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
