CentOS7下升级PHP ： Requires: libgmp.so.3()(64bit)

rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

yum list "php*"

yum install php71w

CentOS7下升级PHP碰到的问题：

Resolving Dependencies

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

这个问题百度里找不到解决办法，源码编译 gmp-4.3.1-12.el6.i686.rpm 生成了 libgmp.so.3 库也不行。

最后翻墙上了google，一下就找到解决办法了。

下载安装 compat-libgmp-4.3.1-1.sl7.x86_64.rpm

继续安装又碰到问题：

解决方案清理 yum clean all

以为下来就可以愉快的玩耍了，然而 php 的 mysql_connect 竟然用不成，google了一下，是PHP的MySQL扩展被从php中移除了。

解决办法有两个，一个是从源码编译安装PHP，这个太费事了，要编译半天。

另外就是单独安装php扩展。

git clone https://github.com/php/pecl-database-mysql.git

或者下面地址下载：

http://git.php.net/?p=pecl/database/mysql.git;a=summary

yum install php70w-devel

找到phpize的路径： /usr/bin/phpize 执行如下命令

cd ./pecl-database-mysql

/usr/bin/phpize

./configure --with-php-config=/usr/bin/php-config --with-mysql=mysqlnd

make & make install

重启php-fpm

/bin/systemctl restart php-fpm.service
