如果客户端是windows主机，则使用记事本程序打开C:\windows\System32\drivers\etc\hosts添加名称解析
当点击http://192.168.88.80页面中任意链接时，地址栏上的地址，都会变成192.168.88.7。通过以下方式修复它：
# 在nfs服务器上修改配置文件
[root@nfs01 ~]# vim /mnt/wordpress/wp-config.php 
# define('DB_NAME', 'wordpress')它的上方添加以下两行：
define('WP_SITEURL', 'http://192.168.88.80');
define('WP_HOME', 'http://192.168.88.80');

3.backup备份

服务端：backup

客户端：web01 web02 web03 

要求：

       每天晚上 00 点整在 Web 服务器上打包备份系统配置文件、网站程序目录及访问日志并通过 rsync 命令推送备份服务器 backup 上备份保留（备份思路可以是先在本地按日期打包，然后再推到备份服务器 backup 上） ，NFS 存储服务器同 Web 服务器，实际工作 中就是全部的服务器。

具体要求如下：
1)所有服务器的备份目录必须都为/backup。

2)要备份的系统配置文件包括但不限于：

a.定时任务服务的配置文件(/var/spool/cron/root)

b.开机自启动的配置文件(/etc/rc.local)

c.日常脚本的目录 (/server/scripts)。

d.防火墙 iptables 的配置文件(/etc/sysconfig/iptables)。

e.自己思考下还有什么需要备份呢？

3)Web 服务器站点目录(/var/html/www)。

4)Web 服务器 A 访问日志路径（/app/logs）

5)Web 服务器保留打包后的 7 天的备份数据即可(本地留存不能多于 7 天，因为太多硬盘会 满)

6)备份服务器上,保留每周一的所有数据副本，其它要保留 6 个月的数据副本。

7)备份服务器上要按照备份数据服务器的内网 IP 为目录保存备份，备份的文件按照时间名 字保存。

8）*需要确保备份的数据尽量完整正确，在备份服务器上对备份的数据进行检查，把备份的成功及失败结 果信息发给系统管理员邮箱中。
