[SOLVED] cassandra.service fail to start

hey everyone
i currently installed Apache Cassandra
first time i tried this:

sudo systemctl start cassandra.service

and it worked well!
and i logged into CQL shell by typing cqlsh in the terminal.

but now i cant start it anymore!
when i try to start it and then try to see it's status, i get this:

$ sudo systemctl start cassandra.service 
$ sudo systemctl status cassandra.service 
● cassandra.service - Cassandra NoSQL database

Do not bump: https://wiki.archlinux.org/index.php/Co … ct#Bumping

Have you tried launching the binary directly? Perhaps with a verbose or debug switch, if available.

Re: [SOLVED] cassandra.service fail to start

So I have just installed Cassandra for the first time and ran into similar issue.
When I opened /var/log/cassandra/system.log the last line there was

ERROR [main] 2017-04-22 16:01:24,710 CassandraDaemon.java:752 - Local host name unknown: java.net.UnknownHostException: hostname: hostname: Name or se
rvice not known

The simplest solution for me was to do:

printf "%s %s %s\n" ::1       $(hostname) $(hostname) >> /etc/hosts
printf "%s %s %s\n" 127.0.0.1 $(hostname) $(hostname) >> /etc/hosts

Hope this helps.

your answer fixed my problem. thanks a lot!
but!
i got another weird thing!
when i start cassandra.. and then trying to access CQL shell.. i get this

[~]$ cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

BUT when i try this again! it works fine

blackout [~]$ cqlsh
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 3.10 | CQL spec 3.4.4 | Native protocol v4]
Use HELP for help.
cqlsh> 

***** UPDATED *****
after couple of reboots.. it fixed. and i can access CQL shell at the first try
thanks my friend
