我正在尝试在 FreeBSD 11.2 Jail 上设置 MariaDB 10.2 服务器。
服务器正在运行,并能很好地通过 IPv4 接受远程连接。根据sockstat
,它还应该在 IPv6 上进行监听:
db# sockstat | grep 3306
mysql mysqld 17516 177 tcp46 *:3306 *:*
这确实是我想要的,因此我的 my.cnf 是:
db# cat my.cnf | grep -vE "^#"
[client]
port������������= 3306
socket����������= /tmp/mysql.sock
[mysqld]
port������������= 3306
bind-address����= ::
socket����������= /tmp/mysql.sock
skip-external-locking
key_buffer_size = 16K
max_allowed_packet = 1M
table_open_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 240K
server-id�������= 1
innodb_buffer_pool_size = 1G
innodb_log_file_size = 256M
innodb_log_buffer_size = 16M
[mysqldump]

max_allowed_packet = 16M
[mysql]

[myisamchk]
key_buffer_size = 8M
sort_buffer_size = 8M

interactive-timeout
但是,当我尝试通过 IPv6 连接它时,我的请求超时:
db# telnet db.local 3306
Trying fd0b:9867:5eb1::3306...
telnet: connect to address fd0b:9867:5eb1::3306: Operation timed out
telnet: Unable to connect to remote host
db# telnet ::1 3306
Trying ::1...
telnet: connect to address ::1: Operation timed out
telnet: Unable to connect to remote host
通过 IPv4,它不会:
db# telnet 10.0.0.10 3306
Trying 10.0.0.10...
Connected to db.burnus.net.
Escape character is '^]'.

5.5.5-10.2.22-MariaDB>8vmB=LG)M'zTti5g)3emysql_native_password^CConnection closed by foreign host.
db# telnet 127.0.0.1 3306
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Y
5.5.5-10.2.22-MariaDB?',Jme7}$Wm@70-/FO<~mysql_native_password^CConnection closed by foreign host.
当然,这两个地址都与监狱的网络接口相关联:
db# ifconfig em0 | grep inet
��������inet 10.0.0.10 netmask 0xffffffff broadcast 10.0.0.10
��������inet6 fd0b:9867:5eb1::3306 prefixlen 128
没有防火墙。
删除bind-address
my.cnf 中的 或将其更改为正确的 IPv6 地址或主机名也无济于事。你知道我可能做错了什么吗?

解决了。当然,这归结为路由错误。上面所述的所有内容均已正确设置,但主机将端口 3306 上的所有流量重定向到 Jail 的 IPv4 地址,这不知何故导致 MariaDB 服务不再信任它。
