Ubuntu安装RabbitMQ及部署集群

2022-04-13 07:31:26 作者：互联网

由于为了学习RabbitMQ的使用,我在我服务器上安装了RabbitMQ.
目前服务器配置如下:

{
    vCPU: 2核,
    RAM : 3GB,
    ROM : 50G,
    磁盘节点: 192.168.2.25
    内存节点: 192.168.2.26,192.168.2.28
    HAProxy: 192.168.2.27 
}

更多的节点添加方式是一样的,这里就不再添加更多的了.
部署方案按照这个图来,Kafka那边暂时不用管.(图片参考自互联网)

安装RabbitMQ

要使用RabbitMQ首先肯定需要先在服务器上安装.
创建安装脚本

sudo nano ./installrabbitmq.sh

粘贴官网脚本内容

#!/usr/bin/sh

sudo apt-get install curl gnupg apt-transport-https -y

## Team RabbitMQ's main signing key
curl -1sLf "https://keys.openpgp.org/vks/v1/by-fingerprint/0A9AF2115F4687BD29803A206B73A36E6026DFCA" | sudo gpg --dearmor | sudo tee /usr/share/keyrings/com.rabbitmq.team.gpg > /dev/null
## Launchpad PPA that provides modern Erlang releases
curl -1sLf "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xf77f1eda57ebb1cc" | sudo gpg --dearmor | sudo tee /usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg > /dev/null
## PackageCloud RabbitMQ repository
curl -1sLf "https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey" | sudo gpg --dearmor | sudo tee /usr/share/keyrings/io.packagecloud.rabbitmq.gpg > /dev/null

## Add apt repositories maintained by Team RabbitMQ
sudo tee /etc/apt/sources.list.d/rabbitmq.list <<EOF
## Provides modern Erlang/OTP releases
##
## "bionic" as distribution name should work for any reasonably recent Ubuntu or Debian release.
## See the release to distribution mapping table in RabbitMQ doc guides to learn more.
deb [signed-by=/usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg] http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu bionic main
deb-src [signed-by=/usr/share/keyrings/net.launchpad.ppa.rabbitmq.erlang.gpg] http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu bionic main

## Provides RabbitMQ
##
## "bionic" as distribution name should work for any reasonably recent Ubuntu or Debian release.
## See the release to distribution mapping table in RabbitMQ doc guides to learn more.
deb [signed-by=/usr/share/keyrings/io.packagecloud.rabbitmq.gpg] https://packagecloud.io/rabbitmq/rabbitmq-server/ubuntu/ bionic main
deb-src [signed-by=/usr/share/keyrings/io.packagecloud.rabbitmq.gpg] https://packagecloud.io/rabbitmq/rabbitmq-server/ubuntu/ bionic main
EOF

## Update package indices
sudo apt-get update -y

## Install Erlang packages
sudo apt-get install -y erlang-base \
                        erlang-asn1 erlang-crypto erlang-eldap erlang-ftp erlang-inets \
                        erlang-mnesia erlang-os-mon erlang-parsetools erlang-public-key \
                        erlang-runtime-tools erlang-snmp erlang-ssl \
                        erlang-syntax-tools erlang-tftp erlang-tools erlang-xmerl

## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

赋予脚本执行权限

sudo chmod 755 ./installrabbitmq.sh

执行安装脚本安装RabbitMQ

./installrabbitmq.sh

安装完成后,再执行相关命令启动,以及其他常用命令

# 启动 rabbitmq 服务
sudo service rabbitmq-server start
# 关闭 rabbitmq 服务
sudo service rabbitmq-server stop
# 重启 rabbitmq 服务
sudo service rabbitmq-server restart
# 查看 rabbitmq 状态
sudo service rabbitmq-server status

另一台服务器也使用该命令安装RabbitMQ.
注意,启动RabbitMQ之后要启动管理服务插件,否则15672管理页面无法登录

# 启用 rabbitmq_manager
sudo rabbitmq-plugins enable rabbitmq_management

由于guest用户默认只能在localhost登录，所以我们需要创建一个新的用户.

##设置账号密码
joe@rabbitmq-01:~$ sudo rabbitmqctl add_user admin 123456
Adding user "admin" ...
joe@rabbitmq-01:~$ sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...
joe@rabbitmq-01:~$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...

到这里我们安装就完成了,并且可以通过15672端口访问到管理页面,并使用admin账户进行登录.

