[系统运维]nginx平滑升级以及配置文件

nginx平滑升级和添加新功能

1.下载新版本的nginx

[root@nginx ~]# wget https://nginx.org/download/nginx-1.22.0.tar.gz
[root@nginx ~]# ls
123  anaconda-ks.cfg  guazai  lv0  nginx-1.20.2  nginx-1.20.2.tar.gz  nginx-1.22.0.tar.gz  nginx_module_echo

2.获取原版本nginx的编译信息

//获取原版本nginx的编译信息
[root@nginx ~]# nginx -V
nginx version: nginx/1.20.2
built by gcc 8.5.0 20210514 (Red Hat 8.5.0-4) (GCC)
built with OpenSSL 1.1.1k  FIPS 25 Mar 2021
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_image_filter_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log

3.配置新版本和功能

//下载工具来拉取gitee仓库的功能
[root@nginx ~]# dnf -y install git
[root@nginx ~]# git clone https://gitee.com/wujunze/nginx_module_echo.git
Cloning into 'nginx_module_echo'...
remote: Enumerating objects: 80, done.
remote: Total 80 (delta 0), reused 0 (delta 0), pack-reused 80
Unpacking objects: 100% (80/80), 14.32 KiB | 977.00 KiB/s, done.
[root@nginx ~]# ls
123  anaconda-ks.cfg  guazai  lv0  nginx-1.20.2  nginx-1.20.2.tar.gz  nginx_module_echo

//解压
[root@nginx ~]# tar xf nginx-1.22.0.tar.gz
[root@nginx ~]# ls
123  anaconda-ks.cfg  guazai  lv0  nginx-1.20.2  nginx-1.20.2.tar.gz  nginx-1.22.0  nginx-1.22.0.tar.gz  nginx_module_echo
[root@nginx ~]# cd nginx-1.22.0/
[root@nginx nginx-1.22.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_image_filter_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=../nginx_module_echo

4.make进行编译，千万不能make install安装

[root@nginx nginx-1.22.0]# make

5.进行替换

//将老版本的nginx备份，然后杀掉nginx进程，将新版本的nginx强行复制到老版本的位置，然后启动nginx服务。
[root@nginx nginx-1.22.0]# cp /usr/local/nginx/sbin/nginx{,.bak};pkill nginx;\cp objs/nginx /usr/local/nginx/sbin/;systemctl start nginx
[root@nginx nginx-1.22.0]# nginx -V
nginx version: nginx/1.22.0
built by gcc 8.5.0 20210514 (Red Hat 8.5.0-4) (GCC)
built with OpenSSL 1.1.1k  FIPS 25 Mar 2021
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_image_filter_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=../nginx_module_echo

6.nginx的配置文件详解

主配置文件：/usr/local/nginx/conf/nginx.conf

• 默认启动nginx时，使用的配置文件是：安装路径/conf/nginx.conf文件
• 可以在启动nginx时通过-c选项来指定要读取的配置文件
