Redis 和 Sidekiq 在 Ubuntu 16.04 上使用 systemd 和使用 Capistrano 进行部署

Question

我正在使用带有 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

但是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

在状态下，它会抛出错误，退出代码为sudo systemctl status sidekiq

● sidekiq.service - sidekiq

Bundler 存在于

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

我无法确定这里有什么问题，谁能帮助我。

试试这个：

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