# 查看nginx安装了哪些插件

nginx -V

# 停止并卸载老的nginx

systemctl stop nginx
 
ps -ef|grep nginx

# 备份老的配置

find / -name "nginx"

# 下载nginx源码，并解压，进入解压目录
 

wget http://nginx.org/download/nginx-1.22.0.tar.gz
tar -zxvf nginx-1.22.0.tar.gz
cd nginx-1.22.0

修改源码配置

vi +13 src/core/nginx.h
 
#define NGINX_VERSION      "8.8.8"
 
#define NGINX_VER          "  /" NGINX_VERSION
 
 
vi +49 src/http/ngx_http_header_filter_module.c
 
static u_char ngx_http_server_string[] = "Server:   " CRLF;
 
 
vi +36 src/http/ngx_http_special_response.c
 
"
  " CRLF

编译中报错修复：

yum -y install pcre-devel
