搭建多节点ceph.docVIP

1、更新ceph sudo apt-get install ceph ceph-common ceph-mds 由于版本过旧问题，选择更新source #sudo wget -q -O- /git/?p=ceph.git;a=blob_plain;f=keys/release.asc | sudo apt-key add - #sudo echo deb /debian/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list # sudo apt-get update sudo apt-get install ceph 节点IP 配置主机名 sudo gedit /etc/hostname（可能必须修改） sudo gedit /etc/hosts 配置免密码访问（略）——ssh 创建ceph配置文件 /etc/ceph/ceph.conf [global] max open files = 131072 ??? #For version 0.55 and beyond, you must explicitly enable? ??? #or disable authentication with auth entries in [global]. ??? auth cluster required = none ??? auth service required = none ???auth client required = none [osd] ???osd journal size = 1000 ???#The following assumes ext4 filesystem. filestore xattr use omap = true ??? #For Bobtail (v 0.56) and subsequent versions, you may? ??? #add settings for mkcephfs so that it will create and mount ??? #the file system on a particular OSD for you. Remove the comment `#`? ??? #character for the following settings and replace the values? ??? #in braces with appropriate values, or leave the following settings? ??? #commented out to accept the default values.
