Erlang 安装和“/usr/local/ssl/lib/libcrypto.a：无法读取符号：错误值”

Question

我正在尝试在 Linux 机器 Red Hat Enterprise Linux Server 6.6 版上安装 RabbitMQ (3.6.1)。要安装 rabbitMQ ，首先我从源代码（otp_src_R16B03）安装了 Erlang R16B03 版本，然后按照以下命令进行操作

wget http://www.erlang.org/download/otp_src_R16B03.tar.gz
tar xvfz /usr/tmp/otp_src_R16B03.tar
cd otp_src_R16B03
LANG=C; export LANG
./configure --with-ssl=/usr/bin

我收到如下所示的消息：

*********************************************************************

虽然我继续使用 make & make install 但在启动 Rabbitmq 服务器时出现以下错误

sbin/rabbitmq-server

收到消息

在探索了多种解决方案后，我了解到我需要安装最新的 Openssl 并提供新安装的 openssl 的路径。

我从源安装 Openssl 并使用 -fPIC 安装

wget https://www.openssl.org/source/openssl-1.0.2.tar.gz
tar xvfz /usr/tmp/openssl-1.0.2.tar.gz
cd /usr/tmp/openssl-1.0.2
./config -fPIC
make 
make install 

现在新的 openssl 安装在 bin/local/ssl 位置，我已经使用以下配置重新安装了 Erlang

export PATH="/usr/local/ssl/bin:$PATH”
export CFLAGS=-fPIC
cd /usr/tmp/otp_src_RB1603
LANG=C; export LANG
./configure --with-ssl=/usr/local/bin
make
make install

现在我得到了错误

/usr/bin/ld: /usr/local/ssl/lib/libcrypto.a(rsaz_exp.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

make[1]: *** [release] Error 2

make: *** [install.libs] Error 2

我无法解决这个错误，任何建议.. 请注意，我正在以 root 用户身份使用访问机器

/usr/bin/ld: /usr/local/ssl/lib/libcrypto.a(rsaz_exp.o): relocation R_X86_64_32 against `.rodata'

您需要使用 shared 选项构建 OpenSSL。对于 64 位 Intel 机器，可能类似于以下内容。

wget https://www.openssl.org/source/openssl-1.1.0b.tar.gz
tar xzf openssl-1.1.0b.tar.gz
cd openssl-1.1.0b

./Configure no-ssl2 no-ssl3 shared enable-ec_nistp_64_gcc_128
...
make -j 8
...
make test
...
suod make install

enable-ec_nistp_64_gcc_128 使 EC Diffie-Hellman 的速度提高了 2 到 4 倍，但它有一些限制。您可以在 64 位 Intel 机器上使用它。另请参阅 OpenSSL wiki 上的 Compilation and Installation | Configure Options。

此外，对于 OpenSSL 1.0.2 及以下版本，请务必使用 make dclean；或 make distclean 用于 OpenSSL 1.1.0 及更高版本。否则，即使更改了选项，一些旧配置仍然存在。
