要优化CentOS的DHCP性能,可以从以下几个方面入手:
max-lease-time 86400; # 默认租期 default-lease-time 86400; min-lease-time 3600; dynamic-bootp-lease-cutoff 0; dynamic-bootp-lease-length 86400; log-facility local7; echo "dhcpd hard nofile 65535" >> /etc/security/limits.conf sysctl -w net.ipv4.ip_local_port_range="1024 65535" sysctl -w net.core.somaxconn=1024 htop、iostat 等监控DHCP服务器的性能,及时发现和解决问题。ethtool 命令设置多队列:ethtool -L eth0 combined 8 通过以上优化措施,可以显著提升CentOS DHCP服务器的性能和效率。
