Instalei o Shadowsocks-r no meu servidor CentOS 7 e quero usar o systemd para gerenciá-lo. Então criei um arquivo em /etc/systemd/system chamado shadowsocks-r.service.

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

Mas o serviço não pôde ser iniciado corretamente. Ao verificar o status do serviço, abaixo está o que recebo:

shadowsocks-r.service - Shadowsocks-R Server
Loaded: loaded (/etc/systemd/system/shadowsocks-r.service; enabled; vendor preset: disabled)

May 14 10:29:46 vultr.guest shadowsocks-r[19267]: Stopping ShadowsocksR success

As mensagens shadowsocks-r são da função iniciar e parar. Pela mensagem, parece que as funções de início e parada foram executadas. Por que isso aconteceu e o que devo fazer para corrigi-lo? obrigado!

Atualizar:

Depois de correr systemctl start shadowsocks-r.service, tentei correr journalctl -xee é isso que recebo:

Agora tentei mais alguns e está confirmado que o comando systemctl realmente interrompeu o processo mesmo quando usei o comando "iniciar". Aqui está o que eu tentei:

  1. Primeiro eu começo o processo por/etc/init.d/shadowsocks-r start

E o terminal retorna:

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
  1. Então eu corrosystemctl start shadowsocks-r.service
  2. Então eu corro /etc/init.d/shadowsocks-r statuse o resultado é:ShadowsocksR is stopped

Então, mesmo quando eu iniciei o processo shadowsocks-r usando outro método, o systemctl irá eliminá-lo mesmo quando eu tentar iniciá-lo.

  1. Executando systemctl status shadowsocks-r.service, aqui está o que recebo:
    shadowsocks-r.service - Shadowsocks-R Server

Por sugestão de @Daniel B, removi a linha ExecStop no arquivo de serviço:

[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

Eu primeiro paro o processo server.py /etc/init.d/shadowsocks-r stope ele retornaShadowsocksR is stopped

Então eu corro

systemctl daemon-reload
systemctl start shadowsocks-r.service
systemctl status shadowsocks-r.service

Ainda recebo a mensagem de erro e parece que o comando systemctl não pôde iniciar o processo (antes de iniciar, pare o processo)
