清空日志文件，重启服务

cd /var/log/ceph

没有按照官方文档执行网关安装有关？ceph-deploy install --rgw node..

但是这个版本的ceph-deploy指定的ceph版本太低，且是el6

解决 /var/lib/ceph/radosgw/ceph-rgw-ceph-0/keyring: (2) No such file or directory

查看/etc/ceph目录下的keyring文件，发现已生成了ceph.bootstrap-rgw.keyring

错误的路径/var/lib/ceph/radosgw/ceph-rgw-ceph-0/keyring

正确的路径/var/lib/ceph/radosgw/ceph-rgw.ceph-0/keyring

不知道为什么路径有一个符号错误

做个软连接

cd /var/lib/ceph/radosgw
ln -s ceph-rgw.ceph-0 ceph-rgw-ceph-0

错误：

重新执行部署

cd /etc/ceph
ceph-deploy rgw create ceph-0 ceph-1 ceph-2 ceph-3

重新部署后，会生成/var/log/ceph/ceph-client.rgw.ceph-0.log日志文件

其中有日志

设置默认pg_num pgs_num

/etc/ceph/ceph.conf

osd pool default size = 3
osd pool default min_size = 1
osd pool default pg num = 128
osd pool default pgp num = 128

重新部署(--overwrite-conf)

cd /etc/ceph
ceph-deploy --overwrite-conf rgw create ceph-0 ceph-1 ceph-2 ceph-3

故障依旧

成功的方案

删掉所有pool，重新部署，参考以下历史记录

652 ceph osd pool ls
653 ceph osd pool rm vdbench
654 ceph osd pool rm vdbench vdbench --yes-i-really-really-mean-it
655 ls /dev/

678 ceph -
679 ceph -s
680 cd /etc/ceph
681 ceph-deploy rgw create ceph-0
682 cat /var/log/ceph/ceph-client.rgw.ceph-0.log
683 systemctl status ceph-radosgw@rgw.ceph-0
再来一次集群环境的部署

cd /etc/ceph
ceph-deploy --overwrite-conf rgw create ceph-0 ceph-1 ceph-2 ceph-3

部分日志

ceph -s rgw已经起来了

======================

以下为参考官方文档的失败经理，留档参考

部署对象存储网关rgw（失败）

ceph-deploy install --rgw ceph-0 ceph-1 ceph-2 ceph-3

故障 Unable to find a match: epel-release

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y

故障Status code: 404

坑爹的阿里云镜像，没有epel 8，bclinux又是el8版本！

采用huawei epel镜像

[epel-everything]
name=huawei epel mirror
baseurl=https://repo.huaweicloud.com/epel/8/Everything/aarch64/
enabled=1
gpgcheck=0

yum install epel-release --nobest --skip-broken

ceph-deploy 会强制执行yum install epel-release(失败)

注释掉epel-release的安装

修改/usr/lib/python2.7/site-packages/ceph_deploy/hosts/centos/install.py 60行，注释掉epel-release的安装（前面已经手动--skip-broken安装好了）

生效了

故障 Unable to find a match: yum-plugin-priorities

参考上面思路，直接注释掉/usr/lib/python2.7/site-packages/ceph_deploy/hosts/centos/install.py 61,62行

自动找到老版本ceph-release-1-0.el6 Status code: 404

手动安装

修改/usr/lib/python2.7/site-packages/ceph_deploy/install.py

安装版本参数args.release = 'mimic' 改为 args.release = 'nautilus

关于python3版本

bclinux python3.7.9

cenos7 python3.6.8

openeuler 20.03 lts sp3 python 3.7.9
