我对rsync感到疯狂，这给了我一个＆＃34;连接拒绝＆＃34;错误。这是我的问题： 我有两台服务器，用于存储数据，安装了rsync，因为我需要两台服务器保持同步。通过这种方式，在一台服务器上修改将导致相同的修改，反之亦然。第一个节点（sn1）工作，而第二个节点（sn2）不工作。详情。 - sn1的IP地址为192.168.13.131 - sn2的IP地址为192.168.13.132
如果我从sn1或sn2中提供rsync rsync://192.168.13.131，它可以正常工作;如果我从sn1或sn2给出rsync rsync://182.168.13.132，我会收到此错误：
rsync: failed to connect to 192.168.13.132 (192.168.13.132): Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(125) [Receiver=3.1.2]
这里有关于sn2的一些信息。 的 /etc/rsyncd.conf

# defaults file for rsync daemon mode
#
# This file is only used for init.d based systems!
# If this system uses systemd, you can specify options etc. for rsync
# in daemon mode by copying /lib/systemd/system/rsync.service to
# /etc/systemd/system/rsync.service and modifying the copy; add required
# options to the ExecStart line.
# start rsync in daemon mode from init.d script?
# only allowed values are "true", "false", and "inetd"
# Use "inetd" if you want to start the rsyncd from inetd,
# all this does is prevent the init.d script from printing a message
# about not starting rsyncd (you still need to modify inetd's config yourself).
RSYNC_ENABLE=true
# which file should be used as the configuration file for rsync.
# This file is used instead of the default /etc/rsyncd.conf
# Warning: This option has no effect if the daemon is accessed
# using a remote shell. When using a different file for
# rsync you might want to symlink /etc/rsyncd.conf to
# that file.
# RSYNC_CONFIG_FILE=
# what extra options to give rsync --daemon?
# that excludes the --daemon; that's always done in the init.d script
# Possibilities are:
# --address=123.45.67.89 (bind to a specific IP address)
# --port=8730 (bind to specified port; default 873)
RSYNC_OPTS=''
# run rsyncd at a nice level?
# the rsync daemon can impact performance due to much I/O and CPU usage,
# so you may want to run it at a nicer priority than the default priority.
# Allowed values are 0 - 19 inclusive; 10 is a reasonable value.
RSYNC_NICE=''
# run rsyncd with ionice?
# "ionice" does for IO load what "nice" does for CPU load.
# As rsync is often used for backups which aren't all that time-critical,
# reducing the rsync IO priority will benefit the rest of the system.
# See the manpage for ionice for allowed options.
# -c3 is recommended, this will run rsync IO at "idle" priority. Uncomment
# the next line to activate this.
# RSYNC_IONICE='-c3'
# Don't forget to create an appropriate config file,
# else the daemon will not start.

这是我在两个节点之间看到的主要区别。
在sn1上输出命令sudo systemctl status rsync：

在sn1上输出命令sudo netstat -lptu | grep rsync：

我在虚拟机上的每个服务器节点中运行ubuntu 18.04。 你能帮我弄清楚发生了什么吗？不幸的是我必须使用rsync，因为我正在使用OpenStack Swift，因此不允许进行任何更改：）
答案 0 :(得分：1)
好的，我已经完成了。简单来说，只需获得超级用户权限，然后启用并启动rsync进程：
sudo su
输入您的密码，然后输入数字
systemctl enable rsync
systemctl start rsync
如果您没有基于systemctl的终端，请改为使用“service”。
service rsync restart
您可以通过访问/var/log/rsyncd.log来检查rsync现在是否正常工作。 bind（）错误现在消失了。

在默认配置下，我总是执行rsync -rtP /home/me/source/ x.x.x.x:/home/someoneelse/source（其中x.x.x.x是实际的IP地址）。我不知道何时或是否需要将rsync://指定为协议。就我而言，在启用sshd之前，我一直遇到您的错误。我还安装了rsync-daemon，但我实际上不知道是否需要这样做。这是完整的解决方案（我只在远程计算机上执行此操作-我相信本地计算机（只有我自己才能在其上成功运行上述命令，并且仅具有openssh和rsync程序包）：
sudo dnf -y install rsync-daemon openssh
sudo systemctl enable rsyncd
sudo systemctl start rsyncd
sudo systemctl enable sshd
sudo systemctl start sshd
需要明确的是，我有Fedora 27，sudo systemctl status firewalld说防火墙正在运行，并且我不必手动创建我知道的防火墙规则（bash中没有防火墙或iptables的实例）历史）。在成功运行的命令（此答案的顶部）中，我使用了一些选项，但不是必需的：r：递归，t：将时间戳复制到目标文件，P ：显示进度。正斜杠（/）仅位于源路径的末尾，因此rsync不会在目标位置创建名为/ home / someoneelse / source / source的目录。
