>[info] erlang 安裝 * **方式一：** ``` // 創建 rabbitmq 目錄 mkdir -p /usr/local/rabbitmq && cd /usr/local/rabbitmq // erlang 下載 https://packagecloud.io/rabbitmq/erlang/packages/el/7/erlang-23.2.7-2.el7.x86_64.rpm // 上傳 rz // 安裝 rpm -ivh erlang-23.2.7-2.el7.x86_64.rpm // 查看版本 erl -v ``` * **方式二：** 1. 新增文件 /etc/yum.repos.d/rabbitmq_erlang.repo，在文件里面新增下面內容并保存： ``` [rabbitmq_erlang] name=rabbitmq_erlang baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/$basearch repo_gpgcheck=1 gpgcheck=1 enabled=1 # PackageCloud's repository key and RabbitMQ package signing key gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300 [rabbitmq_erlang-source] name=rabbitmq_erlang-source baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/SRPMS repo_gpgcheck=1 gpgcheck=0 enabled=1 # PackageCloud's repository key and RabbitMQ package signing key gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300 ``` 2. 在centos控制臺輸入 ``` yum install -y erlang ``` ***** >[info] RabbitMQ 安裝啟動 1. 下載 rpm 包 ``` // 安裝需要的擴展 yum install -y socat wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.1/rabbitmq-server-3.8.1-1.el7.noarch.rpm ``` 2. 導入密鑰（如 yum install -y erlang 沒報 密鑰錯誤 即可跳過這一步） ``` rpm -import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc ``` 3. 安裝 rpm 包 ``` yum install -y rabbitmq-server-3.8.1-1.el7.noarch.rpm ``` 4. 啟動 rabbitmq ``` rabbitmq-server start ``` 4.1 加入開機啟動： ``` chkconfig rabbitmq-server on ``` 5. 查看 rabbitmq 的狀態 ``` rabbitmqctl status ``` 6. 啟用web管理插件，這樣子才能支持瀏覽器訪問rabbitmq ``` rabbitmq-plugins enable rabbitmq_management ``` 7. 設置操作系統字符集utf-8 ``` vim /etc/profile 文件末尾加上: export LC_ALL=en_US.UTF-8 然后執行： source /etc/profile ``` 8. 增加遠程訪問web管理臺用戶及授權 ``` # 增加test用戶，密碼為123456 rabbitmqctl add_user test 123456 # 添加test角色為 administrator rabbitmqctl set_user_tags test administrator # 給test用戶授權 rabbitmqctl set_permissions -p "/" test ".*" ".*" ".*" # 查看用戶是否已添加 rabbitmqctl list_users ``` 9. 輸入 ip:15672 進行訪問  **注：** 關閉防火墻，服務器添加 15672 端口 ``` systemctl stop firewalld systemctl disable firewalld ``` *****
