本文介绍了在CentOS 6.6系统上部署nginx-1.8.0的过程，包括安装依赖、配置文件修改以及遇到的404错误和连接拒绝问题。在部署完成后，通过访问80端口验证成功，但在尝试部署多个站点时遇到启动异常，error.log显示"(111: Connection refused) while connecting to upstream"错误。进一步的排查措施包括检查端口使用和nginx进程，但问题仍未解决。

一、说明
系统：centos 6.6
nginx版本：nginx-1.8.0
二、nginx安装
安装步骤
（1）安装依赖包：gcc，pcre，zlib，openssl
（2）安装nginx-1.8.0
1、安装依赖包：

cd /usr/local
yum install -y gcc gcc-c++
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel

2、安装nginx-1.8.0

wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar -zxvf nginx-1.8.0.tar.gz 
cd nginx-1.8.0
./configure --user=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_gzip_static_module --with-http_realip_module --with-http_sub_module --with-http_ssl_module
make install
ls ../
cd ../nginx
cd sbin/
./nginx
ps -ef | grep nginx
root      1821     1  0 00:44 ?        00:00:00 nginx: master process ./nginx
nobody    1822  1821  0 00:44 ?        00:00:00 nginx: worker process
root      1824  1753  0 00:44 pts/0    00:00:00 grep nginx

在本机浏览器访问部署nginx的80端口http://...:80，显示图下页面即为部署成功。

至此nginx安装完毕。
3、修改配置文件
需要同时部署2个，

cd /usr/local/nginx/conf
cp nginx nginx.bak
vi nginx

启动异常，报错如下图，检查error.log报错
nginx启动异常
