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
       Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)

    1013 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
