RedHat系列以及Ubuntu14可以通過編輯rc.local來設(shè)置開機(jī)啟動腳本析显，Ubutu18.04就需要添加開機(jī)自啟動的服務(wù)來恢復(fù)rc.local的功能签赃。
1谷异、建立rc-local.service文件,添加如下內(nèi)容：
sudo vi /etc/systemd/system/rc-local.service
###########################################################
[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
[Install]
WantedBy=multi-user.target
############################################################
2.創(chuàng)建rc.local文件并添加如下內(nèi)容：
sudo vi /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 "111111111111" > /usr/local/test.log
exit 0
############################################################
3.給rc.local加上執(zhí)行權(quán)限
sudo chmod +x /etc/rc.local
4.啟動服務(wù)并添加開機(jī)自啟動以及查看服務(wù)狀態(tài)
sudo systemctl enable rc-local
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
############################################################

5.重啟系統(tǒng)后檢查test.log文件確認(rèn)開機(jī)是否加載啟動腳本
cat /usr/local/test.log
