make
make install
5、安装libpng
cd /usr/local/src
tar zxvf libpng-1.6.28.tar.gz
cd libpng-1.6.28
./configure --prefix=/usr/local/libpng --enable-shared
make
make install
6、安装freetype
cd /usr/local/src
tar zxvf freetype-2.7.1.tar.gz
cd freetype-2.7.1
./configure --prefix=/usr/local/freetype --enable-shared
make
make install
7、安装jpeg
cd /usr/local/src
tar zxvf jpegsrc.v9b.tar.gz
cd jpeg-9b
./configure --prefix=/usr/local/jpeg --enable-shared
make
make install
8、安装libgd
cd /usr/local/src
tar zxvf libgd-2.1.1.tar.gz
cd libgd-2.1.1
./configure --prefix=/usr/local/libgd --enable-shared --with-jpeg=/usr/local/jpeg --with-png=/usr/local/libpng --with-freetype=/usr/local/freetype --with-fontconfig=/usr/local/freetype --with-xpm=/usr/lib64 --with-tiff=/usr/local/tiff --with-vpx=/usr/local/libvpx
make
make install
说明：如果libgd编译失败，可以先跳过，直接使用系统默认的2.1.0版本，在编译php的时候把参数--with-gd=/usr/local/libgd修改为--with-gd即可。
9、安装t1lib
cd /usr/local/src
tar zxvf t1lib-5.1.2.tar.gz
cd t1lib-5.1.2
./configure --prefix=/usr/local/t1lib --enable-shared
make without_doc
make install
10、安装php
注意：如果系统是64位，请执行以下两条命令，否则安装php会出错。
cp -frp /usr/lib64/libltdl.so* /usr/lib/
cp -frp /usr/lib64/libXpm.so* /usr/lib/
10.1、安装php7.1.3
cd /usr/local/src
tar -zvxf php-7.1.3.tar.gz
cd php-7.1.3
export LD_LIBRARY_PATH=/usr/local/libgd/lib
./configure --prefix=/usr/local/php71 --with-config-file-path=/usr/local/php71/etc --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql-sock=/tmp/mysql.sock --with-pdo-mysql=/usr/local/mysql --with-gd=/usr/local/libgd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/lib64 --with-zlib-dir=/usr/local/zlib --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --enable-ctype --enable-mysqlnd
make #编译
make install #安装
说明：如果提示libgd版本错误，把php编译参数--with-gd=/usr/local/libgd修改为--with-gd即可。
cp php.ini-production /usr/local/php71/etc/php.ini #复制php配置文件到安装目录
rm -rf /etc/php.ini #删除系统自带配置文件
ln -s /usr/local/php71/etc/php.ini /etc/php.ini #添加软链接到 /etc目录
cp /usr/local/php71/etc/php-fpm.conf.default /usr/local/php71/etc/php-fpm.conf #拷贝模板文件为php-fpm配置文件
