我已在 Ubuntu 12.04.4 LTS 上将 OpenSSL 更新为 1.0.1 g 版：
user@server# dpkg -l |grep openssl
ii openssl 1.0.1-4ubuntu5.12 Secure Socket Layer (SSL) binary and related cryptographic tools
ii python-openssl 0.12-1ubuntu2.1 Python wrapper around the OpenSSL library
问题：我也需要更新 Apache2 mod_ssl 吗？如果是，如何？
user@server# strings /usr/lib/apache2/modules/mod_ssl.so | grep -i "openssl"
OPENSSL_add_all_algorithms_noconf
OPENSSL_load_builtin_modules
OPENSSL_1.0.1
OPENSSL_1.0.0
SSLFIPS invalid, rebuild httpd and openssl compiled for FIPS
