rsync 错误 failed: Permission denied (13)

Posted 2022-09-01 catoop

在使用 rsync 同步的时候出现如下错误（示例）：

rsync: opendir "/data/javaprefs/.java/.userPrefs" (in nexus3) failed: Permission denied (13)
rsync: send_files failed to open "/data/tmp/c4c97e7a-sysout-over-slf4j-1.0.2.jar" (in nexus3): Permission denied (13)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1651) [generator=3.1.2]

以以上错误为例，解决方法可以有2种（在 rsync 服务端上操作）：

方法1：

设置服务器端出现权限错误的目录权限为 7555

chmod 755 data/javaprefs/.java/.userPrefs

方法2：

设置服务的配置文件 /etc/rsync uid 和 gid 为 0，配置文件如下所示：

# /etc/rsyncd: configuration file for rsync daemon mode

# See rsyncd.conf man page for more options.

# configuration example:

# uid = nobody
uid = 0
# gid = nobody
gid = 0
# use chroot = yes
# max connections = 4
# pid file = /var/run/rsyncd.pid
# exclude = lost+found/
# transfer logging = yes
# timeout = 900
# ignore nonreadable = yes
# dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2

# [ftp]
#        path = /home/ftp
#        comment = ftp export area
[nexus3]
path = /opt/soft/nexus3
