这里已经显示问题。但我没有在意。
配置：./configure
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
依赖PCRE（PCRE(Perl Compatible Regular Expressions)是一个Perl库。包含 perl 兼容的正則表達式库。这些在运行正规表达式模式匹配时用与Perl 5相同的语法和语义是非常实用的。Boost太庞大了，使用boost regex后，程序的编译速度明显变慢。
測试了一下，相同一个程序，使用boost::regex编译时须要3秒，而使用pcre不到1秒。因此改用pcre来解决C语言中使用正則表達式的问题）库，下载地址：www.pcre.org/
指定库的位置：./configure --with-pare=/opt/pcre

查看系统时区：date -R
中国应该是+0800才对，但是显示的却是-0800
改动时区：
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
时区的信息存在/usr/share/zoneinfo/以下。本机的时区信息存在/etc/localtime
查看系统日期：date
发现日期也不正确，
改动日期：date -s 20141118
改动时间：date -s 19:16:55
把之前的文件删除：rm -rf nginx-1.7.4
再次解压：tar -zxvf nginx-1.7.4.tar.gz

这时显示结果就没问题了。
但这仅仅是攻克了警告的问题，但错误并没有解决。
