配置

--下载nginx
wget http://nginx.org/download/nginx-1.18.0.tar.gz

--解压源码包
tar zxf nginx-1.18.0.tar.gz
cd /nginx-1.18.0

修改nginx源码

将下载后的nginx源码解压，需要对以下几个文件做出修改。这里我们演示将nginx服务器名称修改为`end`

--文件一：src/core/nginx.h

#define NGINX_VER          "nginx/" NGINX_VERSION
//修改为
#define NGINX_VER          "end/" NGINX_VERSION

#define NGINX_VAR          "NGINX"
//修改为
#define NGINX_VAR          "END"

--文件二：src/http/ngx_http_header_filter_module.c

static u_char ngx_http_server_string[] = "Server: nginx" CRLF;
//修改为
static u_char ngx_http_server_string[] = "Server: end" CRLF;

--文件三：src/http/ngx_http_special_response.c
"<hr><center>nginx</center>" CRLF
//修改为
"<hr><center>end</center>" CRLF

--文件四：src/http/v2/ngx_http_v2_filter_module.c
"http2 output header: \"server: nginx\"");
//修改为
"http2 output header: \"server: end\"");

通过修改上面4个文件,已经`nginx`服务器名修改为了end,如果不想去找到文件一个一个修改,也可以使用sed命令直接替换

--执行更名操作
sed -i "s#\"NGINX\"#\"end\"#" src/core/nginx.h
sed -i "s#\"nginx/\"#\"END/\"#" src/core/nginx.h
sed -i "s#Server: nginx#Server: end#" src/http/ngx_http_header_filter_module.c
sed -i "s#\"<hr><center>nginx<\/center>\"#\"<hr><center>end<\/center>\"#" src/http/ngx_http_special_response.c
sed -i "s#server: nginx#server: end#"

验证

修改完毕后，需要将源码重新编译，如何编译`nginx`这篇文章不做描述，具体请网上搜索。我们可以使用`curl`命令来测试是否修改成功，执行测试命令`curl -I https://www.endvv.com返回的结果如下，可以看到Server那里已经变为`END`
