一、首先两台服务器做hlim用户的免密ssh登录
su - hlim ssh-keygen -t rsa ssh-keygen -t rsa -f /home/hlim/.ssh/id_rsa -P ""
在目标服务器上执行，将另外一台服务器的/home/hlim/.ssh/id_rsa.pub内容复制到/home/hlim/^Csh/authorized_keys中
su - hlim vim .ssh/authorized_keys
二、验证免密登录
su - hlim ssh ip
三、配置lsync服务使用hlim用户运行
vim /usr/lib/systemd/system/lsyncd.service [Service] User=hlim Group=hl95 Type=simple
四、重启服务
ystemctl daemon-reload
systemctl start lsyncd.service
五、如果启动失败，手动执行服务，查看报错信息
su - hlim [hlim@ecs-szhyypt-itsm-07-0001 ~]$ /usr/bin/lsyncd -nodaemon /etc/lsyncd.conf 11:27:43 Normal: --- Startup --- Cannot open logfile [/var/log/lsyncd.log]!chmod 777 /var/log/lsyncd.log
chmod 777 /var/log/lsyncd.status
六、需要手动设置权限
[hlim@ecs-szhyypt-itsm-07-0001 ~]$ /usr/bin/lsyncd -nodaemon /etc/lsyncd.conf 11:28:45 Normal: --- Startup --- 11:28:45 Normal: recursive startup rsync: /home/hlim/imdata/ -> 10.40.131.22:/home/hlim/imdata/ excluding contmp log .gnome2 UnionTech OS Server 20 1050e sending incremental file list sent 299 bytes received 14 bytes 626.00 bytes/sec total size is 231,618 speedup is 739.99 11:28:45 Normal: Startup of "/home/hlim/imdata/" finished: 0
七、显示同步成功。设置开机自启动
systemctl enable lsyncd
