1 实验拓扑

2 需求

  • RS-01和RS-02对外提供WEB服务。
  • RS-01搭建LAMP,PHP通过http模块方式提供。
  • RS-02搭建LAMP,PHP通过fpm方式提供。
  • RS-01和RS-02之间的关系。
    • RS-01对外提供NFS服务,作为两个LAMP环境的共享存储,负责存储用户上传的资源,例如:图片、文档等。
    • RS-02对外提供Mariadb服务,作为两台LAMP环境的共享数据库,负责存储用户的帖子、文字等。
  • 对外提供的域名为www.example.com

    建议现将下面的文章全部浏览完成,再做实验。

3 软件版本

本次使用root用户进行安装,软件全部在每台设备的/root/目录下
apr-1.6.3.tar.bz2
apr-util-1.6.1.tar.bz2
Discuz_X3.1_SC_UTF8.zip
httpd-2.4.6.tar.bz2
mariadb-5.5.46-linux-x86_64.tar.gz
phpMyAdmin-4.0.10.20-all-languages.zip
wordpress-4.7.4-zh_CN.tar.gz
php-5.3.27.tar.gz

4 VS配置

一共部署了3个软件,wordpress、discuz、phpMyAdmin;

wordpress和discuz工作在rr模式下也可以正常的访问网页不会出现session超时的现象,可以访问速度非常慢;如果将模式改为sh或者删除一个rs主机,速度就快起来了;

phpMyAdmin工作在rr模式下会提示session超时;

sysctl -w net.ipv4.ip_forward=1
yum -y install ipvsadm
ipvsadm -A -t 10.207.51.113:80 -s rr
ipvsadm -a -t 10.207.51.113:80 -r 10.0.0.101:80 -m
ipvsadm -a -t 10.207.51.113:80 -r 10.0.0.102:80 -m

5 RS_01部署NFS

因为NFS是共享存储,RS-01和RS-02都需要使用,所以提前部署。

yum install -y rpcbind nfs-utils &&\
echo '/nfsdata/wordpress 10.0.0.0/24(rw,sync,root_squash,all_squash,anonuid=48,anongid=48)' >/etc/exports &&\
echo '/nfsdata/discuz 10.0.0.0/24(rw,sync,root_squash,all_squash,anonuid=48,anongid=48)' >>/etc/exports &&\
mkdir -p /nfsdata/wordpress &&\
mkdir -p /nfsdata/discuz &&\
systemctl start rpcbind &&\
systemctl start nfs &&\
systemctl enable rpcbind &&\
systemctl enable nfs [root@rs_01 ~]# showmount -e
Export list for rs_01:
/nfsdata/discuz 10.0.0.0/24
/nfsdata/wordpress 10.0.0.0/24

注意:要确保RS-01和RS-02上的apache用户的UID和GID都是48

6 RS_02部署Mariadb

因为Mariadb是共享数据库,RS-01和RS-02都需要使用,所以提前部署。

http://10.0.0.101/wordpress/wp-admin/setup-config.php

在本次环境中,使用上面这个链接安装是不对的,要使用最后绑定给VIP的域名(www.example.com)来安装wordpress,不要直接使用RS-01的IP来安装,具体原因见下文,此处假定使用了上面的安装方式;

正确安装方式:将www.example.com临时解析为10.0.0.101;然后执行安装http://www.example.com/wordpress/wp-admin/setup-config.php

8.3 Wordpress

其实将RS-01的wordpress目录复制过来就行,然后为/data/wordpress/wp-content并挂在共享存储,最后更改一下属主属组为apache,

如果挂在不上需要查看网络原因,可以先安装nfs-utils,然后使用showmount -e 10.0.0.101命令查看可挂载的目录

yum install -y rpcbind &&\
systemctl start rpcbind &&\
systemctl enable rpcbind &&\
mkdir -p /data/www/ &&\
tar -xf wordpress-4.7.4-zh_CN.tar.gz -C /data/www/ &&\
mv /data/www/wordpress/wp-content /data/www/wordpress/wp-content.bak &&\
mkdir /data/www/wordpress/wp-content &&\
chown -R apache: /data/www/wordpress/ &&\
mount -t nfs -o bg,timeo=300,soft,retrans=50,rsize=180000,wsize=180000,rw,noexec,sync 10.0.0.101:/nfsdata/wordpress /data/www/wordpress/wp-content/ &&\
cd /data/www/ &&\
cp wordpress/wp-config-sample.php wordpress/wp-config.php &&\
sed -i 's#database_name_here#wordpress#g' wordpress/wp-config.php &&\
sed -i 's#username_here#wordpress#g' wordpress/wp-config.php &&\
sed -i 's#password_here#123123#g' wordpress/wp-config.php &&\
sed -i 's#localhost#10.0.0.102#g' wordpress/wp-config.php &&\
chown -R apache:apache /data/www/wordpress/

9 故障解决

部署完RS-01的LAMP环境之后,挂载了共享存储作为wordpress的用户上传文件的目录,并且安装了wordpress,然后测试登录,发布文章,发现没问题。
部署完RS-02的LAMP环境之后,挂载了共享存储作为wordpress的用户上传文件的目录,并且安装了wordpress(和RS-01使用的是一个mariadb,RS-02不用再次创建表,支持读取RS-01创建的表),测试登录,发现总是直接跳转到RS-01上(在浏览器里输入10.0.0.102,只要一点击登录或者浏览文章,URL就跳转到了10.0.0.101),而且通过抓包发现了下面这种情况,而且通过查看数据库,发现wordpress数据库中很多表的字段里面都写了RS-01的地址。所以无法实现最初的需求;

下面是解决问题过程中,测试先安装RS-02,然后安装RS-01时抓的报文,这里作为示例


最后解决的方法

上一次部署的时候,我是输入http://10.0.0.101/wordpress/wp-admin/setup-config.php进行安装的。

这回我是输入http://www.example.com/wordpress/wp-admin/setup-config.php进行安装的。
此时www.example.com 对应RS-01的地址10.0.0.101。
部署完成后,发布文档,上传文件。没有问题 将www.example.com对应RS-02的地址10.0.0.102。
查看之前发布的文章,查看之前上传的文件。发布新的文章,都没有问题。 最后配置LVS-NAT。将www.example.com对应LVS的VIP地址,10.207.51.113,调度方式选择成RR(没有选择SH)。
访问www.example.com登录wordpress。发布文章,查看之前的文章,上传的文件。没有问题。
并且session没有问题(这个不清楚为什么,选择的是RR,竟然没有出问题,但是访问速度非常的慢;一旦将模式改为SH或者删除一台主机就访问速度就快了;)

此时收的到的报文


通过查看wordpress创建的表,发现在很多表的字段中,wordpress程序会绑定安装的时候使用的URL,之前绑定了成了http://10.0.0.101/wordpress所以会出现跳转的情况


10 phpMyAdmin

配置比较简单,参考我之前的文章即可;

之后又部署了phpMyAdmin之后,使用LVS-NAT模式,调度方式使用RR,发现每点击几次个页面,或者刷新几次,就会出现出现session过期的情况,更换调度方式为SH后解决问题;

因为Connection: Keep-Alive的原因,所以不是刷新一次就切换一台服务器,如果Connection: closed,就会变成刷新一次换一个服务器了;

11 Discuz

配置比较简单,此处略

最后安装了Discuz,这个软件就不存在wordpres绑定URL的情况;而且这个软件也是在调度模式为RR的时候没有问题,担仍然是很慢,换成SH模式就快了;
