• 集群架构(3)


    写在前面

      前面介绍了分发文件管理、前端反向代理与管理后台服务器的配置操作,今天介绍下前端负载与APP服务器(用户与商家)、官网、FTP服务器的配置操作

     

    01前端负载均衡配置

    安装所需的依赖包

    yum install pcre-devel zlib-devle openssl-devel gcc-c++ –y



    编译安装nginx

    cd /download/tools/

    wget http://nginx.org/download/nginx-1.12.1.tar.gz

    tar zxf nginx-1.12.1.tar.gz

    cd nginx-1.12.1

    ./configure --prefix=/app/nginx-1.12.1

    make && make install

    [root@centos ~]# cd /app/

    [root@centos app]# ln -s nginx-1.12.1 nginx

    [root@centos ~]# cd /app/nginx/conf/

    [root@centos conf]# mkdir extra

    [root@centos conf]# cp nginx.conf nginx.conf.bak

    在nginx.conf文件后增加下面的配置

    include extra/*.conf;



    [root@centos conf]# cd extra/

      oot@centos extra]# vim user.app.conf

    #

    # HTTPS server configuration

    #

    upstream userapp {

          server 10.0.0.4:8080;

          server 10.0.0.4:8081;

    }

    server {

        listen       80;

        server_name app.mingongge.com;

        location / {

            proxy_pass http://userapp;

            proxy_connect_timeout 600;

            proxy_read_timeout 600;

            proxy_send_timeout 600;

     

    }

    [root@centos conf]# cd extra/

    [root@centos conf]# vim sj.app.conf

    #

    # HTTPS server configuration

    #

    upstream sjapp {

          server 10.0.0.5:8080;

          server 10.0.0.5:8081;

    }

     

    server {

        listen       80;

        server_name sjapp.mingongge.com;

        location / {

            proxy_pass http://sjapp;

            proxy_connect_timeout 600;

            proxy_read_timeout 600;

            proxy_send_timeout 600;

    }

    }

     

    02后端APP服务器配置

    后端APP服务器JAVA环境安装配置

    [root@centos tools]# ll

    total 181168

    -rw-r--r-- 1 root root 185515842 Sep 20 15:52 jdk-8u144-linux-x64.tar.gz

    [root@centos tools]# tar zxf jdk-8u144-linux-x64.tar.gz -C /usr/local/

    [root@centos tools]# ln -s /usr/local/jdk1.8.0_144 /usr/local/jdk

    [root@centos tools]# cat >>/etc/profile<<EOF

    export JAVA_HOME=/usr/local/jdk

    export CLASSPATH=.CLASSPATH:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

    export PATH=$JAVA_HOME/bin:$PATH

    EOF

    [root@centos tools]# tail -3 /etc/profile

    export JAVA_HOME=/usr/local/jdk

    export CLASSPATH=.CLASSPATH:/lib/dt.jar:/lib/tools.jar

    export PATH=$JAVA_HOME/bin:$PATH

    [root@centos tools]# source /etc/profile

    [root@centos tools]# java -version

    java version "1.8.0_144"

    Java(TM) SE Runtime Environment (build 1.8.0_144-b01)

    Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

     

    后端tomcat 配置

    wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.5.20/bin/apache-tomcat-8.5.20.tar.gz

    [root@centos tools]# tar zxf apache-tomcat-8.5.20.tar.gz -C /usr/local/

    [root@centos tools]# ln -s /usr/local/apache-tomcat-8.5.20 /usr/local/tomcat

    [root@centos tools]# cd /usr/local/apache-tomcat-8.5.20/conf/

    [root@centos conf]# vim server.xml

    -------------此处省略N行--------------

    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

       prefix="localhost_access_log" suffix=".txt"

       pattern="%h %l %u %t &quot;%r&quot; %s %b" />

    <Context path="" docBase="/www/userapp" debug="0" reloadable="true" crossContext="true" />

    #增加上述站点目录

     

    [root@centos conf]# mkdir /www/userapp -p

    echo "this is the frist userapp server" >/www/userapp/index.html

    [root@centos conf]# ../bin/startup.sh

    Using CATALINA_BASE:   /usr/local/apache-tomcat-8.5.20

    Using CATALINA_HOME:   /usr/local/apache-tomcat-8.5.20

    Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.5.20/temp

    Using JRE_HOME:  /usr/local/jdk

    Using CLASSPATH: /usr/local/apache-tomcat-8.5.20/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.20/bin/tomcat-juli.jar

    Tomcat started.

