创建php用户
groupadd -r php && useradd -r -g php -s /bin/false -d /usr/local/php7 -M php #创建一个php用户， vi /etc/passwd 可以看到安装一些必要的编译依赖
yum -y install libxml2 libxml2-devel openssl openssl-devel curl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel安装libmcrypt-devel
yum后发现没有libmcrypt-devel这个包，编译又太麻烦，使用epel来安装
yum install epel-release
yum update
yum install libmcrypt libmcrypt-devel mcrypt mhash 最麻烦最重要的就是.configure
./buildconf --force #这个参数表示不检查编译环境是否完整，强行生成Makefile
./configure--prefix=/usr/local/php7 \
--exec-prefix=/usr/local/php7 \
--bindir=/usr/local/php7/bin \
--sbindir=/usr/local/php7/sbin \
--includedir=/usr/local/php7/include \
--libdir=/usr/local/php7/lib/php \
--mandir=/usr/local/php7/php/man \
--with-config-file-path=/usr/local/php7/etc \
--with-mysql-sock=/var/run/mysql/mysql.sock \
--with-mcrypt=/usr/include \
--with-mhash \
--with-openssl \
--with-mysqli=shared,mysqlnd \
--with-pdo-mysql=shared,mysqlnd \
--with-gd \
--with-iconv \
--with-zlib \
--enable-zip \
--enable-inline-optimization \
--disable-debug \
--disable-rpath \
--enable-shared \
--enable-xml \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-mbregex \
--enable-mbstring \
--enable-ftp \
--enable-gd-native-ttf \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-soap \
--without-pear \
--with-gettext \
--enable-session \
--with-curl \
--with-jpeg-dir \
--with-freetype-dir \
--enable-opcache \
--enable-fpm \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--without-gdbm \
--disable-fileinfo
下面两个参数不需要再加了
--enable-fastcgi 和with-mysql
会提示
configure: WARNING: unrecognized options: --enable-fastcgi

make & make install
make #倒上一杯咖啡慢慢的等吧，相对于mysql，php已经算是很快的了
make test #可选，如果测试的话又是好长好长时间
make install #最后一步

配置脚本文件
不然无法初始化php-fpm
cp php.ini-production /usr/local/php7/etc/php.ini #在源文件目录下
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm #在源文件目录下
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf添加系统变量
在任何目录下都可以执行php命令
echo -e '\nexport PATH=/usr/local/php7/bin:/usr/local/php7/sbin:$PATH\n' >> /etc/profile && source /etc/profile设置PHP日志目录和php-fpm进程文件（php-fpm.sock）目录
mkdir -p /var/log/php-fpm/ && mkdir -p /var/run/php-fpm && cd /var/run/ && chown -R nginx:nginx php-fpm
mkdir -p /var/lib/php/session
chown -R nginx:nginx /var/lib/php设置开机启动
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
启动服务
service php-fpm start 完毕！
