linux 安装nginx ftp

1.安装nginx

 

nginx-1.13.9

下载地址:http://nginx.org/download/nginx-1.13.9.tar.gz

[root@localhost ~]# wget http://nginx.org/download/nginx-1.13.9.tar.gz

解压

[root@localhost ~]# tar -zxvf nginx-1.13.9.tar.gz 

进入目录

[root@localhost ~]# cd  nginx-1.13.9

编译

[root@localhost nginx-1.13.9]# ./configure

注意:这时候报错了

checking for OS
 + Linux 3.10.0-693.el7.x86_64 x86_64
checking for C compiler ... not found

./configure: error: C compiler cc is not found

这时候我们就要百度一下了,百度得知我们少一个gcc编译器 可以这么去安装 yum -y install gcc-c++

[root@localhost nginx-1.13.9]# yum -y install gcc-c++

一大堆的提示,也看不懂,最后就安装好了

再次编译

./configure

提示错误,我们需要一些安装库

[root@localhost nginx-1.13.9]# yum install -y pcre pcre-devel

[root@localhost nginx-1.13.9]# yum install -y zlib zlib-devel

[root@localhost nginx-1.13.9]# yum install -y openssl openssl-devel

 

再次编译

./configure

 

 

安装

[root@localhost nginx-1.13.9]# make && make install

 

 

设置开机自启动

[root@localhost nginx-1.13.9]# vi /etc/rc.local

添加一句

/usr/local/nginx/sbin/nginx

[root@localhost nginx-1.13.9]# chmod 755  /etc/rc.local 

进入启目录

[root@localhost nginx-1.13.9]# cd  /usr/local/nginx/sbin/

[root@localhost sbin]# ./nginx 

启动

运行192.168.88.12,看看效果

 

看到这个图表示成功了.

 修改配置支持ftp

user  root;

server {
listen 80;
server_name 192.168.88.12;

#charset koi8-r;

#access_log logs/host.access.log main;

location ~* \.(mp4)$ {
expires 30d;
valid_referers 127.0.0.1;
if ($invalid_referer) {
return 404;
}
root /ftpvideo/video;
}

location / {
root html;
index index.html index.htm;
}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

 

 

安装  vsftpd

#查询是否安装
[root@localhost conf]# vsftpd -version

直接安装

[root@localhost conf]# yum install -y vsftpd

安装完成后创建一个目录,作为上传目录,最好和nginx 的目录一致这里我们配置为nginx里面配置的那个/ftpvideo/video

 

[root@localhost /]# mkdir  -p  /ftpvideo/video

添加一个系统账户

[root@localhost /]# useradd -d /ftpvideo/video -s /bin/bash ftpadmin

-d指定 用户的家目录,以后用做ftp上传的目录.-s指定是否可以登录  ,最后是用户名称.

设置密码

可以使用passwd命令设置,但是密码强度要求较高,我是自己的虚拟机,所以简单点.

[root@localhost /]# echo 123456|passwd --stdin ftpadmin

 

可能要修改防火墙,这里我是关闭了防火墙,所以不用设置,具体的我也不知道怎么设置,百度吧.

为了安全,我们要设置用户只能访问自己的家目录,也就是我们配置的那个/ftpvideo/video

修改/etc/vsftpd.conf

[root@localhost vsftpd]# cd  /etc/vsftpd/

[root@localhost vsftpd]# vi vsftpd.conf

把下面这几个改为NO,关闭匿名访问

anonymous_enable=NO

local_enable=NO

write_enable=NO

取消chroot_local_user=YES的注释

ascii_upload_enable=YES
ascii_download_enable=YES

 

在最后添加

allow_writeable_chroot=YES

 

设置开机启动

[root@localhost vsftpd]# systemctl enable vsftpd.service

启动ftp

[root@localhost vsftpd]# systemctl start  vsftpd.service

设置不能登录linux

[root@localhost vsftpd]# usermod -s /usr/sbin/nologin ftpadmin

链接测试 

可以登录,但是无法上传文件,最后分析是权限问题

chmod -R 777 /ftpvideo
