nginx版本的平滑升级（无坑）

好文分享~

查看当前Nginx版本信息

[root@web ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.10.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) 
built with OpenSSL 1.1.0e  16 Feb 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-pcre --with-openssl=/tmp/openssl-1.1.0e --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_image_filter_module --with-mail --with-threads --with-mail_ssl_module --with-stream_ssl_module
下载nginx-1.16.1版本到/usr/local/下，解压并进入解压后的目录

[root@nginx ~]# cd    /usr/local/
[root@nginx nginx-1.16.1]# wget http://nginx.org/download/nginx-1.16.1.tar.gz
[root@nginx nginx-1.16.1]# wget https://www.openssl.org/source/openssl-1.1.0e.tar.gz
[root@nginx nginx-1.16.1]# tar xf openssl-1.1.0e.tar.gz
[root@nginx nginx-1.16.1]# tar xf nginx-1.16.1.tar.gz
[root@nginx nginx-1.16.1]# cd nginx-1.16.1
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@nginx nginx-1.16.1]# ./configure \（注意 \ 是向下连接符的意思，不要在这里就进行两次回车，继续写你需要的相关编译参数，小坑这里）
  --prefix=/usr/local/nginx \
  --user=nginx \
  --group=nginx \
  --with-pcre \
  --with-openssl=/tmp/openssl-1.1.0e \
  --with-http_ssl_module \
  --with-http_v2_module \
  --with-http_realip_module \
  --with-http_addition_module \
  --with-http_sub_module \
  --with-http_dav_module \
  --with-http_flv_module \
  --with-http_mp4_module \
  --with-http_gunzip_module \
  --with-http_gzip_static_module \
  --with-http_random_index_module \
  --with-http_secure_link_module \
  --with-http_stub_status_module \
  --with-http_auth_request_module \
  --with-http_image_filter_module \
  --with-mail \
  --with-threads \
  --with-mail_ssl_module \
  --with-stream_ssl_module \
 && 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@nginx nginx-1.16.1]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
拷贝刚编译新生产的Nginx二进制文件到/usr/local/nginx/sbin/目录

[root@nginx nginx-1.16.1]# cp /usr/local/nginx-1.16.1/objs/nginx /usr/local/nginx/sbin/
开始执行升级命令

[root@web nginx-1.16.1]# make upgrade

自动提示：
/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`
