Installing and Configuring NGINX on CentOS

[@JuriyBura]

IMPORTANT ------------------ From 2018 and on, the setup in this video will only work if your SELinux is configured correctly (to allow nginx to connect to Node and to read files from home folder). Otherwise you will be getting "Not Found" and "Permission Denied" errors. Check out this video if that's what you are experiencing: kzbin.info/www/bejne/fpnclYGqlrF4gZI

[@RichardBronosky]

6:45 Yo, dawg! I hear you like including configurations. So I included configurations inside your included configurations. Seriously though, this is an absolutely stellar demonstration. Thank you.

[@ShaifulBorhan]

I wish I had seen this video 6 months ago. Having said that, I still learn so many things from your Deploying Node video series. A million thanks Juriy! Please keep on educating.

[@nishchhal42]

Finally after wandering in whole internet for days your video showed the exact process to do this. Thanks a lot for creating such to the point and working code.

[@jordanfromit5998]

This guide was like heroin to me, I've been trying to figure this out for hours and you just breezed right through it explaining everything. thank you so much!

[@javierlopez5877]

Very great video!! Congratulations, I was following usin docker, but your instructions where so good that I managed to follow along. Keep up the great work pleas!!

[@purovenezolano14]

Thank you so much. Super helpful. Love how you explain the flags for all the commands you use.

[@romeobotviewers]

Thank you for your great explanation.. now my nodejs running on nginx like a charm

[@distro6077]

*FIRST TIME IN MY LIFE* it worked for me but it error for the youtuber :D 8:25

I keep getting this "Not found" error page The requested URL was not found on this server. anyone has a clue?

Same

@@akshayseth669 After reading my comment again I don't think I could even help myself... Can you tell me what action gets you this error? Maybe I can help, I don't have that issue no more

[@akshayseth669]

@jean I resolved it. In server name you have to add private ip of the server.

[@jiyere]

@@akshayseth669 Ok cool!

[@sweetjs]

Hey Juriy, great video series, i think i've watched every video 3 or 4 times haha. But, did you mean to install and run Nginx as root? would it be "better" to install nginx as non-root user?

[@rakeshpk4991]

Nice intro music and good tutorial too. Thanks.

[@hnasr]

Hey Juriy great video as usual.. in 7:27 you used localhost because nginx is in the same server as nodejs correct? If Nodejs was on another server would you have used the ip instead? Question number 2, that being said how can I do this config dynamically? lets say my nodejs is hosted on ip address 192.168.1.100 then I add a new node js server on ip address 192.168.1.101 how can I scale nginx without editing this config file everytime? thanks again! we miss you here wish you post more videos or just talk randomly about software engineering topics .. btw you can answer this question in another video i think it will be useful as well..

[@JuriyBura]

For the first question - this is correct. For the second question, I haven't really heard of automated solutions, but they may exist. If you're starting to look into autoscaling groups it might make sense to look at something like AWS instead.

[@josephkim4723]

Juriy, thanks for these great tutorials! I have a question, can I add database to this configuration? In other words, would I be able to run Postgres, Node, and React all from one server? Would you recommend against it?

[@JuriyBura]

There's no problem in setting all these up on one host. React is just static files, Node you got covered in this tutorial series already, all you got to do is install Postgres.

[@josephkim4723]

@@JuriyBura awesome! thanks for the quick reply, really appreciate it. I'm gonna give it a try, hopefully it will go smoothly.

very interesting tutorial, thank you, can you give us tutorial about deployment multiple nodejs app on the same host ip address with different ports numbers

[@tanishqasharma7]

excellent video.

[@noordeenm3561]

This is way good resource ... what to specify in place of server_name if i dont have any domain name. shall i use ip address there instead ?

please post a video on configuring nginx to pick up static html file in centos7 and host it over the local network. TIA

[@mokanamedia]

The plugin you are using in Safari, the one for the Network Stats and requests, used throughout like at 10:27, where does one get that?

[@JuriyBura]

That's standard DevTools for Chrome. You can open this panel with Comman + Option + J on Mac, or F12 on Windows.

[@paulgonzalez9893]

Are there any repositories needed instead of EPEL if I'm doing this in Ubuntu 18.04?

[@mattiarasulo9934]

Hi @Juri! the final config repo url is broken! :)

[@JKhalaf]

This was great, thanks. Is there a video for how to configure ngnix for php, mysql (wordpress) ..etc?

[@JuriyBura]

Unfortunately not yet :) But that's a good idea to make one. With MySQL you don't have to do anything special with NGINX, they don't talk directly. With PHP it is a bit more interesting process. The best way to set it up would be through PHP-FPM and that includes configuring php-fpm itself, plus nginx to talk to it.

[@JuriyBura]

By the way, I moved from MySQL to MariaDB since Oracle got MySQL. MariaDB has exactly the same interface and works with exactly the same drivers, but don't have Oracle licensing issues.

