# tar -xvzf mod_evasive_1.10.1.tar.gz
# cd mod_evasive
# /usr/local/apache2/bin/apxs -c -i -a mod_evasive.c
奇怪，报错：
apxs:Error: Command failed with rc=65536
# yum install -y gcc gcc-c++ make autoconf libtool-ltdl-devel
# yum -y install binutils coreutils make dialog gcc gcc-*
# /usr/local/apache2/bin/apxs -c -i -a mod_evasive20.c
查看README文件，其中有解释：
Three different module sources have been provided:
Apache v1.3 API: mod_evasive.c
Apache v2.0 API: mod_evasive20.c
NSAPI (iPlanet): mod_evasiveNSAPI.c *
