First, Rsync_service configuration

vim/etc/rsyncd.conf ====== Create the configuration file, configured as follows

==================================================

#rsyncd_config_______________start

# #rsyncd. conf start##

#rsync uid,gid=65534 (default)

# #rsync Start model ===== rsync--daemon

UID = rsync #固定rsync用户

GID = rsync#

Use chroot = no#

Max connections =#有多少客户端可以同时连本服务器

Timeout =#超时时间 300=300s

PID file =/var/run/rsyncd.pid#进程pid文件目录

Lock file =/var/run/rsync.lock#排队访问服务器端

Log file =/var/log/rsyncd.log#进程故障日志

[Oldboy] #模块 equivalent to a shared directory, you can also set up a multi-module method: Pull the module to the last side to increase

Path =/oldboy/#定义模块路径

Ignore errors#忽略错误

Read Only = False#相当于可读可写

List = False#允许列表

Hosts allow = 10.0.0.0/24#允许的主机

Hosts deny = 0.0.0.0/32#拒绝网段

Auth users = rsync_backup#虚拟用户, process user

Secrets file =/etc/rsync.password#用户对应的密码文件

#exclude =a b excludes files that are not allowed to upload a=filename b=filename

#rsync_config_______________end

==================================================

Start rsync:

Rsync--daemon

See if the port is correct = = Default: 873

Netstat-lntup|grep

Netstat-lntup|grep 873

Cat/var/log/rsyncd.log can also look at the boot log

Create the/oldboy directory in the configuration file

Mkdir/oldboy-p

Create rsync process user and give Oldboy owner

Useradd rsync-s/sbin/nologin

Chown-r rsync.rsync/oldboy/

Write the account password into the password configuration file and give 600 permissions (security privileges)

echo "rsync_backup:abu888" >/etc/rsync.password

chmod 600/etc/rsync.password

Server-side configuration is complete.

Client Configuration

Client is very simple, install a rsync, the password to the password file inside the password file to reduce the permissions to 600

Yum Install Rsync-y

echo "Dev.dev." >/etc/rsync.password

chmod 600/etc/rsync.password

Practice and Usage ———— | must be in client operation, server side is not executable

Access via rsync daemon: Process mode

Pull:rsync [OPTION ...] [[email protected]] Host::src ... [DEST]

1, Pull:rsync-avz [email protected]::oldboy//data1--password-file=/etc/rsync.password

rsync [OPTION ...] rsync://[[email protected]]host[:]/src ... [DEST]

2, Pull:rsync-avz rsync://[email protected]/oldboy/data1/--password-file=/etc/rsync.password

=============================================================================================================== =============

Push:rsync [OPTION ...] Src... [[email protected]] HOST::D EST

1, push:rsync-avz/data1/[email protected]::oldboy/--password-file=/etc/rsync.password

rsync [OPTION ...] SRC ... rsync://[[email protected]]host[:P ort]/dest

2, Push:rsync-avz/data1/rsync://[email Protected]/oldboy--password-file=/etc/rsync.password

Exclude single push:--exclude=filename exclude multiple with {Filename,filename} and so on

1, Rsync-avz--exclude={aaa.sh,oldboy,abu.sh}/data1/[email protected]::oldboy/--password-file=/etc/rsync.password

Exclude multiple, write filename that needs to be excluded into a file, and then use the filename created by--exclude-from=

2, Rsync-avz--exclude-from=/paichu.log/data1/[email protected]::oldboy/--password-file=/etc/rsync.password

Exclude single Rafa:--exclude=filename exclude multiple with {Filename,filename} and so on

Rsync-avz--exclude={abu.sh,oldboy} [email protected]::oldboy//data1/--password-file=/etc/rsync.password

Rsync-avz--exclude-from=/paichu.log/data1/[Email protected]::oldboy/--password-file=/etc/rsync.password

Exclude multiple, write filename that needs to be excluded into a file, and then use the filename created by--exclude-from=

Rsync-avz--exclude-from=/root/paichu.log [email protected]::oldboy//data1/--password-file=/etc/rsync.password

rsync Sync without differences

--deltet

Rsync-avz--delete/data1/[Email protected]::oldboy/--password-file=/etc/rsync.password

Rsync-avz--delete/[email protected]::oldboy//data1--password-file=/etc/rsync.password

rsyncServer Summary:

1, vi/etc/rsyncd.conf (user, directory, module, virtual user, and password file)

2. Create a shared directory/oldboy

3. Create rsync users. and authorized access to/oldboy/

4. Create a password file, copy the path in the configuration file, and then add the password content.

Content Virtual user name: password

5. password file permissions 600

6, rsync--daemon and then put into/etc/rc.local

7, Tail/var/log/rsyncd.log

Rsync Client (multiple)

1, the password file and the server does not have any relationship. command when

--password-file=/etc/rsync.password Content: Password

2,/etc/rsync.password 600

3. Execute push or pull with command

Exclude:

1. Firewalls and SELinux

2, look at the log/var/log/rsyncd.log

3, the entire deployment process to consider the overall troubleshooting.

4, operating habits as a major event.

Ways to Kill a process:

1, [[email protected] oldboy]# Cat/var/run/rsyncd.pid

4970

[[email protected] oldboy]# kill ' Cat/var/run/rsyncd.pid '

2, [[email protected] oldboy]# Pkill rsync
