yum install -y epel-release

./configure --prefix=/home/work/app/php --with-fpm-user=work  --with-fpm-group=work  --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-curl --with-gd --with-iconv --with-freetype-dir --with-gettext --with-mcrypt --with-zlib-dir --with-libxml-dir
--with-zlib --with-bz2 --with-jpeg-dir  --with-pcre-dir --with-png-dir --with-openssl --with-xmlrpc --with-mhash --enable-fpm --enable-bcmath --enable-exif --enable-ftp --enable-zip --enable-mysqlnd --enable-sockets --enable-intl  --enable-ctype --enable-fileinfo
--enable-session --enable-mbstring --enable-sysvshm
