百万PV1网站架构

一.181 IP master服务器要联网配置:

1.安装带有nginx rpm软件包的源

[root@xa ~]# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.centos 默认仓库完成下面的安装

[root@xa ~]# yum install -y keepalived nginx

[root@xa ~]# vi /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

route_id NGINX_HA

}

vrrp_script nginx {

script "/opt/shell/nginx.sh"

interval 2

}

vrrp_instance VI_1 {

state MASTER

interface ens33

virtual_router_id 51

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

track_script {

nginx

}

virtual_ipaddress {

192.168.80.188

192.168.0.119

}

}

[root@xa ~]# mkdir /opt/shell

[root@xa ~]# vi /opt/shell/nginx.sh

[root@xa ~]# chmod +x /opt/shell/nginx.sh

3.配置nginx前端调度功能

vi /etc/nginx/nginx.conf

[root@xa ~]#  nginx -t -c /etc/nginx/nginx.conf //测试配置文件语法

二.80.182 IP backup服务器要联网配置:

[root@xb yum.repos.d]# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

yum install -y keepalived nginx

[root@xb yum.repos.d]# vi /etc/keepalived/keepalived.conf

mkdir /opt/shell

vi /opt/shell/nginx.sh

#!/bin/bash

k=`ps -ef | grep keepalived | grep -v grep | wc -l`

if [ $k -gt 0 ];then

/bin/systemctl start nginx.service

else

/bin/systemctl stop nginx.service

fi

chmod +x /opt/shell/nginx.sh

[root@xb yum.repos.d]# mkdir /opt/shell

[root@xb yum.repos.d]# vi /opt/shell/nginx.sh

[root@xb yum.repos.d]# chmod +x /opt/shell/nginx.sh

[root@xb yum.repos.d]# vi /etc/nginx/nginx.conf

[root@xb yum.repos.d]#  nginx -t -c /etc/nginx/nginx.conf

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

三、---------80.184安装web服务器---------

[root@xd ~]# tar xf apache-tomcat-8.5.23.tar.gz

[root@xd ~]# tar xf jdk-8u144-linux-x64.tar.gz

cp -rv jdk1.8.0_144/ /usr/local/java

[root@xd ~]# vi /etc/profile

[root@xd ~]# source /etc/profile

[root@xd ~]# 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)

[root@xd ~]# cp -r apache-tomcat-8.5.23 /usr/local/tomcat8

[root@xd ~]# ln -s /usr/local/tomcat8/bin/startup.sh /usr/bin/tomcatup

[root@xd ~]# ln -s /usr/local/tomcat8/bin/shutdown.sh /usr/bin/tomcatdown

[root@xd ~]# tomcatup

Using CATALINA_BASE:   /usr/local/tomcat8

Using CATALINA_HOME:   /usr/local/tomcat8

Using CATALINA_TMPDIR: /usr/local/tomcat8/temp

Using JRE_HOME:        /usr/local/java/jre

Using CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar

Tomcat started.

[root@xd ~]# netstat -anpt | grep 8080

tcp6       0      0 :::8080                 :::*                    LISTEN      1149/java

[root@xd ~]# vi /usr/local/tomcat8/webapps/ROOT/index.jsp

---------80.185安装web服务器---------

root@192.168.80.185

Last login: Thu May  3 05:27:47 2018 from 192.168.80.8

[root@xe ~]# tar xf apache-tomcat-8.5.23.tar.gz

[root@xe ~]# tar xf jdk-8u144-linux-x64.tar.gz

cp -rv jdk1.8.0_144/ /usr/local/java

vi /etc/profile

export JAVA_HOME=/usr/local/java

export JRE_HOME=/usr/local/java/jre

export PATH=$PATH:/usr/local/java/bin

export CLASSPATH=./:/usr/local/java/lib:/usr/local/java/jre/lib

[root@xe ~]# source /etc/profile

[root@xe ~]#

[root@xe ~]# 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)

[root@xe ~]# cp -r apache-tomcat-8.5.23 /usr/local/tomcat8

[root@xe ~]# ln -s /usr/local/tomcat8/bin/startup.sh /usr/bin/tomcatup

[root@xe ~]# ln -s /usr/local/tomcat8/bin/shutdown.sh /usr/bin/tomcatdown

[root@xe ~]# tomcatup

[root@xe ~]# netstat -anpt | grep 8080

tcp6       0      0 :::8080                 :::*                    LISTEN      1004/java

