在已安装nginx情况下安装nginx模块
nginx第三方模块安装方法：
代码如下:./configure --prefix=/你的安装目录 --add-module=/第三方模块目录
1、.查看nginx编译安装时的命令，安装了哪些模块
代码如下:#/usr/local/webserver/nginx/sbin/nginx -V
2、切换到root用户
代码如下:#su root
3、在已安装nginx情况下安装nginx模块(username为系统用户名)
代码如下:# sudo ./configure --prefix=/usr/local/nginx --with-pcre=/home/username/下载/nginx/pcre-8.32 --with-zlib=/home/username/下载/nginx/zlib-1.2.8 --with-openssl=/home/username/下载/nginx/openssl-1.0.2a --add-module=/home/username/下载/nginx/nginx_mod_h264_streaming-2.2.7
# make
# cp objs/nginx /usr/local/nginx/sbin/nginx
#. /usr/local/nginx-1.4.1/sbin/nginx
相比在未安装nginx的情况下安装nginx第三方模块，多了一步覆盖nginx文件.
如果在./configure前不加 sudo，会出现以下错误提示：
./configure: 45: auto/init: cannot create Makefile: Permission denied
./configure: 16: ./configure: cannot create objs/ngx_auto_headers.h: Permission denied
./configure: 17: ./configure: cannot create objs/autoconf.err: Permission denied

---------------------------------------
解决方案：
sudo ./configure --prefix=/usr/local/nginx --with-pcre=/home/user/下载/nginx/pcre-8.32 --with-zlib=/home/user/下载/nginx/zlib-1.2.8 --with-openssl=/home/user/下载/nginx/openssl-1.0.2a --add-module=/home/user/下载/nginx/nginx_mod_h264_streaming-2.2.7
4、总结
在已安装nginx情况下安装第三方模块实际上是使用–add-module重新安装一次nginx，不要make install而是直接把编译目录下objs/nginx文件直接覆盖旧的nginx文件.如果你需要安装多个nginx第三方模块,你只需要多指定几个相应的–add-module即可.
备注：重新编译的时候，记得一定要把以前编译过的模块一同加到configure参数里面.