    [root@centos conf]# lsof -i :8080

    COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

    java 1587 root 48u IPv6 18137 0t0 TCP *:webcache (LISTEN)

    另外一台用户APP 服务器按上述的配置进行

    [root@centos conf]# mkdir /www/userapp -p

    echo "this is the second userapp ">/www/userapp/index.html

                           

    商家APP环境配置请参考上面的配置

    [root@centos conf]# mkdir /www/sjapp -p

    echo "this is the frist sjapp ">/www/userapp/index.html

    echo "this is the second sjapp ">/www/userapp/index.html

    接下来测试下负载均衡

    前端负载均衡测试

    [root@centos conf]# curl http://10.0.0.1

    this is the userapp server

    [root@centos conf]# curl http://10.0.0.1

    this is the second userapp

    [root@centos conf]# curl http://app.mingongge.com

    this is the userapp server

    [root@centos conf]# curl http://app.mingongge.com

    this is the second userapp

    [root@centos extra]# curl http://sjapp.mingongge.com

    this is the first sjapp server

    [root@centos extra]# curl http://sjapp.mingongge.com

    this is the second sjapp

    浏览器访问测试

    本地浏览器测试需要配置hosts文件

    10.0.0.1 app.mingongge.com

    10.0.0.1 sjapp.mingongge.com

     

     

    03官网与图片服务器配置

    基本的架构也是一样使用反向代理,为了后期整体架构扩展

    Nginx FTP的安装就不再描述了,太简单了,扯多了累

    前面反向代理配置如下

    [root@centos extra]# vim web.mingongge.conf

    #

    # HTTPS server configuration

    #

     

    server {

        listen       80;

        server_name www.mingongge.com;

        location / {

            proxy_pass http://10.0.0.8;

            proxy_connect_timeout 600;

            proxy_read_timeout 600;

            proxy_send_timeout 600;

     

    }

    }

    [root@centos extra]# vim ftp.mingongge.com

    #

    # HTTPS server configuration

    #

    server {

        listen       80;

        server_name ftp.mingongge.com;

        location / {

            proxy_pass http://10.0.0.8:88;

            proxy_connect_timeout 600;

            proxy_read_timeout 600;

            proxy_send_timeout 600;

     

    }

    }

     

    后端WEB服务器配置

    [root@centos html]# vim index.html

    welcome to mingongge.s web stie!!!!!!!!!!!!!

    [root@centos ~]# /usr/local/nginx/sbin/nginx -t

    nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

    nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

    [root@centos ~]# /usr/local/nginx/sbin/nginx

    [root@centos ~]# curl 10.0.0.8

    welcome to mingongge.s web stie!!!!!!!!!!!!!

     

    FTP这块的配置其实是就是管理后台通过应用程序上传图片,前面用户通过nginx能访问到正确的页面即可,由于线下测试环境,不可能拿生产代码来做实验,因此管理后台上传图片无法模拟,过程就是后台上传图片是通过FTP的功能上传到指定的目录,然后前端通过nginx来调用这个图片去显示

    因此就配置下访问图片即可

    [root@centos conf]# cd extra/

    [root@centos extra]# vim ftp.mingongge.conf

    server {

       listen       88;

        server_name  localhost;

     

     location / {

        root   /www/ftp;

          }

    上传图片进行测试

     

    通过前端反向代理直接访问域名来读取图,来实现应用程序调用图片的功能在其它前台页面展示的功能

     

    发现也是可以正常访问的
