手动部署 ceph mon (luminous 版)

本文主要是介绍手动部署 ceph mon (luminous 版)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

#环境

参考手动部署 ceph 环境说明 (luminous 版)

模板创建脚本

ceph.conf.template

[global]
fsid = $cephuuid
mon initial members = $cephmonhost
mon host = $cephmonipaddr
public network = $cephmonnetwork
cluster network = $cephdatanetwork
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = 2048
filestore xattr use omap = true
osd pool default size = 3
osd pool default min size = 1
osd pool default pg num = $cephpgnum
osd pool default pgp num = $cephpgpnum
osd crush chooseleaf type = 1
[osd]
osd journal = /var/lib/ceph/journal/ceph-\$id/journal    <- 这个变量符号需要保留, 因此 \$
osd journal size = 2048

生成 ceph.conf

[root@cephsvr-128040 ceph]# cat gen_ceph_conf.sh
#!/bin/bash
source parameter
eval "cat <<EOF
$(<ceph.conf.template)
EOF
" 2> /dev/null

参考下面执行效果

[root@cephsvr-128040 ceph]# . gen_ceph_conf.sh
[global]
fsid = xxxxxxxx-5d4d-4d3a-a3b2-04e73eff4ccd
mon initial members = cephsvr-128040,cephsvr-128214,cephsvr-128215
mon host = xx.199.128.40,xx.199.128.214,xx.199.128.215
public network = xx.199.128.0/22
cluster network = xxx.30.128.0/21
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = 2048
filestore xattr use omap = true
osd pool default size = 3
osd pool default min size = 1
osd pool default pg num = 1024
osd pool default pgp num = 1024
osd crush chooseleaf type = 1
[osd]
osd journal = /var/lib/ceph/journal/ceph-$id/journal
osd journal size = 2048
