RabbitMQ安装常见错误

1.安装Erlang时openssl版本太低出错

---> Package erlang.x86_64 0:22.0.7-1.el7 will be installed
--> Processing Dependency: libcrypto.so.10(OPENSSL_1.0.2)(64bit) for package: erlang-22.0.7-1.el7.x86_64
--> Finished Dependency Resolution
Error: Package: erlang-22.0.7-1.el7.x86_64 (rabbitmq_erlang)

解决办法：升级openssl版本

下载安装包装上，重新安装erlang就好了

rpm -ivh openssl-libs-1.0.2k-16.el7.x86_64.rpm --force

2.启动rabbitmq时出错

chkconfig rabbitmq-server on
/sbin/service rabbitmq-server start
systemctl status rabbitmq-server

查看服务状态起不来

解决办法：原因可能是erlang和rabbitmq版本不匹配

一定要符合官方给出对用版本
