1.安装依赖
yum -y install make gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip libcap lsof
安装epel-release源
yum install epel-release -y
安装 libiconv-1.14.tar.gz （这个还有个devl包）
wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
tar zavf libiconv-1.15.tar.gz
tar zxvf libiconv-1.15.tar.gz
cd libiconv-1.15
./configure
make
make instal
安装 libmcrypt-2.5.8.tar.gz
建议 yum install libmcrypt libmcrypt-de*
wget https://nchc.dl.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz
mhash-0.9.9.9.tar.bz2
yum install mhash -y
mcrypt-2.6.8.tar.gz
yum install mcrypt -y
通过yum 安装
wget http://mirrors.sohu.com/php/php-5.5.12.tar.gz
tar zxvf php-5.5.12.tar.gz
cd php-5.5.12

报这个错的原因是 --enable-fastcgi参数已经去除了，不再需要添加该参数，默认开启。下次安装删除此参数。

make && make install
修改fpm配置php-fpm.conf.default文件名称
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
复制php.ini配置文件
cp php.ini-production /usr/local/php/etc/php.ini
复制php-fpm启动脚本到init.d
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
赋予执行权限
chmod +x /etc/init.d/php-fpm
添加为启动项
chkconfig --add php-fpm
设置开机启动
chkconfig php-fpm on
按照标准，给php-fpm创建一个指定的用户和组
创建群组
groupadd www
创建一个用户，不允许登陆和不创主目录
useradd -s /sbin/nologin -g www -M www
立即启动php-fpm
service php-fpm start
#或者
/etc/init.d/php-fpm start

在安裝 PHP 到系统中时要是发生「undefined reference to libiconv_open'」之类的错误信息，那表示在「./configure 」沒抓好一些环境变数值。错误发生点在建立「-o sapi/cli/php」是出错，没給到要 link 的 iconv 函式库参数。 解决方法：编辑Makefile 大约77 行左右的地方: EXTRA_LIBS = ..... -lcrypt 在最后加上 -liconv，例如: EXTRA_LIBS = ..... -lcrypt -liconv 然后重新再次 make 即可。
或者用另一种办法
make ZEND_EXTRA_LIBS='-liconv'
ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/
