我在 Ubuntu 21.10 上使用bind9
。在旧版本下bind9
,一切正常:
$ named -v
BIND 9.16.1-Ubuntu (Stable Release) <id:[censored]>
然而,当我升级bind9
到新版本时9.16.15-Ubuntu
,我开始遇到问题:
$ sudo /etc/init.d/bind9 status
× named.service - BIND Domain Name Server
Loaded: loaded (/lib/systemd/system/named.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Wed 2021-10-20 11:03:30 CEST; 5min ago

运行 plainnamed
会出现以下错误:
$ named
named: symbol lookup error: /usr/lib/x86_64-linux-gnu/libdns-9.16.15-Ubuntu.so: undefined symbol: EVP_PKEY_new_raw_public_key
这个错误在 Google 上没有搜索结果,但是符号的名称似乎与 OpenSSL 有关,因此我附上了我的版本:
$ openssl version
OpenSSL 1.1.1l 24 Aug 2021 (Library: OpenSSL 1.1.1a 20 Nov 2018)
我该如何修复该问题?
答案1
事实证明,问题在于 OpenSSL 链接到了不一致的库。我安装了正确的库,但尚未删除错误的库。
删除这些库并ldconfig
随后运行解决了我的问题:
sudo rm /lib/x86_64-linux-gnu/libssl.so.1.1
sudo rm /lib/x86_64-linux-gnu/libcrypto.so.1.1
sudo ldconfig
