EMQ安装与部属

1.下载EMQ安装包

访问EMQ官网下载地址:

$ https://www.emqx.cn/downloads/broker/v4.2.7/emqx-centos7-4.2.7-x86_64.rpm
#1.上传到指定的文件夹/usr/local/
#2.安装 
rpm -ivh openssl-libs-1.0.2k-21.el7_9.x86_64.rpm --force
rpm -ivh erlang-22.0.7-1.el7.x86_64.rpm
rpm -ivh emqx-centos7-4.2.7-x86_64.rpm
#3.运行
sudo emqx start
#关闭防火墙
systemctl disable firewalld
systemctl stop firewalld.service
#单节点的登录
192.168.86.162:18083
admin public

2.集群部署

机器名IP作用
emq1192.168.86.161代理机器
emq2192.168.86.162节点1
emq3192.168.86.163节点2
emq4192.168.86.164节点3
#手动添加节点配置方式
#编辑每个节点的配置文件
vim etc/emqx/emqx.conf
#修改各自节点名称呼  集群名@IP
cluster,name = emqx
node.name = emqx@192.168.86.162
#重新启动节点
#然后将附属节点添加到集群中去
#在192.168.86.162上
emqx_ctl cluster join emqx@192.168.86.163
#在164上
emqx_ctl cluster join emqx@192.168.86.162 
#或者
emqx_ctl cluster join emqx@192.168.86.162
# 自动添加节点的配置方式
## 修改节点名  #修改各自节点名称呼  集群名@IP
node.name = emqx@192.168.86.162

## 修改集群策略为static,无需手动添加节点了
cluster.discovery = static

## 所有集群节点	
cluster.static.seeds = emqx@192.168.86.162, emqx@192.168.86.163, @emqx192.168.86.164

## 为了获取 IP 地址,需要设置 proxy_protocol
listener.tcp.external.proxy_protocol = on
挂载机器的yum源
mkdir /mnt/cdrom
#挂载命令
mount /dev/sr0 /mnt/cdrom/
#编辑yum配置文件
cat >> /etc/yum.repos.d/CentOS-Media.repo <<EOF
#添加如下内容
[local]
name=local
baseurl=file:///mnt/cdrom
gpgcheck=0
enable=1
EOF
#将默认的yum源配置文件改名  使其失效
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.back

yum makecache

yum -y install haproxy

global
    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    # local2.*                       /var/log/haproxy.log
    #
    log         127.0.0.1 local2
