I’m complete noob to Linux. I would like to install Let’s Encrypt certificate for one domain out of several hosted domains on this Linux installation. CetOS 6.5 Apache 2.4 I can login to a root shell on my machine. I’m also using a control panel to manage my site. I found this tutorial which looks very well written but I still don’t understand it. > **[Certbot](https://certbot.eff.org/#centosrhel6-apache)** > > Automatically enable HTTPS on your website with EFF's Certbot, deploying Let's Encrypt certificates. I know these are fundamentals but please bear with me and help me learn. To where I write those instructions provided in the tutorial? for instance $ sudo yum install epel-release this one looks different than other wget [https://dl.eff.org/certbot-auto](https://dl.eff.org/certbot-auto) chmod a+x certbot-auto How to find out what is path to my certbot? $ ./path/to/certbot-auto –apache How to arrange automatic renewal by adding a cron job? Thanks for help. ---

The commands (minus the $ ) should be typed into the root shell of the server. The cron is probably best done though your control panel ( if it has that option, as I assume you are more familiar with a GUI) ---

Some commands don’t have $ in front. Are they different? If I copy/type this command into shell will it work? ./path/to/certbot-auto –apache What to type into cron job? ---

You GUI should have some questions about when to run the cron (I'd set it to run daily ), and the command to run being "certbot renew" ---

I don't have a clear view on what is the best resource in this area for absolute beginners, but a lot of things may make a lot more sense when you've gone through something like that. In this case, after you download `certbot-auto` with `wget`, it will be in the _current directory_ that you were in when you ran the `wget` command. The current directory can be referred to with `.` so you can type `./certbot-auto --apache` in this case, to refer to running `certbot-auto` from your current directory. If you'd like, you can also find out the explicit name of this directory by running `pwd`; it might turn out to be something like `/home/bostjan` depending on the way the server is set up and what your account name on that server is. If that's the case, an alternative to the `./certbot-auto` form would be like `/home/bostjan/certbot-auto` (or the home directory abbreviation form `~/certbot-auto`). The latter two would work even if you have previously changed into some other directory via the `cd` command, while the `.` form would no longer work in that situation because the current directory would no longer be the one containing your copy of `certbot-auto`. I hope that helps. ---

> [@bostjan](#): > > How to arrange automatic renewal by adding a cron job? @serverco may be right to expect that the control panel would allow you to add one. If not, you'll need to learn to use a text editor to edit files on the server. Once you're familiar with that, you can make a file in `/etc/cron.daily` containing `#!/bin/sh /path/to/certbot-auto/certbot-auto renew` and mark that file executable with `chmod +x`. There is an alternative form involving running `crontab -e`, which will invoke a default text editor to edit the `crontab` file. However, that then requires a specific syntax indicating how often to run the job (minute hour day month dayofweek command), so the `/etc/cron.daily` version is probably simpler. ---

Thank you for the answers. As I understand I can choose to where I can install certbot? Is that right? On my server this domain has its own user. Some other users on this server have more domains associated. How do I install certbot? As a root user or as a user who “controls” this domain? To where do I install cerbot to a home decretory of this user or the default directory (I don’t know where that is)? Will I have to install certbot again for other domains? ---
