The following PHP extensions are missing:sockets

在配置安装Cacti，全部配置好打开安装界面突然报错：

别急，PHP扩展没好，重新编译加上--enable-sockets这个就好了，如下：

./configure --prefix=/usr/local/php \

--with-mysql=/usr/local/mysql \

--with-apxs2=/usr/local/apache/bin/apxs \

--with-zlib  \

--with-libxml-dir=/usr/lib \

--enable-sockets
