阿里云 CentOS7.2 配置FTP+Node.js环境

本人小白，写下这篇博客意在记录踩过的坑，大神请绕道~

准备工作

安装自己喜欢的连接软件（一般是putty或者xshell），本人选择的是xshell，软件如图 ：

通过软件中的ssh连接连接上已经购买的服务器，具体账号密码可在阿里云的控制台设置 。

在控制台选择主机系统为CentOS7.2，连接上了之后首先先将服务器更新至最新版本。

 yum -y update 

接着安装编译源代码的开发工具 。

 yum -y groupinstall "Development Tools" 

FTP的安装

1.安装vsftpd的服务器和客户端

 sudo yum install ftp vsftpd

2.安装一个加密工具

 sudo yum install libdb-utils.x86_64

【大坑提醒】

不知道是我的个人情况还是通病，在使用VIM时会报

 -bash: vim: command not found.

但是VI命令使用正常，遇到这种情况一般是VIM相关组件没有安装完成，可以通过命令查看

 # rpm -qa |grep vim

VIM命令可用时返回为

 vim-minimal-7.0.-.el5
 vim-common-7.0.-7.2.el5
 vim-enhanced-7.0.-7.2.el5

以上三条缺一不可，如果有空缺可用代码重新安装

 yum -y install vim*

VIM的使用

进入编辑模式 a

进入命令行模式 esc

直接退出 :q

保存退出 :wq

vsftpd的配置

创建vsftp的登录用户和主目录

 sudo useradd -d /home/myftp -s /sbin/nologin myftp（myftp是ftp的登录用户，替换成你自己的用户）

进入修改相对应用户的密码

 passwd myftp

创建出vsftpd虚拟用户

 sudo touch /etc/vsftpd/vftpuser.txt

文件里为

 用户1
 用户1密码
 用户2
 用户2密码
 ......

 sudo db_load -T -t hash -f /etc/vsftpd/vftpuser.txt /etc/vsftpd/vftpuser.db 

添加vsftpd的虚拟用户的验证

 sudo vim /etc/pam.d/vsftpd 

替换其中account和auth

 session    optional     pam_keyinit.so    force revoke
 #auth       required    pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed
 #auth       required    pam_shells.so
 #auth       include     password-auth
 #account    include     password-auth
 auth required pam_userdb.so db=/etc/vsftpd/vftpuser
 account required pam_userdb.so db=/etc/vsftpd/vftpuser
 session    required     pam_loginuid.so
 session    include      password-auth

