编译php后发生warning：configure:WARNING:unrecognizedoptions:--with-mysql 只是php7版本不支持mysql模块

./configure --help 查看configure的正确语法，重新编译php支持mysql，改用--with-pdo-mysql

php7版本正确的编译语句是：

         ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd-compression-support --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --with-mcrypt --with-libmbfl --enable-ftp --with-gd --enable-gd-jis-conv --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-pear --enable-maintainer-zts --with-ldap=shared --without-gdbm
