The previous code enumerates lists both listening and connected sockets. The output of listening (-l) is enough for the intended purpose. Optimizing this. Further on, it matches on the first socket which in my case was mysqlx.sock which leads later to a protocol error. More specific search string resolves this. As on this situation: # netstat -axn | grep mysql unix 2 [ ACC ] STREAM LISTENING 1934165 /var/run/mysqld/mysqlx.sock unix 2 [ ACC ] STREAM LISTENING 1934169 /var/run/mysqld/mysqld.sock unix 3 [ ] STREAM CONNECTED 1934197 /var/run/mysqld/mysqld.sock [...] we had # netstat -axn | grep -m1 mysq unix 2 [ ACC ] STREAM LISTENING 1934165 /var/run/mysqld/mysqlx.sock and error ERROR 2007 (HY000): Protocol mismatch; server version = 11, client version = 10 After the fix it finds the right socket: # netstat -lxn | grep -m1 mysqld.sock unix 2 [ ACC ] STREAM LISTENING 1934169 /var/run/mysqld/mysqld.sock

As on this situation:
netstat -axn | grep mysql
unix 2 [ ACC ] STREAM LISTENING 1934165 /var/run/mysqld/mysqlx.sock
unix 2 [ ACC ] STREAM LISTENING 1934169 /var/run/mysqld/mysqld.sock
unix 3 [ ] STREAM CONNECTED 1934197 /var/run/mysqld/mysqld.sock
[...]
we had
netstat -axn | grep -m1 mysq
unix 2 [ ACC ] STREAM LISTENING 1934165 /var/run/mysqld/mysqlx.sock
and error
ERROR 2007 (HY000): Protocol mismatch; server version = 11, client version = 10
After the fix it finds the right socket:
netstat -lxn | grep -m1 mysqld.sock
unix 2 [ ACC ] STREAM LISTENING 1934169 /var/run/mysqld/mysqld.sock
