Apache安装cloudflare和bw模块

1. 安装httpd-devel
2. 下载并安装mod_cloudflare

   wget https://www.cloudflare.com/static/misc/mod_cloudflare/mod_cloudflare.c
   apxs -a -i -c mod_cloudflare.c
   

3. 下载并安装mod_bandwidth

   wget http://bwmod.sourceforge.net/files/mod_bw-0.7.tgz
   tar -zxvf mod_bw-0.7.tgz
   cd mod_bw
   apxs -i -a -c mod_bw.c
   

4. 如果重启apache时出现错误：Cannot load /usr/lib64/httpd/modules/mod_bw.so into server: /usr/lib64/httpd/modules/mod_bw.so: undefined symbol: apr_atomic_cas

   先编辑mod_bw.c

   #ifdef APR_MAJOR_VERSION  //添加这行
   #if (APR_MAJOR_VERSION < 1)
     #define apr_atomic_inc32 apr_atomic_inc
     #define apr_atomic_dec32 apr_atomic_dec
     #define apr_atomic_add32 apr_atomic_add
     #define apr_atomic_cas32 apr_atomic_cas
     #define apr_atomic_set32 apr_atomic_set
   #endif
   #endif //添加这行
   

   然后重新编译该模块
