PHP编译安装报错： mcrypt.h not found. Please reinstall libmcrypt.

解决方法：
1.为系统安装perl-Geo-IP，默认yum源中没有这个包，特意安装epel第三方yum源[[email protected] ~] rpm -Uvh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm

这里我们又遇到一个错误，解决方法：
解决办法是编辑/etc/yum.repos.d/epel.repo，把基础的恢复，镜像的地址注释掉
#baseur
lmirrorlist
改成
baseurl
#mirrorlist
步骤如下：（蓝色为需修改的地方）
? [[email protected] ~]# vi /etc/yum.repos.d/epel.repo
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1
?[epel-source]
name=Extra Packages for Enterprise Linux 6 - $basearch - Source
baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1
修改完之后保存退出。?
上面下划线部分错误，是原博主遇到的错误及解决办法。 而我遇到的则是这个错误
Error：Cannot retrieve repository metadata (repomd.xml) for repository: rpmforge. Please verify its path and try again
解决办法是
yum Error: Cannot retrieve repository metadata (repomd.xml) for repository:xxxxxx.
这个错误其实很简单，错误信息已经提示你，就是xxxxxx.repo这个文件有问题。
（1）打开/etc/yum.repos.d/xxxxxx.repo文件
（2）enabled=1(可能有多个，具体改几个，有待测试。 我当时遇到的是第一个需要改。 改了就成功了。)改成enabled=0
3.再次运行?yum install -y libmcrypt-devel
Installed:libmcrypt-devel.i686 0:2.5.8-9.el6 #安装完成
4.?[[email protected] src]# cd php-5.3.27
[[email protected] php-5.3.27]# ./configure \ --prefix=/usr/local/php \ --with-apxs2=/usr/sbin/apxs \ --with-config-file-path=/usr/local/php/etc \ --with-mysql=/usr/local/mysql \ --with-libxml-dir \ --with-gd \ --with-jpeg-dir \ --with-png-dir \ --with-freetype-dir \ --with-iconv-dir \ --with-zlib-dir \ --with-bz2 \ --with-openssl \ --with-mcrypt \ --enable-soap \ --enable-gd-native-ttf \ --enable-mbstring \ --enable-sockets \ --enable-exif \ --disable-ipv6
??Thank you for using PHP.
[[email protected] php-5.3.27]# echo $?
