hghac和hgproxy版本升级相关操作和注意事项

环境

系统平台：N/A
版本：4.5.6,4.5.7,4.5.8

文档用途

本文档用于高可用集群环境中hghac组件和hgproxy组件替换和升级操作

详细信息

1.关闭服务

所有数据节点都执行

1、关闭hgproxy服务

[root@hgdb01 tools]# systemctl stop hgproxy.service [root@hgdb02 tools]# systemctl stop hgproxy.service

2、关闭hghac服务

[root@hgdb01 tools]# systemctl stop hghac.service [root@hgdb02 tools]# systemctl stop hghac.service

3、关闭etcd服务

[root@hgdb01 tools]# systemctl stop etcd.service [root@hgdb02 tools]# systemctl stop etcd.service [root@localhost ~]# systemctl stop etcd.service

2.升级过程
操作前请先备份原集群配置文件。

1、安装软件包
验证md5值

[root@hgdb01 tools]# md5sum hghac4.2.3.3-see-17f931d-20240620.x86_64.rpm 0d960d0ac4925b272c30849e415031fd hghac4.2.3.3-see-17f931d-20240620.x86_64.rpm

安装软件包

[root@hgdb01 tools]# rpm -ivh hghac4.2.3.3-see-17f931d-20240620.x86_64.rpm 准备中... ################################# [100%] 正在升级/安装... 1:hghac-4.2.3.3-17f931d ################################# [100%] Created symlink from /etc/systemd/system/multi-user.target.wants/hghac.service to /usr/lib/systemd/system/hghac.service. Created symlink from /etc/systemd/system/multi-user.target.wants/etcd.service to /usr/lib/systemd/system/etcd.service. Created symlink from /etc/systemd/system/multi-user.target.wants/vip-manager.service to /usr/lib/systemd/system/vip-manager.service.

2、配置并启动etcd
01节点：

[root@hgdb01 tools]# vim /usr/local/hghac/etcd/etcd.yml # This is the configuration file for the etcd server. # Human-readable name for this member. name: 'etcd_01' # Path to the data directory.>
