nginx错误处理:ModSecurity PCRE do not match with compiled 的解决 

解决方法

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz

./configure --prefix=/usr/local/pcre-8.36 --libdir=/usr/local/lib/pcre --includedir=/usr/local/include/pcre
     configure有许多参数可配，具体参见./configure --help及手册
4、编译：
     make
5、安装：
     make install
6、检查：
     ls /usr/local 检查是否有pcre目录
     ls /usr/local/lib   检查是否有pcre目录
     ls /usr/local/include   检查是否有pcre目录
7、将库文件导入cache：
     方法1：在/etc/ld.so.conf中加入： ／usr/local/lib/pcre，然后运行ldconfig

参考

I believe it's more a bug than a feature.

Cpanel or EasyApache installs PCRE version 8.21 2011-12-12 int /opt/pcre/lib

But it does also install PCRE from YUM repository, which for Centos has Version 7.8 2008-09-05, which is too old.

I am not sure why EasyApache makes Apache and PHP (DSO, mod_ruid2) to use the system ones, even when it's compiled with /opt/pcre parameter.

Requesting PCRE version from command lines reports new version, but using phpinfo() reported old versions. Meaning apache , and PHP running as module uses system ones.

As i have little time nowadays, let's se if another users will encouter same problem, maybe they could provide more information.
