How to make WSL run services at startup
Solution 1
My example with mysql service
-
Create line in
/etc/sudoers
(at WSL to prevent asking password):%sudo ALL=(ALL) NOPASSWD: /usr/sbin/service mysql start
-
Create
.bat
file in Windows startup directory with this line (dir find here: Win+R andshell:startup
):wsl sudo service mysql start
After restarting the service, it will start automatically.
Solution 2
In WSL, the linux distributions run only after a first linux command is invoked. If you wanna run a linux deamon (a service) you must configure the server in linux and run any command in that linux distribution.
There are many pages and answers that show how to create a script to start a WSL linux when your computer starts.
- There is a wsl-autostart VBS script that you can use. You can install the script and change the
commands.txt
with custom linux commands. - There is a step by step tutorial to start automatically an ssh server on WSL.
- There are also options to create policies to run the program as an initial tasks (using the
gpedit.msc
command) or a scheduled task that run at startup (using thetaskschd.msc
).
NOTE: If your program must be executed with sudo
, you must configure it to start the program without asking a password.
- Run
visudo
in the linux and add a line at the end of the file:%sudo ALL=NOPASSWD: /full/path/to/program
Solution 3
With the release of Windows 11, a new feature has been added to WSL to address this. To run any arbitrary command when WSL starts, create or edit (as sudo
) /etc/wsl.conf
with the following contents:
[boot]
command="command to run as root; other command to run as root"
For instance:
[boot]
command="service ssh start; service cron start"
These commands run as root, so no need to use sudo
with a password.
Note that (currently, at least) if you attempt have multiple command=
lines, only the last will be executed. If you need multiple commands to run at boot, separate them with a semicolon as above.
If you need these services to start at Windows login, simply create a scheduled task at login for wsl true
. This will start your WSL instance, triggering the boot
commands above. Because the services are running, the WSL instance will stay up in the background.
Solution 4
Another option:
1) Create a startup file in Linux at /etc/init-wsl
:
#!/bin/sh
echo booting
service ssh start
and make the script executable
chmod +x /etc/init-wsl
2) Schedule executing this file at windows boot or log on
Since wsl.exe
is able to run commands inside the wsl distro, we simply schedule
to run this file through the command wsl -u root /etc/init-wsl
. If you have multiple distros, you might want to specify which one with a -d
flag, for instance wsl -d Ubuntu-20.04 -u root /etc/init-wsl
Solution 5
Thank you for your question, it guided me towards this solution. This is my complete, generalized- and particular solution. It consist of 3 steps:
- Create a cronjob
- Run/enable the cronjob service at startup
- Remove prompting for password to start the cronjob service automatically.
In reality your problem is already solved with just step 2 and 3, but since you tried to do it with a cronjob, I also added that step for completeness.
1. Creating a functioning cronjob:
- Browse to folder
/etc/
- Then in folder
/etc/
enter:sudo nano crontab
- In that file named crontab enter your command.
- E.g.:
*/1 * * * * root touch /var/www/myFile
- To create a file named
myFile
in location/var/www/
every minute. - For completeness:
*/1 * * * * root touch /var/www/myFile
would mean: create that file every 1st minute of the hour.
An example of the crontab
file could look like (I only added the last line, the rest was already there in my setup):
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# m h dom mon dow user command
*/2 * * * * root touch /var/www/myFile
2. Enabling cronjob service
To run a command automatically at startup of WSL Ubuntu 16.04 you can:
- cd to
/home/<your ubuntu user name>
sudo nano .bashrc
- The text editor nano then creates/opens a file
.bashrc
- In that file a lot of examples can be shown already, to just execute your command upon startup of the WSL ubuntu 16.04, write your command on the first line of the
.bashrc
file. - For example:
echo "hello world"
as shown in the picture below. - For your particular problem, the particular solution would be to enter the line:
sudo ./xmr-stak-cpu
- Close the editor with:
ctrl+x
- Save the file with
Y
- Exit ubuntu
- Restart ubuntu and verify indeed the hello world is printed before your username.
![An example command in .bashrc that is executed upon boot of WSL ubuntu.]1
For example this could be what your .bashrc
looks like after you edited it: (I only added the first line on top, the rest was already there in my setup.)
sudo -i service cron start
# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth
# append to the history file, don't overwrite it
shopt -s histappend
# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000
# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize
# If set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.
#shopt -s globstar
# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"
# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
fi
# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
xterm-color|*-256color) color_prompt=yes;;
esac
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes
if [ -n "$force_color_prompt" ]; then
if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
# We have color support; assume it's compliant with Ecma-48
# (ISO/IEC-6429). (Lack of such support is extremely rare, and such
# a case would tend to support setf rather than setaf.)
color_prompt=yes
else
color_prompt=
fi
fi
You can replace the hello world
command with sudo service cron start
to enable cronjob service. However then you are still required to enter your password manually.
3. Removing prompt for password: Using: https://askubuntu.com/questions/147241/execute-sudo-without-password
- Open WSL ubuntu 16.04 (terminal)
sudo visudo
- At the bottom of the file add line:
<your WSL ubuntu username> ALL=(ALL) NOPASSWD: ALL
- E.g with username zq you would add the following line to the bottom of the file:
zq ALL=(ALL) NOPASSWD: ALL
- ctrl+x to exit
-
y
followed by<enter>
to save. - Then again, close ubuntu and re-open it and verify
- The cron service is running automatically when you boot/open WSL ubuntu 16.04 without prompting for password.
- (you can check with command:
sudo service cron status
.)
The code to prevent prompting for password at boot would for example look like (I only added the last line, the rest was already there in my setup):
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/s$
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL:ALL) ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
%sudo ALL=NOPASSWD: /etc/init.d/cron
zq ALL=(ALL) NOPASSWD: ALL
Working towards this solution, I learned cronjobs are intended for things to run periodically rather than at specific events such as startup. To run things at startup in WSL you can use the file /home/<username>/.bashrc

