service-systemctl-and-daemon

前面说到了使用原码编译 transmission-daemon qbittorrent-nox nginx ,但是需要自己配置启动脚本。

transmission-daemon

之前使用 apt 安装的 tr-d ,虽然很容易可以使用 sudo systemctl enable|start|stop|status transmission-daemon,但是不得不忍受一个很长很傻的运行用户名,而且修改起来特别麻烦,文件权限也是乱的很。

文件的开头 ### 部分为LSB tags,格式比较固定,可以参考其他的修改,如果没有会有如下类似报错:

ssh.service is not a native service, redirecting to systemd-sysv-install
Executing /lib/systemd/systemd-sysv-install enable ssh
insserv: warning: script 'ssh' missing LSB tags and overrides
update-rc.d: error: ssh Default-Start contains no runlevels, aborting.

[参考文档tps://my.oschina.net/apis/blog/1647729?p=1)。

使用命令:

1
2

sudo update-rc.d transmission-daemon defaults

更新 system 脚本。

至此不出意外就可以使用

1
sudo service transmission-daemon stop|start|status

开机启动

前面的 service 可以一系统服务的方式启动 daemon,而且可以指定运行的用户名,但会不能开机自启动。

在这里卡了半天,无法成功,-f 好像很重要,删除后无法运行,无法设置开机运行。

记得备份所有 transmission-daemon 目录下的 resume 和 torrent 等文件目录。 血的教训。

# Stop dance for nginx
# =======================
#
# ExecStop sends SIGSTOP (graceful stop) to the nginx process.
# If, after 5s (--retry QUIT/5) nginx is still running, systemd takes control
# and sends SIGTERM (fast shutdown) to the main process.
# After another 5s (TimeoutStopSec=5), and if nginx is alive, systemd sends
# SIGKILL to all the remaining processes in the process group (KillMode=mixed).
#
# nginx signals reference doc:

好像不用 init.d 里面运行脚本。

flexget

这东西也可以 开机自动已 daemon 运行。
