environment
Existing: CentOS 7.3 ( infrastructure server ) Ceph 10.2.7 (jewel)
Post-deployment: Calamari 1.3.3
introduce
Note: The introduction and rpm package are all from the blog of Mo Dashen http://www.zphj1987.com/ You deserve it!
The components included in Calamari mainly include calamari-server ; romana ; salt-minion ; salt-master ; diamond .
The respective roles of these modules:
Calamari-server provides a place to interact with the cluster and encapsulate its own API for centralized management. This only needs to be installed on a certain machine in the cluster, or it can be installed independently
romana is the original calamari-client , this is called client, it is actually a web interface, this is better called calamari-web , it has been renamed romana , this also only needs to be installed on a certain machine in the cluster, or you can Independent installation, this needs to be installed on a machine with calamari-server
salt-master is a management tool that can manage other machines in batches, and can manage machines with salt-minion installed . In a cluster, this is also installed with calamari-server
The salt-minion is installed on all nodes of the cluster. This is to receive instructions from the salt-master to operate on the machines in the cluster, and to feed back some information to the salt-master .
diamond is a collection control for the monitoring information of the system, which provides the monitoring of the hardware information of the cluster and the monitoring of the information of the cluster. The data is sent to the romana machine, and the carbon on the romana collects the data and stores it in the machine. in the database
Install
Description (must see!!!)
Node situation |
software installation required |
Calamari server |
calamri-server romana salt-master |
集群节点 |
salt-minion diamond |
如果在某集群节点安装calamari，则以上都需要安装
以下涉及的admin均为calamari 和salt-master服务端的hostname
本文不采用ceph-deploy calamari connect node 方式安装。
这一步通过自己观察发现是安装salt-minion和diamond软件并创建对应目录文件。
【因为采用的手工安装固定版本，因此可以舍弃。目录文件手动创建即可,见下文】
==============================calamari端=================================
1、软件包解压

以下链接更改了saltstack的repo文件,磨大神的貌似失效了
链接: http://pan.baidu.com/s/1pLPWkHl 密码: a8jx
# mkdir calamari && cd calamari
# unzip centosjewel.zip
# cd centosjewel/
2、添加saltstack 的repo文件
# mv saltstack-rhel7.repo /etc/yum.repos.d/
# yum clean all; yum repolist
3、安装calamari diamond romana
# yum localinstall
calamari-server-1.3.3-jewel.el7.centos.x86_64.rpm diamond-3.4.68-jewel.noarch.rpmromana-1.2.2-36_gc62bb5b.el7.centos.x86_64.rpm
4、调整目录权限
# chmod 777 -R /var/log/calamari/
# chmod 777 -R /opt/calamari/
5、salt的卸载与安装
卸载存在bug的salt版本并安装契合的salt版本（calamari依赖）
# rpm -e --nodeps salt-minion salt-master salt
# yum localinstall salt-2015.8.1-1.el7.noarch.rpm
# yum localinstall salt-master-2015.8.1-1.el7.noarch.rpm
# yum localinstallsalt-minion-2015.8.1-1.el7.noarch.rpm
需要先配置被监控端再继续calamari的相关操作！
===========================被监控端(集群节点)==============================
1、安装salt-minion diamond
1.1、添加saltstack 的repo文件
# mv saltstack-rhel7.repo /etc/yum.repos.d/
# yum clean all; yum repolist
1.2、安装
# yum localinstall
salt-2015.8.1-1.el7.noarch.rpm salt-minion-2015.8.1-1.el7.noarch.rpm diamond-3.4.68-jewel.noarch.rpm
2、配置salt-minion
2.1、修改minion文件（admin均为calamari的hostname）
# sed -i ‘s/#master: salt/master: admin/‘ /etc/salt/minion
2.2、添加minion.d附加目录及calamari.conf文件
# mkdir /etc/salt/minion.d/
# echo ‘master: admin’> /etc/salt/minion.d/calamari.conf
# systemctl restart salt-minion
# systemctl enable salt-minion
注意（坑）:
如果通过ceph-deploycalamari connect nodex安装， calamari.conf里的master 默认为None ，会导致salt-key -L 发现不了节点
salt-minion 必须有一个mon节点,否则也会报：
3、配置diamond
将host指向calamari服务端hostname
# cd /etc/diamond/ && cpdiamond.conf.example diamond.conf
# sed -i ‘/^host/s/graphite/admin/‘ /etc/diamond/diamond.conf
# systemctl restart diamond
# systemctl enable diamond
注：某些机子上面出现了systemctl无法识别diamond服务，在确保已经安装后添加即可
chkconfig --add diamond
============================calamari端（续）===============================
6、salt-master相关
！！！被监控端（集群节点）部署完成后再执行以下命令！！！
6.1重启
# systemctl restart salt-master
6.2 管理salt-minion节点
# salt-key -L 列出已发现的节点
# salt-key -A 允许所有节点加入
成功后由Unaccepted Keys 转为 Accepted keys下
6.3 检测节点
# salt ‘*‘ test.ping 检测链接性
如果出现如下报错，检查client端/etc/salt/minion.d/calamari.conf里的master项是否为calamari端的hostname
# salt ‘*‘ ceph.get_heartbeats 输出ceph集群信息(过多不贴了)
7、初始化calamari配置
# calamari-ctl initialize
管理界面的用户名和密码
8、web访问及后续问题
以上步骤均成功后在浏览器地址栏输入calamari server端IP登录(默认80端口)即可
如果出现以下错误（500）
清理配置再初始化一次
# calamari-ctl clear --yes-i-am-sure
# calamari-ctl initialize （无交互）
如果出现如下报错：
重启 被监控端的salt-minion和 diamond
以及 server 端的salt-master
