![systemctl 无法启动服务(代码=退出状态=0/成功)](https://linux22.com/image/1591337/systemctl%20%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8%E6%9C%8D%E5%8A%A1%EF%BC%88%E4%BB%A3%E7%A0%81%3D%E9%80%80%E5%87%BA%E7%8A%B6%E6%80%81%3D0%2F%E6%88%90%E5%8A%9F%EF%BC%89.png)
我在 CentOS 7 服务器上安装了 Shadowsocks-r,我想使用 systemd 来管理它。因此我在 /etc/systemd/system 中创建了一个名为 shadowsocks-r.service 的文件。
shadowsocks-r.service:
[Unit]
Description=Shadowsocks-R Server
After=network.target
[Service]
ExecStart=/usr/local/shadowsocks/server.py -c /etc/shadowsocks-r/config.json -d start
ExecStop=/etc/init.d/shadowsocks-r stop
[Install]
WantedBy=multi-user.target
但服务无法正确启动。检查服务状态时,我得到以下信息:
shadowsocks-r.service - Shadowsocks-R Server

shadowsocks-r 消息来自启动和停止函数。从消息来看,启动和停止函数似乎都已执行。为什么会发生这种情况?我应该怎么做才能纠正它?谢谢!
更新:
跑步后systemctl start shadowsocks-r.service
我尝试跑步journalctl -xe
,这是我得到的结果:

现在我又尝试了几次,确认即使我使用命令“start”,systemctl 命令实际上也会停止该进程。以下是我尝试的:
- 首先我开始
/etc/init.d/shadowsocks-r start
终端返回:
IPv6 support
2019-05-16 08:39:30 INFO util.py:94 loading libcrypto from libcrypto.so.10
2019-05-16 08:39:30 INFO shell.py:74 ShadowsocksR 2.8.2
started
Starting ShadowsocksR success
- 然后我跑
systemctl start shadowsocks-r.service
- 然后我运行
/etc/init.d/shadowsocks-r status
,结果是:ShadowsocksR is stopped
因此,即使我使用其他方法启动了 shadowsocks-r 进程,systemctl 也会在我尝试启动它时将其终止。
- 运行后
systemctl status shadowsocks-r.service
,我得到的结果如下:
shadowsocks-r.service - Shadowsocks-R Server

根据@Daniel B 的建议,我删除了服务文件中的 ExecStop 行:
[Unit]
Description=Shadowsocks-R Server
After=network.target
[Service]
ExecStart=/usr/local/shadowsocks/server.py -c /etc/shadowsocks-r/config.json -d start
[Install]
WantedBy=multi-user.target
我首先停止 server.py 进程,/etc/init.d/shadowsocks-r stop
然后它返回ShadowsocksR is stopped
然后我跑
systemctl daemon-reload
systemctl start shadowsocks-r.service
systemctl status shadowsocks-r.service
我仍然收到错误消息,并且似乎 systemctl 命令无法启动该进程(在启动之前先停止该进程)
shadowsocks-r.service - Shadowsocks-R Server
