【推荐】Nginx基础知识之————多模块(非覆盖安装、RTMP在线人数实例安装测试)

sudo git clone https://github.com/arut/nginx-rtmp-module.git 

tar.gz 这种格式是我使用得最多的压缩格式。它在压缩时不会占用太多CPU的，而且可以得到一个非常理想的压缩率。使用下面这种格式去压缩一个目录：
# tar -zcvf archive_name.tar.gz directory_to_compress
解压缩：
# tar -zxvf archive_name.tar.gz

./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.
