1 进入nginx安装目录，查看nginx版本及其编译参数：
[root@localhost nginx]# ./nginx -V
nginx version: nginx/1.8.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)
built with OpenSSL 1.0.1c 10 May 2012
TLS SNI support enabled
configure arguments: --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --with-pcre=../pcre-8.37 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-1.0.1c --with-http_stub_status_module --user=nginx --group=nginx
[root@localhost nginx]#
2 进入nginx的源码目录：
[root@localhost src]# ls
nginx-1.8.0 openssl-1.0.1c pcre-8.37 zlib-1.2.8
nginx-1.8.0.tar.gz openssl-1.0.1c.tar.gz pcre-8.37.tar.gz zlib-1.2.8.tar.gz
[root@localhost src]# pwd
/usr/local/src
[root@localhost src]# cd nginx-1.8.0
[root@localhost nginx-1.8.0]# ls
auto CHANGES CHANGES.ru conf configure contrib html LICENSE Makefile man objs README src
[root@localhost nginx-1.8.0]#
3 以下是重新编译的代码和模块：
./configure --sbin-path=/usr/local/nginx/nginx \
--conf-path=/usr/local/nginx/nginx.conf \
--pid-path=/usr/local/nginx/nginx.pid \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_stub_status_module \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_auth_request_module \
--with-mail \
--with-mail_ssl_module \
--with-file-aio \
--with-http_spdy_module \
--with-ipv6 \
--with-pcre=../pcre-8.37 \
--with-zlib=../zlib-1.2.8 \
--with-openssl=../openssl-1.0.1c \
--user=nginx \
--group=nginx;
截图如下：
详细参数请看官网：http://nginx.org/en/docs/configure.html
4 编译：
make （注意：千万不要make install）
5 make完成之后再当前目录下的objs目录下就多了个nginx,这个就是新版本的程序了
6 备份旧的nginx程序
[root@localhost objs]# cp /usr/local/nginx/nginx /usr/local/nginx/nginx.bak
[root@localhost objs]# cd /usr/local/nginx/
[root@localhost nginx]# ls
client_body_temp fastcgi_temp mime.types.default sbin uwsgi_temp
conf html nginx scgi_params win-utf
fastcgi.conf koi-utf nginx.bak scgi_params.default
fastcgi.conf.default koi-win nginx.conf scgi_temp
fastcgi_params logs nginx.conf.default uwsgi_params
fastcgi_params.default mime.types proxy_temp uwsgi_params.default
[root@localhost nginx]#
6 把新的nginx程序覆盖旧的
[root@localhost nginx-1.8.0]# ls
auto CHANGES CHANGES.ru conf configure contrib html LICENSE Makefile man objs README src
[root@localhost nginx-1.8.0]# cp objs/nginx /usr/local/nginx/nginx
cp：是否覆盖"/usr/local/nginx/nginx"？ y
[root@localhost nginx-1.8.0]#
7 测试新的nginx程序是否正确
[root@localhost nginx-1.8.0]#/usr/local/nginx/nginx -t
8 平滑重启nginx
/usr/local/nginx/nginx –s reload
9 查看nginx版本及其编译参数：
/usr/local/nginx/nginx –V
