haproxy+varnish实现discuz论坛的动静分离以及静态缓存

533442

一、目的：
        (1) 动静分离discuzx，静态资源通过NFS挂载至动态服务器中；
        (2) varnish缓存静态资源；

二、拓扑规划

三、步骤：
    1、先部署discuz的动静分离

        (1)在app动态服务器快速搭建LAMP环境：

1	yum install -y httpd mysql-server php php-mysql

        (2)创建discuz论坛的mysql用户：

1 2	MySQL [(none)]> GRANT ALL ON *.* TO 'nihao'@'localhost' IDENTIFIED BY '123456'; MySQL [(none)]> FLUSH PRIVILEGES;

        (3)部署discuz论坛程序：

1	[iyunv@localhost html]# unzip Discuz_X3.2_SC_UTF8.zip

        (4)要实现discuz的动静分离，首先要了解discuz的动静资源的存放目录位置，在discuz的根目录upload目录中，data和static存放的是静态资源：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

[iyunv@localhost upload]# tree -L 1 . ├── admin.php ├── api ├── api.php ├── archiver ├── config ├── connect.php ├── cp.php ├── crossdomain.xml ├── data  #静态资源 ├── favicon.ico ├── forum.php ├── group.php ├── home.php ├── index.php ├── install ├── member.php ├── misc.php ├── plugin.php ├── portal.php ├── robots.txt ├── search.php ├── source ├── static  #静态资源 ├── template ├── uc_client ├── uc_server └── userapp.php 10 directories, 17 files

        (5)知道了静态资源的位置，接下来就可以搭建static静态资源的静态服务器了，首先，快速搭建LAMP环境，这里就不演示了，搭建完成后启动NFS和配置NFS：

1 2 3 4 5 6 7 8 9 10 11 12

[iyunv@php ~]# yum install -y rpcbind nfs-utils [iyunv@php ~]# vim /etc/exports  #编辑NFS共享目录 [iyunv@php ~]# cat !$ cat /etc/exports /var/www/html/upload/data 10.1.0.0/16(rw) /var/www/html/upload/static 10.1.0.0/16(rw) [iyunv@php ~]# service rpcbind start [iyunv@php ~]# service ntf start [iyunv@php ~]# showmount -e 10.1.249.30 Export list for 10.1.249.30: /var/www/html/upload/static 10.1.0.0/16 /var/www/html/upload/data   10.1.0.0/16

        (6)回过头来，先把动态服务的初始化静态内容复制到静态服务器上，再动态服务器上将静态资源的两个目录挂上去：

1 2 3 4

[iyunv@localhost ~]# scp /var/www/html/upload/static/* 10.1.249.30:/var/www/html/upload/static/*  #拷贝文件时路径要一致 [iyunv@localhost ~]# scp /var/www/html/upload/data/* 10.1.249.30:/var/www/html/upload/data/* [iyunv@localhost ~]# mount.nfs 10.1.249.30:/var/www/html/upload/static/ /var/www/html/upload/static/ #挂载NFS [iyunv@localhost ~]# mount.nfs 10.1.249.30:/var/www/html/upload/data/ /var/www/html/upload/data/

        (7)OK,接下来可以安装haproxy来进行设置acl调度了：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88

[iyunv@localhost ~]# yum install -y haproxy [iyunv@localhost ~]# cat /etc/haproxy/haproxy.cfg #--------------------------------------------------------------------- # Example configuration for a possible web application.  See the # full configuration options online. # #   http://haproxy.1wt.eu/download/1.4/doc/configuration.txt # #--------------------------------------------------------------------- #--------------------------------------------------------------------- # Global settings #--------------------------------------------------------------------- global     # to have these messages end up in /var/log/haproxy.log you will     # need to:     #     # 1) configure syslog to accept network log events.  This is done     #    by adding the '-r' option to the SYSLOGD_OPTIONS in     #    /etc/sysconfig/syslog     #     # 2) configure local2 events to go to the /var/log/haproxy.log     #   file. A line like the following can be added to     #   /etc/sysconfig/syslog     #     #    local2.*                       /var/log/haproxy.log     #     log         127.0.0.1 local2     chroot      /var/lib/haproxy     pidfile     /var/run/haproxy.pid     maxconn     4000     user        haproxy     group       haproxy     daemon     # turn on stats unix socket     stats socket /var/lib/haproxy/stats #--------------------------------------------------------------------- # common defaults that all the 'listen' and 'backend' sections will # use if not designated in their block #--------------------------------------------------------------------- defaults     mode                    http     log                     global     option                  httplog     option                  dontlognull     option http-server-close     option forwardfor       except 127.0.0.0/8     option                  redispatch     retries                 3     timeout http-request    10s     timeout queue           1m     timeout connect         10s     timeout client          1m     timeout server          1m     timeout http-keep-alive 10s     timeout check           10s     maxconn                 3000 #--------------------------------------------------------------------- # main frontend which proxys to the backends #--------------------------------------------------------------------- listen stats     mode http     bind *:1080     stats enable     stats hide-version     stats uri     /admin     stats realm   Haproxy\ Statistics     stats auth    admin:admin     stats admin if TRUE frontend  main     bind *:80     acl url_static       path_beg       -i /static /images /javascript /stylesheets     acl url_static       path_end       -i .jpg .gif .png .css .js .html .ico     use_backend static          if url_static     default_backend             app #--------------------------------------------------------------------- # static backend for serving up images, stylesheets and such #--------------------------------------------------------------------- backend static     balance     roundrobin     server      static 10.1.249.30:80 check     rspadd X-Via:static #启用响应报文首部标志，以便观察是静态服务器反馈的 #--------------------------------------------------------------------- # round robin balancing between the various backends #--------------------------------------------------------------------- backend app     balance     roundrobin     server app 10.1.252.36:80 check     rspadd X-Via:app #启用响应报文首部标志，以便观察是动态服务器反馈的

        (8)OK,haproxy已经搭建完成，我们来测试一下：

静态服务器响应：


    2、动静分离已经实现，接下来在静态资源添加varnish来缓存静态资源：

        (9)安装配置varnish，由于前端haproxy已经进行了资源的分离，所以，varnish的配置基本用默认的配置就可以了

1 2 3 4 5 6

[iyunv@localhost ~]# yum install -y varnish-3.0.7-1.el7.centos.x86_64.rpm [iyunv@localhost ~]# vim /etc/varnish/default.vcl backend default {   .host = "10.1.249.30";   .port = "80"; }

        (10)修改HAproxy的配置文件，把静态资源的调度IP改为varnish：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87

[iyunv@localhost ~]# cat  /etc/haproxy/haproxy.cfg #--------------------------------------------------------------------- # Example configuration for a possible web application.  See the # full configuration options online. # #   http://haproxy.1wt.eu/download/1.4/doc/configuration.txt # #--------------------------------------------------------------------- #--------------------------------------------------------------------- # Global settings #--------------------------------------------------------------------- global     # to have these messages end up in /var/log/haproxy.log you will     # need to:     #     # 1) configure syslog to accept network log events.  This is done     #    by adding the '-r' option to the SYSLOGD_OPTIONS in     #    /etc/sysconfig/syslog     #     # 2) configure local2 events to go to the /var/log/haproxy.log     #   file.

OK,haproxy+varnish实现动静资源分离和静态资源的缓存到此暂告一段落
