准备工作

wget http://erlang.org/download/otp_src_22.0-rc2.tar.gz
  • 下载rabbitmq-server安装包 
wget wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-3.8.2-1.el7.noarch.rpm

安装Erlang

  • 安装依赖类库：
    • yum -y install gcc-c++
    • yum -y install ncurses-devel
    • yum -y install openssl-devel
    • yum -y install unixODBC-devel
  • 创建目录（安装指定目录）：mkdir /usr/local/erlang
  • 打开目录 cd otp_src_22.2/
  • 安装至指定目录： ./configure --prefix=/usr/local/erlang --without-Javac
  • make && make install
  • 编译&安装完成以后配置Erlang环境变量：vim  /etc/profile
    • 追加环境变量到文件末尾：export PATH=$PATH:/usr/local/erlang/bin
    • source /etc/profile

安装RabbitMQ

  • 加载源：rpm -ivh --nodeps rabbitmq-server-3.8.2-1.el7.noarch.rpm
  • 如果linux的防火墙开启时，还需执行以下操作
    • firewall-cmd --zone=public --add-port=15672/tcp --permanent
    • firewall-cmd --zone=public --add-port=5672/tcp --permanent
    • firewall-cmd --reload
  • 启动：
    • rabbitmq-plugins enable rabbitmq_management
    • rabbitmq-server
  • 后台启动：rabbitmq-server -detached
  • 创建登录账号、密码：rabbitmqctl add_user [账号] [密码]
  • 授管理员权限：rabbitmqctl set_user_tags [账号] administrator
  • 授权用户到虚拟机（/）：rabbitmqctl set_permissions -p / [账号] '.*' '.*' '.*'
  • 配置开机自启动：
    • 添加自启动脚本：
    • 在/etc/init.d目录下新建一个rabbitmq-server文件，内容如下：　
#!/bin/sh
#
# rabbitmq-server RabbitMQ broker

    •  根据实际情况修改上面内容中
# 增加了Erlang环境路径
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/erlang/bin

# 服务脚本
DAEMON=/server/rabbitmq/sbin/${NAME}

CONTROL=/server/rabbitmq/sbin/rabbitmqctl

DESC=rabbitmq-server

USER=root

# 日志目录
INIT_LOG_DIR=/data/soft/rabbitmq_server-3.7.9/var/log/rabbitmq     

# pid文件，查找命令命令：find / -name rabbit*.pid                                       
PID_FILE=/var/lib/rabbitmq/mnesia/rabbit@linux-dev.pid

      • 设置执行权限，命令：chmod a+x /etc/init.d/rabbitmq-server
    添加开机启动项：
    • 添加命令：chkconfig --add /etc/init.d/rabbitmq-server
    • 查看启动项，命令：chkconfig --list
    • 需要设置rabbitmq-server启动命令：chkconfig rabbitmq-server on
    • 关闭命令为：chkconfig rabbitmq-server off
    • 删除命令为：chkconfig --del rabbitmq-server
  • 执行命令reboot，重启服务器即可验证nginx开机启动

安装 RabbitMQ延迟队列插件

　　在正常项目开发中，我们常常会遇到延迟消费的需求；所以我们在安装完RabbitMQ服务后，还需要安装对应延迟队列的插件，以方便满足业务需求。

  • 下载插件，注意要下载至你rabbitmq服务器的plugins目录下，例如：/usr/lib/rabbitmq/plugins
wget https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v3.8.0/rabbitmq_delayed_message_exchange-3.8.0.ez
  • 解压后得到文件：rabbitmq_delayed_message_exchange-20171215-3.8.0.ez
  • 拷贝文件到指定目录：
cp rabbitmq_delayed_message_exchange-3.8.0.ez /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.2/plugins/
  • 启用插件：rabbitmq-plugins enable rabbitmq_delayed_message_exchang
