linux、树莓派/etc/rc.local开机启动不运行的解决方法
Thu 30 May 2024
方法1 可能是/etc/rc.local没执行权限，直接赋予权限即可： sudo chmod +x /etc/rc.local
尝试运行: sudo systemctl daemon-reload
方法2 运行 sudo systemctl status rc-local 或 sudo systemctl status rc.local 查看提示信息：
[root@blog.dngz.net ~]# sudo systemctl status rc-local ● rc-local.service - /etc/rc.local Compatibility Loaded: loaded (/lib/systemd/system/rc-local.service; enabled-runtime; vendor preset: enabled) Drop-In: /lib/systemd/system/rc-local.service.d └─debian.conf /etc/systemd/system/rc-local.service.d └─ttyoutput.conf Active: failed (Result: exit-code) since Fri 2024-05-30 17:20:29 CST; 1h 21min ago Docs: man:systemd-rc-local-generator(8)
May 30 17:20:28 raspberrypi systemd[1]: Starting /etc/rc.local Compatibility... May 30 17:20:29 raspberrypi sudo[580]: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/bin/mount -o uid=pi,gid=pi /dev/sda1 /data May 30 17:20:29 raspberrypi sudo[580]: pam_unix(sudo:session): session opened for user root by (uid=0) May 30 17:20:29 raspberrypi rc.local[576]: mount: /data: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. May 30 17:20:29 raspberrypi sudo[580]: pam_unix(sudo:session): session closed for user root May 30 17:20:29 raspberrypi systemd[1]: rc-local.service: Control process exited, code=exited, status=32/n/a May 30 17:20:29 raspberrypi systemd[1]: rc-local.service: Failed with result 'exit-code'. May 30 17:20:29 raspberrypi systemd[1]: Failed to start /etc/rc.local Compatibility. 可以看到/etc/rc.local其实是启动运行了的，只是其中mount命令出现了错误，再测试一下该命令：
[root@blog.dngz.net ~]# mount -o uid=pi,gid=pi /dev/sda1 /data mount: /data: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. 果然出错了，直接不加参数mount试试 [root@blog.dngz.net ~]# mount /dev/sda1 /data 成功挂载，可能是之前一直用的pi用户以及ntfs分区格式，后来重新格式化为ext4，又更换了用户来登陆ssh操作导致的。
方法3 将/etc/rc.local里第一行的
!/bin/sh -e
改为：
!/bin/sh
保存、搞定
因为加了-e参数后，遇到一处错误就会退出整个脚本运行，导致认为/etc/rc.local没有执行的假象。
