nginx代理mysql(window下)

1 概述

有时候项目中需要统一数据库配置地址，但是做政府项目很多是内网环境，数据库的地址无法统一，但是又不好每个环境单独配置数据库，这时候可以使用nginx代理成统一的数据库地址。

1.1 下载ngnx

没啥好说的 自行百度下载解压关键是配置信息，目前本人用的是nginx-1.16.1版本的下载链接

1.2 配置

需要在解压后的nginx.conf文件的同级目录下创建一个mycon文件夹，并创建db.conf文件
db.conf配置

server {
     
    #注意端口不能跟mysql监听的一样
    listen 3307; 
    proxy_pass db;
}
# 负载的实际端口和地址  也可以其他能访问的地址，不一定是本机
upstream db {
     
    server 127.0.0.1:3306;
}

nginx完整配置
千万不能放在http标签里面，stream 和http 标签同级

#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;
}

# 数据库代理 这个就是代理的配置 其他的就是默认的
stream{
     
    include myconf/db.conf;
}

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

        #    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;
    #    }
    #}
}

1.3 nginx重启暂停命令

1. 启动：双击nginx.exe
2. 快速停止或关闭Nginx：

nginx.exe -s stop

3. 配置文件修改重装载命令：

nginx.exe -s reload
