什么是rsync
rsync,remote synchronize顾名思意就知道它是一款实现远程同步功能的软件,它在同步文件的同时,可以保持原来文件的权限、时间、软硬链接等附加信息。 rsync是用 “rsync 算法”提供了一个客户机和远程文件服务器的文件同步的快速方法,而且可以通过ssh方式来传输文件,这样其保密性也非常好,另外它还是免费的软件。
rsync 包括如下的一些特性:
能更新整个目录和树和文件系统;
有选择性的保持符号链链、硬链接、文件属于、权限、设备以及时间等;
对于安装来说,无任何特殊权限要求;
对于多个文件来说,内部流水线减少文件等待的延时;
能用rsh、ssh 或直接端口做为传输入端口;
支持匿名rsync 同步文件,是理想的镜像工具;
rsync 是一个快速增量文件传输工具,它可以用于在同一主机备份内部的备分,我们还可以把它作为不同主机网络备份工具之用。本文主要讲述的是如何自架rsync服务器,以实现文件传输、备份和镜像。
1.服务器端
mkdir -p /data/allbackdata/ # uid git 可以改成你所想要的 echo ' ###################################################################################################### # ******进程相关全局配置****** ###################################################################################################### # = 后面的值可根据自己的实际情况更改 # pid file 守护进程pid文件 # port 守护进程监听端口,可更改,由xinetd允许rsyncd时忽略此参数 # address 守护进程监听ip,由xinetd允许rsyncd时忽略此参数 port = 873 #address = 192.168.1.2 #很多时候这个不要 uid=root gid=root #hosts allow = 192.168.1.130 # \\ 允许同步的机器,可以是一个网段 很多时候这个不要 #hosts deny = 0.0.0.0/0 #\\ 拒绝同步的机器,这里是只允许上面指定的机器 很多时候这个不要 use chroot = yes # 这个很多时候不敢要 read only = no max connections = 80 timeout = 300 # read only = false 允许client上传 # wirte only = false 允许 client 下载 max connections = 20 timeout = 300 #欢迎文件路径,可选的 motd file = /etc/rsyncd.motd pid file = /var/run/rsyncd.pid log file = /data/logs/rsync.log lock file = /var/run/rsync.lock secrets file = /etc/pass.crt [data] path = /data/allbackdata/ #是否允许列出模块里的内容 list=yes #忽略错误 #ignore errors #排除目录,多个之间使用空格隔开 exclude = test1/ test2 auth users = ops ' > /etc/rsyncd.conf #Note client 只要密码 不用写上用户哦 Nov 25 2021, #但是这是server端 两个全要 echo 'ops:3636' > /etc/pass.crt chmod 600 /etc/pass.crt #注意 这个一定得是 600 不然权限太大 失败的 Oct 16 cat /var/jenkins_home/lcpass youpassword #on service iptables -A INPUT -s 47.8.16.30 -p tcp -m tcp --dport 873 -j ACCEPT ##******************* #自启动 chkconfig --level 345 rsyncd on

trouble shooting
1. uid=root gid=root 配置文件和 模块的目录属性要一致 不然传输会报错 rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1505) 2. client 密码文件 也得是600 3. address ip写得不对 启动不了 tail /var/log/message 23 17:02:44 localhost rsyncd[5345]: rsyncd version 3.0.6 starting, listening on port 873 Mar 23 17:02:44 localhost rsyncd[5345]: bind() failed: Cannot assign requested address (address-family 2) Mar 23 17:02:44 localhost rsyncd[5345]: unable to bind any inbound sockets on port 873 Mar 23 17:02:44 localhost rsyncd[5345]: rsync error: error in socket IO (code 10) at socket.c(541) [receiver=3.0.6] 4. 启动脚本添加 rm -f /var/run/rsyncd.pid 5.: @ERROR: chroot failed rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6] 原因: 服务器端的目录不存在或无权限。创建目录并修正权限可解决问题 6.restart 时起不来,log如下 [root@ ~]# cat /data/logs/rsync.log 2017/07/27 11:16:34 [21027] rsyncd version 3.0.6 starting, listening on port 873 2017/07/27 11:16:34 [21027] bind() failed: Address already in use (address-family 2) 2017/07/27 11:16:34 [21027] socket(10,1,6) failed: Address family not supported by protocol 2017/07/27 11:16:34 [21027] unable to bind any inbound sockets on port 873 2017/07/27 11:16:34 [21027] rsync error: error in socket IO (code 10) at socket.c(541) [receiver=3.0.6] 改为start 成功 最终的解决方案是 sleep 2 restart() { stop sleep 2 start } 7. 问题 restart后 其实有时进程不在 2017/08/02 18:09:49 [6875] bind() failed: Address already in use (address-family 2) 2017/08/02 18:09:49 [6875] unable to bind any inbound sockets on port 873 2017/08/02 18:09:49 [6875] rsync error: error in socket IO (code 10) at socket.c(541) [receiver=3.0.6] 为空 lsof -i:873 解决 查看了nginx的启动脚本后 得到启发 在启动脚本上加 sleep 2 8.查看log得知 Aug 2 17:30:13 localhost rsyncd[3232]: Badly formed boolean in configuration file: "on". Aug 2 17:30:13 localhost rsyncd[3232]: Unknown Parameter encountered: "pid flie" Aug 2 17:30:13 localhost rsyncd[3232]: IGNORING unknown parameter "pid flie" 小伙伴no 写成了 on ,file 写成了 flie 哈哈哈哈 期间还有 rsyslog 重启什么的 直接手工启动 rsync --daemon --config=$CFILE 9. rsync报错rsync: failed to set times on "." (in backup): Permission denied (13) 原创 还有 对应的模块 目录一定得是运行是apapche 因为rsyncd 运行用户是apapche 不行 rsync报错rsync: failed to set times on "."
