CentOS 5.5安装Pure-ftpd(无MySQL)

最近想更换一个FTP软件，看到Pure-FTPd不错，对客户端编码支持比较好，尤其是现在我同事大多使用WINDOWS，如果使用VSFTPD，上传上去的文档之类的全部是乱码，而且Pure-Ftpd还可以很方便的打开TLS认证，于是乎先卸载了原本安装的VSFTPD软件，先yum search pure，发现有Pure-FTPD，嘿嘿，直接YUM安装即可。

安装pure-ftpd

yum install pure-ftpd

配置

安装完成之后，就可以进行配置了。下面是我的配置文件，提供给大家看看。

vi /etc/pure-ftpd/pure-ftpd.conf

############################################################ # # # Configuration file for pure-ftpd wrappers # # # ###### # If you want to run Pure-FTPd with this configuration # instead of command-line options, please run the # following command : # # /usr/sbin/pure-config.pl /etc/pure-ftpd/pure-ftpd.conf # # Please don't forget to have a look at documentation at # http://www.pureftpd.org/documentation.shtml for a complete list of # options. # Cage in every user in his home directory 将所有用户锁定于其home目录 ChrootEveryone yes # If the previous option is set to "no", members of the following group # won't be caged. Others will be. If you don't want chroot()ing anyone, # just comment out ChrootEveryone and TrustedGID.设置一个信任的组ID，这样就可以不被锁定于home目录了。 # TrustedGID 100 # Turn on compatibility hacks for broken clients 可以兼容IE浏览器 BrokenClientsCompatibility no # Maximum number of simultaneous users 服务器可以同时登录的最大客户端数目 MaxClientsNumber 50 # Fork in background 是否以守护进程运行 Daemonize yes # Maximum number of sim clients with the same IP address同一IP最大连接数，默认是8 MaxClientsPerIP 4 # If you want to log all client commands, set this to "yes". # This directive can be duplicated to also log server responses.记录所有的客户端命令到日志里面。 VerboseLog no # List dot-files even when the client doesn't send "-a". 显示隐藏文件。 DisplayDotFiles yes # Don't allow authenticated users - have a public anonymous FTP only. 禁止匿名登录 AnonymousOnly no # Disallow anonymous connections.

For instance, if you use MySQLConfigFile, then UnixAuthentication, # the SQL server will be asked. If the SQL authentication fails because the # user wasn't found, another try # will be done with /etc/passwd and # /etc/shadow. If the SQL authentication fails because the password was wrong, # the authentication chain stops here. Authentication methods are chained in # the order they are given. # 'ls' recursion limits. The first argument is the maximum number of # files to be displayed. The second one is the max subdirectories depth LimitRecursion 2000 8 #Are anonymous users allowed to create new directories ?

Umask 133:022 # Minimum UID for an authenticated user to log in. 登录用户的UID如果低于500，是无法登录的。 MinUID 500 # Do not use the /etc/ftpusers file to disable accounts.

This option is incompatible with virtual quotas. # NoTruncate yes # This option can accept three values : # 0 : disable SSL/TLS encryption layer (default). 关闭SSL/TLS加密层，也就是只支持普通的明文连接。 # 1 : accept both traditional and encrypted sessions. 支持明文连接和加密连接。 # 2 : refuse connections that don't use SSL/TLS security mechanisms, # including anonymous sessions.只允许SSL/TLS加密连接。 # Do _not_ uncomment this blindly. Be sure that : # 1) Your server has been compiled with SSL/TLS support (--with-tls), # 2) A valid certificate is in place, # 3) Only compatible clients will log in. TLS 2 # Listen only to IPv4 addresses in standalone mode (ie. disable IPv6) # By default, both IPv4 and IPv6 are enabled. 只监听IPV4地址。 IPV4Only yes # Listen only to IPv6 addresses in standalone mode (ie. disable IPv4) # By default, both IPv4 and IPv6 are enabled. IPV6Only no # UTF-8 support for file names (RFC 2640) # Define charset of the server filesystem and optionnally the default charset # for remote clients if they don't use UTF-8. # Works only if pure-ftpd has been compiled with --with-rfc2640 # 客户端编码 #FileSystemCharset utf-8 ClientCharset gbk

编辑完成后，就可以启动服务了。

chkconfig --levels 235 pure-ftpd on service pure-ftpd start

防火墙规则

接着就可以在iptables里面增加相应的规则，比如运行21端口和PASSIVE端口范围。

iptables -A INPUT -p tcp -m state --state NEW --dport 21 -j ACCEPT iptables -A INPUT -p tcp -m multiport --dports 45000:50000 -j ACCEPT

如果在内网，还需要在网关上添加端口映射。

iptables -t nat -A PREROUTING -d 202.123.212.113 -p tcp -m tcp --dport 2020 -j DNAT --to-destination 192.168.10.3:2020 iptables -t nat -A PREROUTING -d 202.123.212.113 -p tcp -m multiport --dports 43000:45000 -j DNAT --to-destination 192.168.10.3
