Nginx 安装配置

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

  1. 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

  2. 解压安装包

    [root@yaenli src]# tar zxvf nginx-1.22.0.tar.gz

  3. 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"

  4. 编译安装

    [root@yaenli nginx-1.22.0]# make && make install

  5. 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：

  1. 进入你的 NGINX服务器上的配置目录:

    cd /usr/local/nginx/conf

  2. 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/

  3. 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

  4. 服务器上运行此命令生成Diffie-Hellman keys:

    openssl dhparam -out /usr/local/nginx/conf/dhparam.pem 2048

  5. 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
