Question

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

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

我收到如下信息：

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

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

sbin/rabbitmq-server

获取消息

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

我从源代码安装了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，我已经重新安装了以下配置的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

现在我收到了错误

/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[1]: Leaving directory `/var/tmp/otp_src_R16B03/lib'
make: *** [install.libs] Error 2

我无法解决此错误，任何建议.. 请注意我使用以root用户身份访问计算机

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

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使得EC Diffie-Hellman的速度提高2倍至4倍，但它有一些局限性。您可以在64位Intel计算机上使用它。另请参阅OpenSSL wiki上的Compilation and Installation | Configure Options。

另外，对于OpenSSL 1.0.2及更低版本，请确保make dclean;或make distclean用于OpenSSL 1.1.0及更高版本。否则，即使在更改选项后，某些旧配置仍然存在。

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