一、实验规划
1、模拟图：

2、IP规划：
    客户端IP：192.168.18.12
    转发器1：192.168.18.1
    转发器2：192.168.18.2
    apach+php1的IP :192.168.18.3
    apach+php2 的IP：192.168.18.9
    nginx+jsp1 的IP：192.168.18.4
    nginx+jsp2 的IP： 192.168.18.10
    转发器3的IP：192.168.18.5
    mysql+a 的IP： 192.168.18.6
    mysql+B1的IP： 192.168.18.7
    mysql+B2的IP：192.168.18.8

二、配置apach+php两个服务器
   1、配置好yum 环境
   2、yum install httpd php –y
   3、对于apach+ php1
        vim /var/www/html/index.php
            <? echo time() ?>
      对于apach+php2
        vim /var/www/html/index.php
            <? phpinfo() ?>
   4、启动服务
Service httpd start
三、配置nginx+tomact
   1、安装nginx
      rpm -ivh nginx-0.6.36-1.el5.i386.rpm
   2、安装Java环境
     chmod +x jdk-1_5_0-linux-i586-rpm.bin
     ./jdk-1_5_0-linux-i586-rpm.bin
     cp bash_profile /root/.bash_profile
     source /root/.bash_profile
3、测试安装是否成功
      java -version
      java version "1.5.0"

4、install tomcat
     tar fvxz apache-tomcat-6.0.20.tar.gz
     mv apache-tomcat-6.0.20 /usr/local/tomcat
测试启动和关闭
   [root@server1 tomcat]# /usr/local/tomcat/bin/startup.sh
   Using CaTaLIna_BaSE:   /usr/local/tomcat
   Using CaTaLIna_HOmE:   /usr/local/tomcat
   Using CaTaLIna_TmPDIR: /usr/local/tomcat/temp
   Using JRE_HOmE:       /usr/java/jdk1.5.0
   [root@server1 tomcat]# /usr/local/tomcat/bin/shutdown.sh
   Using CaTaLIna_BaSE:   /usr/local/tomcat
   Using CaTaLIna_HOmE:   /usr/local/tomcat
   Using CaTaLIna_TmPDIR: /usr/local/tomcat/temp
   Using JRE_HOmE:       /usr/java/jdk1.5.0
编写测试页面
   cd /usr/local/tomcat/webapps/ROOT/
对于nginx+jsp1
Vim test.jsp
    <%= new java.util.Date() %>
对于nginx+jsp2
Vim test.jsp
mv index.jsp   test.jsp
5、启动服务
   Service nginx start
   /usr/local/tomcat/bin/startup.sh
四、配置转发器1、2
1、安装nginx
    rpm -ivh nginx-0.6.36-1.el5.i386.rpm
2、安装keepalived install
ld1#tar fvxz keepalived-1.1.17.tar.gz
ld1#cd keepalived-1.1.17
ld1#./configure --prefix=/usr/local/keepalived
ld1#make
ld1#make install
安装后，把人家提供好的文件进行对应的复制！
ld1#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
ld1#cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
ld1#mkdir -pv /etc/keepalived
mkdir: 已创建目录 “/etc/keepalived”
#cp/root/keepalived.lay7.conf /usr/local/keepalived/etc/keepalived/keepalived.conf
#cp/root/keepalived.lay7.conf /etc/keepalived/keepalived.conf
ld1#ln -s /usr/local/keepalived/sbin/keepalived /sbin/
同样的安装步骤在ld2上执行一次！
几个特色地方按照老师要求整改
/etc/init.d/keepalived start
