在 Apache 2.4 編譯 mod_evasive 時遇到以下錯誤：
mod_evasive20.c: In function ‘access_checker’:
mod_evasive20.c:142: error: ‘conn_rec’ has no member named ‘remote_ip’
mod_evasive20.c:146: error: ‘conn_rec’ has no member named ‘remote_ip’

apxs:Error: Command failed with rc=65536
在 Google 找了一下，原因出在 Apache 2.4 的 remote_ip 改名為 client_ip，要成功安裝，可以將 mod_evasive20.c 內的 remote_ip 字串改為 client_ip，方法如下：
cp mod_evasive20.c mod_evasive24.c
sed s/remote_ip/client_ip/g -i mod_evasive24.c
然後用 apxs 編譯新的 mod_evasive24.c：
apxs -i -a -c mod_evasive24.c
CentOS7下,Server version: Apache/2.4.6 (CentOS),安装 2.9.1.有如下错误:
In file included from modsecurity.h:49:0,
from apache2_config.c:17:

有什么建议吗?
