一、备份原配置文件

• 备份原配置文件到/root/nginx

  cp -r /usr/local/nginx/conf /root/nginx

二、编译nginx1.24

• 下载新版nginx

https://nginx.org/en/download.html

• 上传并解压nginx-1.24.0.tar.gz安装包

  tar -zxvf nginx-1.24.0.tar.gz

• 检查原nginx配置信息，新旧参数需保持一直

  root@redis:~# /usr/local/nginx/sbin/nginx -V
  nginx version: nginx/1.16.1
  built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
  built with OpenSSL 1.0.2k-fips  26 Jan 2017
  TLS SNI support enabled
  configure arguments: --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-file-aio --with-http_realip_module --add-module=../naxsi-0.56/naxsi_src/

• 进入nginx-1.24.0目录执行参数配置，安装目录为/etc/nginx，且启用了naxsi模块，根据实际情况配置

  ./configure --prefix=/etc/nginx --with-http_stub_status_module --with-http_ssl_module --with-file-aio --with-http_realip_module --add-module=/root/naxsi-0.56/naxsi_src

• 编译

  make

• 安装

  make install

• 检查是否安装成功

  root@redis:~# /etc/nginx/sbin/nginx -V
  nginx version: nginx/1.24.0
  built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
  built with OpenSSL 1.0.2k-fips  26 Jan 2017
  TLS SNI support enabled
  configure arguments: --prefix=/etc/nginx --with-http_stub_status_module --with-http_ssl_module --with-file-aio --with-http_realip_module --add-module=/root/naxsi-0.56/naxsi_src

三、替换旧配置

• 替换nginx主配置文件（只替换主配置文件即可，然后什么都不更改，就可以通过1.24运行原来的配置了）

  cp /root/nginx/conf/nginx.conf /etc/nginx/conf/

• 检查配置文件是否有错误

  root@redis:~#  /etc/nginx/sbin/nginx -t
  nginx: the configuration file /etc/nginx/conf/nginx.conf syntax is ok
  nginx: configuration file /etc/nginx/conf/nginx.conf test is successful

  四、配置软链接并加入systemctl管理

• 首先停止旧版nginx

  /usr/local/nginx/sbin/nginx -s stop

• 配置软链接到系统变量

  ln -s /etc/nginx/sbin/nginx /usr/sbin/nginx

• 配置新的nginx.conf文件，启用自定义PID

  root@redis:~#  vi /etc/nginx/conf/nginx.conf
  worker_processes  1;
  worker_rlimit_nofile 65535;
  pid /run/nginx.pid;     #创建这一行，启动nginx后会自动创建pid文件

• 配置nginx.service文件(注意nginx二进制文件目录即可)

  root@redis:~#   vi /etc/systemd/system/nginx.service 
  [Unit]
  Description=A high performance web server and a reverse proxy server
  Documentation=man:nginx(8)
  After=network-online.target remote-fs.target nss-lookup.target
  Wants=network-online.target
  
  [Service]
  Type=forking
  PIDFile=/run/nginx.pid
  ExecStartPre=/sbin/nginx -t -q -g 'daemon on; master_process on;'
  ExecStart=/sbin/nginx -g 'daemon on; master_process on;'
  ExecReload=/sbin/nginx -g 'daemon on; master_process on;' -s reload
  ExecStop=-/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid
  TimeoutStopSec=5
  KillMode=mixed
  
  [Install]
  WantedBy=multi-user.target

  五、启动1.24版nginx

• 启动新版nginx

  systemctl restart nginx

• 查看nginx状态

  root@redis:~# systemctl status nginx
  ● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/etc/systemd/system/nginx.service; disabled; vendor preset: disabled)
