Ubuntu 20.04 开机执行自定义脚本_ubuntu 22 启动脚本目录

#1、切换至root，建立rc-local.service文件

vim  /etc/systemd/system/rc-local.service

#2、在里面写入如下内容

[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 

#3、然后创建文件：rc.local

vim  /etc/rc.local

 #4、里面写入下面内容(就是开机所要执行的脚本) 

#!/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. 
 
#start script
 
  sudo -H -u user1 /bin/bash -c "vncserver :11 -localhost no -geometry 1440x900"
  sudo -H -u user2 /bin/bash -c "vncserver :12 -localhost no -geometry 1440x900"
 
#end script
 
echo "added sucessfully!" > /tmp/added_script.log 
 
exit 0

#5、加上权限

chmod +x /etc/rc.local

#6、启动服务

systemctl enable rc-local

#7、开启服务

systemctl start rc-local.service

#8、查看状态

systemctl status rc-local.service

部分内容如下：(注意active (running))

#9、重启并检查test.log文件

vim  /tmp/added_script.log 

#10、如果里面有内容(added sucessfully!)，则自启动脚本安装成功。
