Nginx安装配置详解、Nginx配置https反向代理示例
Nginx 安装
软硬件环境：CentOS 7.6_64位
安装依赖环境
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel pcre pcre-devel
查看pcre版本
[root@yaenli pcre]# pcre-config --version
安装Nginx
-
下载Nginx安装包：手动从官网地址 nginx: download，下载安装包上传至服务器目录或者采用如下命令
[root@yaenli src]# cd /usr/local/src/ [root@yaenli src]# wget http://nginx.org/download/nginx-1.22.0.tar.gz -
解压安装包
[root@yaenli src]# tar zxvf nginx-1.22.0.tar.gz -
进入安装目录执行配置命令创建makefile文件
[root@yaenli src]# cd nginx-1.22.0 ./configure \ --prefix=/usr/local/nginx \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-http_v2_module \ --with-pcre注1：\ 代表在命令行中换行，用于提高可读性
注2：configure参数官方说明：Building nginx from Sources
部分模块说明：（后续可以根据需要依据此参数增减模块）
http_ssl_module：用于支持https
http_v2_module：用于支持HTTP/2
配置结果：
Configuration summary + using system PCRE library + using system OpenSSL library + using system zlib library nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/nginx/sbin/nginx" nginx modules path: "/usr/local/nginx/modules" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp" -
编译安装
[root@yaenli nginx-1.22.0]# make && make install -
查看Nginx版本
[root@yaenli nginx-1.22.0]# /usr/local/nginx/sbin/nginx -V至此，安装完成。
Nginx 配置
使用NGINXConfig完成配置工作。
NGINXConfig是一个在线的可视化的Nginx配置工具，地址：NGINXConfig | DigitalOcean
使用配置方法：
-
进入你的 NGINX服务器上的配置目录:
cd /usr/local/nginx/conf -
创建当前NGINX配置的备份:
tar -czvf nginx_$(date +'%F_%H-%M-%S').tar.gz nginx.conf sites-available/ sites-enabled/ nginxconfig.io/ -
使用tar解压新的配置文件（从NGINXConfig上下载）
tar -xzvf nginxconfig.io-example.com.tar.gz | xargs chmod 0644 -
服务器上运行此命令生成Diffie-Hellman keys:
openssl dhparam -out /usr/local/nginx/conf/dhparam.pem 2048 -
重新加载NGINX以载入新的配置:
sudo nginx -t && sudo systemctl reload nginx
https的反向代理配置示例
单应用的https反向代理，采用模块化配置方法：Nginx配置示例
