问： /etc/sysctl.conf CentOS5.5中可以将所有内容清空直接替换为如下内容:
net.ipv4.ip_forward = 0net.ipv4.conf.default.rp_filter = 1net.ipv4.conf.default.accept_source_route = 0kernel.sysrq = 0kernel.core_uses_pid = 1net.ipv4.tcp_syncookies = 1kernel.msgmnb = 65536kernel.msgmax = 65536kernel.shmmax = kernel.shmall = net.ipv4.tcp_max_tw_buckets = 6000net.ipv4.tcp_sack = 1net.ipv4.tcp_window_scaling = 1net.ipv4.tcp_rmem = 4096 87380 net.ipv4.tcp_wmem = 4096 16384 net.core.wmem_default = net.core.rmem_default = net.core.rmem_max = net.core.wmem_max = net.core.netdev_max_backlog = 262144net.core.somaxconn = 262144net.ipv4.tcp_max_orphans = net.ipv4.tcp_max_syn_backlog = 262144net.ipv4.tcp_timestamps = 0net.ipv4.tcp_synack_retries = 1net.ipv4.tcp_syn_retries = 1net.ipv4.tcp_tw_recycle = 1net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_mem = net.ipv4.tcp_fin_timeout = 1net.ipv4.tcp_keepalive_time = 30net.ipv4.ip_local_port_range = 1024 65000
,centos 6.9 配置文件这样改 有问题么 处理高并发
问：
答：您好，高并发除了内核外，还需要对web服务进行优化，如nginx等，关于您的问题，您可参考：http://blog.sina.com.cn/s/blog_54e03a740102vfu6.html 进一步了解 ,非常感谢您长期对我司的支持.由此给您带来的不便之处,敬请原谅!谢谢!
