Remote setup of LAMP server on CentOS 5
 

Hi folks,


Ubuntu 7.04 server amd64 (Host OS) - Fluxbox desktop
CentOS 5 x86_64 (Guest OS) - w/o desktop. X is running
UMWare - Virtualization platform
Open-ssh server and client are running on both OSs


I need to setup LAMP server on CentOS 5 remotely on Ubuntu. I have been googling a while for relevant documentation and howto with many output generated. Most of them are for Windows server. Please shed me somelight where can I find a relevant document/howto for my use. TIA



Edit:

1)
TWM - a lightweight desktop is running on CentOS 5

2)
httpd.x86_64 2.2.3-11.el5.centos installed
mysql-server.x86_64 5.0.22-2.2.el5_1.1 installed
php.x86_64 5.1.6-15.el5 installed
php-mysql.x86_64 5.1.6-15.el5 installed

have been installed on CentOS 5

So they're installed. If you have ssh access, just login and configure them to your liking. I'm not sure what exactly your asking for. Any docs that tell you what commands to run will do the job most likely. The client you're connecting from really plays no factor in setting up LAMP on the CentOS server.

Hi trickykid,


Previously I mistakenly thought it'll complicate to setup remote-access for configuring the remote server. X forwarding will be needed. Later I found out only with

$ ssh remote_server_ipaddr.


and login. That is all. Then I can configure CentOS 5 on Ubuntu console.


I haven't figured out how to sent/receive mails on Mail Server running on CentOS if only having one IP address from ISP and one domain. Any advice. TIA


Edit:

Network connection;

Server -> Router -> DSL Modem -> Internet

The router is on loan from ISP. They use it as gateway. I can't touch it.

Intranet IP address (router ip addr)
Ubuntu - 192.168.0.10
CentOS - 172.16.103.128 ( found with ifconfig)

Only one NIC on the PC

You only need one IP for a mail server and you don't necessarily need two mail servers. Pick the MTA you want to go with and go from there. Most will come standard with Sendmail, but if you want to make your life easier, I'd say pull down the postfix packages if they're not already installed and use that. I even have a quick entry on my technical blog on how to switch the default MTA in Redhat/CentOS servers:

http://clockwatching.net/~drew/blog/...y071011-080000

But choose the one your most comfortable with and read up on how to configure it. And since you're behind a router that most likely has the public IP address, you'll need to configure it to forward all the appropriate port requests to the server, like 25 to it for Mail, 80 for web, etc.

Thanks for your advice and URL


No, I won't run 2 Mail Servers. I'll stop Postfix on Ubuntu and run Sendmail on CentOS
(Remark: This is a test)

# yum list postfix
# ps aux | grep sendmail
# /etc/init.d/sendmail status
I further found follows;

1)
On CentOS Apache is already running;

https://localhost

starts "Apache 2 Test Page
powered byt Cent OS"



2)
On Ubuntu

$ ifconfig
3)
On CentOS
# ifconfig
4)
I found following on the Notes taken down during installing VMWare Server running "vmware-config.pl";

Now, CentOS can get out but no body can get in.


Any advice? TIA

The issue on your CentOS why you "can't get in" is because you are using NAT on your CentOS VMware Guest. You can either configure routing for this to work or you could change to Bridge mode which means that CentOS will show up as a host on the 192 network.

With regards to setting up Sendmail on CentOS. Have a look at this article by Stuart R. Kirk which I found useful.

HTH.

I use "bridged" connection.


On CentOS I can ping
192.168.0.10 (Ubuntu IP)
192.168.0.1 (router IP/gateway)
public IP of the Ubuntu



On Ubuntu I can ping
192.168.0.20 (CentOS IP)

on browser (running on Ubuntu)
https://public_IP:8080
can't display Apache 2 Test Page powered by CentOS

Port 8080 is forward to 192.168.0.20


Thanks for your URL. I haven't configured CentOS yet.

Satimis, sisnce you made so many posts getting Postfix working, why don't you stick with Postfix rather than Sendmail?

I'm NOT prepared to run Sendmail on CentOS 5. Since it is the default Mailer of CentOS it just comes in on running CentOS 5.


My immediate need is to make CentOS visited by Internet, NOT single way traffic. There must be somewhere blocking the incoming traffic to CentOS. It is NOT the iptables on Ubuntu. Also I can ssh connect CentOS on Ubuntu as well as on other PCs on the same network. I can ping CentOS IP on other PCs on the same network w/o packet loss

The above is the information that you provided before. But I guess you have changed the config so you now have CentOS in bridged mode, good start.

You say that you can not access via https, how about http? Because if you can ping it, surely this has to do with something else. Are you able to https or http to 192.168.0.20 from your ubuntu machine? If this works, I recommend that you try the connection from 'out side' your internal network as you probably have routing issues.

Do you have iptables running - it starts by default on a new CentOS build. Try and see if you can receive then.

Hint - when you install postfix, make sure you install system-switch-mail and run it to set the necessary variables

Oh, sorry. I changed it to bridged connection sometimes later.


No, the same. Tried many times.


No, both NOT work.

I also tried on proxydom.com http/https://public_ip:8080 without solution.


A further thought. The router is provided by ISP with password locked. I can't touch it. I made request to ISP to have port 8080 forward to 192.168.0.20 (CentOS IP addr). I double-checked it with ISP for sure. Would the router has web-base interface item on port? If YES, must I request ISP to have it enabled? Thanks


satimis

This sounds like it is something else. As you can not access the CentOS from Ubuntu even if they physically reside on the same machine it does not have anything to do with your ISP.

Is the firewall turned on on your CentOS? If it is, please turn it off during testing or let through TCP 80 & 443 for http/https access.

Is the apache listening on 80 and 443? Confirm this using:
netstat -an | grep 80
and
netstat -an | grep 443

If it isn't listening. Try restarting/starting apache

/etc/init.d/httpd restart

If you still have no luck....

Confirm that you see something like Listen 80 and Listen 443 in your /etc/httpd/conf/httpd.conf

the 443 might also have been configured in your ssl.conf.

Sorry I tried it before without improvement. After stopping iptables I http/https: public_ip:8080 on local network as well as another network.


I can't find system-switch-mail on Ubuntu repo.

Nor can I find it on Ubuntu postfix;

$ cat /etc/postfix/main.cf | grep switch
No printout
