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 <link rel="stylesheet" href="http://cdn.example.com/style.css"> <script src="http://cdn.example.com/script.js"></script> 以上步骤可以帮助您在CentOS系统中优化域名解析,提高网站的访问速度和稳定性。
