18.04 开机启动(xx-net)解决方案

新装18.04,设置开机启动不成,查找方案如下:

来自:https://www.centos.bz/2018/05/ubuntu-18 ... %E7%BD%AE/
以下为内容:

ubuntu18.04不再使用initd管理系统,改用systemd。

然而systemd很难用,改变太大,跟之前的完全不同。

使用systemd设置开机启动
为了像以前一样,在/etc/rc.local中设置开机启动程序,需要以下几步:

1、systemd默认读取/etc/systemd/system下的配置文件,该目录下的文件会链接/lib/systemd/system/下的文件。一般系统安装完/lib/systemd/system/下会有rc-local.service文件,即我们需要的配置文件。
链接过来:

ln -fs /lib/systemd/system/rc-local.service /etc/systemd/system/rc-local.service
cd /etc/systemd/system/
cat rc-local.service
rc-local.service内容

[Unit]
Description=/etc/rc.local Compatibility
Documentation=man:systemd-rc-local-generator(8)
ConditionFileIsExecutable=/etc/rc.local
After=network.target

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

[Install]
WantedBy=multi-user.target
Alias=rc-local.service
1) [Unit] 区块:启动顺序与依赖关系。

2) [Service] 区块:启动行为,如何启动,启动类型。

3) [Install] 区块,定义如何安装这个配置文件,即怎样做到开机启动。

2、创建/etc/rc.local文件

touch /etc/rc.local
3、赋可执行权限

chmod 755 /etc/rc.local
4、编辑rc.local,添加需要开机启动的任务

#!/bin/bash

echo "test rc " > /var/test.log
5、执行reboot重启系统,然后查看test.log

------------------------
以下为rc.local 内容

---------------------------------
#!/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.

sudo miredo
sudo /home/han/xx-net/xx_net.sh start
#sudo /home/han/xx-net/start

exit 0
