<!-- How to choose between replicas during distributed query processing.
|
|
random - choose random replica from set of replicas with minimum number of errors
|
|
nearest_hostname - from set of replicas with minimum number of errors, choose replica
|
|
with minumum number of different symbols between replica's hostname and local hostname
|
|
(Hamming distance).
|
|
in_order - first live replica is choosen in specified order.

<!-- Password could be specified in plaintext or in SHA256 (in hex format).
|
|
|
|
If you want to specify password in plaintext (not recommended), place it in 'password' element.
|
|
Example: <password>qwerty</password>.
|
|
Password could be empty.
|
|
|
|
If you want to specify SHA256, place it in 'password_sha256_hex' element.
|
|
Example: <password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>

|
How to generate decent password:
|
|
Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
|
|
In first line will be password and in second - corresponding SHA256.

<!-- List of networks with open access.
|
|
|
|
To open access from everywhere, specify:
|
|
<ip>::/0</ip>
|
|
|
|
To open access only from localhost, specify:
|
|
<ip>::1</ip>
|
|
<ip>127.0.0.1</ip>
|
|
|
|
Each element of list has one of the following forms:
|
|
<ip> IP-address or network mask. Examples: 213.180.204.3 or 10.0.0.1/8 or 10.0.0.1/255.255.255.0
|
|
2a02:6b8::3 or 2a02:6b8::3/64 or 2a02:6b8::3/ffff:ffff:ffff:ffff::.
|
|
<host> Hostname. Example: server01.yandex.ru.
|
|
To check access, DNS query is performed, and all received addresses compared to peer address.
|
|
<host_regexp> Regular expression for host names. Example, ^server\d\d-\d\d-\d\.yandex\.ru$
|
|
To check access, DNS PTR query is performed for peer address and then regexp is applied.
|
|
Then, for result of PTR query, another DNS query is performed and all received addresses compared to peer address.
|
|
Strongly recommended that regexp is ends with $
|
|
All results of DNS requests are cached till server restart.
