[Service]
...
LimitNOFILE=10000
LimitNPROC=10000
启动mariadb
# systemctl daemon-reload
# systemctl enable mariadb.service
# systemctl start mariadb.service
查看mariadb连接数是否生效(还是没到10000)
[root@controller1 data(keystone_admin)]# mysql -uroot -popenstack -e "show variables like '%connections%';"

初始化mariadb，按照提示，输入合适的root密码(这里root密码为openstack)
# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

3. Ceph
3.1 cephadm
Cephadm使用容器和systemd安装并管理Ceph集群，并与CLI和仪表板GUI紧密集成。
- cephadm仅支持Octopus和更高版本。
- cephadm与新的业务流程API完全集成，并完全支持新的CLI和仪表板功能来管理集群部署。
- cephadm需要容器支持（podman或docker）和Python 3。
cephadm部署和管理Ceph集群。它是通过SSH将管理器守护程序连接到主机来实现的。管理器守护程序能够添加，删除和更新Ceph容器。 cephadm不依赖于Ansible，Rook和Salt等外部配置工具。
cephadm管理Ceph集群的整个生命周期。此生命周期从引导过程开始，当cephadm在单个节点上创建一个微小的Ceph群集时。该群集由一台监视器和一台管理器组成。 cephadm然后使用业务流程界面（“第2天”命令）扩展集群，添加所有主机并配置所有Ceph守护程序和服务。可以通过Ceph命令行界面（CLI）或通过仪表板（GUI）来执行此生命周期的管理。
cephadm是Ceph v15.2.0（Octopus）版本中的新增功能，并且不支持Ceph的旧版本。

3.2.5 启用ceph cli
ceph shell会进入装好ceph软件包的容器中, 设置个alias，方便使用
[root@ceph-1 ~]# ./cephadm shell -- ceph status
[root@ceph-1 ~]# vim /etc/bashrc
alias ceph='cephadm shell -- ceph'
也可以在宿主机上安装ceph-common(可选)
[root@ceph-1 ~]# cephadm add-repo --release octopus
[root@ceph-1 ~]# cephadm install ceph-common
3.2.6 注册节点
把第一个mon节点上产生的ssh公钥拷贝到新节点上
[root@ceph-1 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.80.185
[root@ceph-1 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.80.213
注册新节点, 会自动扩展成monitor和manager
[root@ceph-1 ~]# ceph orch host add ceph-2
[root@ceph-1 ~]# ceph orch host add ceph-3
查看ceph纳管的所有节点
[root@ceph-1 ~]# ceph orch host ls
HOST ADDR LABELS STATUS
ceph-1 ceph-1
ceph-2 ceph-2
ceph-3 ceph-3
移除注册节点
# ceph orch host rm <host>
3.2.7 部署mon(可选)
上述注册节点的步骤会自动部署mon，所以以下步骤可跳过。
一个典型的ceph集群一般有3个或5个monitor进程，如果集群规模达到5个节点及以上的话，建议部署5个monitor进程
设置ceph public_network网络
# ceph config set mon public_network *<mon-cidr-network>*
默认情况下，向群集中添加新主机时，cephadm会自动最多添加5个mon, 可修改默认mon数量
[root@ceph-1 ~]# ceph orch apply mon 3
Scheduled mon update...
部署mon到指定的节点上
[root@ceph-1 ~]# ceph orch apply mon *<host1,host2,host3,...>*
禁止自动部署mon
# ceph orch apply mon --unmanaged
3.2.8 部署osd
再注册两个节点
[root@ceph-1 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.80.203
[root@ceph-1 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.80.90
[root@ceph-1 ~]# ceph orch host add ceph-4
[root@ceph-1 ~]# ceph orch host add ceph-5
自动添加所有可用设备(貌似没有效果，故手动指定添加osd)
[root@ceph-1 ~]# ceph orch apply osd --all-available-devices
指定节点指定设备创建osd
[root@ceph-1 ~]# ceph orch daemon add osd ceph-1:/dev/vdb
[root@ceph-1 ~]# ceph orch daemon add osd ceph-2:/dev/vdb
[root@ceph-1 ~]# ceph orch daemon add osd ceph-3:/dev/vdb
[root@ceph-1 ~]# ceph orch daemon add osd ceph-4:/dev/vdb
[root@ceph-1 ~]# ceph orch daemon add osd ceph-5:/dev/vdb
显示集群主机上所有的存储设备清单
[root@ceph-1 ~]# ceph orch device ls

