MySQL Router daemon not listening any ports

Question

I installed the program as described here https://dev.mysql.com/doc/mysql-router/8.0/en/mysql-router-deploying-bootstrapping.html.

After installation, the service mysqlrouter was launched in the system. But this service does not listen any of the ports specified in the configuration file "/etc/mysqlrouter/mysqlrouter.conf".

Command lsof -i -P -n | grep LISTEN shows:

systemd-r 780 systemd-resolve 13u IPv4 17461 0t0 TCP 127.0.0.53:53 (LISTEN) 
sshd 1140 root 3u IPv4 20873 0t0 TCP *:22 (LISTEN) 
sshd 1140 root 4u IPv6 20890 0t0 TCP *:22 (LISTEN) 

As you can see, only port 22 is listening.

To make the mysqlrouter listen to the port which defined in config file, I have to start it as a new process, using command mysqlrouter -c /etc/mysqlrouter/mysqlrouter.conf &.

After that, mysqlrouter listening the port and all is OK.

This is looks like that the service does not load the configuration file /etc/mysqlrouter/mysqlrouter.conf during startup, and uses default (empty) configuration, which not listening anything.

Configuration file contents:

[routing:default]
bind_address=0.0.0.0
bind_port=3306
destinations=metadata-cache://personal/default?role=PRIMARY
routing_strategy=first-available
protocol=classic

How to make mysqlrouter daemon start working in accordance with the configuration file, and listen on the specified ports?

If I start mysqlrouter as a new process using command mysqlrouter -c /etc/mysqlrouter/mysqlrouter.conf & it works properly:

systemd-r  780 systemd-resolve   13u  IPv4  17461      0t0  TCP 127.0.0.53:53 (LISTEN)
sshd      1140            root    3u  IPv4  20873      0t0  TCP *:22 (LISTEN)
sshd      1140            root    4u  IPv6  20890      0t0  TCP *:22 (LISTEN)
main      3615            root    4u  IPv4  43469      0t0  TCP *:3306 (LISTEN)

Updated...

Command systemctl status mysqlrouter.service shows:

As I said, service works, but it still does not listening ports.

systemd-r  780 systemd-resolve   13u  IPv4  17461      0t0  TCP 127.0.0.53:53 (LISTEN)

Answer 1

Using this command is normal.

try this:

sudo mysqlrouter --user=mysqlrouter --bootstrap [email protected]:3306  --conf-use-sockets  --report-host localhost  --force

Answer 2

Use the following instead.

bind_address=127.0.0.1

I got the following:

netstat -ntlp
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      6117/mysqlrouter

Use dbhost: 127.0.0.1