修改vsftpd的配置文件

 sudo vim /etc/vsftpd/vsftpd.conf 

以下为删除了注释的配置好的版本

 # 是否运行匿名登录（NO）
 anonymous_enable=NO
 # 是否允许本地用户登录
 local_enable=YES
 # 允许ftp的任何写方式
 write_enable=YES
 # 文件创建只有的权限是755=（-）
 local_umask=
 # 是否允许匿名用户上传文件
 #anon_upload_enable=YES
 # 是否允许匿名用户创建文件或者删除文件
 #anon_mkdir_write_enable=YES
 # 用户进入目录信息提示
 dirmessage_enable=YES
 # 是否允许vsftp的日志
 xferlog_enable=YES
 # Make sure PORT transfer connections originate from port  (ftp-data).
 connect_from_port_20=YES
 #
 #chown_uploads=YES
 #chown_username=whoever
 # 日志文件的路径
 xferlog_file=/var/log/xferlog
 # 日志文件的格式
 xferlog_std_format=YES
 #
 #idle_session_timeout=
 #
 #data_connection_timeout=
 #
 # It is recommended that you define on your system a unique user which the
 # ftp server can use as a totally isolated and unprivileged user.
 #nopriv_user=ftpsecure
 #
 # Enable this and the server will recognise asynchronous ABOR requests. Not
 # recommended for security (the code is non-trivial). Not enabling it,
 # however, may confuse older FTP clients.
 #async_abor_enable=YES
 #
 # By default the server will pretend to allow ASCII mode but in fact ignore
 # the request. Turn on the below options to have the server actually do ASCII
 # mangling on files when in ASCII mode.
 # Beware that on some FTP servers, ASCII support allows a denial of service
 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
 # predicted this attack and has always been safe, reporting the size of the
 # raw file.
 # ASCII mangling is a horrible feature of the protocol.
 #ascii_upload_enable=YES
 #ascii_download_enable=YES
 #
 # You may fully customise the login banner string:
 #ftpd_banner=Welcome to blah FTP service.
 #
 # You may specify a file of disallowed anonymous e-mail addresses. Apparently
 # useful for combatting certain DoS attacks.
 #deny_email_enable=YES
 # (default follows)
 #banned_email_file=/etc/vsftpd/banned_emails
 #
 # You may specify an explicit list of local users to chroot() to their home
 # directory. If chroot_local_user is YES, then this list becomes a list of
 # users to NOT chroot().
 # (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
 # the user does not have write access to the top level directory within the
 # chroot)
 chroot_local_user=YES
 chroot_list_enable=YES
 # (default follows)
 #chroot_list_file=/etc/vsftpd/chroot_list
 #
 # You may activate the "-R" option to the builtin ls. This is disabled by
 # default to avoid remote users being able to cause excessive I/O on large
 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
 # the presence of the "-R" option, so there is a strong case for enabling it.
 #ls_recurse_enable=YES
 #
 # When "listen" directive is enabled, vsftpd runs in standalone mode and
 # listens on IPv4 sockets. This directive cannot be used in conjunction
 # with the listen_ipv6 directive.
 # 只监听ipv4的地址
 listen=YES
 #
 # This directive enables listening on IPv6 sockets. By default, listening
 # on the IPv6 "any" address (::) will accept connections from both IPv6
 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
 # sockets. If you want that (perhaps because you want to listen on specific
 # addresses) then you must run two copies of vsftpd with two configuration
 # files.
 # Make sure, that one of the listen options is commented !!
 #listen_ipv6=YES

 pam_service_name=vsftpd
 userlist_enable=YES
 tcp_wrappers=YES
 # 下面是自己添加的
 anon_root=/home/pageftp/open
 virtual_use_local_privs=YES
 guest_enable=YES
 guest_username=pageftp
 # 虚拟用户的配置文件（可以对每一个虚拟用户进行单独的权限配置）
 user_config_dir=/etc/vsftpd/vconf/
 chroot_local_user=YES
 allow_writeable_chroot=YES

配置虚拟用户的权限

 sudo mkdir /etc/vsftpd/vconf/
 touch 用户1 用户2 ……
 vim 用户1

配置结果如下

 cmds_allowed=ABOR,ACCT,APPE,CWD,CDUP,DELE,HELP,LIST,MODE,MDTM,MKD,NOOP,NLST,PASS,PASV,PORT,PWD,QUIT,REIN,RETR,RMD,RNFR,RNTO,SITE,SIZE
 ,STOR,STAT,STOU,STRU,SYST,TYPE,USER
 write_enable=yes
 download_enable=yes
 anon_upload_enable=yes
 anon_mkdir_write_enable=yes
 anon_other_write_enable=yes
 anon_world_readable_only=no

最后启动vsftpd服务

 sudo systemctl enable vsftpd
 sudo service vsftpd start

使用刚设置的用户名和密码通过FTP连接观察，本人选用软件FlashFXP。

Node.js环境安装

使用最新源码安装，资源从Node.js网站获取，地址为http://nodejs.org/download

 wget http://nodejs.org/dist/v6.5.0/node-v6.5.0.tar.gz (版本号可根据实际需求自行替换)

解压源文件并进入相应文件夹

 tar zxf node-v6.5.0.tar.gz
 cd node-v6.5.0

执行编译预处理

 ./configure 

编译源代码

 make

放置至系统路径

 make install

成功安装
