在LNMP安装配置中，在进行php配置依赖包时遇到如何错误
wget http://cn2.php.net/distributions/php-5.4.37.tar.bz2
tar jxf php-5.4.37.tar.bz2
useradd -s /sbin/nologin php-fpm
cd php-5.4.37
useradd -s /sbin/nologin php-fpm
php依赖包参看lamp php安装
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --disable-ipv6 --with-curl
提示依赖包libmcrypt-devel错误，需要安装libmcrypt
因为centos6.x 默认的yum源没有libmcrypt-devel 这个包，只能借助第三方yum源
rpm -ivh "http://mirrors.ustc.edu.cn/epel/6Server/x86_64/epel-release-6-8.noarch.rpm" yum install -y libmcrypt-devel 可又提示epel-release已安装，还是不能yum libmcrypt-devel 现在只能进行编译安装libmcrypt 提供下载地址："http://ncu.dl.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz"
请注意2.5.6版本安装后php的./configure 还是会报错libmcrypt版本过低
"configure: error: libmcrypt version 2.5.6 or greater required"
