linux 升级 nginx版本

一、准备

1. 新建一个目录存放安装包。可以放在/root/nginx 。

2. 升级前对原nginx的配置文件 ‘ nginx.conf ’  做下备份。

3. 先查看下当前nginx安装位置和版本号。

ps -ef | grep nginx

root     115149      1  0 14:18 ?        00:00:00 nginx: master process /usr/local/nginx-1.13.4/sbin/nginx
nobody   115150 115149  0 14:18 ?        00:00:00 nginx: worker process             
root     115208 110517  0 14:50 pts/0    00:00:00 grep nginx

/usr/local/nginx-1.13.4/sbin/nginx -V

nginx version: nginx/1.13.4
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx-1.13.4 --with-http_stub_status_module --with-http_ssl_module

二、开始升级 gogogo ~

1. 解压下载的新版本nginx文件

cd /root/nginx

tar -zxvf nginx-1.16.1.tar.gz

cd nginx-1.16.1

./configure --prefix=/usr/local/nginx-1.13.4 --with-http_stub_status_module --with-http_ssl_module&&make   【nginx-1.13.4这个文件夹是我之前版本的文件夹名称，按照自己的实际情况写哦，直接粘贴可能会有问题】

2. 开始替换新老版本的执行文件

cd /usr/local/nginx-1.13.4/sbin

mv nginx nginx.old

cp  -r /root/nginx/nginx-1.13.4/objs/nginx .

3. 查看下nginx配置文件是否正确

/usr/local/nginx-1.13.4/sbin/nginx -t

执行后的提示信息：

nginx: the configuration file /usr/local/nginx-1.13.4/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx-1.13.4/conf/nginx.conf test is successful
[root@wcce sbin]# kill -USR2 `cat  /usr/local/nginx-1.13.4/logs/nginx.pid`  
nginx-1.13.4/

4. 开始升级nginx版本

kill -USR2 `cat  /usr/local/nginx-1.13.4/logs/nginx.pid`

5. 将旧版本nginx的pid改为nginx.pid.oldbin

cd /usr/local/nginx-1.13.4/logs

ls -lit nginx.pid.oldbin

6. 退出旧版本nginx

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

7. 最后查看下nginx的版本号

/usr/local/nginx/sbin/nginx -v

nginx version: nginx/1.16.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx-1.13.4 --with-http_stub_status_module --with-http_ssl_module

成功升级！
