在CentOS系统中,优化域名解析可以通过以下几个步骤来实现:
sudo yum install bind-chroot -y
systemctl stop firewalld
setenforce 0
vi /etc/named.conf
# 修改内容
listen-on port 53 { any; };
allow-query { any; };
vi /etc/named.rfc1912.zones
# 添加新的DNS区域
zone "example.com" IN {
type master;
file "example.com.zone";
};
systemctl restart named
vi /etc/resolv.conf
# 添加多个DNS服务器
nameserver 8.8.8.8
nameserver 8.8.4.4
sudo yum install nscd
vi /etc/nscd.conf
# 启用缓存
enable-cache hosts yes
positive-time-to-live hosts 5
service nscd start
chkconfig nscd on
vi /etc/httpd/conf/httpd.conf
# 启用Gzip压缩
LoadModule deflate_module modules/mod_deflate.so
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript application/json application/x-javascript
