9.注意事项
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。
