make
make install

出现 configure: error: mcrypt.h not found. Please reinstall libmcrypt时

cd /usr/local/src
wget http://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gz
tar -zxvf libmcrypt-2.5..tar.gz
cd /usr/local/src/libmcrypt-2.5.
./configure --prefix=/usr/local
make
make install

出现 Don't know how to define struct flock on this system, set --enable-opcache=no

[root@localhost php-7.1.]# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
# 添加这行
/usr/local/lib
~
#保存后使之生效
ldconfig -v 

安装完之后, 可以直接运行PHP内建的web server,

# 使用/var/www/html/ 作为root目录, 使用php.ini作为环境配置
php -S 0.0.0.0: -t /var/www/html -c php.ini
# 后台运行, 且不保留任何输出
nohup php -S 0.0.0.0: -t /var/www/html >/dev/null >& &
# 后台运行, 将日志输出到当前路径下的phpd.log
nohup php -S 0.0.0.0: -t /var/www/html >phpd.log >& &
# 后台运行, 将日志输出到当前路径下的phpd.log, 使用bar.php作为路由脚本
nohup php -S 0.0.0.0: -t /var/www/html bar.php >phpd.log >& &

路由脚本: 每次请求都会先执行这个脚本。如果这个脚本返回 FALSE ，那么直接返回请求的文件（例如请求静态文件不作任何处理）。否则会把输出返回到浏览器

配置php和php-fpm

# 将默认的产品配置文件复制到配置目录
cp /usr/src/php-7.1./php.ini-production /usr/local/php/etc/php.ini
# 复制默认的php-fpm配置文件
cd /usr/local/php/etc/
mv php-fpm.conf.default php-fpm.conf
mv php-fpm.d/www.conf.default php-fpm.d/www.conf
# 将php-fpm添加到服务
cd /usr/src/php-7.1./sapi/fpm/
cp init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
systemctl start php-fpm
# 检查是否正常运行
ps aux|grep php-fpm

修改nginx配置文件支持PHP

vi /opt/nginx/conf/nginx.conf

# 把前面的#注释符号去掉，把script改为$document_root最终如下：
location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /$document_root$fastcgi_script_name;
    include        fastcgi_params;
}

然后重新载入nginx配置, 安装就完成了
