一、下载nginx

管网镜像
http://nginx.org/download/

下载时需要注意：
nginx1.9.0版本后，才支持--with-stream 模块

获取nginx，官方地址

wget http://nginx.org/download/nginx-1.17.9.tar.gz

二、环境准备

安装之前必先确认是否安装 gcc 环境（gcc -v），如果没有安装，用root用户执行以下命令进行安装

yum install -y gcc 

安装依赖

yum -y install pcre-devel openssl openssl-devel library

本文采用非root用户编译安装，新建安装用户fym

三、编译安装

1.解压

tar -zxvf nginx-1.17.9.tar.gz

2.配置
进入到解压目录，开启端口转发：--with-stream --with-stream_ssl_module

./configure  --prefix=/home/fym/nginx  --sbin-path=/home/fym/nginx/sbin/nginx --conf-path=/home/fym/nginx/conf/nginx.conf --error-log-path=/home/fym/nginx/log/error.log  --http-log-path=/home/fym/nginx/log/access.log  --pid-path=/home/fym/nginx/nginx.pid --lock-path=/home/fym/nginx/nginx.lock  --user=fym --group=fym --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/home/fym/nginx/tmp/client/ --http-proxy-temp-path=/home/fym/nginx/tmp/proxy/ --http-fastcgi-temp-path=/home/fym/nginx/tmp/fcgi/ --http-uwsgi-temp-path=/home/fym/nginx/tmp/uwsgi --http-scgi-temp-path=/home/fym/nginx/tmp/scgi --with-pcre --with-stream --with-stream_ssl_module

3.编译安装

make & make install

四、配置

worker_processes  1;

events {
    worker_connections  1024;
}

# 此为TCP转发请求
stream {
    # 后端指向 server 的 28017 端口 stream_mongo 组
    upstream stream_mongo {
         server 192.168.62.15:28017;

    }
    
    # 后端指向 server 的 8090 端口 cns组
    upstream stream_mysql {
         server 192.168.62.15:3306;
         server 192.168.62.37:3306;
    }

    #}
    
    server {
        # 本机监听端口 28017 
        listen                28017;
        
        # 请求抛给 stream_mongo 组
        proxy_pass            stream_mongo;
    }
    server {
        # 本机监听端口 3306 
        listen                3306;
        
        # 请求抛给 stream_mysql 组
        proxy_pass            stream_mysql;
    }      
}

        #location ~ /\.ht {
        #    deny  all;

五、常用指令

#启动
./sbin/nginx -c ./conf/nginx.conf
#停止
./sbin/nginx -s stop 
#检查配置文件
./sbin/nginx -t
#动态加载配置文件
./sbin/nginx -s reload
