标题: 手动安装ceph和使用（5） [打印本页]

如果报错：
Error in sys.exitfunc
解决方法
网上收集到一个解决方式，添加环境变量,在admin节点的shell中运行命令后重新运行deploy命令，不过我运行了感觉没生效

export CEPH_DEPLOY_TEST=YES
sudo ceph-deploy new ceph1 ceph2 ceph3

如果在当前目录使用命令ls看到三个配置文件，则可以无视这个错误继续安装。

[zzq@localhost myceph]$ ls
ceph.conf  ceph-deploy-ceph.log  ceph.mon.keyring
[zzq@localhost myceph]$

修改osd的副本数
将osd pool default size = 2添加至末尾

sudo vi /etc/ceph.conf

输入内容:

osd pool default size = 2

配置初始 monitor(s)、并收集所有密钥

sudo ceph-deploy mon create-initial

正确运行输出如下:

[zzq@localhost myceph]$ sudo ceph-deploy mon create-initial
