Centos7 boot/etc/rc. local not executed

Centos7 boot/etc/rc. local not executed

Recently, it was found that centos7's/etc/rc. local won't be started, so I carefully read the/etc/rc. local file and found the cause of the problem.

#!/bin/bash #THISFILEISADDEDFORCOMPATIBILITYPURPOSES # #Itishighlyadvisabletocreateownsystemdservicesorudevrules #torunscriptsduringbootinsteadofusingthisfile. # #Inconstrasttopreviousversionsduetoparallelexecutionduringboot #thisscriptwillNOTberunafterallotherservices. # #Pleasenotethatyoumustrun'chmod+x/etc/rc.d/rc.local'toensure #thatthisscriptwillbeexecutedduringboot.

Translation:

# This file is added for compatibility issues. # # We strongly recommend that you create your own systemd service or udev rules to run scripts at startup instead of using this file. # # This script will not be executed after all other services compared with the parallel execution during previous version boot. # # Remember, you must execute "chmod + x/etc/rc. d/rc. local" to ensure that this script is executed during boot.

So I confirmed the permission for/etc/rc. local.

[root@localhost~] #ll/etc/rc.local Lrwxrwxrwx.1rootroot13 October /etc/rc . local ->rc.d /rc . local [root@localhost~] #ll/etc/rc.d/rc.local -Rw-r --. 1rootroot477, December 7, June 10 /etc/rc .d /rc . local

/Etc/rc. d/rc. local has no execution permission, so it is executed according to the description.

chmod +x /etc/rc .d /rc . local

After the restart, it is found that/etc/rc. local can be executed.

It looks like the version changes./etc/rc. local/etc/rc. d/rc. local is on the road of discarding.
