一、演示环境：
[root@mgr02 ~]# cat /etc/hosts
10.0.0.7 mgr02
10.0.0.131 mgr03
[root@mgr03 ~]# cat /etc/hosts
10.0.0.7 mgr02
10.0.0.131 mgr03二、服务器间免秘钥配置
在10.0.0.131 机器上安装 sshfs;通过sshfs 映射挂载10.0.0.7 机器上的/data1 目录到本地挂载点/mnt 下：
10.0.0.7 和10.0.0.131 机器上都执行# sshd-keygen -t rsa 生产秘钥对
拷贝10.0.0.131 上的公钥到10.0.0.7 上
[root@mgr03 ~]# ssh-copy-id -i .ssh/id_rsa.pub -p52110 [email protected]
[root@mgr03 ~]# cat .ssh/config
HOST 10.0.0.7
HostName mgr02
Port 52110
User root
IdentityFile ~/.ssh/id_rsa
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
[root@mgr03 ~]# ssh [email protected]
Warning: Permanently added '[mgr02]:52110,[10.0.0.7]:52110' (ECDSA) to the list of known hosts.
Last login: Wed Jul 10 07:30:55 2019 from mgr03
[root@mgr02 ~]#
[root@mgr02 ~]#
面秘钥配置成功了三、安装sshfs
此次演示采用 yum 安装sshfs
默认源无该工具，需要先安装EPEL源
yum install -y epel-release
yum -y install fuse-sshfs
[root@mgr03 ~]# which sshfs
/usr/bin/sshfs
[root@mgr03 ~]# cat /usr/lib/systemd/system/sshfs-diankezk.service
[Unit]
Description=SSHFS MOUNT mgr02 10.0.0.7
After=sshd.service
[Service]
Type=forking
ExecStart=/usr/bin/sshfs 10.0.0.7:/data1 /mnt -o reconnect -o cache=yes -o allow_other
ExecStop=/usr/bin/umount /mnt
[Install]
WantedBy=multi-user.target开机自启动挂载：
[root@mgr03 ~]# systemctl enable sshfs-diankezk.service
Created symlink from /etc/systemd/system/multi-user.target.wants/sshfs-diankezk.service to /usr/lib/systemd/system/sshfs-diankezk.service.
