This article will explain in detail how to achieve CentOS boot automatically run their own scripts, Xiaobian feel quite practical, so share with you as a reference, I hope you can gain something after reading this article.

Operating System: CentOS-5.2

Target: boot automatically mount windows shared directory in local area network

The requested URL/etc/rc.d/was not found on this server.

Shell code

su cd /etc/rc.d/ vi rc.local

Second, add the script you want to execute to this file, and the whole content is as follows:

Shell code

#!/ bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local mount //192.168.0.3/data2-1 /mnt/data2-1 -o username=un,password=123 mount //192.168.0.3/data2-2 /mnt/data2-2 -o username=un,password=123 mount //192.168.0.3/data2-3 /mnt/data2-3 -o username=un,password=123 mount //192.168.0.3/data2-4 /mnt/data2-4 -o username=un,password=123 mount //192.168.0.3/data2-5 /mnt/data2-4 -o username=un,password=123

Tip: The practice here is very immature, I hope not, it is best to write a script file to call here, the structure is clearer, but note that the command to be executed is passed to su as a parameter.

Also review a VI editing command-copy

yy

p

3. Although it is done, it is still added

Linux will automatically execute the initialization program in the/etc/rc.d directory when it starts, so we can put the startup task in this directory. There are the following ways:

Option 1:

Simple, that is, the above approach,/etc/rc.d/directory initialization program a lot, rc.local is completed after all the initialization is executed, so it is appropriate to do something here.

Option 2:

The init.d directory is for executable programs, they are actually service scripts, written according to a certain format, Linux will automatically execute at startup, similar to Windows services.

1. Write the following script simpleTest:

Shell code

#!/ bin/bash #chkconfig:2345 80 05 --Specify which levels to execute, 0 generally refers to shutdown, 6 refers to restart, others are normal startup. #description:simple example service RETVAL=0 start(){ #entry function echo "simple example service is started... " } stop(){ #echo "simple example service is stopped... " } #Use case to select case $1 in start ;; stop ;; *) echo "error choice ! please input start or stop";; esac exit $RETVA

3. Run chmod +x /etc/rc.d/init.d/simpleTest to make it executable directly

4. Run chkconfig --add simpleTest to add the service to the configuration

5. Run chkconfig --list simpleTest to view the status of the service process.

Solution 3: The purpose is to mount the shared directory, so you can add it to/etc/fstab.

//192.168.0.3/data2-1 /mnt/data2-1 nfs username=un,password=123 0 0

Sorry, scenario 2, although the script can be run

# ./ simpleTest start

simple example service is started...

But I showed up at step four.

# chkconfig --add simpleTest

Error reading information in simpleTest service: No such file or directory

No further resolution. Sorry.