3.2.9 部署mds
指定节点部署mds
[root@ceph-1 ~]# ceph orch apply mds cephfs --placement="3 ceph-1 ceph-2 ceph-3"
Scheduled mds.cephfs update...
cephfs需要两个存储池，一个存储文件，另一个存储文件的元数据
[root@ceph-1 ~]# ceph osd pool create cephfs_data 128 128
pool 'cephfs_data' created
[root@ceph-1 ~]# ceph osd pool create cephfs_metadata 128 128
pool 'cephfs_metadata' created
手动创建cephfs
[root@ceph-1 ~]# ceph fs new cephfs cephfs_metadata cephfs_data
new fs with metadata pool 4 and data pool 3
查看cephfs
[root@ceph-1 ~]# ceph fs ls
name: cephfs, metadata pool: cephfs_metadata, data pools: [cephfs_data ]
挂载cephfs
[root@ceph-3 ~]# mkdir -p /mnt/cephfs/
[root@ceph-3 ~]# mount -t ceph 172.16.80.45:/ /mnt/cephfs -o name=admin,secret=AQBrBKZgarHxAxAAQm2TL1KM3gkW7zr5A2yZgw==

配置完后，ceph dashboard上就可以操作Object Gateway了
安装s3cmd命令行客户端
[root@ceph-3 ~]# yum install s3cmd -y
配置s3cmd（172.16.80.90:80是radosgw监听的地址端口）
[root@ceph-3 ~]# s3cmd --configure
Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.
Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key: 45FW7W30MHJOH8633464
Secret Key: DIvMiQl3AzllCSyEEn8TuoDFCKaHFt7QqGMXzqnU
Default Region [US]:
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: 172.16.80.90:80
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: 172.16.80.90:80/%(bucket)s
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]: no
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:
New settings:
Access Key: 45FW7W30MHJOH8633464

Use HTTPS protocol: False
HTTP Proxy server name:
HTTP Proxy server port: 0
Test access with supplied credentials? [Y/n] y
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)
Now verifying that encryption works...
Not configured. Never mind.

3.2.11 部署nfs-ganesha
ceph推荐使用nfs-ganesha来提供nfs服务
创建nfs池
# ceph osd pool create nfs-ganesha 64 64
创建nfs-ganesha
[root@ceph-1 ~]# ceph orch apply nfs nfs nfs-ganesha nfs-ns --placement="3 ceph-1 ceph-2 ceph-3"
Scheduled nfs.nfs update...
#启动application，不然会有warning告警
[root@ceph-1 ~]# ceph osd pool application enable nfs-ganesha nfs
enabled application 'nfs' on pool 'nfs-ganesha'
[root@ceph-1 ~]# ceph dashboard set-ganesha-clusters-rados-pool-namespace nfs-ganesha/nfs-ns
Option GANESHA_CLUSTERS_RADOS_POOL_NAMESPACE updated
cephfs的nfs是基于cephfs提供，所以在cephfs中创建一个/nfs目录，作为nfs服务的根目录
#1. 确保已挂载cephfs至/mnt/cephfs目录前提下
[root@ceph-3 ~]# mkdir -p /mnt/cephfs/nfs
#2. 登录https://172.16.80.45:8443/#/nfs，界面上创建nfs export
#3. 挂载nfs
[root@ceph-5 ~]# mount -t nfs 172.16.80.45:/nfs /mnt/
