rabbitmq3.6.6安装，环境centos7

一，需求描述

在centos7上安装rabbitmq3.6.6

附上安装脚本，附上官网地址 http://www.rabbitmq.com/ ，从这上面可以下载rabbitmq-server-3.6.6-1.el7.noarch.rpm包。注意，运行脚本之前需要设置机器的主机名名添加主机名解析，不然rabbitmq会启动报错。详细内容可看第三条问题记录

#/bin/bash 
SRC_URI="https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_6_6/rabbitmq-server-3.6.6-1.el7.noarch.rpm"
PKG_NAME=`basename $SRC_URI`
DIR=`pwd`
DATE=`date +%Y%m%d%H%M%S`
 
yum install -y erlang.x86_64
yum install -y socat.x86_64
 
if [ ! -s $PKG_NAME ]; then
wget -c $SRC_URI
fi
rpm -ivh rabbitmq-server-3.6.6-1.el7.noarch.rpm
 
service rabbitmq-server start #启动
rabbitmqctl add_user admin adminpasswd #设置密码
rabbitmqctl set_user_tags admin administrator
rabbitmq-plugins enable rabbitmq_management
 
if ! cat /etc/rc.d/rc.local | grep 'service rabbitmq-server start' &> /dev/null;then
echo "service rabbitmq-server start" >> /etc/rc.d/rc.local
fi #加入开机启动
chmod +x /etc/rc.d/rc.local  #centos7里面默认这个文件没有执行权限

脚本使用方法：

将上面的内容copy下来保存为文件rabbitmq_install.sh，在机器上执行bash rabbitmq_install.sh即可

二，验证

访问rabbitmq的网址ip:15672

可以网页了，进行登录，大功告成！

三，问题记录

1，rabbitmq启动报错

Feb 20 18:30:09 test rabbitmqctl[822]: attempted to contact: [rabbit@test]

Feb 20 18:30:09 test rabbitmqctl[822]: rabbit@test:

Feb 20 18:30:09 test rabbitmqctl[822]: * unable to connect to epmd (port 4369) on test: address (cannot connect to host/port)

Feb 20 18:30:09 test rabbitmqctl[822]: current node details:

Feb 20 18:30:09 test rabbitmqctl[822]: - node name: 'rabbitmq-cli-76@test'

Feb 20 18:30:09 test rabbitmqctl[822]: - home dir: .

Feb 20 18:30:09 test rabbitmqctl[822]: - cookie hash:xxxxxxxxxxxxx==

Feb 20 18:30:09 test systemd[1]: Failed to start RabbitMQ broker.

Feb 20 18:30:09 test systemd[1]: Unit rabbitmq-server.service entered failed state.

Feb 20 18:30:09 test systemd[1]: rabbitmq-server.service failed.

解决：

在/etc/hosts里添加主机名解析

运行如下命令即可

sed -i s/"127.0.0.1 localhost"/"127.0.0.1 localhost `hostname`"/g /etc/hosts #解释：将/etc/hosts 里的127.0.0.1 localhos字段替换成127.0.0.1 localhost `本机主机名`

2，附上centos7查看所有已启动的服务的命令

systemctl list-units --type=service
