- 离线搭建集群pcs
- 添加解析
- 添加免密登录
- 离线包准备【2个主机同步】
- 安装pcs并启动服务【2个主机同步】
- 创建集群用户和密码【2个主机同步操作】
- 验证pcs运行，两个节点的用户注册到集群
- 配置集群名称mycluster和启动集群
- 状态检查及验证
- 检查集群配置的有效性
- 检查集群报错(unpack_resources) error...处理
- 在node1恢复后，为防止node2资源迁回node01（迁来迁去对还是会对业务有一定影响）
- 设置资源超时时间
- 执行命令修改如下2个内核参数 （需要root权限）
- 验证，正常无回显
- 启用nonlocal 绑定内核参数【两台主机均需要操作】
- 绑定vip
- 绑定chronyd服务
- 验证vip和自动迁移
- vip验证
- 自动迁移验证
Pacemaker详解 & pcs命令详解和参数说明
- 内容太多，放一起太卡，所以Pacemaker详解 & pcs命令详解和参数说明放到下面这篇文章中
【下面参数或使用更多方法都可以见这篇文章】
Pacemaker详解、pcs命令详解和参数说明、centos8或bclinux8.2离线安装pcs以及搭建pcs、pcs的使用说明
环境说明
- 简单来说，pcs命令就是创建VIP集群用的。给2台主机绑定一个vip。
今天说的是离线安装，系统是bclinux8.2,【内核是4.19，理论centos8以上的系统通用这种方法】 - 主机1

离线搭建集群pcs
搭建不难pcs，难的是找包。
添加解析
- 添加2个主机的解析和vip的解析【vip的主机名是自定义的】
- 主机1
[root@xz-sj-dmz-1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

[root@xz-sj-dmz-2 ~]#
添加免密登录
- 主机1和主机2之间是创建了免密登录的，已经操作过了，页面没了就不放命令过程了。
如果不会的翻下我笔记，有说如何创建ssh免密登录。【不做这个操作可能也行，只是下面操作的2台主机我做了免密登录】
离线包准备【2个主机同步】
-
包名，我下面已经放出来了，如果不想折腾的，可以直接下载我准备的包，下载地址如下：rpms-chrony-pcs-packages.rpm.rar
【下面其实就是在有外网的情况下汇总了corosync pacemaker pcs fence-agents resource-agents这些包放在一个文件夹拷贝到内网环境，用dnf来安装的（centos7的版本也可以到有公网的机子上汇总拷贝到内网服务器上用rpm安装，下面用的是dnf，其实也可以用rpm来安装，注：如果用rpm安装，命令最好分开存放到文件夹，分别用rpm安装）】 -

执行命令修改如下2个内核参数 （需要root权限）
- 主要针对http服务，如果不是http服务，则不用执行。
sysctl -w net.ipv4.tcp_timestamps=1开启对于TCP时间戳的支持,若该项设置为0，则下面一项设置不起作用sysctl -w net.ipv4.tcp_tw_recycle=1表示开启TCP连接中TIME-WAIT sockets的快速回收- 为避免后面启动集群的时候出现这个报错

[root@xz-sj-dmz-1 ~]# reboot
- 节点2已经可以看到vip了，一切正常。
再将节点2关机，看vip是否能自动回迁到节点1上，如果可以，则正常。
