centos7部署Nginx和RabbitMQ

Nginx安装部署【简单】

简介

• Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。
• Nginx可以托管用户编写的WEB应用程序成为可访问的网页服务，同时也可以作为流量代理服务器，控制流量的中转。
• Nginx在WEB开发领域，基本上也是必备组件之一。

安装

• Nginx需要配置额外的yum仓库，才可以使用yum安装

安装Nginx的操作需要root身份

1. 安装yum依赖程序

   # root执行
   yum install -y yum-utils
   

2. 手动添加，nginx的yum仓库

   yum程序使用的仓库配置文件，存放在：/etc/yum.repo.d内。

   # root执行
   # 创建文件使用vim编辑
   vim /etc/yum.repos.d/nginx.repo
   # 填入如下内容并保存退出
   [nginx-stable]
   name=nginx stable repo
   baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
   gpgcheck=1
   enabled=1
   gpgkey=https://nginx.org/keys/nginx_signing.key
   module_hotfixes=true
   
   [nginx-mainline]
   name=nginx mainline repo
   baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=https://nginx.org/keys/nginx_signing.key
   module_hotfixes=true
   

   通过如上操作，手动添加nginx的yum仓库

3. 通过yum安装最新稳定版的nginx

   # root执行
   yum install -y nginx
   

4. 启动

   # nginx自动注册了systemctl系统服务
   systemctl start nginx		# 启动
   systemctl stop nginx		# 停止
   systemctl status nginx		# 运行状态
   systemctl enable nginx		# 开机自启
   systemctl disable nginx		# 关闭开机自启
   

5. 配置防火墙放行

   • nginx默认绑定80端口，需要关闭防火墙或放行80端口

   # 方式1（推荐），关闭防火墙
   systemctl stop firewalld		# 关闭
   systemctl disable firewalld		# 关闭开机自启
   
   # 方式2，放行80端口
   firewall-cmd --add-port=80/tcp --permanent		# 放行tcp规则下的80端口，永久生效
   firewall-cmd --reload							# 重新加载防火墙规则
   

6. 启动后,浏览器输入Linux服务器的IP地址或主机名即可访问

   • http://192.168.xxx.xxx

   ps：80端口是访问网站的默认端口，所以后面无需跟随端口号
   至此，Nginx安装配置完成。

RabbitMQ安装部署【简单】

简介

• RabbitMQ一款知名的开源消息队列系统，为企业提供消息的发布、订阅、点对点传输等消息服务。

• RabbitMQ在企业开发中十分常见，课程为大家演示快速搭建RabbitMQ环境。

安装

rabbitmq在yum仓库中的版本比较老，所以需要手动构建yum仓库

1. 准备yum仓库

   # root执行
   # 1. 准备gpgkey密钥
   rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
   rpm --import https://packagecloud.io/rabbitmq/erlang/gpgkey
   rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
   
   # 2. 准备仓库文件
   vim /etc/yum.repos.d/rabbitmq.repo
   # 填入如下内容
   ##
   ## Zero dependency Erlang
   ##
   
   [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://github.com/rabbitmq/signing-keys/releases/download/2.0/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://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
   sslverify=1
   sslcacert=/etc/pki/tls/certs/ca-bundle.crt
   metadata_expire=300
   
   ##
   ## RabbitMQ server
   ##
   
   [rabbitmq_server]
   name=rabbitmq_server
   baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/$basearch
   repo_gpgcheck=1
   gpgcheck=0
   enabled=1
   # PackageCloud's repository key and RabbitMQ package signing key
   gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
          https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
   sslverify=1
   sslcacert=/etc/pki/tls/certs/ca-bundle.crt
   metadata_expire=300
   
   [rabbitmq_server-source]
   name=rabbitmq_server-source
   baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/SRPMS
   repo_gpgcheck=1
   gpgcheck=0
   enabled=1
   gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
   sslverify=1
   sslcacert=/etc/pki/tls/certs/ca-bundle.crt
   metadata_expire=300
   

2. 安装RabbitMQ

   # root执行
   yum install erlang rabbitmq-server -y
   

3. 启动

   # root执行
   # 使用systemctl管控，服务名：rabbitmq-server
   systemctl start rabbitmq-server			# 启动
   systemctl stop rabbitmq-server			# 关闭
   systemctl enable rabbitmq-server		# 开机自启
   systemctl disable rabbitmq-server		# 关闭开机自启
   systemctl status rabbitmq-server		# 查看状态
   

4. 放行防火墙，RabbitMQ使用5672、15672、25672 3个端口

   # 方式1（推荐），关闭防火墙
   systemctl stop firewalld		# 关闭
   systemctl disable firewalld		# 关闭开机自启
   
   # 方式2，放行5672 25672端口
   firewall-cmd --add-port=5672/tcp --permanent		# 放行tcp规则下的5672端口，永久生效
   firewall-cmd --add-port=15672/tcp --permanent		# 放行tcp规则下的15672端口，永久生效
   firewall-cmd --add-port=25672/tcp --permanent		# 放行tcp规则下的25672端口，永久生效
   firewall-cmd --reload								# 重新加载防火墙规则
   

   # 启动有报错的信息但是，查看状态
   [root@yuan ~]# systemctl start rabbitmq-server
   Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.
   [root@yuan ~]# systemctl status rabbitmq-server
   ● rabbitmq-server.service - RabbitMQ broker

   10月 13 22:44:30 yuan systemd[1]: rabbitmq-server.service failed.
   

5. 启动RabbitMQ的WEB管理控制台

   rabbitmq-plugins enable rabbitmq_management
   

   # 停止RabbitMQ管理插件
   rabbitmq-plugins disable rabbitmq_management
   

6. 添加admin用户，并赋予权限

   rabbitmqctl add_user admin 'yuan66^'
   rabbitmqctl set_permissions -p "/" "admin" ".*" ".*" ".*"
   rabbitmqctl set_user_tags admin administrator
   

7. 浏览器打开管理控制台
