在linux下使用Apache搭建文件服务器
一.关于文件服务器
在一个项目中，如果想把公共软件或者资料共享给项目组成员，可以搭建一个简易的文件服务器来实现，只要是在局域网内的成员都可以通过浏览器或者wget命令来下载和访问资料。可以达到信息共享，软件版本一致的效果。本文讲述在linux环境下使用Apache服务搭建文件服务器。
二.使用Apache搭建文件服务器
1.Apache服务在linux环境下的程序叫做httpd，所以首先安装httpd服务，如果配置好了yum源的话，直接使用yum命令安装,如果没有配置好yum源的话，可以参考博客“linux 配置本地yum源，配置国内yum源，配置epel源”进行配置，网址为：https://www.cnblogs.com/renshengdezheli/p/13949693.html
[root@node5 ~]# yum -y install httpd
2.启动httpd服务
#启动httpd服务
[root@node5 ~]# systemctl start httpd
#查看httpd服务状态
[root@node5 ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server

#查看Apache版本
[root@node5 ~]# httpd -version
Server version: Apache/2.4.6 (CentOS)
Server built: Nov 16 2020 16:18:20
3.查看IP地址，访问Apache页面
#可以看到本机IP地址为192.168.110.184
[root@node5 soft]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.110.184 netmask 255.255.255.0 broadcast 192.168.110.255
ether 00:0c:29:11:c4:4a txqueuelen 1000 (Ethernet)
RX packets 24682 bytes 13301526 (12.6 MiB)

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 2402 bytes 221903 (216.7 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 2402 bytes 221903 (216.7 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
在浏览器里访问http://192.168.110.184/，如果出现如下界面说明Apache服务安装成功
4.创建共享目录/opt/soft，把需要共享的文件都放在这个目录
[root@node5 soft]# mkdir /opt/soft
#此命令把系统所有的tar.gz的压缩包都放在共享目录里
[root@node5 soft]# find / -name "*.tar.gz" -exec mv {} /opt/soft \;
[root@node5 soft]# ls /opt/soft/
amhello-1.0.tar.gz elasticsearch-6.2.2.tar.gz FastDFS_v5.08.tar.gz kibana-6.2.2-linux-x86_64.tar.gz nginx-1.19.3.tar.gz ntp-4.2.6p5.tar.gz tomcat-native.tar.gz
apache-tomcat-8.0.51.tar.gz fastdfs_client_java._v1.25.tar.gz findfile.tar.gz libopts-40.0.15.tar.gz nginx-1.8.0.tar.gz rarlinux-3.8.0.tar.gz 饼干.txt
commons-daemon-native.tar.gz fastdfs-nginx-module_v1.16.tar.gz jdk-8u172-linux-x64.tar.gz nginx-1.10.0.tar.gz ngx_cache_purge-2.3.tar.gz today_db.tar.gz
5.因为访问Apache页面默认读取的是/var/www/html/页面，所以把共享目录链接到/var/www/html/下就可以了
[root@node5 ~]# ln -s /opt/soft /var/www/html/file
[root@node5 ~]# ll /var/www/html/file
lrwxrwxrwx 1 root root 9 Dec 17 16:29 /var/www/html/file -> /opt/soft
6.重启Apache服务，查看页面
[root@node5 ~]# systemctl restart httpd
使用浏览器访问http://192.168.110.184/file/，如果出现如下界面，就说明文件服务器搭建好了
7.通过网页我们发现中文是乱码，可以修改配置文件使中文正常显示
#在Apache配置文件的末尾追加一行
[root@node5 ~]# echo "IndexOptions Charset=UTF-8" >> /etc/httpd/conf/httpd.conf
[root@node5 ~]# systemctl restart httpd
再次访问网页http://192.168.110.184/file/，发现页面的中文正常显示了
三.测试文件服务器是否可用
1.在windows上使用浏览器访问http://192.168.110.184/file/，如果页面可以打开，并且点击软件会自动下载，说明通过windows下载文件成功。
2.在局域网内的另外一台linux机器上测试是否可以下载文件
#首先在node8机器上使用root账户测试下载文件
#使用wget命令下载文件
[root@node8 ~]# wget http://192.168.110.184/file/饼干.txt
