Nginx平滑升级

查看当前 Nginx 编译参数

# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.15.7
built by gcc 4.8.2 20141223 (Red Hat 4.8.5-5) (GCC)
built with OpenSSL 1.21.1a  21 Nov 2016
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx

升级nginx

下载新版Nginx

cd ~
wget http://nginx.org/download/nginx-1.16.1.tar.gz
tar xzvf nginx-1.16.1.tar.gz

编译Nginx

• configure

cd nginx-1.16.1/
./configure --user=www --group=www --prefix=/usr/local/nginx

这里的 configure需跟上边 nginx -V 的编译参数一致。文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

• make

注意：这里一定 不要 执行 make install文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

替换旧的程序并重启

• 备份旧的执行程序文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

  mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

• 替换新的执行程序文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

  cp objs/nginx /usr/local/nginx/sbin/

• 检查nginx配置文件是否正常文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

  # /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

• 查看nginx版本文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

  /usr/local/nginx/sbin/nginx -V

  此时已经变成了新版本文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

重启

找到 nginx.pid 文件文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

kill -USR2 cat /usr/local/nginx/logs/nginx.pid

此时会生成一个新的文件：文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

/usr/local/nginx/logs/nginx.pid.oldbin

kill -QUIT cat /usr/local/nginx/logs/nginx.pid.oldbin

回滚方案

将备份的nginx还原并重启即可文章源自编程技术分享-https://mervyn.life/1db2b3f1.html

mv /usr/local/nginx/sbin/nginx.bak /usr/local/nginx/sbin/nginx
kill -USR2 cat /usr/local/nginx/logs/nginx.pid
kill -QUIT cat /usr/local/nginx/logs/nginx.pid.oldbin
