记《网络应用服务实训》实践能力测试

测试说明：本测试重点考察linux环境下搭建高可用负载均衡网站平台的的能力。测试环境为win7系统安装vmware10，安装centos6.9虚拟机，所需软件包从互联网下载，测试时间为120分钟。

任务一、配置测试网络环境（20分）

  1. 按图示要求克隆虚拟机，设置网卡为NAT模式，配置网卡地址为静态地址，与虚拟机vmnet8在同一网段，按图示设置虚拟机hostname。
  2. 关闭防火墙（#services iptables stop），关闭SElinux（# setenforce 0），配置使用网络yum源。

检查点：nginx1虚拟机与主机能够ping通，虚拟机能够访问互联网（截图1）。
提示：编辑/etc/sysconfig/network-scripts/ifcfg-eth*文件，nginx1（截图2）。

任务二、在php1和php2上配置LAMP环境（20分）

  1. 使用yum方式安装httpd、php、php-mysqli等软件包，设置httpd的DocumentRoot 为/var/www，启动httpd服务；
  2. 在php1和php2的/var/www目录下编辑index.php文件。（截图3、截图4）

检查点：从主机浏览器访问“http://192.168.?.111”和“http://192.168.?.112”可以分别看到“php1@IP地址”和“php2@IP地址”。（截图5、截图6）。
提示：index.php文件中可以直接书写相应虚拟机IP地址，也可以使用php脚本获得服务器IP地址。

任务三、在nginx1和nginx2安装keepalived，配置高可用和负载均衡（20分）

  1. 安装epel yum源，使用yum方式安装nginx和keepalived；
  2. 在nginx1和nginx2配置一般轮询负载均衡，后端服务器为php1和php2，两台服务器配置文件（截图7、截图8）
  3. 编辑/etc/keepalived/keepalived.conf，使得nginx1成为master，nginx2作为backup，虚拟地址为“192.168.?.10”。编写应用nginx服务监控脚本。配置文件和脚本（截图9、截图10、截图11）

检查点1：在主机浏览器访问http://192.168.*.11时分别看到“php1@IP地址”和“php2@IP地址”。（截图12）
检查点2：nginx1停机或停止服务，访问http://192.168.*.10不间断。（截图13）

任务四、配置mysql主从复制和读写分离（15分）

  1. 使用yum方式在mysql-master和mysql-slave安装mysql-server，创建测试数据库、数据表并插入数据；在master上授权给复制用户（截图14）。
  2. 开启master的binlog日志，关闭slave的binlog日志，把master的测试数据库复制到slave。在slave上配置复制参数，开启复制，查看复制状态（截图15）。
  3. 在php1上安装mysql-proxy并配置读写分离，mysql-proxy.cnf配置文件（截图16）。

检查点1：在master上插入数据（截图17），slave上能够查询（截图18）。
检查点2：在php1上连接本机mysql-proxy，测试读写分离（截图19）。
提示1：master要启用binlog日志，要授权给复制用户，备份数据库时要锁表。在slave上CHANGE MASTER TO配置复制参数，start slave启用复制。
提示2：创建/etc/mysql-proxy.cnf配置文件，编辑rw-splitting.lua读写分离文件，启动mysql-proxy，在mysql-master和masql-slave上授权给mysql-proxy。

任务五、配置NFS支持nginx动静分离（15分）

  1. 在nfs上安装nfs-utils，配置共享目录，启动nfs服务。在php1上安装nfs-utils，查看nfs上的共享目录（截图14），并挂载到本地/var/www/share（截图15）。
  2. 在php1的web根目录编辑index.php脚本（截图16），并上传相关资源文件到nfs的共享目录。
  3. 在nginx1编辑/etc/nginx/conf.d/default.conf（截图17），支持动静分离。
    检查点1：在主机访问使用http://192.168.?.111/index.php（截图18）。
    检查点2：在主机访问使用http://192.168.?.11/index.php（截图19）。

任务六：安装zabbix，配置主机监控系统。（10分）

要求：在manager上安装zabbix server，搭建LAMP平台运行zabbix前端（截图20），在各台主机安装启用zabbix agent，在manager使用zabbix监控各台主机。

检查点：在manager使用ab软件对各台主机进行压力测试，使用zabbix能够监控到各台主机的cpu使用率、内存使用率。（截图21）
提示：#ab –c 并发数 –n 访问次数 http://192.168.*.10/test.php

自动部署脚本

#!/bin/bash

# version: 2.0

# 准备工作
# 1. 第一台虚拟机执行 # ./manager.sh clone_init
# 2. 先清理/etc/udev/rules.d/70-persistent-net.rules 再关机，再克隆虚拟机
# 3. 克隆后，修改各服务器网卡配置
# 4. 在manager上执行 ./manager.sh install
# 5. 等待安装
