前段时间做了一个网站btdog磁力与btdog电视直播。DHT爬虫需要消耗比较多的资源,原来的服务器不够用了,于是自己使用电脑搭了一台服务器,使用Fedora22系统。在Fedora22中自动写了些开机自启动脚本,但始终找不到放在哪里。折腾了下,发现原来Fedora 从15开始,系统初始化软件开始由initscript转向了systemd方式,原来要写开机启动脚本一般写在rc.local里面,但现在rc.local已经不存在了,不过systemd仍然有rc-local服务。
编辑/usr/lib/systemd/system/rc-local.service

可见我们只要新建文件/etc/rc.d/rc.local 然后加入自己的脚本就可以了
新建rc.local
touch /etc/rc.d/rc.local
vim /etc/rc.d/rc.local
#!/bin/bash #下面是你需要执行的脚本 #####################################
赋以可执行权限
chmod +x /etc/rc.d/rc.local
然后使用systemd开机自启动
systemctl enable rc-local.service
提示错误如下:
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, ...).
这个时候,我们需要在/usr/lib/systemd/system/rc-local.service 中加入[Install]区域,用于告诉systemd需要在多用户启动时还是图形启动时自启动这个脚本
编辑/usr/lib/systemd/system/rc-local.service

好了,然后在使用systemd开机自启动
systemctl enable rc-local.service
然后查看启动状态
