准备工作

• 下载Erlang安装包：如果在线安装过慢，可以选择直接从官网https://www.erlang.org/downloads下载

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：

• •  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/[e-mail]

View Code

• • 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：wget https://dl.bintray.com/rabbitmq/community-plugins/3.6.x/rabbitmq_delayed_message_exchange/rabbitmq_delayed_message_exchange-20171215-3.6.x.zip
• 解压：unzip rabbitmq_delayed_message_exchange-20171215-3.6.x.zip（注意：如果unzip命令未找到，则需要安装unzip）
• 解压后得到文件：rabbitmq_delayed_message_exchange-20171215-3.6.x.ez
• 启用插件：rabbitmq-plugins enable rabbitmq_delayed_message_exchang
