升级
实验环境准备
原nginx
版本:1.24
需要升级到
的版本:1.26
需要的包:echo-nginx-module-0.63.tar.gz
,nginx-1.24.0.tar.gz
,nginx-1.26.2.tar.gz
[ root@nginx ~]

测试内容准备
[ root@nginx ~]
[ root@nginx html]
[ root@nginx html]
hello world
while true ; do curl 172.25 .254.100; sleep 1 ; done
实验要求
在升级的过程中,原nginx提供的web服务不能中断

实验步骤
1.解压包
[ root@nginx ~]
[ root@nginx ~]
2.检测1.26版本的环境
[ root@nginx ~]
[ root@nginx nginx-1.26.2]
> --user = nginx \
> --group = nginx \
> --with-http_ssl_module \
> --with-http_v2_module \
> --with-http_realip_module \
> --with-http_stub_status_module \
> --with-http_gzip_static_module \
> --with-pcre \
> --with-stream \
> --with-stream_ssl_module
> --add-module= /root/echo-nginx-module-0.63
3.make编译
[ root@nginx nginx-1.26.2]
4.备份之前的nginx
启动脚本
[ root@nginx ~]
[ root@nginx sbin]
nginx
[ root@nginx sbin]
[ root@nginx sbin]
nginx nginx.old
5.将1.26中的nginx启动脚本覆盖掉1.24中的
[ root@nginx sbin]
6.kill -USR2 旧主进程pid
使用kill -USR2
启动一个新的
,只启动,不监听端口

3.备份nginx
启动脚本
[ root@nginx sbin]
nginx nginx.old
[ root@nginx sbin]
[ root@nginx sbin]
nginx nginx.new nginx.old
4.nginx.old
覆盖nginx
[ root@nginx sbin]
[ root@nginx sbin]
nginx nginx.new nginx.old
5.kill -9 新主进程pid
