Redis和Sidekiq在Ubuntu 16.04上使用systemd和Capistrano部署

Question

我正在使用Capistrano的systemd服务在ubuntu 16.04中部署sidekiq。

Sidekiq系统服务文件/lib/systemd/system/Sidekiq.service

#
# systemd unit file for CentOS 7, Ubuntu 15.04
#
# Customize this file based on your bundler location, app directory, etc.
# Put this in /usr/lib/systemd/system (CentOS) or /lib/systemd/system (Ubuntu).
# Run:
#   - systemctl enable sidekiq
#   - systemctl {start,stop,restart} sidekiq
#
# This file corresponds to a single Sidekiq process.  Add multiple copies
# to run multiple processes (sidekiq-1, sidekiq-2, etc).
#
# See Inspeqtor's Systemd wiki page for more detail about Systemd:
# https://github.com/mperham/inspeqtor/wiki/Systemd
#
[Unit]
Description=sidekiq
# start us only once the network and logging subsystems are available,
# consider adding redis-server.service if Redis is local and systemd-managed.
After=syslog.target network.target
# See these pages for lots of options:
# http://0pointer.de/public/systemd-man/systemd.service.html
# http://0pointer.de/public/systemd-man/systemd.exec.html
[Service]
Type=simple
WorkingDirectory=/opt//current
# If you use rbenv:
# ExecStart=/bin/bash -lc 'bundle exec sidekiq -e production'
# If you use the system's ruby:
ExecStart=/usr/local/bin/bundle exec sidekiq -e production -C config/sidekiq.yml -L log/sidekiq.log
User=deploy
Group=deploy
UMask=0002
# if we crash, restart
RestartSec=1
Restart=on-failure
# output goes to /var/log/syslog
StandardOutput=syslog
StandardError=syslog
# This will default to "bundler" if we don't specify it
SyslogIdentifier=sidekiq
[Install]
WantedBy=multi-user.target

但当使用以下命令启动sidekiq服务时，它没有显示任何错误：

sudo systemctl start/stop sidekiq

在该状态下，它抛出一个错误，退出代码为sudo systemctl status sidekiq

● sidekiq.service - sidekiq

Bundler出现在中

tt-apps-05:/usr/local/bin$ ls

Capistrno deploy.rb

set :user, "deploy"
Rake::Task["sidekiq:stop"].clear_actions
Rake::Task["sidekiq:start"].clear_actions
Rake::Task["sidekiq:restart"].clear_actions
namespace :sidekiq do
task :stop do
on roles(:app) do
execute :sudo, :systemctl, :stop, :sidekiq
end
end
task :start do
on roles(:app) do
execute :sudo, :systemctl, :start, :sidekiq
end
end
task :restart do
on roles(:app) do
execute :sudo, :systemctl, :restart, :sidekiq
end
end
end

我无法确定这里的问题是什么，任何人都能帮我吗？

试试这个：

ExecStart=/bin/bash -lc "/usr/local/bin/bundle exec sidekiq -e production -C config/sidekiq.yml -L log/sidekiq.log"
