nginx编译openssl版本兼容或排错修复

　　在nginx-0.7.59之前，系统自带的openssl版本低于openssl-0.9.8e时编译时报错如下：

　　objs/ngx_modules.o \ -lcrypt -lpcre -lzobjs/src/http/ngx_http_file_cache.o: In function `ngx_http_file_cache_create_key':/EBS/soft-backup/nginx-0.7.58/src/http/ngx_http_file_cache.c:128: undefined reference to `MD5_Init'/EBS/soft-backup/nginx-0.7.58/src/http/ngx_http_file_cache.c:138: undefined reference to `MD5_Update'/EBS/soft-backup/nginx-0.7.58/src/http/ngx_http_file_cache.c:145: undefined reference to `MD5_Final'collect2: ld returned 1 exit statusmake[1]: *** [objs/nginx] Error 1make[1]: Leaving directory `/EBS/soft-backup/nginx-0.7.58'make: *** [build] Error 2the change log：Changes with nginx 0.7.59 25 May 2009 *) Feature: the “proxy_cache_methods“ and “fastcgi_cache_methods“ directives. *) Bugfix: socket leak; the bug had appeared in 0.7.25.

　　先确定好 openssl 的版本 以及跟nginx的版本匹配，排除一个可能

　　这里有最新版本的

　　l版本的http://u.xunzai.com/fileview_222768.html

　　然后我发现在Makefile 里面，nginx 都是依旧的默认要手动安装，当然不排除linuxtone里面的roin 教的方法，原理就是要搜索 ldconfig 的目录下的libssl.so

　　ln -sf openssl/lib/libsslXXXX /usr/lib 手动整理库链接

　　知道归知道,但是对于Makefile不熟悉没找出调用的结构体,而如果有需要(就是无法使用ldconfig或者其他原因)就可以手改Makefile 的目录

　　~/soft/openssl-0.9.8l/openssl/include/openssl/ssl.h: objs/Makefile

　　cd ~/soft/openssl-0.9.8l \

　　&& $(MAKE) clean \

　　&& ./config

　　--prefix=/home/yuan520/soft/nginx-0.7.64/~/soft/openssl-0.9.8l/openssl 这里的路径是错误的,具体按需修改,顺利指向你的openssl目录即可

　　no-shared no-threads \ ---虽然说使用挂了no-shared 理论上会不和其他版本的openssl冲突,但是实际上我试验了却不行,依旧需要处理好版本兼容的问题

　　&& $(MAKE) \

　　&& $(MAKE) install
