Erlang 安装和"/usr/local/ssl/lib/libcrypto.a: could not read symbols: Bad value"

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，并遵循以下命令

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

我得到如下消息：

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

尽管我继续用make&进行安装，但在启动Rabbitmq服务器时，我收到以下错误

sbin/rabbitmq-server

正在获取消息

在探索了多种解决方案后，我明白了我需要安装最新的Openssl，并提供新安装的Openssl的路径。

我从源代码安装了Openssl，并安装了-fPIC

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，我用下面的配置重新安装了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[1]: Leaving directory `/var/tmp/otp_src_R16B03/lib'
make: *** [install.libs] Error 2

我无法解决这个错误，任何建议。。请注意，我正在使用访问机器作为根用户

/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选项来构建OpenSSL。对于一台64位的英特尔机器，可能会出现以下情况。

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，但也有一些局限性。您可以在64位Intel计算机上使用它。另请参阅OpenSSL wiki上的编译和安装|配置选项。

此外，请确保使用适用于OpenSSL 1.0.2及以下版本的make dclean；或适用于OpenSSL 1.1.0及以上版本的CCD_ 4。否则，即使在更改了选项之后，一些旧配置仍然存在。
