【高性能服务器】- Nginx

安装依赖包

sudo apt-get install libpcre3 libpcre3-dev  zlib1g-dev  openssl

编译

cd /usr/local/src
wget http://nginx.org/download/nginx-1.4.2.tar.gz
tar -zxvf nginx-1.4.2.tar.gz
cd nginx-1.4.2
 

# 安装tcp反向代理模块 
./configure  --prefix=/usr/local/nginx --with-stream
make
make install

配置stream

注意这个模块与http是同级的,不要配置到http模块里面了,TCP长连接只需要下面精简配置就行,多了反而nginx与客户端无法保持链接

stream {
    upstream push-connector {
        hash $remote_addr consistent;
        server 172.16.177.107:6789 weight=1 max_fails=3 fail_timeout=30s;
        server 172.16.176.23:6789 weight=1 max_fails=3 fail_timeout=30s;
        server 172.16.176.25:6789 weight=1 max_fails=3 fail_timeout=30s;
    }
    server {
        listen 9945;
        proxy_pass push-connector;
    }
}


测试

sudo /usr/local/nginx    #启动sudo /usr/local/nginx -c /usr/local/nginx.conf
sudo /usr/local/nginx -t #检测配置文件是否正确 
sudo /usr/local/nginx -s stop #停止 
sudo /usr/local/nginx -s reload #重载配置文件
