环境

linux服务器
nginx软件

nginx安装

1、安装编译工具及库文件

‍[yunweijia@localhost jier]$ sudo yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

2、**安装 PCRE

[yunweijia@localhost jier]$ cd /usr/local/src/
[yunweijia@localhost src]$ sudo wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz  下载
[yunweijia@localhost src]$ sudo tar xf pcre-8.35.tar.gz  # 解压
[yunweijia@localhost src]$ cd pcre-8.35/
[yunweijia@localhost pcre-8.35]$ sudo ./configure  # 编译
[yunweijia@localhost pcre-8.35]$ sudo make && make instal  # 安装
[yunweijia@localhost pcre-8.35]$ pcre-config --version  # 版本查看
8.32
[yunweijia@localhost pcre-8.35]$

3、安装nginx

[yunweijia@localhost jier]$ pwd
/home/yunweijia/jier
[yunweijia@localhost jier]$ ls
nginx-1.14.2.tar.gz
[yunweijia@localhost jier]$ tar xf nginx-1.14.2.tar.gz 
[yunweijia@localhost jier]$ cd nginx-1.14.2/
[yunweijia@localhost nginx-1.14.2]$ sudo ./configure --prefix=/home/yunweijia/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[yunweijia@localhost nginx-1.14.2]$ sudo make && make install

4、配置调整

[yunweijia@localhost nginx-1.14.2]$ cd /home/yunweijia/nginx/
[yunweijia@localhost nginx]$ ls
conf  html  logs  sbin
[yunweijia@localhost nginx]$ vim conf/nginx.conf
# 以下内容是配置文件的第二行进行配置
user root;
# 以下配置是唉server中进行新增
        location ~* (.*.txt) {  # 代理后缀为txt的
            add_header  Content-Type    "application/octet-stream";
            if ( $args ~ ^filename=(.*) ) {
                add_header  Content-Disposition "attachment; filename=$1";
            }
            yunweijia /home/yunweijia/txt/;  # 在这个目录下
        }

5、启动nginx

[yunweijia@localhost nginx]$ sudo ./sbin/nginx -t  # 检查配置
nginx: the configuration file /home/yunweijia/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /home/yunweijia/nginx/conf/nginx.conf test is successful
[yunweijia@localhost nginx]$ sudo ./sbin/nginx  # 启动

6、验证

在"/home/yunweijia/txt/"中新建文件，测试下载。

下载url为：http://ip地址:端口号/文件名

[yunweijia@localhost nginx]$ mkdir /home/yunweijia/txt/
[yunweijia@localhost nginx]$ cd /home/yunweijia/txt/
[yunweijia@localhost txt]$ ls
[yunweijia@localhost txt]$ echo ceshi > 1.txt
[yunweijia@localhost txt]$ cat 1.txt 
ceshi
[yunweijia@localhost txt]$

浏览器输入地址为：http://192.168.112.130/1.txt

文件下载成功。
