rsync 服务搭建

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
