ceph 安裝

使用的是fc12操作系統(tǒng)，內(nèi)核是2.6.33，先升級到2.6.36。起初在fc11上升級，make modules時(shí)遇到如下錯(cuò)誤 INSTALL /lib/firmware/bnx2/bnx2-rv2p-06-5.0.0.j3.fw
DEPMOD 2.6.36
/bin/sh: line 1: 15321 Segmentation fault /sbin/depmod -ae -F System.map 2.6.36

最后找了個(gè)fc12的系統(tǒng)，升級。

1. 下載ceph-0.29.1.tar.gz，解壓

cd ceph.0.29.1/
./autogen.sh
./configure
checking for NSS... yes
configure: using nss for cryptography
checking for FCGX_Init in -lfcgi... no
checking for fuse_main in -lfuse... no
configure: error: no FUSE found (use --without-fuse to disable)
=====> 安裝fuse,fuse-devel

checking for fuse_main in -lfuse... yes
checking for malloc in -ltcmalloc... no
configure: error: in `/home/ceph-0.29.1':
configure: error: no tcmalloc found (use --without-tcmalloc to disable)
====> yum install google-perftools-devel

hecking for FCGX_Init in -lfcgi... no
checking for fuse_main in -lfuse... yes

checking jni.h usability... no
checking jni.h presence... no
checking for jni.h... no
checking for LIBEDIT... no
configure: error: in `/home/ceph-0.29.1':
configure: error: No usable version of libedit found.
====>FC12的LIBEDIT是2.11，yum install libedit-devel

checking for jni.h... no
checking for LIBEDIT... yes
checking atomic_ops.h usability... no
checking atomic_ops.h presence... no
checking for atomic_ops.h... no
configure: error: in `/home/ceph-0.29.1':
configure: error: no libatomic-ops found (use --without-libatomic-ops to disable)
====>yum install libatomic_ops-devel

末了，

#make && make install ；這個(gè)過程有點(diǎn)慢

#cp ./src/sample.* /usr/local/etc/ceph/ ##拷貝ceph的配置文件，后面要修改

#mv /usr/local/etc/ceph/sample.ceph.conf /usr/local/etc/ceph/ceph.conf

#mv /usr/local/etc/ceph/sample.fetch_config /usr/local/etc/ceph/fetch_config

#修改/usr/local/etc/ceph/ceph.conf和/usr/local/etc/ceph/fetch_config文件，按照網(wǎng)上的要求，可以適當(dāng)?shù)囟啻蜷_log以了解ceph內(nèi)部實(shí)現(xiàn)。

#cp ./src/init-ceph /etc/init.d/ceph

#mkdir /var/log/ceph; ##存放log，現(xiàn)在ceph自己還不自動(dòng)建這個(gè)目錄

#mkdir /data ##存儲相應(yīng)信息，下面配置會用到

2. 打算用2臺MDS，2臺OSD，1臺AS+MON，所以上述的機(jī)器復(fù)制4臺。

在5臺機(jī)器上modporbe ceph

3. 兩臺OSD，加虛擬硬盤，格成btrfs格式
[root@ceph-osd59 ~]# mkfs.btrfs /dev/sdb

WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL

fs created label (null) on /dev/sdb

4. 然后在AS+MON上，創(chuàng)建文件系統(tǒng)，并啟動(dòng)

5. 在AS+MON機(jī)器上mount ceph文件系統(tǒng)

mkdir /ceph

mount.ceph 10.10.37.70:/ /ceph

【出現(xiàn)問題】

其中在mount的時(shí)候，出現(xiàn)error

> # dmesg -c
> libceph: no secret set (for auth_x protocol)
> libceph: error -22 on auth protocol 2 init

后來加上

[root@ceph-as-mon70 ceph-0.29.1]# cat /etc/ceph/keyring
[client.admin]
key = AQCVDghOOMZONRAANdh11UcePt5qxB+NMYDM3g==
auid = 18446744073709551615
[root@ceph-as-mon70 ceph-0.29.1]# mount.ceph 10.10.37.70:6789:/ /ceph -v -o name=admin,secret=AQCVDghOOMZONRAANdh11UcePt5qxB+NMYDM3g==
WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.
parsing options: name=admin,secret=AQCVDghOOMZONRAANdh11UcePt5qxB+NMYDM3g==
error adding secret to kernel client.admin : No such devicemount error 5 = Input/output error

也還是出錯(cuò)，

最后通過關(guān)掉SELINUX解決，修改/etc/selinux/config

SELINUX=disabled
#SELINUX=enforcing

重啟后[root@cephmds56 ~]# sestatus
SELinux status: disabled
