# 前言 #

# 一：环境介绍 #

### 1.1：环境 ###

*  VMware软件
 *  一台centos7作为nginx代理服务器。IP地址：192.168.79.133
 *  一台centos7作为Tomcat1节点服务器。IP地址：192.168.79.134
 *  一台centos7作为Tomcat2节点服务器。IP地址：192.168.79.135

### 1.2：实验目的 ###

*  通过访问nginx代理服务器，自动访问到配置的集群节点服务器

# 二：Tomcat节点配置 #

### 2.1：两个节点服务器搭建Tomcat服务 ###

*  配置jdk环境
 *      [root@tomcat1 ~]# mount.cifs //192.168.23.1/ccc /mnt '//挂载宿主机目录' Password for root@//192.168.23.1/ccc: [root@tomcat1 ~]# cd /mnt/Tomcat/ [root@tomcat1 Tomcat]# tar zxvf jdk-8u91-linux-x64.tar.gz -C /usr/local '//解压环境保护' [root@tomcat1 Tomcat]# vim /etc/profile '//编辑环境' '//末尾添加以下环境' export JAVA_HOME=/usr/local/jdk1.8.0_91 export JRE_HOME=${ JAVA_HOME}/jre export CLASSPATH=.:${ JAVA_HOME}/lib:${ JRE_HOME}/lib export PATH=${ JAVA_HOME}/bin:$PATH
        [root@tomcat1 Tomcat]# source /etc/profile	'//引用环境'
 *  安装Tomcat
 *      [root@tomcat1 Tomcat]# tar zxvf apache-tomcat-8.5.16.tar.gz -C /usr/local	'//解压Tomcat软件包'
        [root@tomcat1 Tomcat]# cd /usr/local
        [root@tomcat1 local]# mv apache-tomcat-8.5.16/ tomcat	'//重命名Tomcat，方便管理'
        [root@tomcat1 local]# ln -s /usr/local/tomcat/bin/shutdown.sh /usr/local/bin	'//创建脚本软连接，方便使用'
        [root@tomcat1 local]# ln -s /usr/local/tomcat/bin/startup.sh /usr/local/bin		'//创建脚本软连接，方便使用'
        [root@tomcat1 local]# systemctl stop firewalld.service 	'//关闭防火墙'
        [root@tomcat1 local]# setenforce 0
 *  创建测试页面
 *      [root@tomcat1 local]# mkdir -pv /web/webapp1	'//创建站点目录'
        mkdir: 已创建目录 "/web"
        mkdir: 已创建目录 "/web/webapp1"
        [root@tomcat1 local]# cd /web/webapp1/
        [root@tomcat1 webapp1]# vim index.jsp	'//创建页面'
        <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>	'//设置支持中文字符集'
        <html>
         <head>
            <title>JSP test1 page</title>
         </head>
         <body>
            <% out.println("Welcome erbao Web");%>    '//输出的信息，Tomcat2节点内容设置为Welcome sambao Web'
         </body>
        </html>
 *  修改配置文件
 *      [root@tomcat1 webapp1]# vim /usr/local/tomcat/conf/server.xml 	'//修改配置文件中站点信息'
              <Host name="localhost"  appBase="webapps"
                    unpackWARs="true" autoDeploy="true">
                <Context docBase="/web/webapp1" path="" reloadable="false">    '//添加此段站点信息'  
                </Context>
        '//docBase：web应用的文档基准目录，reloadable：设置监视“类”是否变化，path：设置默认“类”'
 *  开启服务
 *      [root@tomcat1 webapp1]# startup.sh 	'//开启Tomcat服务'
        Using CATALINA_BASE:   /usr/local/tomcat
        Using CATALINA_HOME:   /usr/local/tomcat
        Using CATALINA_TMPDIR: /usr/local/tomcat/temp
        Using JRE_HOME:        /usr/local/jdk1.8.0_91/jre
        Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
        Tomcat started.
        [root@tomcat1 webapp1]# netstat -ntap |grep 8080	'//检查是否开启成功'
        tcp6       0      0 :::8080                 :::*                    LISTEN      31253/java
 *  网页测试

# 三：nginx服务器配置 #

### 3.1：搭建nginx服务 ###

*  安装环境
 *      [root@nginx ~]# yum install -y pcre-devel zlib-devel gcc gcc-c++ make	'//安装环境'
        [root@nginx ~]# useradd -M -s /sbin/nologin nginx	'//创建没有家目录，不允许登陆的nginx用户'
        [root@nginx ~]# mount.cifs //192.168.23.1/ccc /mnt
        Password for root@//192.168.23.1/ccc:  
        [root@nginx ~]# cd /mnt/LNMP-C7/
        [root@nginx LNMP-C7]# tar zxvf nginx-1.12.2.tar.gz -C /usr/local	'//解压nginx源码包'
 *  编译安装
 *      [root@nginx LNMP-C7]# cd /usr/local/nginx-1.12.2/
        [root@nginx nginx-1.12.2]# ./configure \	'//configure配置'
        > --prefix=/usr/local/nginx \
        > --user=nginx \
        > --group=nginx \
        > --with-http_stub_status_module \	'//状态统计模块'
        > --with-http_gzip_static_module \	'//压缩模块'
        > --with-http_flv_module	'//视频模块'
        [root@nginx nginx-1.12.2]# make && make install
 *  修改主配置文件
 *      [root@nginx nginx-1.12.2]# vim /usr/local/nginx/conf/nginx.conf
        ...省略内容
            #gzip  on; upstream tomcat-server { 	'//添加节点服务器地址'
                                server 192.168.79.134:8080 weight=1;
                                server 192.168.79.135:8080 weight=1;
                            }
            server { 
                listen       80;
                server_name  localhost;
        
                #charset koi8-r;
        
                #access_log  logs/host.access.log  main; location / { 
                    root   html;
                    index  index.html index.htm;
                    proxy_pass http://tomcat-server;	'//设置转发到节点服务器'
                }
        ...省略内容
 *  检查语法，关闭防火墙，开启服务
 *      [root@nginx nginx-1.12.2]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/	'//创建nginx软连接，方便管理'
        [root@nginx nginx-1.12.2]# nginx -t	'//检查语法'
        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@nginx nginx-1.12.2]# systemctl stop firewalld.service 	'//关闭防火墙'
        [root@nginx nginx-1.12.2]# setenforce 0
        [root@nginx nginx-1.12.2]# nginx	'//开启服务'
        [root@nginx nginx-1.12.2]# netstat -ntap |grep 80	'//检查开启是否成功'
        tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      96358/nginx: master
