rsync 服务搭建
服务端部署操作内容：
- 创建rsync用户和用户组
eg：
useradd -s /sbin/nologin -M rsync
- 创建需要备份的指定目录，并修改权限
eg：
mkdir -p /backup/
chown -R rsync:rsync /backup
- 创建rsync密码文件，录入密码并修改权限为600
eg：
echo "rsync_backup:passwd@123" >/etc/rsync.password ###注意：服务端的密码文件中包含认证用户和密码
chmod 600 /etc/rsync.password
- 修改配置文件/etc/rsyncd.conf
eg:
cat /etc/rsyncd.conf
uid = rsync
gid = rsync
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false
hosts allow = 192.168.217.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup ###认证用户
secrets file = /etc/rsync.password ###密码文件路径
[backup]
path = /backup
###可加其它模块###
服务端启动服务并加入开机启动项
启动服务：
rsync --daemon
rsync --daemon --config=/etc/rsyncd.conf
检查服务启动情况：
# netstat -anltup |grep 873
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 68849/rsync
tcp6 0 0 :::873 :::* LISTEN 68849/rsync
加入开机启动项：
echo "/usr/bin/rsync --daemon" >> /etc/rc.local
客户端部署操作内容：
创建rsync密码文件，录入密码并修改权限为600
eg：
echo "passwd@123" >/etc/rsync.paasword ###客户端密码文件只包含密码
chmod 600 /etc/rsync.paasword
完成部署后，创建文件测试：
服务端备份路径下文件检查：
cd /backup/ && ll
total 0
客户端创建测试文件：
echo "rsync file test 123" > rsync-test.txt
执行备份：
# rsync -avz -P rsync-test.txt rsync_backup@192.168.217.114::backup --password-file=/etc/rsync.password
sending incremental file list
rsync-test.txt

服务端检查备份情况：
# ll

# cat rsync-test.txt
