1、安装
2、重新启动一下keepalived查看IP
六、验证双机热备
1、查看调度器备的IPip漂移说明keepalived生效 2、访问静态页面
3、 访问动态页面 一、环境
三台主机分别为
192.168.28.3 tomcat
192.168.28.4 nfs
192.168.28.5 tomcat
192.168.28.6 nginxkeepalived
192.168.28.7 nginxkeepalived
二、配置tomcat
两台tomcat配置把解压包拖进主机解压移动
tar xf apache-tomcat-8.5.16.tar.gz tar xf apache-tomcat-8.5.16.tar.gz mv apache-tomcat-8.5.16 /usr/local/tomcatmv apache-tomcat-8.5.16 /usr/local/tomcatln -s /usr/local/tomcat/bin/startup.sh /usr/bin/qd1ln -s /usr/local/tomcat/bin/shutdown.sh /usr/bin/tz1###创建挂载目录 /usr/local/tomcat mkdir webapps1 ###修改tomcat的访问目录 vim /usr/local/tomcat/conf/server.xml ###修改host字段插入 Context path docBase/usr/local/tomcat/webapps1 / 三、配置nfs共享
mkdir /opt/web1mkdir /opt/web2vim /etc/exportssystemctl restart nfsexportfs##安装nfs服务
yum -y install nfs
##创建共享目录
mkdir /opt/web1
mkdir /opt/web2
##配置nfs的配置文件vim /etc/exports systemctl restart nfs 回到两台Tomcat的上查看共享目录
[rootlocalhost tomcat]# mkdir webapps1showmount -e 192.168.28.4mount 192.168.28.4:opt/web2 /usr/local/tomcat/webapps1echo tomcat2 webapps1/index.jspqd1##查看挂载情况 df ###分别书写测试页面 echo tomcat1 webapps1/index.jsp echo tomcat2 webapps1/index.jsp ##启动Tomcat qd1 qd0 ##查看端口 netstat -anptu |grep java 测试页面 四、配置nginx
1、两台都需要折磨配置
192.168.28.6
192.168.28.7
#安装
yum -y install epel-release.noarch yum -y install nginxvim /etc/nginx/nginx.conf2、在http下面插入这两条信息 在server字段插入下方这句话 启动nginx 访问一下测试页面 查看调度器 五、配置keepalived
1、安装
192.168.28.6
192.168.28.7 yum -y install keepalivedvim /etc/keepalived/keepalived.conf systemctl restart keepalived.service scp /etc/keepalived/keepalived.conf 192.168.28.7:/etc/keepalived/keepalived.conf !

}2、重新启动一下keepalived查看IP
systemctl restart keepalived.service ip a VIP页面访问测试
静态页面 动态页面 六、验证双机热备
模拟调度器主宕机systemctl stop keepalived使用调度器备访问
1、查看调度器备的IPip漂移说明keepalived生效 2、访问静态页面 3、 访问动态页面
