Nginx動態添加模塊 平滑升級
已經安裝好的Nginx動態添加模塊
說明：
已經安裝好的Nginx，需要添加一個未被編譯安裝的模塊，需要怎么弄呢？ 這里已安裝第三方nginx-rtmp-module模塊為例
nginx的模塊是需要重新編譯nginx，而不是像apache一樣配置文件引用.so
具體操作步驟：
（1）下載第三方擴展模塊nginx-rtmp-module
# cd /home/work/software/ # wget https://github.com/arut/nginx-rtmp-module/archive/master.zip # unzip master.zip # ls nginx-rtmp-module-master/
（2）查看nginx編譯安裝時安裝了哪些模塊
# /opt/nginx-1.9.5/sbin/nginx -V nginx version: nginx/1.9.5 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) built with OpenSSL 1.0.1g 7 Apr 2014 TLS SNI support enabled configure arguments: --prefix=/opt/nginx-1.9.5 --with-pcre=/home/work/software/pcre-8.38 --with-zlib=/home/work/software/zlib-1.2.8 --conf-path=/opt/nginx-1.9.5/conf/nginx.conf --pid-path=/opt/nginx-1.9.5/conf/nginx.pid --with-http_ssl_module --with-openssl=/home/work/software/openssl-1.0.1g --add-module=/home/work/software/headers-more-nginx-module-0.23 --add-module=/home/work/software/nginx-http-concat-master --with-http_gzip_static_module 可以看出編譯安裝使用了--prefix=/opt/nginx-1.9.5 --with-pcre=/home/work/software/pcre-8.38 --with-zlib=/home/work/software/zlib-1.2.8 --conf-path=/opt/nginx-1.9.5/conf/nginx.conf --pid-path=/opt/nginx-1.9.5/conf/nginx.pid --with-http_ssl_module --with-openssl=/home/work/software/openssl-1.0.1g --add-module=/home/work/software/headers-more-nginx-module-0.23 --add-module=/home/work/software/nginx-http-concat-master --with-http_gzip_static_module這些模塊。
（3）加入需要安裝的模塊，重新編譯，如這里添加–add-module=/home/work/software/nginx-rtmp-module-master
# cd /home/work/software/nginx-1.9.5 //進入到nginx之前安裝的目錄 # ./configure --prefix=/opt/nginx-1.9.5 --with-pcre=/home/work/software/pcre-8.38 --with-zlib=/home/work/software/zlib-1.2.8 --conf-path=/opt/nginx-1.9.5/conf/nginx.conf --pid-path=/opt/nginx-1.9.5/conf/nginx.pid --with-http_ssl_module --with-openssl=/home/work/software/openssl-1.0.1g --add-module=/home/work/software/headers-more-nginx-module-0.23 --add-module=/home/work/software/nginx-http-concat-master --with-http_gzip_static_module --add-module=/home/work/software/nginx-rtmp-module-master # make //注意：千萬不要make install，不然真的就GG了
（4）替換nginx二進制文件
# /etc/init.d/nginx stop # cp /opt/nginx-1.9.5/sbin/nginx /opt/nginx-1.9.5/sbin/nginx.bak # cp ./objs/nginx /opt/nginx-1.9.5/sbin/
（5）再次確認是否安裝成功
# /opt/nginx-1.9.5/sbin/nginx -V nginx version: nginx/1.9.5 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) built with OpenSSL 1.0.1g 7 Apr 2014 TLS SNI support enabled configure arguments: --prefix=/opt/nginx-1.9.5 --with-pcre=/home/work/software/pcre-8.38 --with-zlib=/home/work/software/zlib-1.2.8 --conf-path=/opt/nginx-1.9.5/conf/nginx.conf --pid-path=/opt/nginx-1.9.5/conf/nginx.pid --with-http_ssl_module --with-openssl=/home/work/software/openssl-1.0.1g --add-module=/home/work/software/headers-more-nginx-module-0.23 --add-module=/home/work/software/nginx-http-concat-master --with-http_gzip_static_module --add-module=/home/work/software/nginx-rtmp-module-master
至此、nginx就重新編譯添加模塊成功了。
