官方网址: http://www.nowhere-land.org/programs/mod_vhost_limit/

安装:

apxs -c mod_vhost_limit.c -o /path/to/libexec/mod_vhost_limit.so

在 httpd.conf 加入:

LoadModule vhost_limit_module libexec/mod_vhost_limit.so
AddModule mod_vhost_limit.c

配置:

NameVirtualHost *


ServerName server1
DocumentRoot /some/where/1
MaxVhostClients 100



ServerName server2
DocumentRoot /some/where/2
MaxVhostClients 30



ServerName server3
DocumentRoot /some/where/3


其中: server1 被限制为 100 个并发线程数。 server2 被限制为 30 个并发线程数。 server3 没有被限制。

注:需 mod_status 的 ExtendedStatus On 支持!!

如超出限制的并发数在客户端就会出现503错误:

在 error_log 中将会有类似以下的错误提示:
