对一些大流量的web服务器来说，比较常见的问题就是time_wait会很多，起因大多都是apache里 keepalive 没开的原因，将这个开启，相对会少一些，但大流量时还是比较多，这里还有另外一个参数设置

net.ipv4.tcp_max_tw_buckets = 5000

如果不想time_wait不要太多，只要把这个值调低，就肯定不会超过了

但会出现一个新问题，就是在系统日志里，会很多类似这样的警告

Nov 27 15:50:01 localhost kernel: printk: 9498 messages suppressed.
Nov 27 15:50:01 localhost kernel: TCP: time wait bucket table overflow
Nov 27 15:50:06 localhost kernel: printk: 9562 messages suppressed.
Nov 27 15:50:06 localhost kernel: TCP: time wait bucket table overflow
Nov 27 15:50:11 localhost kernel: printk: 10120 messages suppressed.
Nov 27 15:50:11 localhost kernel: TCP: time wait bucket table overflow
Nov 27 15:50:16 localhost kernel: printk: 9182 messages suppressed.
Nov 27 15:50:16 localhost kernel: TCP: time wait bucket table overflow
Nov 27 15:50:21 localhost kernel: printk: 9626 messages suppressed.

这个警告其实不影响使用和性能，只是烦而已。我曾为避免这个提示，就将 net.ipv4.tcp_max_tw_buckets 调得很大，接着 time_wait 也就很大了。这也是上面这个问题，在网上搜索到的解决办法了。不想这个警告出现，重新编译内核，可以避免。

还有另一外问题，就是 fin_wait1 过多的问题，这个情况，一般的服务器上不会有。至少我的情况是这样

但在用了集群/负载均衡（LVS）中，下面的机器，就有这种情况，也曾为解决这个问题苦恼了挺久，经过今天的测试，也可以解决了。

只要在/etc/sysctl.conf 中加入

net.ipv4.tcp_keepalive_probes = 5
net.ipv4.tcp_keepalive_intvl = 15
net.ipv4.tcp_retries2 = 5
net.ipv4.tcp_orphan_retries = 3
net.ipv4.tcp_reordering = 5
net.ipv4.tcp_retrans_collapse = 0

就会减少很多了，关键的是 net.ipv4.tcp_orphan_retries 这个

在configure 加上 --without-zlib 可以编译通过

--with-libxml2-dir=/usr/local/libxml2

装好web环境,也总会用ab测试一下,可总记不住这结果,每过段时间就没印像了.所以,以后将在这贴上每次(或大部分)新配置机器的ab结果,并大概列一下,以便日后参考之用.

硬件,好像是HP的机器,具体是 Intel(R) Xeon(R) CPU           E5405  @ 2.00GHz,四核,2Gram,4个sas阵列(具体的方式不确定)

软件 redhat 5.3,简单配置,就apache+php+mysql,无GD等.
