前段時間做了一個網站btdog磁力與btdog電視直播。DHT爬蟲需要消耗比較多的資源，原來的服務器不夠用了，於是自己使用電腦搭了一台服務器，使用Fedora22系統。在Fedora22中自動寫了些開機自啟動腳本，但始終找不到放在哪里。折騰了下，發現原來Fedora 從15開始，系統初始化軟件開始由initscript轉向了systemd方式，原來要寫開機啟動腳本一般寫在rc.local里面，但現在rc.local已經不存在了，不過systemd仍然有rc-local服務。
編輯/usr/lib/systemd/system/rc-local.service

可見我們只要新建文件/etc/rc.d/rc.local 然后加入自己的腳本就可以了
新建rc.local
touch /etc/rc.d/rc.local
vim /etc/rc.d/rc.local
#!/bin/bash
#下面是你需要執行的腳本
#####################################
賦以可執行權限
chmod +x /etc/rc.d/rc.local
然后使用systemd開機自啟動
systemctl enable rc-local.service
提示錯誤如下：
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...).
這個時候，我們需要在/usr/lib/systemd/system/rc-local.service 中加入[Install]區域，用於告訴systemd需要在多用戶啟動時還是圖形啟動時自啟動這個腳本
編輯/usr/lib/systemd/system/rc-local.service

好了，然后在使用systemd開機自啟動
systemctl enable rc-local.service
然后查看啟動狀態
