5.20笔记整理 rsync 守护进程模式
Rsync daemon （rsyncd）
Daemon为守护进程，rsyncd运行在服务器端
服务器端操作：
1. 添加虚拟用户
[root@backup ~]# useradd -s /sbin/nologin -M rsync
2. 创建共享目录/data 修改所有者
[root@guanggege ~]# mkdir -p /data
[root@guanggege ~]# chown rsync.rsync /data
[root@guanggege ~]# ll -d /data
drwxr-xr-x 2 rsync rsync 6 May 5 18:33 /data
[root@guanggege ~]#
3. 创建密码文件，修改权限为600（密码文件都为600）
[root@guanggege ~]# echo 'rsync_backup:123456' >/etc/rsync.password
[root@guanggege ~]# chmod 600 /etc/rsync.password
[root@guanggege ~]# ll /etc/rsync.password
-rw------- 1 root root 20 May 21 09:44 /etc/rsync.password
[root@guanggege ~]# cat /etc/rsync.password
rsync_backup:123456
[root@guanggege ~]#
4. 修改rsync配置文件 /etc/rsync.conf
[root@guanggege ~]# vim /etc/rsyncd.conf
#Rsync server
##created by oldboy 15:01 2009-6-5
###rsyncd.conf start##
fake super = yes
uid = rsync
gid = rsync
use chroot = no
max connections = 2000
timeout = 600
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 = 10.0.0.0/24
##hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password

rsync配置文件下各行含义
5. 启动rsync服务端（rsyncd或rsyncd.service）
启动
[root@guanggege ~]# systemctl restart rsyncd
[root@guanggege ~]#
检查进程
[root@guanggege ~]# ps -ef |grep rsync
root 7514 1 0 09:51 ? 00:00:00 /usr/bin/rsync --daemon --no-detach
root 7516 7391 0 09:52 pts/0 00:00:00 grep --color=auto rsync
[root@guanggege ~]#
检查端口
[root@guanggege ~]# ss -lntup |grep rsync
tcp LISTEN 0 5 *:873 *:* users:(("rsync",pid=7514,fd=3))
tcp LISTEN 0 5 :::873 :::* users:(("rsync",pid=7514,fd=5))
[root@guanggege ~]#
6. 检查rsync服务端是否能用（自我检查）
[root@backup ~]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::data
Password:
sending incremental file list
hosts
sent 89 bytes received 49 bytes 30.67 bytes/sec
total size is 349 speedup is 2.53
[root@backup ~]#
7. 排查故障流程
看日志
[root@backup ~]# tail -f /var/log/rsyncd.log
2019/05/20 20:56:10 [8609] receiving file list
2019/05/20 20:56:10 [8609] sent 48 bytes received 263 bytes total size 234
2019/05/20 21:02:45 [8419] sent 0 bytes received 0 bytes total size 0
2019/05/21 09:58:01 [7857] params.c:Parameter() - Ignoring badly formed line in config file: ignore er
看配置文件是否有错误
Rsync客户端操作：
1. 创建密码文件（只需要密码即可），并改权限为600
[root@guanggege ~]# echo 123456 >/etc/rsync.password
[root@guanggege ~]# chmod 600 /etc/rsync.password
[root@guanggege ~]# ll /etc/rsync.password
-rw------- 1 root root 7 May 21 10:01 /etc/rsync.password
[root@guanggege ~]# cat /etc/rsync.password
123456
[root@guanggege ~]#
2. 检查
[root@nfs01 ~]# rsync -avz /etc/hostname rsync_backup@172.16.1.41::data --password-file /etc/rsync.passwd
sending incremental file list
sent 51 bytes received 20 bytes 47.33 bytes/sec
total size is 6 speedup is 0.08
[root@nfs01 ~]#
Rsync多模块
新建一个目录 /backup
[root@backup ~]# mkdir -p /backup
[root@backup ~]#
修改rsync配置文件，添加/backup模块
[root@backup ~]# vim /etc/rsyncd.conf
#Rsync server
#created by oldboy 15:01 2009-6-5
##rsyncd.conf start##
fake super = yes
uid = rsync
gid = rsync
use chroot = no
max connections = 2000
timeout = 600
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 = 10.0.0.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password

多个模块对应多个目录，每添加一个目录需要再添加模块
