centos下nginx配置及环境变量配置

菜鸟教程的配置教程
跟着上面的配置就行。
配置环境变量：
在根目录下运行 vim /etc/profile
在最后面加入：

export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin

然后运行：

source /etc/profile 

让配置文件生效，输入nginx -v，出现版本信息就代表环境变量配置成功。

进入nginx目录的conf，对nginx.conf进行修改。
注意文件路径

一个https文件配置

## Basic reverse proxy server ##
upstream pay {
    server 127.0.0.1:10000;
}
server {
    listen 443;
    server_name xx.xx.xx;  # localhost修改为您证书绑定的域名。
    ssl on;   #设置为on启用SSL功能。
   # root html;
    #index index.html index.htm;
    ssl_certificate https_file/xx.xx.xx.pem;   #将domain name.pem替换成您证书的文件名。
    ssl_certificate_key https_file/xx.xx.xx.key;   #将domain name.key替换成您证书的密钥文件名。
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;  #使用此加密套件。
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;   #使用该协议进行配置。
    ssl_prefer_server_ciphers on;
    location / {
        proxy_pass  http://pay;
                    #Proxy Settings
        proxy_redirect     off;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;

        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;
        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;
     #   root html;   #站点目录。
      #  index index.html index.htm;
    }
}
server {
    listen 80;
    server_name  xx.xx.xx;
    rewrite ^(.*) https://$host$1 permanent;
    access_log  /usr/local/webserver/nginx/logs/pay.access.log  main;
    error_log  /usr/local/webserver/nginx/logs/pay.error.log;
    #root   html;
    #index  index.html index.htm index.php;
    location / {
        
    }
}

记得修改文件路径和域名。安全组开放对应端口，域名解析到该服务器，可以申请到免费的ssl证书，如果没有证书，删掉ssl相关配置即可。
