Instalação multinode Cassandra, Não é possível abrir o arquivo /var/log/cassandra/gc.log devido à Permissão negada

Question

Eu quero instalar o Cassandra em 4 nós remotos. Tudo funciona bem até eu chegar ao ponto quando eu verificar o status

nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens       Owns (effective)  Host ID                               Rack
UN  127.0.0.1  103.68 KiB  256          100.0%            4e03d80f-5972-4bc7-b36d-6e536ebfa808  rack1

Configurei corretamente o listen_address para 192.68.0.25 e sementes para 192.69.0.13

Eu tenho o mesmo no outro nó

Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens       Owns (effective)  Host ID                               Rack
UN  127.0.0.1  103.64 KiB  256          100.0%            c7ad74b0-9fa1-4068-a2f8-24e45523b731  rack1

Isto é o que eu tenho quando eu executo o cassandra a partir do shell de comando

    OpenJDK 64-Bit Server VM warning: Cannot open file /var/log/cassandra/gc.log due to Permission denied

    ^
Invalid yaml: file:/etc/cassandra/cassandra.yaml

Na verdade eu não tenho gc.log.Este é o conteúdo da pasta

/var/log/cassandra$ ls *.log
debug.log  system.log

e

/var/log$ ls -lia cassandra/
total 284

Answer 1

Certifique-se de que seu formato de arquivo / etc / hosts seja válido, como

root@my-cass1-1:~# cat /etc/hosts | egrep -v "^#|::"
127.0.0.1 localhost
192.168.xxx.13 my-cass1-1.int.xxxxxxxxx.tld my-cass1-1

E não há material localhost.localdomain.

em cassandra.yaml defina estas duas opções:

root@my-cass1-1:~# cat /etc/cassandra/cassandra.yaml | grep 192.168
          - seeds: "192.168.xxx.111,192.168.xxx.112,192.168.xxx.13,192.168.xxx.10"
listen_address: 192.168.xxx.13
broadcast_rpc_address: 192.168.xxx.13
