/etc/rc.local is missing from my headless ubuntu 18.04
提问by quackingplatypus
I am currently hosting a minecraft server on ubuntu server 18.04 LTS. I have a .sh script to start the server's java file, and I would like to run it at startup so that the minecraft server starts when the physical server boots. I wished to do this via /etc/rc.local. However, I do not see rc.local in that location. Is it in a different location for this version of ubuntu, or is there an entirely different method I should use to run this .sh at startup?
我目前在 ubuntu 服务器 18.04 LTS 上托管 minecraft 服务器。我有一个 .sh 脚本来启动服务器的 java 文件，我想在启动时运行它，以便在物理服务器启动时启动 minecraft 服务器。我希望通过 /etc/rc.local 执行此操作。但是，我在那个位置没有看到 rc.local。对于此版本的 ubuntu，它是否位于不同的位置，还是我应该使用完全不同的方法在启动时运行此 .sh？

There is no "/etc/rc.local" file on Ubuntu 18.04, but you can create it.
Ubuntu 18.04 上没有“/etc/rc.local”文件，但您可以创建它。
Create the file with a text editor:
使用文本编辑器创建文件：
sudo nano /etc/rc.local
Paste the following lines and replace "COMMANDS" with the commands to be executed at system startup:
粘贴以下几行并将“COMMANDS”替换为系统启动时要执行的命令：
#!/bin/sh -e
COMMANDS
exit 0
Add the execute permission on the file:
添加文件的执行权限：
chmod +x /etc/rc.local

rc.local is disabled by default. Enable by using this command
默认情况下禁用 rc.local。使用此命令启用
sudo systemctl enable rc-local.service
