I was able to log in this time. named is working properly. However, I do see that you have not increased the connections allowed to the server.
root@web [~]# sysctl -a | grep connt | egrep 'full|max' net.netfilter.nf_conntrack_tcp_timeout_max_retrans = 300 net.netfilter.nf_conntrack_tcp_max_retrans = 3 net.netfilter.nf_conntrack_max = 65536 net.netfilter.nf_conntrack_expect_max = 256 net.nf_conntrack_max = 65536 root@web [~]#
It appears that you changed the max connections for http, not the entire server

老外说了要让改运行进入网站的链接数 我改了apache 木有用 要改服务器的
把2个 65536 改成65536的2倍（整数倍） 13072 应该就可以了
改了之后用老外的root@web [~]# sysctl -a | grep connt | egrep 'full|max' 这个命令在查一下看看是不是改好了
