ubuntu1804 設置開機啓動腳本

啓用開機腳本

在1804下，開機腳本功能默認是關閉的，使用如下腳原本啓用開機腳本功能

#!/bin/bash
cat << EOF >> /lib/systemd/system/rc.local.service

[Install]  
WantedBy=multi-user.target  
Alias=rc-local.service
EOF

ln -s /lib/systemd/system/rc.local.service /etc/systemd/system/

cat << EOF >> /etc/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.
echo "wayne" >> /root/wayne

exit 0
EOF

chmod +x /etc/rc.local
systemctl daemon-reload

修改開機啓動腳本/etc/rc.local，腳本內的命令會在開機時執行
