最近配置一个gridftp 用于测试其传输ftp性能, 在这里简单记录,备忘;使用本教程可以简单起一个gridftp用于测试服务;

预配置环境:

测试系统:centos 7 1806 

配置yum仓库: 

安装gridftp:

参考文档:

 (管理员手册)

 

yum install osg-gridftp

也可以直接从epel中直接安装:

yum install globus-gridftp-server

启动gridftp匿名服务器:(带有认证的没有配置成功,也不想试了)

globus-gridftp-server -control-interface 0.0.0.0  -aa -p 5000  -anonymous-user 1000  # root 用户使用 1000 表示本地任意一个非root用户
globus-gridftp-server -control-interface 0.0.0.0  -aa -p 5000  # 非 root 用户使用
globus-gridftp-server -control-interface 0.0.0.0  -aa  -p 8080 -anonymous-user 1040 -home-dir /tmp/ -auth-level 0 -allow-root

更多选项可以使用 --help 查看;

安装  globus-url-copy 命令:

yum install globus-gass-copy-progs

生成测试文件:

dd if=/dev/zero of=size80m bs=8k count=10240

输出测试日志:

tail -f /var/log/gridftp-auth.log

运行匿名用户测试:

root@localhost ~# globus-url-copy -v file:///root/size80m ftp://127.0.0.1:5000/tmp/size80m
source: file:///root/
dest:   ftp://127.0.0.1:5000/tmp/
  size80m

测试成功:

[21230] thu sep 19 12:29:09 2019 :: new connection from: localhost:40224
[21230] thu sep 19 12:29:09 2019 :: user anonymous successfully authorized.
[21230] thu sep 19 12:29:09 2019 :: starting to transfer "/tmp/size80m".
[21230] thu sep 19 12:29:12 2019 :: finished transferring "/tmp/size80m".
[21230] thu sep 19 12:29:12 2019 :: closed connection from localhost:40224
[20327] thu sep 19 12:29:12 2019 :: child process 21230 ended with rc = 0

安装gridftp 客户端:

[root@xuyaowen ~]# yum search gridftp | grep -i client
last metadata expiration check: 2:28:09 ago on thu 19 sep 2019 11:44:29 am cst.
edg-gridftp-client.x86_64 : command line clients to gridftp libraries
uberftp.x86_64 : gridftp-enabled ftp client  (听说是最好用的工具, 但是我一运行就崩溃,最终还是使用 globus-url-copy 命令进行测试)
globus-ftp-client.x86_64 : grid community toolkit - gridftp client library
globus-ftp-client-devel.x86_64 : grid community toolkit - gridftp client library

测试吞吐:

 # test network throughput
 globus-url-copy -vb -p 4 ftp://10.134.150.5:5000/dev/zero file:///dev/null

顺序读:

#  tmp globus-url-copy -vb -p 4 ftp://10.134.150.5:5000/dev/zero file:///dev/null

顺序写:

#  tmp globus-url-copy -vb -p 4 file:///dev/zero ftp://10.134.150.5:5000/dev/null

使用udt:

globus-gridftp-server -control-interface 0.0.0.0  -aa  -p 5000 -anonymous-user 1040 -home-dir /tmp/ -auth-level 0 -allow-root -allow-udt
globus-url-copy -vb -p 4 -udt ftp://10.134.150.5:5000/dev/zero file:///dev/null

           order specified from bottom to top (e.g. -dcstack tcp,gsi). if the gsi driver is not included in the stack and data channel authentication is enabled, it will be inserted
           above the transport driver in the stack.

       -fsstack stack, -file-system-stack stack
           set the xio driver stack for the disk on both the source and the destination. both must be gridftp servers. the stack should contain all file system drivers to use, in the

       -af filename, -alias-file filename
           file with mapping of logical host aliases to lists of physical hosts. when used with multiple concurrent connections, each connection uses the next host in the list. each
           line should either be an alias, noted with the @ symbol, or a hostname[:port]. currently, only the aliases @source and @destination are valid, and they are used for every
           source or destination url.

       -sync
           only transfer files where the destination does not exist or differs from the source. -sync-level controls how to determine if files differ.

       -sync-level number
           criteria for determining if files differ when performing a sync transfer. the default sync level is 2. the available levels are:

           ·   level 0 will only transfer if the destination does not exist.

           ·   level 1 will transfer if the size of the destination does not match the size of the source.

           ·   level 2 will transfer if the time stamp of the destination is older than the time stamp of the source.

           ·   level 3 will perform a checksum of the source and destination and transfer if the checksums do not match. the default algorithm used for this checksum is md5, but
               other algorithms can be specified with the -algo parameter.

       -checksum-alg checksum-algorithm
           set the algorithm type to use for all checksum operations during the transfer.

       -verify-checksum
           perform a checksum on the source and destination after each file transfer and compare the two. if they do not match, fail the transfer. the default algorithm used for this
           checksum is md5, but other algorithms can be specified with the -checksum-alg parameter.

       the globus-gridftp-server program is a ftp server with support for gridftp protocol extensions, including strong authentication, parallel data transfers, and parallel data
       layouts.

options
       the list below contains the command-line options for the server, and also the name of the configuration file entry that implements that option. note that any boolean option
       can be negated on the command line by preceding the specified option with -no- or -n. example: -no-cas or -nf.

   informational options
       -h,-help
           show usage information and exit.

           this option can also be set in the configuration file as help. the default value of this option is false.

       -hh,-longhelp
           show more usage information and exit.

           this option can also be set in the configuration file as longhelp. the default value of this option is false.

       -v,-version
           show version information for the server and exit.

           this option can also be set in the configuration file as version. the default value of this option is false.

       -v,-versions
           show version information for all loaded globus libraries and exit.

           this option can also be set in the configuration file as versions. the default value of this option is false.

   modes of operation
       -i,-inetd
           run under an inetd service.

           this option can also be set in the configuration file as inetd. the default value of this option is false.

       -s,-daemon
           run as a daemon. all connections will fork off a new process and setuid if allowed.

           this option can also be set in the configuration file as daemon. the default value of this option is true.

       -s,-detach
           run as a background daemon detached from any controlling terminals.

           this option can also be set in the configuration file as detach. the default value of this option is false.

       -ssh
           run over a connected ssh session.

           this option can also be set in the configuration file as ssh. the default value of this option is false.

       -exec string
           for statically compiled or non-globus_location standard binary locations, specify the full path of the server binary here. only needed when run in daemon mode.

           this option can also be set in the configuration file as exec.
