Linux系统如何设置开机默认启动应用程序？有时候我们需要Linux系统在开机的时候自动加载某些脚本或系统服务。下面良许教程网为大家分享一下Linux系统设置 开机默认启动应用程序的具体方法。
要设置如下程序helloworldlinux运行应用程序linux 下载，开机运行
[root@buildroot /usr/bin]#ls hello* helloworld [root@buildroot /usr/bin]#./helloworld hello world
1、进入目录
[root@buildroot /usr/bin]#cd /etc/init.d/ [root@buildroot /etc/init.d]#ls S01syslogd S40network rcS S02klogd X10modules rndis_host.modules S02sysctl X10userstart S20urandom rcK
2、新建 S10userstartlinux空间，注意大写’S’开头的文件linux运行应用程序，才会被rcS调用并执行！具体查看rcS文件
[root@buildroot /etc/init.d]#vi S10userstart
输入一下内容：
#!/bin/sh cd /usr/bin ./helloworld
并设置权限
[root@buildroot /etc/init.d]#chmod 755 S10userstart
4、重启 reboot

可以看到 helloworld 已经运行了！
Starting syslogd: OK Starting klogd: OK Running sysctl: OK hello world