添加集群

RabbitMQ集群之间通信确认是否可以通信,使用的是cookie,所以需要保证所有节点的cookie文件中的值一样.
由于我们没有开通Ubuntu系统的root账户,所以我们先通过scp命令将25节点的cookie文件发送到用户目录.

sudo scp /var/lib/rabbitmq/.erlang.cookie joe@192.168.2.26:/home/joe/
sudo scp /var/lib/rabbitmq/.erlang.cookie joe@192.168.2.28:/home/joe/

发送成功后,登入到26,28服务器将该cookie文件覆盖到原安装的默认cookie文件

sudo mv ./.erlang.cookie /var/lib/rabbitmq/.erlang.cookie

完成后可以通过cat命令查看两个cookie是否一致.
注意,由于我们是由joe账户操作的文件,所以文件所有者发生了变化.导致RabbitMQ无法读取.所以这里还得改一下文件的所有者.

sudo chown rabbitmq /var/lib/rabbitmq/.erlang.cookie

然后配置各个节点的hosts文件.使其对应内容一致.

sudo nano /etc/hosts
# 根据自己的实际情况,加入如下信息
192.168.2.25 rabbitmq-01
192.168.2.26 rabbitmq-02
192.168.2.28 rabbitmq-03

调整好后逐个节点执行

sudo rabbitmq-server -detached

停止26,28节点的RabbitMQ服务.

# 停止服务
sudo rabbitmqctl stop_app
# 重置服务
sudo rabbitmqctl reset
# 加入时候设置节点为内存节点(默认加入的为磁盘节点)
sudo rabbitmqctl join_cluster rabbit@rabbitmq-01 --ram
#也通过下面方式修改的节点的类型,使用该命令前需要先停止当前节点.
sudo rabbitmqctl change_cluster_node_type disc | ram

搞好了后,即可通过管理页面查看

安装haproxy

首先我们根据官方地址来查看自己所属版本的命令,这里我是用的Ubuntu 20.04,所以执行如下命令,来安装haproxy

sudo apt-get install --no-install-recommends software-properties-common
sudo add-apt-repository ppa:vbernat/haproxy-2.5
sudo apt-get install haproxy=2.5.\*

等待数秒安装成功后,即可使用命令验证是否安装成功

sudo haproxy -v

若是能够输出相应的信息表示安装成功.

HAProxy version 2.5.5-1ppa1~focal 2022/03/14 - https://haproxy.org/
Status: stable branch - will stop receiving fixes around Q1 2023.
Known bugs: http://www.haproxy.org/bugs/bugs-2.5.5.html
Running on: Linux 5.4.0-107-generic #121-Ubuntu SMP Thu Mar 24 16:04:27 UTC 2022 x86_64

接下来编辑haproxy配置信息

sudo nano /etc/haproxy/haproxy.cfg

在配置文件中加入如下信息

#绑定配置
listen rabbitmq_cluster
        bind 0.0.0.0:5672
        #配置TCP模式
        mode tcp
        #加权轮询
        balance roundrobin
        #RabbitMQ集群节点配置,其中ip1~ip(n)为RabbitMQ集群节点ip地址
        server rabbitmq-02 192.168.2.26:5672 check inter 5000 rise 2 fall 3 weight 1
        server rabbitmq-03 192.168.2.28:5672 check inter 5000 rise 2 fall 3 weight 1

#haproxy监控页面地址
listen monitor
        bind 0.0.0.0:8100
        mode http
        option httplog
        stats enable
        stats uri /stats
        stats refresh 5s

最终该文件看起来是如下样子

global
        log /dev/log    local0
        log /dev/log    local1 notice
        chroot /var/lib/haproxy
        stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
        stats timeout 30s
        user haproxy
        group haproxy
        daemon

        ca-base /etc/ssl/certs
        crt-base /etc/ssl/private

        option  dontlognull
        timeout connect 5000
        timeout client  50000

        errorfile 400 /etc/haproxy/errors/400.http

        errorfile 503 /etc/haproxy/errors/503.http
        errorfile 504 /etc/haproxy/errors/504.http

#绑定配置
listen rabbitmq_cluster
        bind 0.0.0.0:5672
        #配置TCP模式
        mode tcp
        #加权轮询
        balance roundrobin
        #RabbitMQ集群节点配置,其中ip1~ip(n)为RabbitMQ集群节点ip地址
        server rabbitmq-02 192.168.2.26:5672 check inter 5000 rise 2 fall 3 weight 1
        server rabbitmq-03 192.168.2.28:5672 check inter 5000 rise 2 fall 3 weight 1

#haproxy监控页面地址
listen monitor
        bind 0.0.0.0:8100
        mode http
        option httplog
        stats enable
        stats uri /stats
        stats refresh 5s
        # 添加验证
        stats auth admin:123456

接下来启动haproxy服务,以及常用命令

# 启动服务
sudo systemctl start haproxy
# 查看状态
sudo systemctl status haproxy
# 重启服务
sudo systemctl restart haproxy
# 停止服务
sudo systemctl stop haproxy

通过查看服务状态确认无异常后,即可将haproxy服务加入开机自启

sudo systemctl enable haproxy

在一切都完成后,我们就可以登录配置的页面查看状态, http://192.168.2.27:8100/stats 由于我们配置了登录验证,输入刚才配置的账号密码(admin:123456)就可以进入页面了
