Nginx 平滑升级

Nginx 平滑升级

nginx/1.20.1 --->1.22.1

1、查看原编译参数

nginx -V
--------------------------------------------
nginx version: nginx/1.20.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --with-http_stub_status_module --with-http_ssl_modul

2、解压源码进行编译

1）解压

tar -zxvf nginx-1.22.1.tar.gz

2）配置编译

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make

3、备份替换nginx文件

1）备份原来 nginx 二进制文件

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old

2) 复制新的nginx二进制文件

cp /data/software/nginx-1.22.1/objs/nginx /usr/local/nginx/sbin

3）测试nginx是否正常

nginx -t

4） 平滑升级

kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
