My trials of installing FreePBX

Dashrender

I'm using this thread to document my progress of installing a FreePBX system in a Dev3 CentOS 6.5 at CloudatCost.

You might find this thread boring as all get out - I will sorta talk to myself in this thread explaining my thought process and solutions, even if every other Linux admin knows them, I don't and writing it down will help me remember for next time.

I'm following these directions.
http://wiki.freepbx.org/display/HTGS/Installing+FreePBX+12+on+CentOS+6.5

The install went a lot smoother once people here told me I could just SSH with Putty into the box - ok that problems solved.

The directions have a small mistake or rather omission. When you download and install FreePBX itself, they don't have to go to /usr/src before downloading and untarring the files. So after digging around for about 10 mins I realized my problem and redownloaded (probably could have copied, oh well) and untarred in the correct directory. The rest of the steps worked without an issue.

I want to keep this more secure, so I moved on to reneabling IPTables and Fail2ban

@Hubtech was installing Elastix with FreePBX on C@C not sure if he got it working.

He wanted Elastix 2.5 which is CentOS 5 only and not available on CloudatCost. They don't go back that old.

Ah, no he was trying Elastix 4.0 beta.

hey this is Dash's thread.
back to dash's failings not mine!

Not really understanding what Fail2ban did I found this helpful guide.
http://lintut.com/easy-steps-to-install-fail2ban-on-centos-6-5-protect-sshftp-using-fail2ban/

I re enabled IPTables (the original instructions have you disable them) and of course my website was no longer reachable.

-A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -p tcp --dport 443 -j ACCEPT

are added to /etc/sysconfig/iptables.

OK now I reach the website, but the homepage indicated that it wasn't right and directed me to
http://wiki.freepbx.org/display/F2/Webserver+Overrides

So I edited /etc/httpd/conf/httpd.conf
searched for "<Directory "/var/www/html">" and changed AllowOverride from None to All
and restarted the httpd service.

OK that's fixed.

After logging into the web page I notice that asterisk isn't running, or at least not connecting.

After some digging around I found out (more like remembered) I didn't disable SELinux as the original instructions stated, so asterisk wasn't working correctly. Disabling SELinux solved this.

Now I'm presented with

Some searches have lead to a possible explanation that apache might not be running as the user asterisk or I have another permissions problem.

OK three copies of retrieve_conf on the system.

./usr/src/freepbx/amp_conf/bin/retrieve_conf
./var/lib/asterisk/sounds/freepbx/amp_conf/bin/retrieve_conf
./var/lib/asterisk/bin/retrieve_conf

the first being the install archive
and the third probably being the only one I care about for now.

Check the permissions
ls -l retrieve_conf
[root@c1115759-27921 bin]# ls -l retrieve_conf
-rwxrwxr-x. 1 asterisk asterisk 37356 Apr 6 17:55 retrieve_conf

That looks OK.

Please update your modules and reload Asterisk by browsing to your server.

OK time to update
yum update

Updating:
krb5-devel x86_64 1.10.3-37.el6_6 updates 499 k
krb5-libs x86_64 1.10.3-37.el6_6 updates 766 k

these don't 'look' to be related to asterisk or FreePBX ?

Kerberos are security libraries.

OK found how to update FreePBX,

from the webpage Admin tab at top, Module Admin about 2/3 down, then click the button for it to search for updates, then Process them.

Dashrender

OK weird - i'm still getting the same error as listed above, but what's even weirder is that the time hasn't changed. I've installed the two update from yum and there were 3 modules in FreePBX that needed updating, did that (also reinstalled CID - removed it earlier to solve the asterisk problem)

Will the error report continue to show me errors even if they are cleared? Do I just have to click the Ignore this button?

Also, under summary near the top of the page, Asterisk has a yellow triangle with an explanation mark in it, but when I hover over it, it says Asterisk has been up for less than 10 mins, and then lists how long it's actually been up - is this an issue?

Dashrender

While I wait for a few answer about that I'm moving on.

I've created a user with an extension - easy enough.... but when I try to connect a Zioper softphone to it using username = ext, password (created by FPBX - really long) Domain = IP of FPBX

I won't connect - We are sorry, we are unable to connect to your PBX with the information you provided.

Check the firewall.

Use netstat -tulpn to see what is listening.
