配置文件解读
| 配置参数 | 参数说明 |
|---|---|
| uid = rsync | 指定rsync服务运行的时候，向磁盘进行读取和写入操作的操作者 |
| gid = rsync | 指定rsync服务运行的时候，向磁盘进行读取和写入操作的操作者 |
| use chroot = no | 进行数据同步存储时，安全相关参数，默认内网进行数据同步，可以关闭 |
| max connections = 200 | 定义向备份服务器进行数据存储的并发连接数 |
| timeout = 300 | 定义与备份服务器建立的网络连接，在多长时间没有数据传输时，就释放连接 |
| pid file = /var/run/rsyncd.pid | 服务程序运行时，会将进程的pid信息存储到一个指定的pid文件中 |
| lock file = /var/run/rsync.lock | 定义锁文件，主要用于配合max connections 参数，当达到最大连接就禁止继续访问 |
| log file = /var/log/rsyncd.log | 定义服务的日志文件保存路径信息 |
| [backup] | 指定备份目录的模块名称信息 |
| path = /backup | 指定数据进行备份的目录信息 |
| ignore errors | 在进行数据备份传输过程过程中，忽略一些I/O产生的传输错误 |
| read only = false | 设置对备份的目录的具有读写权限，即将只读模式进行关闭 |
| list = false | 确认是否可以将服务配置的模块信息，在客户端可以查看显示 |
| hosts allow = 172.16.1.0/24 | 设置备份目录允许进行网络数据备份的主机地址或网段信息，即设置白名单 |
| hosts deny = 0.0.0.0/32 | 设置备份目录禁止进行网络数据备份的主机地址或网段信息，即设置黑名单 |
| auth users = rsync_backup | 指定访问备份数据目录的认证用户信息，为虚拟定义的用户，不需要进行创建 |
| secrets file = /etc/rsync.password | 设置访问备份数据目录进行认证用户的密码文件信息，会在文件中设置认证用户密码信息 |
| [backup] | 指定模块名称，便于日后维护 |
| path=/backup | 在当前模块中，Daemon使用的文件系统或目录，注意目录权限和配置文件权限一直，防止读写出问题 |
| #exclude= | 排除文件或目录，相对路径 |
| [ftp] | 还可以添加其他模块 |
创建用户
[root@rsync-test-241 ~]# useradd rsync -s /sbin/nologin -M
[root@rsync-test-241 ~]# id rsync
uid=1000(rsync) gid=1000(rsync) 组=1000(rsync)
创建目录，修改属性
[root@rsync-test-241 ~]# mkdir /backup
[root@rsync-test-241 ~]# chown -R rsync.rsync /backup/
[root@rsync-test-241 ~]# ls -ld /backup/
drwxr-xr-x 2 rsync rsync 6 11月 15 16:19 /backup/
创建认证文件，授权
[root@rsync-test-241 ~]# echo "rsync_backup:mima666" > /etc/rsync.password
[root@rsync-test-241 ~]# cat /etc/rsync.password
