ceph集群 octups添加Monitor

添加Monitor

1. 在目标节点导出mon的钥匙环文件

 sudo -u ceph ceph auth get mon. -o /tmp/ceph.mon.keyring

2. 获取monmap并写入文件

sudo -u ceph ceph mon getmap -o /tmp/monmap

Note:

可以通过monmaptool --print /tmp/monmap显示文件内容

monmaptool: monmap file /tmp/monmap

3. 初始化mon目录

sudo -u ceph ceph-mon --mkfs -i $HOSTNAME --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring

Note:

sudo -u ceph ceph-mon [--cluster {cluster-name}] --mkfs -i $HOSTNAME --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring

4. 启动服务

sudo systemctl start ceph-mon@$HOSTNAME
sudo systemctl enable ceph-mon@$HOSTNAME

/etc/ceph/ceph.conf必须配置publick_network和cluster_network 方可启动服务
