在美国vps上编译vps遇到一个报错：Cannot allocate memory
一、编译php时遇到virtual memory exhausted: Cannot allocate memory解决方法如下：
|
0 1 2 |
./configure --enable-opcache --prefix=/byrd/server/php-5.5.11 --with-mysql=/usr/local/mysql/ --with-iconv-dir=/usr/local/libiconv --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-short-tags --enable-static --with-xsl --with-fpm-user=www --with-fpm-group=www --enable-ftp 增加这个参数：--disable-fileinfo |
二、在执行free -m的是时候提示Cannot allocate memory:
