo.service ，这个文件夹中的配置要怎么配置啊，

[Service]
Type=simple
ExecStart=/usr/bin/java -server -Xms256m -Xmx256m -jar YOUR_JAR_PATH
ExecStop=/bin/kill -s QUIT $MAINPID
Restart=always
StandOutput=syslog

StandError=inherit

======================
YOUR_JAR_PATH要改成什么？

johnniang

islandlxl halo-latest.jar 的绝对地址。

islandlxl

johnniang 你好，我在这个文件时这样配置的为什么还是不行？

[Unit]
Description=Halo Service
Documentation=https://halo.run
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
ExecStart=/usr/bin/java/jdk1.8.0_191/bin/java -server -Xms256m -Xmx256m -jar /usr/local/halo/halo-latest.jar
ExecStop=/bin/kill -s QUIT $MAINPID
Restart=always
StandOutput=syslog

StandError=inherit

[Install]
WantedBy=multi-user.target

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
