1、https://github.com/xdebug/xdebug 根据步骤顺序执行
     a) 错误一
     遇到错误 ./rebuild.sh: 3: ./rebuild.sh: phpize: not found
         vim ./rebuild.sh
         将 phpize 替换为全路径 /usr/local/php/v7.1.9/bin/phpize
         /usr/local/php/v7.1.9/bin/phpize && ./configure --enable-xdebug-dev && make clean && make -j 5 all && make install
     b) 错误二
         configure: error: Cannot find php-config. Please use --with-php-config=PATH
         添加 --with-php-config=/usr/local/php/v7.1.9/bin/php-config
         /usr/local/php/v7.1.9/bin/phpize && ./configure --enable-xdebug-dev --with-php-config=/usr/local/php/v7.1.9/bin/php-config && make clean && make -j 5 all && make install

      解决完错误重新执行 sudo ./rebuild.sh
      安装完成

2、修改php.ini
     [XDebug]
        xdebug.profiler_append = 0
        xdebug.profiler_enable = 1
        xdebug.profiler_enable_trigger = 0
        xdebug.remote_enable = 1
        xdebug.remote_mode = "req"
        xdebug.remote_handler = "dbgp"
        xdebug.remote_host = "127.0.0.1"
        xdebug.remote_port = 9001
        xdebug.idekey="php"
        xdebug.remote_autostart = no

     zend_extension = /usr/local/php/v7.1.9/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so
