nginx平滑升级

下载升级的版本软件包

# 官网下载地址，选择自己想要的版本
https://nginx.org/en/download.html

解压到新文件夹

cd /server
tar -zxvf nginx-1.26.2.tar.gz

编译

# 查询旧版本参数
[root@hcss-ecs-df46 nginx-1.26.2]# /usr/local/nginx/sbin/nginx -V
# 编译
[root@hcss-ecs-df46 nginx-1.26.2]# ./configure 添加上原来的参数（如果没有直接执行）
[root@hcss-ecs-df46 nginx-1.26.2]# make

备份和迁移

#旧版本备份
[root@hcss-ecs-df46 nginx-1.26.2]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx_old

#新版本迁移
[root@hcss-ecs-df46 nginx-1.26.2]# cp /server/nginx-1.26.2/objs/nginx /usr/local/nginx/sbin/

#测试新版本是否正常
[root@hcss-ecs-df46 nginx-1.26.2]#  /usr/local/nginx/sbin/nginx -t

#出现以下代表正常
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

给nginx发送平滑迁移信号

[root@hcss-ecs-df46 nginx-1.26.2]# kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`

查看nginx pid，会出现一个nginx.pid.oldbin

[root@hcss-ecs-df46 nginx-1.26.2]# ll /usr/local/nginx/logs/nginx.pid* 
-rw-r--r-- 1 root root 6 Dec 25 11:55 /usr/local/nginx/logs/nginx.pid
-rw-r--r-- 1 root root 6 Mar 29  2024 /usr/local/nginx/logs/nginx.pid.oldbin

关闭旧的Nginx进程

[root@hcss-ecs-df46 nginx-1.26.2]# kill -WINCH `cat /usr/local/nginx/logs/nginx.pid.oldbin`

此时不重载配置启动旧的工作进程

[root@hcss-ecs-df46 nginx-1.26.2]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid.oldbin`

结束工作进程，完成此次升级

[root@hcss-ecs-df46 nginx-1.26.2]# kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`

验证Nginx是否升级成功

[root@hcss-ecs-df46 nginx-1.26.2]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.26.2
