之前写过给Directadmin上Varnish前端，现在折腾下nginX前端- - 本方法只适用与单ip，全部请求转发到apache。
2013-4-20 Debian亲测可用。
1.安装nginx
CentOS:
vi /etc/yum.repos.d/nginx.repo #####添加以下 [nginx] name=nginx repo baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/ gpgcheck=0 enabled=1 ##### yum install nginx
Debian:
echo "deb http://packages.dotdeb.org squeeze all" >>/etc/apt/sources.list echo "deb-src http://packages.dotdeb.org squeeze all">/etc/apt/sources.list wget http://www.dotdeb.org/dotdeb.gpg cat dotdeb.gpg | apt-key add - apt-get install nginx-full -y
2. 修改/etc/nginx/nginx.conf

# multi_accept on;
}

set $no_cache 1;
}
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in|uin") {
set $no_cache 1;
}
location /

}
}
3. 修改apache端口
sed -i "s#ips.conf#ips_hack.conf#g" /etc/httpd/conf/extra/httpd-vhosts.conf cp /etc/httpd/conf/ips.conf /etc/httpd/conf/ips_hack.conf sed -i "s#:80#:800#g" /etc/httpd/conf/ips_hack.conf sed -i "s#:80#:800#g" /etc/httpd/conf/extra/httpd-vhosts.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/ips_virtual_host.conf sed -i "s#:|PORT_80|#:800#g" /usr/local/directadmin/data/templates/virtual_host2_sub.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/virtual_host2_sub.conf sed -i "s# |MULTI_IP|##g" /usr/local/directadmin/data/templates/virtual_host2_sub.conf sed -i "s/CustomLog/#CustomLog/g" /usr/local/directadmin/data/templates/virtual_host2_sub.conf sed -i "s#:|PORT_80|#:800#g" /usr/local/directadmin/data/templates/virtual_host.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/virtual_host.conf sed -i "s# |MULTI_IP|##g" /usr/local/directadmin/data/templates/virtual_host.conf sed -i "s/CustomLog/#CustomLog/g" /usr/local/directadmin/data/templates/virtual_host.conf sed -i "s#:|PORT_80|#:800#g" /usr/local/directadmin/data/templates/virtual_host_sub.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/virtual_host_sub.conf sed -i "s# |MULTI_IP|##g" /usr/local/directadmin/data/templates/virtual_host_sub.conf sed -i "s/CustomLog/#CustomLog/g" /usr/local/directadmin/data/templates/virtual_host_sub.conf sed -i "s#:|PORT_80|#:800#g" /usr/local/directadmin/data/templates/redirect_virtual_host.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/redirect_virtual_host.conf sed -i "s# |MULTI_IP|##g" /usr/local/directadmin/data/templates/redirect_virtual_host.conf sed -i "s#:|PORT_80|#:800#g" /usr/local/directadmin/data/templates/virtual_host2.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/templates/virtual_host2.conf sed -i "s# |MULTI_IP|##g" /usr/local/directadmin/data/templates/virtual_host2.conf sed -i "s/CustomLog/#CustomLog/g" /usr/local/directadmin/data/templates/virtual_host2.conf sed -i "s#Port 80#Port 800#g" /usr/local/directadmin/data/templates/httpd.conf sed -i "s#Listen 80#Listen 800#g" /usr/local/directadmin/data/templates/httpd.conf sed -i "s#Listen 80#Listen 800#g" /etc/httpd/conf/httpd.conf sed -i "s#:80#:800#g" /usr/local/directadmin/data/users/*/httpd.conf
4. 禁止外网ip访问
iptables -I INPUT -p TCP --dport 800 -j DROP iptables -I INPUT -s 1.2.3.4 -p TCP --dport 800 -j ACCEPT #1.2.3.4改为外网ip
5. 重启
service apache restart /etc/init.d/nginx start
如无特殊情况，此时应该是成功了。。。
很好
这样应该能节约内存吧