 输入调度器地址，也就是虚拟地址，测试两台节点的调度情况。

vi /usr/local/tomcat8/webapps/ROOT/index.jsp //修改默认网页内容 下行加

Server 185！！

 输入调度器地址，也就是虚拟地址，测试两台节点的调度情况。

vi server.xml //跳到行尾，在Host name下新增

四、mysql安装在master and backup服务器上

----使用7.4光盘自带仓库--在主从服务器做------

yum install -y mariadb-server mariadb

[root@xa ~]# systemctl start mariadb.service

[root@xa ~]# systemctl enable mariadb.service

Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

[root@xa ~]#

[root@xa ~]# netstat -anpt | grep 3306

tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      19566/mysqld

[root@xa ~]#

[root@xa ~]# mysql_secure_installation

----------导入数据库-----------

mysql -u root -p  < slsaledb-2014-4-10.sql

mysql -uroot -p

show databases;

GRANT all ON slsaledb.* TO 'root'@'%' IDENTIFIED BY '123456';

flush privileges;

五、----------------以下在两台tomcat节点web服务器配置----------------

[root@xd ~]# tar xf SLSaleSystem.tar.gz -C /usr/local/tomcat8/webapps/

[root@xd ~]# cd /usr/local/tomcat8/webapps/SLSaleSystem/WEB-INF/classes

[root@xd classes]#

[root@xd classes]# vi jdbc.properties

---------解决虚拟地址不能访问的问题------

cd /usr/local/tomcat8/webapps/SLSaleSystem/WEB-INF

vi web.xml

index.jsp //修改使用相对路径

cp pages/index.jsp /usr/local/tomcat8/webapps/SLSaleSystem/

 //输入虚拟地址测试，并且关闭主再测试

[root@xc WEB-INF]# tomcatdown

[root@xc WEB-INF]# tomcatup

六-------------在两台web服务器节点上-------------

[root@xd WEB-INF]# vi /usr/local/tomcat8/conf/server.xml

route add -net 224.0.0.0 netmask 240.0.0.0 dev ens33 //组播报错解决

netstat -gn

----------在两台节点上做测试页---------注意hosts文件中要有主机名---

vi /usr/local/tomcat8/webapps/SLSaleSystem/test.jsp

SessionID:<%=session.getId()%>

SessionPort:<%=request.getServerPort()%>

<%

out.println("This is Tomcate Server 192.168.80.184!");

%>

vi /usr/local/tomcat8/webapps/SLSaleSystem/WEB-INF/web.xml

tomcatdown

tomcatup

[root@xd WEB-INF]# netstat -anpt | grep 4000

tcp6       0      0 192.168.80.184:4000     :::*                    LISTEN      1323/java

----------在master服务器和backup服务器上做---------------------------

[root@xb ~]# yum install -y epel-release

[root@xb ~]# yum install redis

cat /etc/redis.conf | grep -v "^#" | grep -v "^$"

vi /etc/redis.conf

[root@xa ~]# service redis start

[root@xa ~]# netstat -anpt | grep 6379

[root@xa ~]# redis-cli -h 192.168.80.181 -p 6379

---------80.182 backup------------------------------

yum install -y epel-release

yum install redis -y

cat /etc/redis.conf | grep -v "^#" | grep -v "^$"

vi /etc/redis.conf

bind 0.0.0.0

service redis start

netstat -anpt | grep 6379

vi /etc/redis.conf

-------------配置商城项目中连接redis的参数---tomcat webe服务器

[root@xd WEB-INF]# vi /usr/local/tomcat8/webapps/SLSaleSystem/WEB-INF/classes/applicationContext-mybatis.xml

---------以下配置redis集群主从切换---只在主服务器是操作--------

redis-cli -h 192.168.80.181 info Replication //获取当前服务器的角色

vi /etc/redis-sentinel.conf

17 protected-mode no

69 sentinel monitor mymaster 192.168.80.181 6379 1 //1表示1台从 修改

98 sentinel down-after-milliseconds mymaster 3000 //故障切换时间单位是毫秒 不用改

service redis-sentinel start //启动集群

netstat -anpt | grep 26379

redis-cli -h 192.168.80.181 -p 26379 info Sentinel //查看集群信息

-----------验证主从切换----

在主上

service redis stop

--------mysql主服务器配置-------

vi /etc/my.cnf //[mysqld]下

----------mysql从服务器配置-------
