Error: \{undef, 日志 \[\{crypto,hash,XXXXXXXXXXXXX等错误rabbit

出现这种先看环境

正常情况是这样的。输入 crypto:start(). 会出现ok

解决办法重新编译erl 直接重新安装就能解决问题

安装openssl过程当中，若是直接运行./config是不会产生libcrypto.so动态库的，只有静态库。得从新执行./config shared命令并从新编译make && make install才会出来动态库

以后make clean Erlang的源码，从新编译并安装，以后在erlang中执行crypto:start().，回显ok就好。从新在rabbitmq中添加用户，成功，问题解决。
