【RabbitMQ】安裝

RabbitMQ可以安裝在很多作業系統上，我的系統：

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.5.1804 (Core) 
[root@localhost ~]# 

安裝erlang

RabbitMQ依賴於erlang，所以在安裝RabbitMQ前，我們先安裝erlang，yum源參考：erlang yum（我使用Erlang 20.x on CentOS 7）

Erlang 20.x on CentOS 7：

# In /etc/yum.repos.d/rabbitmq-erlang.repo
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/20/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

[root@localhost ~]# vi /etc/yum.repos.d/rabbitmq-erlang.repo # 新增erlang repos，填入以上內容
[root@localhost ~]# yum update
[root@localhost ~]# yum install -y erlang

等待安裝完成即可

安裝其他依賴

除了erlang外，rabbitmq還依賴於“socat”，使用以下命令即可安裝完成

[root@localhost ~]# yum install -y socat

安裝rabbitmq

從rabbitmq-server-3.7.6-1.el7.noarch.rpm下載rabbitmq的rpm包

[root@localhost ~]# wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.6/rabbitmq-server-3.7.6-1.el7.noarch.rpm

[root@localhost ~]# rpm -ivh rabbitmq-server-3.7.6-1.el7.noarch.rpm

rabbitmq安裝完成

如果你是其他作業系統，請參考官網：Downloading and Installing RabbitMQ

啟動rabbitmq

[root@localhost ~]# systemctl start rabbitmq-server.service

[root@localhost ~]# systemctl status rabbitmq-server.service

[root@localhost ~]#

啟動成功之後，我們為了後續測試方便，先建立一個使用者

[root@localhost ~]# rabbitmqctl add_user <username> <password>
[root@localhost ~]# rabbitmqctl set_permissions -p / <username> ".*" ".*" ".*"

說明：

• rabbitmq預設建立了guest使用者，但只允許通過localhost訪問
• 每個使用者訪問rabbitmq都需要使用vhost（許可權控制）
• rabbitmq預設建立了/ vhost，需要給新建的使用者設定許可權，不然會報錯：no access to this vhost

防火牆

rabbitmq預設使用5672埠，如果rabbitmq不是安裝在本機，記得開放tcp/5672，centos 7開放tcp/5672的命令：

[root@localhost anys]# firewall-cmd --zone=public --add-port=5672/tcp --permanent
[root@localhost anys]# firewall-cmd --reload
