After a discussion with Radha, it looks like /etc/consul.d/consul.hcl
is not the config file we need.
The new path is /mnt/consul/consul/consul_config.json
sudo vim /mnt/consul/config/consul-config.json
Create an environment variable named CONSUL_CONFIG_DIR and set it to your Consul configuration directory path.
export CONSUL_CONFIG_DIR="/mnt/consul/config/"
Make sure the file is present:
ls -1 ${CONSUL_CONFIG_DIR}
Logs:
consul-config.json
Validate config file:
consul validate ${CONSUL_CONFIG_DIR}
Logs:
Config validation failed: performance.raft_multiplier cannot be 11. Must be between 1 and 10
Change performance.raft_multiplier to 5 (default)
We can see that different servers have different numbers in bootstrap_expect. Mine (server 2) has 5 and Berkeli's (server 1) has 2. We know that we will have 3 servers in total, so we will change this value to 3 as well.
consul validate ${CONSUL_CONFIG_DIR}
Logs:
The 'acl.tokens.master' field is deprecated. Use the 'acl.tokens.initial_management' field instead.
bootstrap_expect > 0: expecting 3 servers
Configuration is valid!
_The 'acl.tokens.master' field is deprecated. Use the 'acl.tokens.initialmanagement' field instead. looks suspicious but it doesn't look like an error for now so we will leave it.
Let's try to start consul:
consul agent -config-dir=${CONSUL_CONFIG_DIR}
Logs:
==> Failed to setup logging: open /var/log/consul-1673956064731056477.log: permission denied
This doesn't look right, my directory has to be /var/log/consul/ not /var/log/ Going back to consul-config.json and fixing "log_file":"/var/log/consul/"
But still same error, I need to give permissions to consul user and group:
sudo chown consul:consul /var/log/consul
sudo chmod u+w,g+w,o+w /var/log/consul/*
consul agent -config-dir=${CONSUL_CONFIG_DIR}
ls -al /var/log/consul/
Logs:
drwxr-xr-x 2 consul consul 44 Jan 17 12:26 .
drwxr-xr-x 8 root root 4096 Jan 17 12:04 ..
-rw-rw--w- 1 consul consul 111516 Jan 17 12:31 consul-1673958376420751130.log
now looks better

Write-up is on Berkeli's board
