seafile增加service管理

在树莓派安装了seafile，设置了网盘应用，设置seafile由systemctl管理。

1、创建启动，停止脚本

#!/bin/bash
cd /usr/local/src/seafile-server_7.0.5_stable_pi/seafile-server-7.0.5
sudo ./seafile.sh start
sudo ./seahub.sh start

#!/bin/bash
cd /usr/local/src/seafile-server_7.0.5_stable_pi/seafile-server-7.0.5
sudo ./seafile.sh stop
sudo ./seahub.sh stop

2、创建service文件

root@raspberrypi:/usr/lib/systemd/system# cat seafile.service 
[Unit]
Description=Seafile Service
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
User=root
ExecStart=/usr/local/src/seafile-server_7.0.5_stable_pi/seafile-server-7.0.5/start_seafile.sh
ExecStop=/usr/local/src/seafile-server_7.0.5_stable_pi/seafile-server-7.0.5/stop_seafile.sh

[Install]
WantedBy=multi-user.target

注意Type要设置oneshot代表启动一次，RemainAfterExit=yes，表示启动后仍然是active状态，否则service状态错误，不能设置restart配置，否则提示seafile.service: Service has Restart= setting other than no, which isn't allowed for Type=oneshot services. Refusing.

3、设置开机启动，并且启动服务

systemctl enable seafile.service
systemctl start seafile.service

4、查看服务状态
