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
 

2. client

iptables -A INPUT -s 10.45.241.123/32 -p tcp -m tcp  --dport  873 -j ACCEPT

#pull 
env RSYNC_PASSWORD=3636 rsync -avz s_20160928.sql.gz  [email protected]::data 

rsync -avz s_20160928.sql.gz  --delete  --password-file=rsyncd.secrets [email protected]::data 

/usr/bin/rsync -al -q --timeout=50 ${DB_BAK_ROOT} root@${BAK_SERVER}::${MODULE}/${IPADDR}

3.rsync daemon 启动脚本

sysd centos7

cat /usr/lib/systemd/system/rsyncd.service 
[Unit]
Description=fast remote file copy program daemon
ConditionPathExists=/etc/rsyncd.conf

[Service]
EnvironmentFile=/etc/sysconfig/rsyncd
ExecStart=/usr/bin/rsync --daemon --no-detach "$OPTIONS"

[Install]
WantedBy=multi-user.target

sysv centos6.x

#!/bin/bash
#
# rsyncd      This shell script takes care of starting and stopping
#             standalone rsync.
#
# chkconfig: - 99 50
# description: rsync is a file transport daemon
# processname: rsync
# config: /etc/rsyncd.conf
 
# Source function library
. /etc/rc.d/init.d/functions
 
RETVAL=0
rsync="/usr/bin/rsync"
prog="rsync"
CFILE="/etc/rsyncd.conf"

start() {
        # Start daemons.
        [ -x $rsync ] || \
            { echo "FATAL: No such programme";exit 4; }
        [ -f $CFILE ] || \
            { echo "FATAL: config file does not exist";exit 6; }
        echo -n $"Starting $prog: "
        daemon $rsync --daemon --config=$CFILE
        RETVAL=$?
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog
        echo
        return $RETVAL
}
 
stop() {
        # Stop daemons.
        echo -n $"Stopping $prog: "
        killproc $prog -QUIT
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog
       # [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/rsync && rm -f /var/lock/subsys/$prog &&  rm -f  /var/run/rsyncd.pid  /var/lock/subsys/rsync

        return $RETVAL
}
 
# call the function we defined
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart|reload)
        stop
        sleep 2
        start
        RETVAL=$?
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
  *)
        echo $"Usage: $0 {start|stop|restart|reload|status}"
        exit 2
esac
 
exit $RETVAL

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 "." (in backup): Permission denied (13) 原创 

10. on alpine docker 
+ env 'RSYNC_PASSWORD=7jKSNcSD2zN6AjJK' rsync -az '--port=873' '--password-file=/etc/lcpass' /var/jenkins_home/workspace/l/vue-wap/ [email protected]::lc-temp
rsync: [sender] could not open password file /etc/pass: Permission denied (13)
rsync error: syntax or usage error (code 1) at authenticate.c(188) [sender=3.2.3]
Post stage
[Pipeline]

11. ERROR: password file must not be other-accessible
  密码文件得当前用户的权限的同时 600 所以在 alpine  dokcer里 先用普通用户创建 再用root 去chmod 600 passwordfile 

12.
2022/01/12 10:42:43 [22994] rsync: failed to write xattr user.rsync.%stat for "." (in sync-task): Permission denied (13)
2022/01/12 10:42:43 [22994] rsync: failed to set times on "." (in core-sync-task): Operation not permitted (1)
2022/01/12 10:42:43 [22994] ./

整个/data/nginx 全改为 apache用户权限
