Rsync usage guide
1. Backup in the window environment
1. Server side
Open https://devops.5ul.cn/download/ in the browser , and download rsync.zip to the local
Unzip and install
Unzip it, double-click the application. Choose OK all the way to the next step.
The picture shows that the installation is complete.
rsync configuration file
After installation, edit C:/program files(x86)/icw/rsync.conf
Modify to the following configuration:
use chroot = false
strict modes = false
hosts allow = 10.13.1.4 //对方ip地址
log file = rsyncd.log
port = 20003 //不设置默认为873
[wwwroot]
path = /cygdrive/d/wwwroot
read only = true
transfer logging = yes
uid = 0
gid = 0use chroot
Whether to lock the root directory before transmission, yes yes, no no. rsync for added security, the default value is yes.
hosts allow
Clients that are allowed to connect. Fill in the rsync client address according to the actual situation, and separate multiple ips with .
port
specifies the listening port.
log file
Log files, by default in the rsync installation directory.
[wwwroot]
module name
path
Path. The writing method of the path is fixed, and /cygdrive/ is unchanged, only need to modify the following parameters. For example, the D:\wwwroot\ directory of Windows is written as /cygdrive/d/wwwroot
read only
Whether it is read-only. As a server, it is recommended to enable it.
transfer logging
Log during transmission. It is recommended to enable
uid and gid
Specify user id and group id. 0 means anonymous.
policy restrictions
disable user
During this period, rsync will create a user and register the service to log in as this user. Due to the intranet transmission and the configuration of read-only permissions, the service is configured as anonymous access.
Open Computer Management, find Users and Groups, and disable the user.
firewall
Open the windows firewall, and let the port parameters specified in the above configuration file be released one by one. And only allow client ip access
service configuration
boot up
Find the RsyncServer in the service item and set it to start automatically at boot
Modify login options
找到该服务, 右键将 登陆身份 设置为 本地系统系统账户
启动服务
右键启动服务. 如果有报错信息, 检查日志文件.
2、客户端
- Linux
开始前的准备
查看端口是否可达
nc -zvw3 10.13.1.58 20003安装 rsync
yum install -y rsync同步数据
rsync -avzP --port=20003 [email protected]::wwwroot /data/vhost-bak/70-58/bak-9-07-09_18将服务端 wwwroot 模块下所配置的目录递归同步到 /data/vhost-bak/70-58/bak-9-07-09_18 目录下.
-a 表示以递归方式传输文件，并保持所有文件属性
-z 传输时压缩
-v 详细输出
-P 显示实时传输速率等状态
图为正在同步数据.
- windows
下载客户端
https://devops.5ul.cn/download/cwrsync_6.2.5_x64_free.zip下载完解压. 进入到目的备份目录
cd E:\tmp
E:\download\cwrsync_6.2.5_x64_free\bin\rsync.exe -avP --port=20003 10.11.1.131::wwwroot .windows下rsync直接指定目的目录会有问题. 所以 powershell 要先进入到 目的备份目录, 再执行备份命令
开始备份
备份完成
二、Linux环境下备份
服务端使用
安装
yum install -y rsync配置
cat > /etc/rsync.conf<<EOF
use chroot = false
strict modes = false
hosts allow = 10.13.1.4
log file = rsyncd.log
port = 20003
[wwwroot]
path = /data/wwwroot
read only = true
transfer logging = yes
uid = 0
gid = 0
EOF该文件与上文 windows的配置无异.
开启服务端
守护进程
服务端已守护进程的方式启动, 默认会找 /etc/rsync.conf 文件. 如果不是默认的该文件, 需要使用 --config=> <rsync_conf_file> 指定配置文件.
rsync --daemon --config=/etc/rsync.conf查看进程及端口
ps aux | grep rsync
root 336 0.0 0.0 114856 392 ? Ss 10:51 0:00 rsync --daemon --config=/etc/rsyncd.conf
netstat -antpl | grep rsync
tcp 0 0 0.0.0.0:20003 0.0.0.0:* LISTEN 336/rsync
tcp6 0 0 :::20003 :::* LISTEN 336/rsync服务端配置完毕. 记得防火墙放行对应端口.
客户端
安装
yum install -y rsync使用rsync端口同步
rsync -avP --port=20003 10.1.1.1:/wwwroot .基于ssh认证同步
rsync -avP -e "ssh -p 20002" [email protected]:/wwwroot .使用 -e "ssh -p 20002" 选项指定ssh端口, 不加该选项即使用22端口.
