There are quite a lot of things that cause me issues in the backend.<\/p>\n
Firstly, I got my domain name and proceeded to register my DNS nameservers.<\/p>\n
I waited for 3 days and thinking why the nameservers would not propagate to the world.<\/p>\n
It turns out that I didn’t create the DNS zone in my hosting provider and assumed that I can only create the zone after the nameservers propagated.<\/p>\n
I kept on getting an invalid hostname when trying to create a DNS zone on my hosting provider, and after I logged a ticket with them, they said I left an empty space after my domain name and causing the field being not validated correctly.<\/p>\n
It seems like stupid stuff happens everywhere when I assumed empty spaces in strings should be already trimmed before being sent to server.<\/p>\n
It is not as if I have not seen that before though so I reminded myself not be complacent anymore.<\/p>\n
<\/p>\n
HTTPS was pretty straight forward. After all the DNS records getting validated, getting Let’s Encrypt to obtain my cert was pretty easy.<\/p>\n
Then it is all about getting Apache to use the certs and redirect all http requests to https.<\/p>\n
The certs are having a validity of 90 days and can only be renewed after 60 days, so I just set a cronjob to run weekly to attempt to renew the cert.<\/p>\n
Hopefully there are no issues with this, but I need to check 2 months later.<\/p>\n
<\/p>\n
Within a few hours of bring up the server, I am already seeing frequent attempts to login to my server.<\/p>\n
That means I have to do anything I can think of to make it secure, enabling SELinux, firewall, disable password login, disable root ssh login etc.<\/p>\n
Hopefully it will remain secure, but I would need to check my logs often.<\/p>\n
<\/p>\n
The website is not able to send out emails, and after some investigation, SELinux blocked Apache from sending emails.<\/p>\n
After opening up the rule\u00a0httpd_can_sendmail, everything was fine.<\/p>\n
<\/p>\n
Not yet decided on what to post in this site yet.<\/p>\n
I suppose it will mostly be about my personal interest.<\/p>\n
<\/p>\n
Finally, welcome to my website, and don’t expect this to be updated.<\/p>\n
