CDN+集中存储环境搭建

一、cdn

部署环境：CentOS6

master：172.16.17.1

slave_telcom：172.16.17.2

slave_unicom：172.16.17.3

1.主服务器配置 172.16.17.1

修改主配置文件：

vi /etc/named.conf

options {
     directory "/var/named";
};

acl telcomip { 172.16.17.1;172.16.17.2; };
acl unicomip { 172.16.17.3; };

view telcom {
     match-clients { telcomip; };
     zone "ykyk.com" {
         type master;
         file "ykyk.com.telcom";
         notify yes;
         also-notify { 172.16.17.2; };
     };
};

view unicom {
     match-clients { unicomip; };
     zone "ykyk.com" {
         type master;
         file "ykyk.com.unicom";
         notify yes;
         also-notify { 172.16.17.3; };
     };
};

配置zone文件：

cd /var/named

[root@cdn_master named]# cp -p named.localhost ykyk.com.telcom
[root@cdn_master named]# cp -p named.localhost ykyk.com.unicom

[root@cdn_master named]# cat ykyk.com.telcom
$TTL 1D
@    IN SOA    @ rname.invalid. (
                     0    ; serial
                     1D    ; refresh
                     1H    ; retry
                     1W    ; expire
                     3H )    ; minimum
     NS    dns.ykyk.com.
dns    A    172.16.17.1
www    A    172.16.17.4

[root@cdn_master named]# cat ykyk.com.unicom
$TTL 1D
@    IN SOA    @ rname.invalid. (
                     0    ; serial
                     1D    ; refresh
                     1H    ; retry
                     1W    ; expire
                     3H )    ; minimum
     NS    dns.ykyk.com.
dns    A    172.16.17.1
www    A    172.16.17.5

2.从服务器配置---172.16.17.2

[root@cdn_slave_telcom slaves]# cat /etc/named.conf
options {
     directory "/var/named/slaves";
};

acl telcomip { 172.16.17.1;172.16.17.2; };
view telcom {
     match-clients { telcomip; };
     zone "ykyk.com" {
         type slave;
         file "ykyk.com.telcom";
         masters {172.16.17.1; };
     };
};

[root@cdn_slave_telcom slaves]# /etc/init.d/named restart

3.从服务器配置----172.16.17.3

[root@cdn_slave_unicom slaves]# cat /etc/named.conf
options {
     directory "/var/named/slaves";
};

acl unicomip { 172.16.17.3; };
view unicom {
     match-clients { unicomip; };
     zone "ykyk.com" {
         type slave;
         file "ykyk.com.unicom";
         masters { 172.16.17.1; };
     };
};

[root@cdn_slave_unicom slaves]# /etc/init.d/named start

至此cdn部署完成。

二、squid反向代理

环境搭建：

squid_telcom：172.16.17.4/192.168.7.10

squid_unicom：172.16.17.5/192.168.7.11

squid_telcom:

/etc/squid/squid.conf

squid_unicom:

至此，squid反向代理服务器部署完成。

内网nginx负载均衡客户端ip 192.168.7.1.

三、nignx负载均衡服务器配置

ip：采用双网卡配置 192.168.7.1/172.16.17.6

安装nginx

nignx版本1.13.8

[root@nignx nginx-1.13.8]# useradd –r –s /sbin/nologin nginx

[root@nignx nginx-1.13.8]# ./configure --user=nginx --group=nginx --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

make && make install

若：

ln -s /usr/local/lib/libpcre.so.1 /lib64

负载均衡

后端apache服务器ip为

apache_1:192.168.7.2.

apache_2:192.168.7.3

apache_3:192.168.7.4

启动nginx

[root@nignx conf]# /usr/local/webserver/nginx/sbin/nginx

至此，nginx配置完毕

四、apache服务器配置

192.168.7.2

192.168.7.3

192.168.7.4

安装软件

[root@apache_1 ~]# yum install httpd -y

[root@apache_2 ~]# yum install httpd -y

[root@apache_3 ~]# yum install httpd –y

配置集群环境

[root@apache_1 ~]# yum install cman rgmanager gfs2-utils lvm2-cluster iscsi-initiator-utils -y

[root@apache_2 ~]# yum install cman rgmanager gfs2-utils lvm2-cluster iscsi-initiator-utils -y

[root@apache_3 ~]# yum install cman rgmanager gfs2-utils lvm2-clust

er iscsi-initiator-utils -y

apache_1.ykyk.com:

[root@apache cluster]# ccs_tool create -2 clusterykyk
[root@apache cluster]# mv cluster.conf{,.bak}
[root@apache cluster]# ccs_tool create clusykyk
[root@apache cluster]# ccs_tool addfence zfence fence_manual
[root@apache cluster]# ccs_tool addnode -n 1 -f zfence apache1
[root@apache cluster]# ccs_tool addnode -n 2 -f zfence apache2

[root@apache cluster]# vi cluster.conf

[root@apache ~]# cd /etc/cluster/

[root@apache cluster]# ccs_tool create -2 clusterykyk

[root@apache cluster]# scp cluster.conf 192.168.7.3:/etc/cluster/

[root@apache cluster]# echo 123456 | passwd --stdin ricci

[root@apache cluster]# /etc/init.d/ricci start

apache_2.ykyk.com重复给密码和启动服务

在其他两台apache服务器上重复上述操作。

[root@apache_1 send_targets]# echo cluster >／var/www/html/index.html

curl 192.168.7.2

cluster 验证成功

至此，apache服务器配置完成

注意：存储端要先进行配置。

五、存储端