After searching this site and various Q, it is clear that services and
systemd
is not available for WSL. I need to run a program in WSL every time I start my PC so I read this page on how to use crontab: How to run Ubuntu service on Windows (at startup)? Super User but I got confused because the format does not tally with the format in crontab.In addition, that particular question was specific for SSH servers which requires that the security aspect if considered and dealth with resulting in overcomplication of steps. Irrespective, the steps explored in that qusetion have been tried and they did not work. In addition, that question is highly specific to SSH servers whilst this question deals with a general enviromental requirement i. I need to know HOW to run services in WSL (which may include but is not limited to SSH serrvers)
In effect - A more simplified solution is required than How to run Ubuntu service on Windows (at startup)? provides.
However this is my cron:
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin PATH=cd /usr/local/src/:cd xmr-stak-cpu:cd bin/ @reboot . sudo ./xmr-stak-cpu
I have also done this:
Run bash/cron loop on start
Create a file called linux.bat in shell:startup
Paste: C:\Windows\System32\bash.exe -c 'while [ true ]; do sudo /usr/sbin/cron -f; done'
It does not work.
How can I run a service in WSL? Or is there a way to use Windows?
Because in Windows I have tried the following: using https://github.com/Microsoft/WSL/issues/612
Run: When the computer starts, Action: Start a program, Program: c:\Windows\system32\bash.exe, Arguments: -c "sudo /xmr-stak-cpu/bin/xmr-stak-cpu -D" Start in: /usr/local/src/
And as you guessed, it still does not work. Frankly I wish I could do this in WSL because it is my preferred way but I will take any way.
I have a workstation with 96GB RAM and as such I will prefer to use this as the dual Linux/Windows machine and not my puny laptop.
I have tasks on both Linux and Windows and really need/prefer the Linux solution provided by Windows.
I have reviewed the other question and there is a package called Mysys that seems to provide a solution however this departs from the integration provided by Microsoft which was a great way forward.

-
seanbw almost 6 yearsIt is NOT a possible duplicate but an extension of it. The routines explored in that question are way beyond what I need. In addition, this is a specific quation atht also refers to that question. You did not read that question, did you?
-
Jaime almost 6 yearsChecking your question, you are running
sudo ... xmr-stak-cpu
using a scheduled task. -- Have you ranvisudo
and included the%sudo ALL=NOPASSWD: /xmr-stak-cpu/bin/xmr-stak-cpu
to avoid problems with the command asking for a password? Do you (really) need the sudo? can you run the miner without sudo privileges?

Inigo over 5 years+1 for the wsl-autostart script. Only downside is this triggers a UAC prompt on every start up... :/
-
Inigo over 5 years...so the way I did this was to use the wsl-autostart script, but skip the instructions that tell you to create a startup item in the registry. Instead, use Task Scheduler to create a task the runs the
start.vbs
file on login with maximum user priviliges. I can now run this to quietly start the cron service in WSL every time I start my machine- works like a dream ;) -
Biswapriyo over 5 yearsCopy a section from
.bashrc
file in your answer so that reader get to know how it looks like after editing. -
a.t. over 5 years@Biswapriyo, thank you for your feedback. Initially I added a screenshot of that code but could not get it working. So I pasted the actual code.

Scott - Слава Україні over 4 years(1) Your answer is very confusing. As far as I can tell, your bottom line is to use
.bashrc
and notcrontab
. So why is approximately 60% of your answer talking aboutcrontab
? (2) The question says “I need to run a program in WSL every time I start my PC”. Your answer doesn’t run the program until the user starts WSL and logs in. This seems not to answer the question. (3) There’s no reason for a user to usesudo
to edit their own.bashrc
. If anything, that can cause problems. … (Cont’d) -
Scott - Слава Україні over 4 years(Cont’d) … (4) Your answer describes how to disable password verification of
sudo
across the board. This is widely regarded as a bad idea. Note that other answers have showed how to do this for only the required program. (5) Whencron
was written, >40 years ago, it handled only scheduled, periodic tasks. Since then, it has been extended to handle commands at boot time. -
elig about 4 yearswhy

and not juststart
? -
Andrew Koster about 4 yearsThis is the simplest solution by far, and still flexible enough to start anything.

pabouk - Ukraine stay strong over 3 yearsInstead of creating a
.bat
script you can alternatively create a task in Windows Task Scheduler and set the commandwsl sudo service mysql start
there. -
kanlukasz over 3 yearsImportant note: Do not name the
.bat
file like the command you are using inside (eg.wsl.bat
) -
jales cardoso over 3 yearsCreate line in
sudo nano /etc/sudoers
-
Neurotransmitter almost 3 yearsThis is a good approach, since you have all control whether it should be started at startup or at user's logon, specify a delay etc.
-
Chris over 2 years@jalescardoso, no, don't edit the file that way. Always use
visudo
to edit/etc/sudoers
. (This will use your system default editor, which might benano
orvi
or anything else.) -
felipecrs over 2 yearsChanges to the sudoers are not needed, neither sudo to call service, simply use
wsl -u root
. -
Admin about 2 yearsThis is great, thanks. Shame that it's yet another feature that isn't backported to Windows 10.
