CentOS 7 Nginx1.12.2平滑升级到新版本nginx-1.21.5

查看当前Nginx版本信息

[root@web ~]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.12.2 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 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-1.21.5版本到/usr/local/下，解压并进入解压后的目录

[root@nginx ~]# cd /usr/local/ [root@nginx ~]# wget http://nginx.org/download/nginx-1.21.5.tar.gz [root@nginx ~]# tar xf nginx-1.21.5.tar.gz [root@nginx ~]# cd nginx-1.21.5

配置nginx

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-1.21.5]# ./configure \ --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-1.21.5]# 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-1.21.5]# cp /usr/local/nginx-1.21.5/objs/nginx /usr/local/nginx/sbin/

开始执行升级命令

[root@web nginx-1.21.5]# 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`

查看nginx版本信息

[root@web nginx-1.13.3]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.21.5 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

注意：

报错：nginx unknown directive "stream"

nginx默认安装的时候没有加载stream模块

需要重新对源文件进行编译、安装，通过添加--with-stream参数指定安装stream模块

./configure --with-stream

make & make install

再次检查nginx.conf配置文件，确认配置无语法错误后，再次尝试启动服务。

nginx -t 检查配置文件是否正确

nginx -c 指定启动的配置文件
