Nginx 平滑升级

1.下载想要升级的Nginx包

wget http://Nginx.org/download/Nginx-1.21.6.tar.gz

2.解压Nginx压缩包

tar -zxvf Nginx-1.21.6.tar.gz

3.进入Nginx-1.21.6文件夹下

cd Nginx-1.21.6

4.查看原版本Nginx 的配置

/usr/local/Nginx/sbin/Nginx -V

[root@localhost Nginx-1.21.6]# /usr/local/Nginx/sbin/Nginx -V
#Nginx的版本
Nginx version: Nginx/1.20.2
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
#Nginx的配置信息
configure arguments: --prefix=/usr/local/Nginx --with-http_ssl_module --with-pcre

5.配置新版Nginx

./configure --prefix=/usr/local/Nginx --with-http_ssl_module --with-pcre 

6.编译

make

7.移走原先的Nginx二进制文件

mv /usr/local/Nginx/sbin/Nginx /usr/local/Nginx/sbin/Nginx_old

8.替换新编译的文件到原Nginx的sbin目录下

cp objs/Nginx /usr/local/Nginx/sbin/

9.执行升级命令(在解压出的新版本的Nginx源文件目录下执行)

make upgrade

[root@localhost Nginx-1.21.6]# make upgrade
/usr/local/Nginx/sbin/Nginx -t
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
kill -USR2 cat /usr/local/Nginx/logs/Nginx.pid
sleep 1
test -f /usr/local/Nginx/logs/Nginx.pid.oldbin
kill -QUIT cat /usr/local/Nginx/logs/Nginx.pid.oldbin

10.查看是否升级成功

/usr/local/Nginx/sbin/Nginx -V

由原来的1.20.2已经升级到1.21.6
