nginx反向代理oracle+负载均衡配置

通过TCP协议访问oracle

软件基本信息

nginx版本：1.17.4
nginx所在服务器ip:192.168.21.100
oracleA信息：oracle11g,ip:192.168.21.213:1521
oracleB信息：oracle11g,ip:192.168.21.214:1521

反向代理oracle

#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;
}


stream {

    upstream oracle {
        server 192.168.21.213:1521 weight=1 max_fails=2 fail_timeout=30s;   #原oracle地址
    }

 server {
        listen       3335;# 反向代理后监听的端口,nginx启动后访问192.168.21.100:3335就可以访问到oracleA
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass oracle;
    }
}

oracle负载均衡

主要用于查询的时候进行负载均衡，oracleA和oracleB两个库内容相关。

#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;
}


stream {

    upstream oracle {
        server 192.168.21.213:1521 weight=1 max_fails=2 fail_timeout=30s;   #原oracle地址
        server 192.168.21.214:1521 weight=2 max_fails=2 fail_timeout=30s;
    }

 server {
        listen 3335 so_keepalive=on; #so_keepalive,会话保持，防止查询飘走
        proxy_pass oracle;
    }
}
