直接采用压缩包下载安装
第一步,安装依赖

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

第二步,找个位置下载
例如我 的linux 路径 /home/home1/opt/nginx

wget http://nginx.org/download/nginx-1.13.7.tar.gz

然后解压

tar -xvf nginx-1.13.7.tar.gz

进入nginx目录

cd  /home/home1/opt/nginx

执行命令

# 编译
make  
# 安装
make install

然后执行如下命令启动

 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

配置nginx.conf

贴出我自己的一个配置文件

}

配置好后,重启nginx

#重启
/usr/local/nginx/sbin/nginx -s reload

#停止
/usr/local/nginx/sbin/nginx -s stop

我配置文件中的端口为8088,所以我的访问如下

这样,nginx就配置好了
