1. 下载nginx

下载地址：http://nginx.org/en/download.html
这里我们下载稳定版本

2. 安装nginx

直接解压刚刚下载的nginx-1.16.0.zip，解压后内容如下
注意解压后文件路径中不要有中文
会有如下异常

3. 启动

两中方式：
1）双击nginx.exe启动
2）命令行输入：start nginx.exe
验证是否成功启动，在浏览器中输入
127.0.0.1或者localhost
出现如下界面证明启动成功

启动

4. 配置

以下为nginx的初始配置

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

我们只需要修改以下部分

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;
    #此处添加
    upstream springboot {
     server 127.0.0.1:8110 max_fails=2 fail_timeout=5s;
    }
    #添加结束
    server {
        listen       80;
        server_name  localhost;
        #此处修改
        location / {
            proxy_pass http://springboot;
        }
        #修改结束
    }

5. 重启nginx

命令行输入：nginx.exe -t 验证配置文件是否正确
提示如下信息证明配置无误：

nginx: the configuration file C:\All\nginx-1.16.0/conf/nginx.conf syntax is ok
nginx: configuration file C:\All\nginx-1.16.0/conf/nginx.conf test is successful

命令行输入：nginx.exe -s reload 重启nginx
