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
ip
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

[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