[@JKhalaf]

Yes please, make one :) It is a very common issue, and n00bs like me find quality videos such as yours very helpful.

[@JKhalaf]

aye, I have MariaDb setup on my server, but I want to move from Apache to Ngnix, and I don't know how.

[@segaboy9894]

I want to use reverse proxy to say "service a:8083" is www.mydomain.com/servicea. I have failed so many times.

Hi thanks man this really helped me

[@soldadopreciso]

hello pal, how set a FQDN and a static ip in my RHEL server? Like you have there, can anyone have a link to a tutorial?. Or how can we configure the typical parameters of a RHEL sever after a fresh installation?

When I am trying to start nginx service its showing error " Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. "

[@prabhmeetsinghsarna1396]

Brother were you able to resolve it?

[@DarrensTechTutorials]

I still don't have a clue if it's epel or E.P.E.L 😂

[@sushantkoul7777]

you didnt showed what is pm2 because i got the error command not found

[@JGlezRg]

hi man, thx for the tutorial but when i reach to 9:34 and the error triggers in my page i havent pm2 so i cant start it. is there any other way so i can use my nginx without pm2?

[@JuriyBura]

Yes, just start node.js process normally with screen or nohup, so that it does not terminate when you log off.

[@rajeshchawla3571]

follow the steps and done with settings no error showing but not able to access URL without 3000 port

[@ПетроКобзар]

In my case I writed in conf file server_name: url of my site. But instead I was trying in browser my server Ip. (without port 8080) So by url I could get my site.

[@TensaiTech]

in your config file 7:27 try to use 127.0.0.1 instead of localhost

how to running nginx on browser ? please help me

[@haydermajli804]

Hay Juriy When i try systemctl start nginx then back this error Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. PLZ HELP

[@JuriyBura]

I would suggest to do exactly what it says: run "journalctl -xe" and check the latest failure, it will tell you more about the root cause. Quite likely you just have an error in config syntax.

[@haydermajli804]

that because your node port 80... plz change to other port like 8080 and retry

[@inkajoo]

I'm using a VPS on GoDaddy and can't figure out how to actually access my website with the browser. The hostname at the top of the page doesn't work. Can anyone give me some help?

[@pindi251210]

Don't know your exact problem but you might want to look up SSH. It's how you connect to servers (your VPS), sorry if that's not what you asked.

[@anhvuuc8693]

Thank you so much but I dont know why my nginx not run :( Anyone have a link to read? st like step by step install nodejs :( run in local pc is dream, but run on VPS is a madnight

[@whatthedoctype2565]

systemctl command not found i have centos 6

[@barioualarou6008]

You should type Service nginx start

[@whatthedoctype2565]

i made another server name for http and one for www. because it wasnt loading my website with www. is that right or wrong so what i did was make another server underneith

[@JuriyBura]

Basically yes, you add another "server" block and inside that block you redirect from WWW to regular non-www: server { server_name www.foo.com; return 301 $scheme://foo.com$request_uri; }

[@arubachannel7426]

Error systemctl start nginx Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

[@JuriyBura]

Well, seems that something is wrong :) Do what the message suggests: run journalctl -xe and try to see if that helps to understand why exactly nginx wasn't happy.

[@arubachannel7426]

Thanx i finde the problem. My VPS is 512 Mb of RAM and cant start NGINX

[@JuriyBura]

Hmm, that sounds very strange, 512Mb is plenty for Nginx. I'm quite sure that default configuration was starting just fine on 512 megs.

[@arubachannel7426]

i don't know where i add more RAM {1GB } everything work great

[@JuriyBura]

Well :) then that's great that it worked at the end.

[@codingdiva4906]

Hmm, my conf file looks much different. User is www-data. Also, I can't get anything to work on port 80, even though my netstat -tln says tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN . If i put my site on a port, it works fine, it just stubbornly won't server anything on port 80 (firewall is off so it's not that)...

[@JuriyBura]

Are you using CentOS and you use Digital Ocean installation? Distros may be slightly different across providers, so the config can be slightly different too. Can you tell a bit more about your system?

[@kman889]

Well mine is a nodejs one click install running on ubuntu 16 and mine doesnt even have a server config. its all commented out

[@JuriyBura]

The configs on nginx can be slightly different on different installations (the initial default config that is available after an install). Yet the principles of organising those configs, and what each block does, remains the same. I published my configs that I used in this video here on github: github.com/Juriy/easyio

[@whatthedoctype2565]

try and turn of apache because that runs on port 80 thats what i did and im good to go

[@JustinDuijn]

Your saying Apple. It's pronounced E-pel.

[@karmavil4034]

Are you serious? Did you install Nginx to avoid run your app as root and you ended up running your app with sudo after 20 minutes of video? Jesus..

[@JuriyBura]

Where exactly am I running it as sudo?
