location ~* ^/download/.*\.(php|php5)$
{
deny all;
}

location ~* ^/download/.*\.(php|php5)$

{

deny all;

}

2、禁止多个目录执行php [crayon-5f6f649a20 … 阅读全文

README.md文件中有写

Allocator

---------

Selecting a non-default memory allocator when building Redis is done by setting

the `MALLOC` environment variable. Redis is compiled and linked against libc

malloc by default, with the exception of jemalloc being the default on Linux

systems. This default was picked because jemalloc has proven to have fewer

fragmentation problems than libc malloc.

To force compiling against libc malloc, use:

% make MALLOC=libc

To compile against jemalloc on Mac OS X systems, use:

% make MALLOC=jemalloc
