Linux系統集羣架構線上項目配置實戰（三）

               

寫在前面

  前面介紹了分發文件管理、前端反向代理與管理後臺服務器的配置操做，今天介紹下前端負載與APP服務器（用戶與商家）、官網、FTP服務器的配置操做

01前端負載均衡配置

安裝所需的依賴包

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

編譯安裝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文件後增長下面的配置

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後端APP服務器配置

後端APP服務器JAVA環境安裝配置

[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)

後端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

-------------此處省略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" />

#增長上述站點目錄

[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)

另一臺用戶APP 服務器按上述的配置進行

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

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

商家APP環境配置請參考上面的配置

[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

接下來測試下負載均衡

前端負載均衡測試

[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

瀏覽器訪問測試

本地瀏覽器測試須要配置hosts文件

10.0.0.1 app.mingongge.com

10.0.0.1 sjapp.mingongge.com

03官網與圖片服務器配置

基本的架構也是同樣使用反向代理，爲了後期總體架構擴展

Nginx FTP的安裝就再也不描述了，太簡單了，扯多了累

前面反向代理配置以下

[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;

}

}

後端WEB服務器配置

[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這塊的配置實際上是就是管理後臺經過應用程序上傳圖片，前面用戶經過nginx能訪問到正確的頁面便可，因爲線下測試環境，不可能拿生產代碼來作實驗，所以管理後臺上傳圖片沒法模擬，過程就是後臺上傳圖片是經過FTP的功能上傳到指定的目錄，而後前端經過nginx來調用這個圖片去顯示

所以就配置下訪問圖片便可

[root@centos conf]# cd extra/

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

server {

   listen       88;

    server_name  localhost;

 location / {

    root   /www/ftp;

      }

上傳圖片進行測試

經過前端反向代理直接訪問域名來讀取圖，來實現應用程序調用圖片的功能在其它前臺頁面展現的功能

發現也是能夠正常訪問的
