2.mod_limitipconn
wget http://dominia.org/djao/limit/mod_limitipconn-0.24.tar.bz2
tar xf mod_limitipconn-0.24.tar.bz2
cd mod_limitipconn-0.24
apxs -c -i -a mod_limitipconn.c
ps:该步会自动将mod_limitipconn.so模块编译到apache对应的modules中，还会在http.conf文件中自动添加loadmodules语句
2.1 确保加载了mod_status模块
2.2 确保ExtendedStatus On
2.3 配置
#mod_limitipconn
LoadModule limitipconn_module /usr/lib64/httpd/modules/mod_limitipconn.so
<IfModule mod_limitipconn.c>
MaxConnPerIP 15
NoIPLimit image/*
NoIPLimit text/css
NoIPLimit application/x-javascript
<LocationMatch "/test/test\.php">
