debian9 rc.local开机启动文件不存在解决方案 并开机启动tomcat容器

由于某些软件并没有增加开启启动的服务，很多时候需要手工添加，一般我们都是推荐添加命令到 /etc/rc.local 文件，但是 Debian 9 默认不带 /etc/rc.local 文件，而 rc.local 服务却还是自带的

cat /lib/systemd/system/rc.local.service

# This unit gets pulled automatically into multi-user.target by
# systemd-rc-local-generator if /etc/rc.local is executable.
[Unit]
Description=/etc/rc.local Compatibility
ConditionFileIsExecutable=/etc/rc.local
After=network.target

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
RemainAfterExit=yes
GuessMainPID=no

默认情况下这个服务关闭状态

systemctl status rc-local

● rc-local.service - /etc/rc.local Compatibility
   Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled)
  Drop-In: /lib/systemd/system/rc-local.service.d
           └─debian.conf
   Active: inactive (dead)

为了解决这个问题，需要手工添加一个 /etc/rc.local 文件  内容如下:

nano rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

  #这个是开机启动tomcat的脚本

  sh /server-home/tomcat8.5.32/bin/startup.sh restart

exit 0

设置权限

chmod +x /etc/rc.local

启动rc.local

systemctl start rc-local

   Loaded: loaded (/lib/systemd/system/rc-local.service; static; vendor preset: enabled)
