在 ubuntu 16.04 LTS 上安装的 gitlab 服务 目前稳定正常运行 但希望配置开机自启 不希望每次开机 都执行 sudo gitlab-ctl start 成功运行后 比如下面这样

$ sudo gitlab-ctl start

ok: run: gitaly: (pid 28489) 0s
ok: run: gitlab-workhorse: (pid 28497) 1s
ok: run: logrotate: (pid 28517) 0s
ok: run: nginx: (pid 28526) 1s
ok: run: postgresql: (pid 28532) 0s
ok: run: redis: (pid 28550) 1s
ok: run: sidekiq: (pid 28555) 0s
ok: run: unicorn: (pid 28561) 0s

目前所做的努力：

尝试 1

$ cat /etc/systemd/system/gitlab.service

[Unit]

Description=gitlab server

After=network.target

[Service]
User=root

Group=root

ExecStart=/usr/bin/gitlab-ctl start

ExecStop=/usr/bin/gitlab-ctl stop

Restart=on-failure

Type=forking

[Install]

WantedBy=multi-user.target

创建了这个 service 但是 执行后 好几个服务不成功 比如下面这样

$ systemctl status gitlab
● gitlab.service - gitlab server

尝试 2

有一个 service gitlab-runsvdir.service 但是 enable 了 并不生效 无法启动 gitlab

尝试 3

或许可以 直接放在 /etc/rc.local 的 exit 0 之前 这样来实现 开机自启 但是不希望这么做 就希望 通过 systemd 来管理

systemd 的 [Service] 中 如果 Type=forking 那么建议使用 PIDFILE=xxx 那么 PIDFILE 该怎么找呢 求 linux 大神指导
