wordpress必要的PHP扩展

若你的服务器上只有一个wordpress网站，那么我们就没必要开启过多的PHP扩展，用下面的编译参数就能把wordpress跑起来，其实configure的参数就是在开启或者关闭一些PHP的附加功能，功能少，运行起来占用的内存就小。

./configure --prefix=/usr/local/php \
--enable-opcache \
--with-config-file-path=/usr/local/php/etc \
--with-curl \
--enable-fpm \
--enable-ftp \
--with-gd \
--with-iconv \
--enable-mbstring \
--with-mysqli=mysqlnd \
--with-openssl \
--enable-static \
--enable-sockets \
--enable-inline-optimization \
--with-zlib \
--disable-ipv6 \
--disable-fileinfo \
--disable-debug

make
make install
