iRODs 4.1.6 on my CentOS

My First test with iRODS 4.1.6 on a CentOS 7

From : https://groups.google.com/forum/#!forum/irod-chat

I did :  chmod -R 755 /var/lib/irods

-- My Server files---

#rpm -qa postgre*

in the file :   /var/lib/pgsql/data/postgresql.conf
you need to change : listen_addresses = 'localhost'  to   listen_addresses = '*'

Also remember to add it to firewall-cmd with the option : --permanent
To fix this error open PostgreSQL client authentication configuration file /var/lib/pgsql/data/pg_hba.conf :
# vi /var/lib/pgsql/data/pg_hba.conf

This file controls: Which hosts are allowed to connect
How clients are authenticated which PostgreSQL user names they can use Which databases they can access

By default Postgresql uses IDENT-based authentication.
All you have to do is allow username and password based authentication for your network or webserver. 

IDENT will never allow you to login via -U and -W options. Append following to allow login via localhost only:

local all all trust
host all 127.0.0.1/32 trust
Save and close the file. Restart Postgresql!

Other usefull stuff: (systemD)
systemctl status postgresql.service
systemctl stop postgresql.service
systemctl start postgresql.service

Test your iRODS password with : iinit
Wrong password will give :
Enter your current iRODS password:
[-]     libnative.cpp:336:native_auth_client_response :  status [CAT_INVALID_AUTHENTICATION]  errno [] -- message [Call to rcAuthResponseFailed.]
 failed with error -826000 CAT_INVALID_AUTHENTICATION

Right password will give :
Enter your current iRODS password:

install postgresql93:  (NOT the latest one!!! )
rpm -iUvh http://yum.postgresql.org/9.3/redhat/rhel-latest-x86_64/pgdg-centos93-9.3-1.noarch.rpm; yum update
yum -y install postgresql93 postgresql93-server postgresql93-contrib postgresql93-libs postgresql93-odbc fuse-libs.x86_64 perl-JSON* python-jsonschema.noarch

Get the rpm from.... ftp://ftp.renci.org/pub/irods/releases/

Please Note : IDROP-web need : TomCat 7 or 8 (and Varnish???)

I'm still testing with Varnish vs. Apache Traffic Server as a Reverse Proxy

--My Setup:
Varnish : nano /etc/yum.repos.d/varnish.repo

---the file-------

[varnish-4.0]
name=Varnish 4.0 for Enterprise Linux

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-VARNISH
---------
yum install varnish varnish-libs varnish-libs-devel

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

nano /etc/varnish/varnish.params
Setup : DAEMON_OPTS="-a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m"

Please let me know how you did your CentOS 7 or RedHat ES 7
