Linux环境下限制Apache2的连接数
在debian下安装：
#apt-get install libapache-mod-limitipconn
不知道安装到什么地方了
find / -name mod_limitipconn.so
/usr/lib/apache/1.3/mod_limitipconn.so
居然在1.3的目录下，复制到apache2的目录中
cp /usr/lib/apache/1.3/mod_limitipconn.so /usr/lib/apache2/modules/
修改apache2配置文件
nano /etc/apache2/httpd.conf
在最下面添加
ExtendedStatus On
LoadModule limitipconn_module modules/mod_limitipconn.so
重新启动/etc/init.d/apache2 restart
失败。
屏蔽LoadModule limitipconn_module modules/mod_limitipconn.so
正常
看来这个mod不直接支持apache2。
不过在官方的确写了安装方法，但是需要重新编译。
Installation
The instructions below are written for Apache 2.0.39 since that's what I had when I wrote the module, but they will also work with any later version of Apache 2.0.

cd httpd-2.0.39
./configure --with-module=aaa:../mod_limitipconn-0.22/mod_limitipconn.c
make
make install
Instructions for building as a Dynamic Shared Object (DSO):
