# [安装Nginx四层负载均衡][Nginx] #

**Nginx1.9开始支持tcp层的转发，通过stream实现的，而socket也是基于tcp通信。**

**stream模块默认不安装的，需要手动添加参数：–with-stream，官方下载地址：download，根据自己系统版本选择nginx1.9或以上版本**

**./configure --add-module=../yaoweibin-nginx\_tcp\_proxy\_module-121c026              **

1、Nginx安装：参考https://www.cnblogs.com/toov5/p/9902692.html   安装支持TCP协议的四层负载均衡Nginx

下载   wget [http://nginx.org/download/nginx-1.9.10.tar.gz][http_nginx.org_download_nginx-1.9.10.tar.gz]

解压  tar -xzvf nginx-1.9.0.tar.gz

补丁命令安装   yum -y install patch

打补丁  patch -p1 <  ../yaoweibin-nginx\_tcp\_proxy\_module-121c026/tcp.patch

编译Nginx

./configure --add-module=../yaoweibin-nginx\_tcp\_proxy\_module-121c026

make && make install

    make: *** [build] 错误 2

原因：不是最新补丁

解决：

1.  wget https://github.com/yaoweibin/nginx\_tcp\_proxy\_module/archive/master.zip

2.patch -p1 </home/nginx/patch/nginx\_tcp\_proxy\_module-master/tcp.patch    (绝对目录)

3.  ./configure --add-module=/home/nginx/patch/nginx\_tcp\_proxy\_module   （nginx目录里面操作）

解决完毕：

继续  ./configure --add-module=../yaoweibin-nginx\_tcp\_proxy\_module-121c026

然后  make && make install
