centos下yum安装RabbitMQ［最顺利的一次］

需要的软件:epel-release-5-4.noarch.rpm(fedora源)
1.安装前准备
wget ftp://fr2.rpmfind.net/linux/epel/5/ppc/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
wget -P /etc/yum.repos.d/ http://repos.fedorapeople.org/repos/peter/erlang/epel-erlang.repo
yum clean all
yum -y install erlang

2.安装rabbitmq
rpm –import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
wget http://www.rabbitmq.com/releases/rabbitmq-server/v2.8.5/rabbitmq-server-2.8.5-1.noarch.rpm
rpm -ivh rabbitmq-server-2.8.5-1.noarch.rpm

3.启动rabbitmq并设置开机启动
chkconfig rabbitmq-server on
/sbin/service rabbitmq-server start

如果启动报错

Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}rabbitmq-server.

查看日志文件：

cat /var/log/rabbitmq/startup_logActivating RabbitMQ plugins ...ERROR: Could not delete dir /var/lib/rabbitmq/mnesia/rabbit@centhost-plugins-expand ({cannot_delete,                                                                                      "/var/lib/rabbitmq/mnesia/rabbit@centhost-plugins-expand/rabbitmq_management_agent-2.8.5/ebin/rabbit_mgmt_external_stats.beam",                                                                                      eacces})

发现没权限删除

/var/lib/rabbitmq/mnesia/

文件夹下内容，修改了相应权限，重新启动，成功。

4.检查rabbitmq是否启动
ps aux|grep rabbitmq
