首先去http://nginx.org/en/download.html下载nginx-1.8.0，这里我下载到opt目录
后面我要设置nginx使用nginx用户和nginx用户组，所以执行下面命令
groupadd nginx
useradd -g nginx -s /sbin/nologin -M nginx
接下来安装编译环境
yum -y install pcre-devel
yum -y install gcc gcc-c++ ncurses-devel perl
yum -y install zlib zlib-devel
yum -y install openssl openssl-devel
然后解压文件准备编译
cd /opt
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
开始编译和安装
./configure --user=nginx --group=nginx --prefix=/opt/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module
make
make install
编译完成之后，测试安装效果，出现版本号为安装成功
cd /opt/nginx/sbin
./nginx -v
将以下脚本保存为nginx文件就在/etc/init.d目录下，注意如果你用外部编辑器请确认换行符为LINUX的，编码正确，其中/opt/nginx/请替换成你的安装目录

echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL
然后执行下列命令，把nginx加入系统服务并设置成开机启动。如果你的配置跟我不一样请注意目录，用户名和用户组的替换
chmod 755 /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
chown -R nginx:nginx /opt/nginx
最后启动nginx就可以了，别忘了开放80端口
service nginx start
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
service iptables save
chkconfig iptables on
