My trials of installing FreePBX

@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.

Not having any luck getting my extensions to connect I've decided to start over and document even better this time.

Again starting with a C@C Dev3 CentOS 6.5 box.

Following http://wiki.freepbx.org/display/HTGS/Installing+FreePBX+12+on+CentOS+6.5

Time to disable selinux
sed -i 's/(^SELINUX=)./\SELINUX=disabled/' /etc/sysconfig/selinux*

reboot and check status with sestatus which shows

SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

Uh - Houston, we have a problem. Let's look at /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted </code></pre>

OK this matches the instructions, but isn't working. Google tells me that I need to change a different file to disable selinux. http://www.shayanderson.com/linux/disable-selinux-on-centos-6.htm

This page tells me I need to change SELINUX=disabled in /etc/selinux/config
They also mention using getenforce as well as sestatus to check the status of selinux.

Success! Upon rebooting after changing /etc/selinux/config I see

SELinux status:                 disabled

Time to update the system

yum -y update
yum groupinstall core
yum groupinstall base

I'll be back in an hour or so after this is done.

Why are you installing a compiler? What are you going to compile?

Dashrender

Because the instructions tell me to...

There are several make commands in these setup instructions... is that compiling?

Dashrender

Check the status of iptables and disable them for now to make setup easier. (not my idea, the instructions idea).

chkconfig iptables --list
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off

It was already off (seems odd, but must be the default for C@C)

SQL setup time

chkconfig --level 345 mysqld on
service mysqld start

Output

Initializing MySQL database:  WARNING: The host 'c1107372-7807.cloudatcost.com' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h c1107372-7807.cloudatcost.com password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!
