实验拓扑图:

Tomcat WEB搭建+Nginx负载均衡动静分离+DNS解析的实验

实验环境:

在VMware workstation搭建虚拟环境,利用网络适配器的Nat和桥接模式模拟内网和外网环境。

实验过程中需要安装的工具包包括:vim unzip lrzsz lsof netstat bind gcc gcc-c++ pcre-devel openssl openssl-devel zlib-devel gd-devel

Tomcat WEB1:CentOS 7 192.168.81.51:8079

192.168.81.51:8080

Tomcat WEB2:CentOS 7 192.168.81.52:8079

192.168.81.52:8080

Nginx代理:CentOS 6.5      192.168.81.54

172.18.7.177

DNS服务器:CentOS 6.5      172.18.7.135

测试用客户机:    172.18.7.144

实验过程:

一、搭建Tomcat服务器

(提前下载apache-tomcat-7.0.47.tar.gz、jdk-8u20-linux-x64.rpm、Anynote_1.3.4.149.zip)

#systemctl stop firewalld   \\关闭服务器防火墙

#setenforce 0                        \\关闭selinux

#rpm -ivh jdk-8u20-linux-x64.rpm                      \\安装JAVA环境(这里选择1.8版本的JAVA)

#java –version

Tomcat WEB搭建+Nginx负载均衡动静分离+DNS解析的实验

#tar -zxvf apache-tomcat-7.0.47.tar.gz –C /mnt

#mv /mnt/ apache-tomcat-7.0.47.tar.gz /opt/tomcat

#chmod +x /opt/tomcat           \\设置目录可执行权限

#cp –ar /opt/tomcat /opt/tomcat2

#vim /opt/tomcat/conf/server.xml(修改三个端口号,在这里分别修改为8004,8008,8079)

shutdown 端口:8005  主要负责启动关闭.

ajp端口:8009 主要负责通过ajp均衡(常用于apache和tomcat整合)

http端口:8080 可以通过web页面直接访问(nginx+tomcata整合)

#/opt/ tomcat/bin/startup.sh

#/opt/ tomcat2/bin/startup.sh

#netstat –atnl(验证是否出现8008,8009,8079,8080,出现则为成功启动,这时可以通过在浏览器输入IP+端口访问Tomcat默认页面

#yum –y install mariadb mariadb-server

#systemctl start mariadb

#mysqladmin –uroot –p(输入密码)

#mysql –u root –p

#unzip Anynote_1.3.4.149.zip

#mv Anynote_1.3.4.149/Anynote.war /opt/tomcat/webapps/

#cp /opt/tomcat/webapps/Anynote.war /opt/tomcat2/webapps/

#cd ANynote_1.3.4.149 /Anynote/database

MariaDB [(none)]> create database Sqlite;

MariaDB [(none)]> \q

#mysql -uroot -p Sqlite < zeyu.sql

#vim /opt/tomcat/webapps/Anynote/WEB-INF/jdbc.properties

#vim /opt/tomcat2/webapps/Anynote/WEB-INF/jdbc.properties(修改部分如下)

重启tomcat1和tomcat2

# /opt/tomcat/bin/shutdown.sh

# /opt/tomcat/bin/startup.sh

# /opt/tomcat2/bin/shutdown.sh

# /opt/tomcat2/bin/startup.sh

登录tomcat查看Anynote是否搭建成功

二、搭建Nginx代理服务器(提前下载nginx-1.6.3.tar.gz、Anynote_1.3.4.149.zip)

# groupadd -g 108  -r nginx

# useradd -u 108 -r -g 108 nginx

# id nginx                    \\ uid=108(nginx) gid=108(nginx) 组=108(nginx)

# tar zxvf nginx-1.6.3.tar.gz

# cd nginx-1.6.3

#./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre --with-http_realip_module --with-http_image_filter_module --with-http_gzip_static_module

# make && make install

# /usr/local/nginx/sbin/nginx                     \\启动NGINX

# ps -ef |grep nginx

# vim /usr/local/nginx/conf/nginx.conf(修改配置文件实现负载均衡和动静分离)

upstream jsp_tomcat {

ip_hash;

server   192.168.81.51:8079 weight=1 max_fails=2 fail_timeout=30s;

server   192.168.81.52:8079 weight=1 max_fails=2 fail_timeout=30s;

}

upstream jpg_tomcat {

ip_hash;

server   192.168.81.52:8080 weight=1 max_fails=2 fail_timeout=30s;

server   192.168.81.51:8080 weight=1 max_fails=2 fail_timeout=30s;

}

}

# pkill nginx

# /usr/local/nginx/sbin/nginx                                                          \\重新启动nginx

# unzip Anynote_1.3.4.149.zip

# mv Anynote_1.3.4.149/Anynote/* /data/www/wugk/

访问代理IP测试(分别尝试访问了内网和外网的IP地址/Anynote/index.jsp)

四、配置两台Tomcat WEB的Mysql实现同步(双主复制)

修改两台服务器数据库的/etc/my.cnf文件

192.168.81.51:(server-id号不可以相同,replicate-do-db设置的是需要同步的数据库名称)

Tomcat WEB搭建+Nginx负载均衡动静分离+DNS解析的实验

192.168.81.52:

Tomcat WEB搭建+Nginx负载均衡动静分离+DNS解析的实验

# systemctl restart mariadb.service                           \\分别重新启动数据库

#mysql –uroot –p

192.168.81.51:

MariaDB [(none)]> grant replication slave on *.* to master@'192.168.81.52' identified by '123';

MariaDB [(none)]> flush privileges;

MariaDB [(none)]> show master status;(确认File和Position)

MariaDB [(none)]> stop slave;

Tomcat WEB搭建+Nginx负载均衡动静分离+DNS解析的实验

MariaDB [(none)]> change master to

master_host='192.168.81.52',

master_user='master',                                        \\用户的用户名

master_password='123',                                              \\用户的密码

master_log_file='mysql-bin.000001',               \\之前确认的File

master_log_pos=625;                                           \\之前确认的Posision

192.168.81.52:

MariaDB [(none)]> grant replication slave on *.* to master@'192.168.81.51' identified by '123';

MariaDB [(none)]> flush privileges;

MariaDB [(none)]> show master status;

MariaDB [(none)]> change master to

master_host='192.168.81.51',

master_user='master',

master_password='123',

master_log_file='mysql-bin.000001',

master_log_pos=625;

分别开启slave

MariaDB [(none)]> start slave;

查看slave状态:show slave status\G;(出现双YES为配置正确)

五、登录测试用客户机,设置DNS服务器为172.18.7.135

使用客户机访问www.e-qianxi.com并添加任务

使用真机分别访问Tomcat的IP地址端口检测是否数据同步。

(在双主复制搭建之前添加的任务不会同步,在双主复制搭建之后添加的任务所有Tomcat都会有)

(在同一个tomcat服务器上的虽然端口8079的和8080不同,但是调用的是同一个数据库)
