原因分析：apache2.x 和openssl1.0.x不兼容导致的
解决方法：安装openssl0.9.8e
安装步骤：
| 1 2 3 4 5 6 7 8 9 10 11 12 | # tar zxvf openssl-0.9.8e.tar.gz # cd openssl-0.9.8e # ./config shared zlib # make # make test # make install # mv /usr/bin/openssl /usr/bin/openssl.OFF # mv /usr/include/openssl /usr/include/openssl.OFF # rm -rf /usr/lib/libssl.so # ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl # ln -s /usr/local/ssl/include/openssl /usr/include/openssl # ln -sv /usr/local/ssl/lib/libssl.so.0.9.8 /usr/lib/libssl.so |
配置库文件搜索路径
| 1 2 | # echo "/usr/local/ssl/lib" >> /etc/ld.so.conf # ldconfig -v |
检测安装结果
| 1 | # openssl version |
OpenSSL 0.9.8e 23 Feb 2007
安装成功！
重新编译apache，编译时参数加上 --enable-ssl --with-ssl=/usr/local/ssl
问题解决。
