平滑升级Nginx

1.查看当前Nginx版本及configure信息

[root@base1 sbin]# ./nginx -V 
nginx version: nginx/1.16.0
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/wxqyh/component/nginx --user=nginx --group=nginx --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module --add-module=/wxqyh/component/nginx-sticky-module-ng

2.下载对应的版本(这里是nginx-1.16.1)到相关目录下，解压并进入解压后的目录

[root@base1 ~]# cd /usr/local/
[root@base1 nginx-1.16.1]# wget http://nginx.org/download/nginx-1.16.1.tar.gz
[root@base1 nginx-1.16.1]# wget https://www.openssl.org/source/openssl-1.1.0e.tar.gz
[root@base1 nginx-1.16.1]# tar xf openssl-1.1.0e.tar.gz
[root@base1nginx-1.16.1]# tar xf nginx-1.16.1.tar.gz
[root@base1 nginx-1.16.1]# cd nginx-1.16.1

3.查看nginx版本的时候，configure后面有一大串模块，这也是你第一次安装nginx时所指定的模块，升级的时候也要同时指定，也可以添加其他模块

[root@base1 nginx-1.16.1]# ./configure --prefix=/wxqyh/component/nginx --user=nginx --group=nginx --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module --add-module=/wxqyh/component/nginx-sticky-module-ng

[root@base1 nginx-1.16.1]# make

make完以后，不需要执行make install，否则会覆盖安装，nginx服务会出现各种问题

不中断nginx web服务器的正常运行称之为平滑升级，先重命名之前的nginx二进制文件

[root@base1 nginx-1.16.1]# mv /wxqyh/component/nginx/sbin/nginx /wxqyh/component/nginx/sbin/nginx.bak

拷贝刚编译新生产的Nginx二进制文件到/wxqyh/component/nginx/sbin/目录

[root@base1 nginx-1.16.1]# cp /wxqyh/component/nginx-1.16.1/objs/nginx /wxqyh/component/nginx/sbin/

4.开始执行升级命令

[root@base1 nginx-1.16.1]# make upgrade

自动提示：
/wxqyh/component/nginx/sbin/nginx -t
nginx: the configuration file /wxqyh/component/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /wxqyh/component/nginx/conf/nginx.conf test is successful
kill -USR2 `cat /wxqyh/component/nginx/logs/nginx.pid`
sleep 1
test -f /wxqyh/component/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /wxqyh/componentnginx/logs/nginx.pid.oldbin`

查看nginx版本信息

[root@base1 sbin]# ./nginx -V 
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)

configure arguments: --prefix=/wxqyh/component/nginx --user=nginx --group=nginx --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module --add-module=/wxqyh/component/nginx-sticky-module-ng
