  • 编译安装nginx

#安装依赖环境

yum install -y gcc-c++ gcc pcre pcre-devel  zlib zlib-devel openssl openssl-devel perl-devel perl-ExtUtils-Embed 


#下载并解压包

wget http://nginx.org/download/nginx-1.13.9.tar.gz

tar axf nginx-1.13.9.tar.gz


编译安装

  • nginx负载均衡

再安装两个nginx,一个用于静态页面访问,一个用于负载均衡

官方文档:http://nginx.org/en/docs/stream/ngx_stream_proxy_module.html

安装

静态网站同上,注意修改监听端口


负载均衡

cd nginx-1.13.9

 ./configure --prefix=/usr/local/nginx_proxy \

 --with-http_ssl_module \

 --with-http_perl_module \

 --with-pcre \

 --with-http_stub_status_module \
